City of Santa Ana 7‐Eleven Convenience Store and Service Station Project Initial Study/Mitigated Negative Declaration Introduction
FirstCarbon Solutions 1 Y:\Publications\Client (PN‐JN)\0327\03270041\ISMND\03270041 City of Santa Ana 7‐Eleven Store ISMND.docx
SECTION 1: INTRODUCTION
1.1 ‐ Purpose
The purpose of this Initial Study/Mitigated Negative Declaration (IS/MND) is to identify any potential
environmental impacts from implementation of the proposed 7‐Eleven Convenience Store and
Service Station Project in the City of Santa Ana, California. Pursuant to California Environmental
Quality Act (CEQA) Guidelines Section 15367, the City of Santa Ana is the Lead Agency in the
preparation of this IS/MND and any additional environmental documentation required for the
project. The City also has discretionary authority over the proposed project. The intended use of this
document is to determine the level of environmental analysis required to adequately analyze the
project pursuant to the requirements of CEQA and to provide the basis for input from public
agencies, organizations, and interested members of the public.
The remainder of this section provides a brief description of the project location and the primary project
characteristics. Section 2 includes an environmental checklist that provides an overview of the potential
impacts that may result from project implementation, elaborates on the information contained in the
environmental checklist, and provides justification for each checklist response. References cited in this
IS/MND are included in Section 3, and Section 4 contains the List of Preparers.
1.2 ‐ Project Location
The project site is located in the City of Santa Ana, Orange County, California. Santa Ana is
surrounded by the City of Orange to the north, the City of Tustin to the east, the City of Irvine to the
southeast, the City of Costa Mesa to the south, the cities of Fountain Valley and Westminster to the
west, and the City of Garden Grove to the northwest (Exhibit 1).
The project site is located at 1904 West First Street in Santa Ana. The project site is approximately
17,336 square feet or 0.40 acre and contains an existing approximately 1,610‐square‐foot restaurant
building with an associated parking lot. The project site comprises a single parcel designated by the
County of Orange as Assessor’s Parcel Number (APN) 007‐332‐07 (Exhibit 2).
1.3 ‐ Environmental Setting
The 0.40‐acre project site is a rectangular‐shaped parcel that is relatively flat and located in an urban
area. The project is bounded by single‐family residences and commercial uses to the north, single‐
family residences and auto‐body repair uses to the east, commercial and auto‐repair uses to the
west, and a vacant lot south of the project site. West First Street is located directly to the north of
the project site, and South Daisy Avenue is located directly to the east. The Santa Ana River is located
approximately 0.85 mile east of the project site, and based on the general area topography and
existing surface conditions; general surface water flow is expected to be to the south‐southwest.

1.3.1 ‐ General Plan
As shown in Exhibit 3, the 1998 City of Santa Ana General Plan Land Use Map designates the project
site as General Commercial (GC). The GC designation applies to commercial corridors in Santa Ana
including those located along Main Street, Seventeenth Street, Harbor Boulevard, and other major
arterial roadways in the City. The intensity standard applicable to this designation is a floor area ratio
of 0.5–1.0, though most General Commercial districts have a FAR of 0.5. A total of 888.3 acres of
land is included in this designation (City of Santa Ana 1998).
General Commercial districts are key components in the economic development of the City. They
provide highly visible and accessible commercial development along the City’s arterial transportation
corridors. In addition, General Commercial land uses provide important neighborhood facilities and
services, including shopping, recreation, cultural and entertainment activities, employment, and
education. These districts also provide support facilities and services for industrial areas, including
office and retail, restaurants, and various other services (City of Santa Ana 1998).
1.3.2 ‐ Zoning
As shown in Exhibit 4, the 2019 City of Santa Ana Zoning Map currently zones the project site as
Light Industrial (M‐1). The proposed project would seek an Amendment Application (Zone Change)
to change the zoning from Light Industrial (M‐1) to General Commercial (C‐2). The C‐2 zoning
permits a convenience store with the approval and issuance of a Conditional Use Permit for the
after‐hours operations.
1.4 ‐ Project Description
The proposed project consists of removing the existing approximately 1,610‐square‐foot restaurant
building and surface parking lot to construct a new 2,480‐square‐foot convenience store (7‐Eleven)
with an 810‐square‐foot gas station canopy. The gas station canopy includes two fuel pumps that
would accommodate up to four vehicles at a time, and the installation of two new 20,000‐gallon
double wall fiberglass underground storage tanks (USTs) with three dispensers. The new USTs would
be installed at a depth of approximately 17 feet below the ground surface (bgs) and located adjacent
to the west side of the proposed gas station canopy. The proposed project would also include an
associated parking lot with ten parking spaces, including one ADA space, and provide approximately
2,795 square feet of landscaping (Exhibit 5).
As a design feature, the project would remove the damaged sidewalk, curb, gutter, and bus pad
panel and construct a new commercial driveway along the project frontage on West First Street, per
City standards. Along South Daisy Street, the project would remove the damaged sidewalk, curb, and
gutter and construct a new sidewalk, curb, and gutter per City standards.
The proposed project would be completed in one phase, and the anticipated start date of demolition
is October 2019 and anticipated construction completion is April 2020. Once operational, the project
would operate 24 hours a day, 7 days a week.

1.4.1 ‐ Site Access
There are currently two unsignalized driveways that provide access to the project site, one located
on West First Street and a gated exit‐only driveway located on Daisy Avenue. Proposed site access
for the project would be provided via three unsignalized driveways, one located on West First Street
and two located on Daisy Avenue.
1.4.2 ‐ Utilities
The project applicant would install an underground infiltration system in conjunction with the
construction of a new 7‐Eleven convenience store and fuel station canopy in order to retain drainage
patterns. Recommendations from the Geotechnical Investigation Report (Appendix D) will also be
incorporated in the design and construction of the project, such as designing pavement and slopes
to ensure adequate drainage away from the structures.
The proposed project would be served by required public services and utilities including electricity,
natural gas, sewage, water, and solid waste removal, etc. Any existing underground utilities or
unsuitable materials on the project site would either be completely removed or rerouted within the
proposed construction areas. Table 1 lists the Utility Providers for the proposed project site.

1. Aesthetics Except as provided in Public Resources Code Section 21099, would the project:
a) Have a substantial adverse effect on a scenic vista?
b) Substantially damage scenic resources, including, but not limited to, trees, rock outcroppings, and historic building within a state scenic highway?
c) In non‐urbanized areas, substantially degrade the existing visual character or quality of public views of the site and its surroundings? (Public views are those that are experienced from publicly accessible vantage point). If the project is in an urbanized area, would the project conflict with applicable zoning and other regulations governing scenic quality?
d) Create a new source of substantial light or glare which would adversely affect day or nighttime views in the area?
Environmental Setting
The project is located in a highly urbanized area. The Census Bureau defines an Urbanized Area (UA)
as one with a population of 50,000 or more people (US Census 2018). An estimated 334,136 people
live in the City (US Census 2019). According to the Santa Ana General Plan, scenic resources in the
City of Santa Ana include views of the Santa Ana Mountains (City of Santa Ana 1982). Additional
regional corridors in the City of Santa Ana include the Santa Ana River and Santiago Creek, which are
part of the County Open Space network. The project is located approximately 0.86 mile east of the
Santa Ana River and approximately 1.68 miles south of Santiago Creek. According to California’s
Scenic Highway Mapping System, there are no designated Scenic Highways within the project
vicinity. The project site is located in an urbanized area adjacent to west First Street with high levels
of existing light. The adjacent commercial, residential, and light industrial uses generate light and
glare along all sides of the project site.

Environmental Evaluation
Would the project:
a) Have a substantial adverse effect on a scenic vista?
Less than significant impact. The project site is located in an urbanized area of Santa Ana that
supports a mix of development, including commercial, residential, and light industrial land uses. The
project proposes to develop a one‐story 7‐Eleven convenience store and fuel station canopy.
According to the site plan dated September 17, 2018, the convenience store would be 26 feet and 4
inches tall. The building height and fuel station canopy would be required to comply with the City of
Santa Ana Municipal Code Section 41‐379, which states that no structure shall exceed 35 feet in
height in the C‐2 zoning area. The project is located in the vicinity of the Santa Ana River and
Santiago Creek, which are approximately 0.86 mile and approximately 1.68 miles away, respectively.
The implementation of the proposed 7‐Eleven would not obstruct current views of the Santa Ana
Mountains, as the building and canopy heights would be consistent with the surrounding land uses.
As such, the project would not have a substantial adverse effect on scenic vistas within the area;
therefore, impacts would be less than significant.
b) Substantially damage scenic resources, including, but not limited to, trees, rock outcroppings,
and historic building within a state scenic highway?
Less than significant impact. According to the Scenic Corridor Element of the City’s General Plan, as
well as California’s Scenic Highway Mapping System, there are no designated Scenic Highways in the
City of Santa Ana (California Department of Transportation [Caltrans] 2019). The project site is
currently in an urbanized built‐up area.
A letter was provided by the City dated April 18, 2019 regarding the determination of historical
significance for the building on‐site and is included in Appendix C. The letter states that the subject
building was constructed in 1960 as a drive‐in restaurant. In 1978, an addition was constructed to
the front of the building to increase dining and serving capacity, and in 1981, arches around the
restaurant windows were constructed that significantly altered the physical aesthetics of the
building. Over the years, the restaurant was occupied by multiple business owners and has been
vacant since 2016. The letter concludes that the building is not eligible for inclusion in the California
Register of Historical Resources, nor is it eligible for the Santa Ana registry because the property fails
to meet the California Register Significance Criteria. Thus, the existing building on the project site
does not qualify as a “historical resource” for the purposes of CEQA.
Furthermore, there are ornamental street trees along south Daisy Avenue that would remain and no
scenic resources are present on‐site. Additionally, the project site and surrounding area are not
characterized by unique visual resources or historic structures, and, therefore, less than significant
impacts would occur to scenic or historic resources.

c) In non‐urbanized areas, substantially degrade the existing visual character or quality of public
views of the site and its surroundings? (Public views are those that are experienced from publicly
accessible vantage point). If the project is in an urbanized area, would the project conflict with
applicable zoning and other regulations governing scenic quality?
No impact. Because the project is located in an urbanized area, this analysis will discuss whether the
project would conflict with applicable zoning and other regulations governing scenic quality. The City of
Santa Ana General Plan and Zoning Ordinance defines the permitted land uses and the
corresponding development standards within the City. The project site is currently zoned as Light
Industrial (M‐1) and the City of Santa Ana General Plan designation is General Commercial. Although
service stations are permitted in the M‐1 zone, a convenience store greater than 2,000‐square‐feet
in size is not permitted in the M‐1 zone. Therefore, the proposed project would seek an Amendment
Application (Zone Change) to change the zoning from M‐1 to General Commercial (C‐2) to allow for a
2,480‐square‐foot convenience store. The C‐2 zoning permits a convenience store with the approval
and issuance of a Conditional Use Permit for the after‐hours operations. The surrounding parcels
north and east of the project site are zoned C‐2, therefore a zone change would be consistent with
the existing surrounding General Plan and Zoning designations. Furthermore, the proposed project
would comply with all City code requirements related to scenic quality as part of the design review
to ensure the project design is consistent with the surrounding uses. As such, the proposed project
would not conflict with applicable zoning and other regulations pertaining to scenic quality and no
impacts would occur.
d) Create a new source of substantial light or glare which would adversely affect day or nighttime
views in the area?
Less than significant impact. The project site is located in an urbanized area with high levels of
existing light. The adjacent commercial, residential, and roadway uses generate light and glare along
all sides of the property. Existing sources of lighting in the immediate vicinity of the project include
street lighting, and neighborhood businesses and residences. The project proposes to develop a new
one‐story 7‐Eleven convenience store and fuel station canopy, and would comply with all City code
requirements related to the height and design of lighting fixtures to ensure that light spillage onto
adjacent properties does not occur. Impacts related to light and glare would be less than significant.
Mitigation Measures
None.

Agriculture and Forestry Resources In determining whether impacts to agricultural resources are significant environmental effects, lead agencies may refer to the California Agricultural Land Evaluation and Site Assessment Model (1997) prepared by the California Dept. of Conservation as an optional model to use in assessing impacts on agriculture and farmland. In determining whether impacts to forest resources, including timberland, are significant environmental effects, lead agencies may refer to information compiled by the California Department of Forestry and Fire Protection regarding the state’s inventory of forest land, including the Forest and Range Assessment Project and the Forest Legacy Assessment project; and forest carbon measurement methodology provided in Forest Protocols adopted by the California Air Resources Board. Would the project:
a) Convert Prime Farmland, Unique Farmland, or Farmland of Statewide Importance (Farmland), as shown on the maps prepared pursuant to the Farmland Mapping and Monitoring Program of the California Resources Agency, to non‐agricultural use?
b) Conflict with existing zoning for agricultural use, or a Williamson Act contract?
c) Conflict with existing zoning for, or cause rezoning of, forest land (as defined in Public Resources Code Section 12220(g)), timberland (as defined by Public Resources Code Section 4526), or timberland zoned Timberland Production (as defined by Government Code Section 51104(g))?
d) Result in the loss of forest land or conversion of forest land to non‐forest use?
e) Involve other changes in the existing environment which, due to their location or nature, could result in conversion of Farmland, to non‐agricultural use or conversion of forest land to non‐forest use?
Environmental Setting
Agricultural Resources
The California Department of Conservation (DOC) Farmland Mapping and Monitoring Program
(FMMP) was established by the State Legislature in 1982 to assess the location, quality, and quantity
of agricultural lands and conversion of these lands over time. The FMMP has established five
farmland categories:

Prime Farmland (F) is farmland with the best combination of physical and chemical features
able to sustain long‐term agricultural production. This land must have been used for irrigated
agricultural production at some time during the last four years before the mapping date and have
the ability to store moisture in soil well.
Farmland of Statewide Importance (S) is similar to Prime Farmland but contains greater slopes
and a lesser ability to store soil moisture.
Unique Farmland (U) is usually irrigated, but may include non‐irrigated orchards or vineyards
as found in some climate zones in California. This land must still have been cropped some time
during four years prior to the mapping date.
Farmland of Local Importance (L) is important to the local agricultural economy as determined
by each county’s board of supervisors and local advisory committee.
Grazing Land (G) is land on which the existing vegetation is suited to the grazing livestock. This category was developed in cooperation with the California Cattlemen’s Association, University
of California Cooperative Extension, and other groups interested in the extent of grazing
activities.
According to the FMMP Orange County Important Farmland 2016, the City of Santa Ana does not
contain any Prime Farmland, Unique Farmland, or Farmland of Statewide Importance parcels (DOC
2016). No farmland or agricultural activity exists on or in the vicinity of the project site. The City of
Santa Ana is designated Urban and Built‐Up Land by the FMMP, which is defined as land that is
occupied by structures with a building density of at least one unit to 1.5 acres, or approximately six
structures to a 10‐acre parcel.
The Williamson Act, codified in 1965 as the California Land Conversation Act, allows local governments
to enter into contracts with private landowners, offering tax incentives in exchange for an agreement
that the land will remain undeveloped or related open space use only for a period of 10 years.
Additionally, according to the Williamson Act map for Orange County FMMP, the project site is not
under a Williamson Act contract and there are no Williamson Act lands in the vicinity (DOC 2012).
Forest Resources: CEQA requires the evaluation of forest and timber resources where those
resources are present; however, the project site is located within a commercial area of Santa Ana,
and there is no forest land as described in Public Resources Code Section 12220(g), timberland as
defined by Public Resources Code Section 4526, or property zoned for Timberland Production as
defined by Government Code Section 51104(g) on the site or in its vicinity.

Environmental Evaluation
Would the project:
a) Convert Prime Farmland, Unique Farmland, or Farmland of Statewide Importance (Farmland), as
shown on the maps prepared pursuant to the Farmland Mapping and Monitoring Program of the
California Resources Agency, to non‐agricultural use?
No impact. There is currently no Prime Farmland, Unique Farmland, or Farmland of Statewide
Importance (Farmland) within the City of Santa Ana. Therefore, impacts related to Prime Farmland,
Unique Farmland, or Farmland of Statewide Importance (Farmland) would not occur.
b) Conflict with existing zoning for agricultural use, or a Williamson Act contract?
No impact. There is currently no land in Santa Ana zoned for agricultural use or under a Williamson
Act contract. According to the Santa Ana General Plan, the proposed project site is zoned M‐1 and is
seeking to rezone the project site as C‐2. As such, the proposed project would not conflict with
existing zoning for agricultural use or a Williamson Act contract, and no impacts would occur.
c) Conflict with existing zoning for, or cause rezoning of, forest land (as defined in Public Resources
Code Section 12220(g)), timberland (as defined by Public Resources Code Section 4526), or
timberland zoned Timberland Production (as defined by Government Code Section 51104(g))?
No impact. CEQA requires the evaluation of forest and timber resources where those resources are
present; however, the project site is located in an urban built‐up area, and there is no forest or
timberland in the vicinity. There would therefore be no associated impacts.
d) Result in the loss of forest land or conversion of forest land to non‐forest use?
No impact. The project is located in an urban built‐up area; there is no forest land within the vicinity
of the project site. There would be no associated impact.
e) Involve other changes in the existing environment which, due to their location or nature, could
result in conversion of Farmland, to non‐agricultural use or conversion of forest land to non‐
forest use?
No impact. As mentioned above, there is no Farmland or forest land within the vicinity of the project
site, which is located in an urban built‐up area in the City of Santa Ana. The project therefore would
not induce the conversion of Farmland to non‐agricultural uses or the conversion of forest land to
non‐forest use.

3. Air Quality Where available, the significance criteria established by the applicable air quality management district or air pollution control district may be relied upon to make the following determinations. Would the project:
a) Conflict with or obstruct implementation of the applicable air quality plan?
b) Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is non‐attainment under an applicable federal or State ambient air quality standard?

d) Result in other emissions (such as those leading to odors) adversely affecting a substantial number of people?
Environmental Evaluation
Where available, the significance criteria established by the applicable Air Quality Management
District (AQMD) or Air Pollution Control District may be relied upon to make the following
determinations.
Would the project:
a) Conflict with or obstruct implementation of the applicable air quality plan?
Less than significant impact. The project is located in the South Coast Air Basin (SoCAB), where the
area is regulated by the South Coast Air Quality Management District (SCAQMD). The Environmental
Protection Agency (EPA) is responsible for identifying non‐attainment and attainment areas for each
criteria pollutant within the Air Basin. The Air Basin is designated as nonattainment for the National
Ambient Air Quality Standards (NAAQS) for 8‐hour ozone and particulate matter 2.5 micrometers or
less in diameter (PM2.5) and for the California Ambient Air Quality Standards (CAAQS) for 8‐hour
ozone, particulate matter 10 micrometers or less in diameter (PM10) and PM2.5.
To address regional air quality standards, the SCAQMD has adopted air quality strategies and
measures in their most recent plan, the 2016 Air Quality Management Plan (2016 AQMP). The 2016
AQMP, adopted in March 2017, serves as the regional air quality plan for the SoCAB to attain and
achieve the NAAQS. Some policy objectives of the 2016 AQMP include eliminating reliance on future
technologies measures to the maximum extent possible by providing specific control measures

which have quantifiable emissions reductions and associated costs and include developing a strategy
with fair‐share emission reductions at the deferral, state, and local levels.
To evaluate whether or not a project conflicts with, or obstructs the implementation of the 2016
AQMP, the SCAQMD CEQA Air Quality Handbook states that there are two key indicators. The
indicators identified by the criteria are discussed below.
1. Indicator: Whether the project will not result in an increase in the frequency or severity of
existing air quality violations or cause or contribute to new violations, or delay timely
attainment of air quality standards or the interim emission reductions specified in the air
quality management plan.
2. Indicator: According to Chapter 12 of the SCAQMD CEQA Air Quality Handbook, the purpose of
the General Plan consistency findings is to determine whether a project is inconsistent with the
growth assumptions incorporated into the air quality plan, and thus, whether it would interfere
with the region’s ability to comply with federal and California air quality standards.
Considering the recommended criteria in the CEQA Handbook, this analysis uses the following
criteria to address the indicators above and determine the project’s significance:
Criterion 1: Project’s contribution to air quality violations (SCAQMD’s first indicator);
Criterion 2: Assumptions in AQMP (SCAQMD’s second indicator); and
Criterion 3: Compliance with applicable emission control measures in the AQMPs.
Criterion 1: Project’s Contribution to Air Quality Violations
If a project’s emissions exceed the SCAQMD regional thresholds for nitrogen oxides (NOX), volatile
organic compounds (VOC), PM10, or PM2.5, it follows that the emissions could cumulatively
contribute to an exceedance of a pollutant for which the basin is in nonattainment (ozone, PM10,
PM2.5) at a monitoring station in the basin. An exceedance of a nonattainment pollutant at a
monitoring station would not be consistent with the goals of the AQMP—to achieve attainment of
pollutants. As discussed in Impact AIR‐2 and AIR‐3, the project would not exceed the regional and
localized significance thresholds. Therefore, the project would be consistent with the AQMP. The
project meets this criterion, and impacts would be less than significant.
Criterion 2: Assumptions in AQMP
The development of emission burdens used in AQMPs to demonstrate compliance with ambient air
quality standards is based, in part, on land use patterns contained within local general plans.
Therefore, it is reasonable to conclude that if a project is consistent with the applicable general plan
land use designation, and if the general plan was adopted prior to the applicable AQMP, then the
growth of vehicle miles traveled (VMT) and/or population generated by said project would be
consistent with the growth in VMT and population assumed within the AQMP. As previously
discussed in Section 1, the City of Santa Ana General Plan land use designation on the project site is
General Commercial (GC) and the current zoning designation on the site is Light Industrial (M1).

Y:\Publications\Client (PN‐JN)\0327\03270041\ISMND\03270041 City of Santa Ana 7‐Eleven Store ISMND.docx
The project is consistent with the general plan GC land use designation. The project would require a
zoning amendment to change its designation from M1 to General Commercial (C‐2) in order to allow
the development of the 7‐Eleven convenience store. The project site currently contains an existing
vacant restaurant. Because the existing and proposed zoning differ, the VMT for the existing and
proposed land uses were estimated to determine consistency with the land use designation.
Table 2 shows the estimated annual VMT under two scenarios: (1) developed as a 2,700–square‐foot
fast food restaurant without drive‐thru, consistent with the zoning designation and existing land use;
and (2) developed in accordance with the proposed project. As shown in Table 2, the project would
reduce annual VMT compared to the allowable uses under the existing zoning designation.
Table 2: Vehicle Miles Traveled Comparison
Scenario Total Annual VMT
Project site developed as fast food restaurant without drive‐thru, consistent with the current General Plan designation1
3,336,253
Project site developed in accordance with the proposed project 1,539,937
Notes: VMT = vehicle miles traveled 1 Land use permitted by the City’s current M1 zoning designation. The current GC General Plan
designation permits a floor area ratio (FAR) of 0.5, which would allow for a maximum of approximately 8,600 square feet. However, as a conservative measure, 2,700 square feet size is utilized, which is approximately the size of the existing vacant restaurant structure on‐site.
Source of existing general plan land use designation VMT: CalEEMod output for 2,700‐square‐foot fast food restaurant without drive‐thru. Source of project VMT: CalEEMod output based on assumptions consistent with the 1904 West First Street 7‐Eleven Convenience Market and Gas Station Traffic Site Analysis Report prepared by RK Engineering Group (2018). See Appendix A for complete CalEEMod outputs.
Because the project would not increase the VMT generated by the project site compared to the
assumptions used in the AQMP, it is reasonable to conclude that the growth supported by the
project is accounted for in the AQMP. The project would have less than significant impacts under this
criterion.
Criterion 3: Control Measures
The AQMP contains a number of control measures, which are enforceable requirements through the
adoption of rules and regulations. The project would comply with all applicable SCAQMD rules and
regulations. Therefore, the project complies with this criterion and would not conflict with or
obstruct implementation of the applicable air quality attainment plan.
Summary
In summary, the project would not exceed the growth assumptions in the AQMP. The project would
not result in a regional or localized exceedance of criteria air pollutants and would comply with all
applicable SCAQMD rules and regulations. Accordingly, the proposed project would not conflict with
or obstruct implementation of the applicable air quality plans, and, therefore, the impact would be
less than significant.

b) Result in a cumulatively considerable net increase of any criteria pollutant for which the project
region is non‐attainment under an applicable federal or State ambient air quality standard
(including releasing emissions, which exceed quantitative thresholds for ozone precursors)?
Less than significant impact. This impact is related to regional criteria pollutant impacts. However, by
its nature, air pollution is largely a cumulative impact resulting from emissions generated over a large
geographic region. The nonattainment status of regional pollutants is a result of past and present
development within the air basin, and this regional impact is a cumulative impact. In other words, new
development projects (such as the proposed project) within the air basin would contribute to this
impact only on a cumulative basis. No single project would be sufficient in size, by itself, to result in
nonattainment of regional air quality standards. Instead, a project’s emissions may be individually
limited, but cumulatively considerable when taken in combination with past, present, and future
development projects.
The cumulative analysis focuses on whether a specific project would result in cumulatively
considerable emissions. According to Section 15064(h)(4) of the CEQA Guidelines, the existence of
significant cumulative impacts caused by other projects alone does not constitute substantial evidence
that the project’s incremental effects would be cumulatively considerable.
Rather, the determination of cumulative air quality impacts for construction and operational emissions
is based on whether the project would result in regional emissions that exceed SCAQMD regional
thresholds of significance for construction and operations on a project level. Projects that generate
emissions below the SCAQMD significance thresholds would be considered consistent with regional air
quality planning efforts and would not generate cumulatively considerable emissions. As previously
mentioned, the nonattainment regional criteria pollutants of concern are ozone, PM10, and PM2.5.
Ozone is not emitted directly into the air but is a regional pollutant formed by photochemical reactions
in the atmosphere. Ozone precursors, VOC and NOX, react in the atmosphere in the presence of
sunlight to form ozone. Therefore, the SCAQMD does not have a recommended ozone threshold, but it
does have thresholds of significance for VOC and NOX.
Potential impacts would result if there were exceedances of State or federal standards for NOX, carbon
monoxide (CO), or particulate matter (PM10 and PM2.5). NOX emissions are of concern because of
potential health impacts from exposure to NOX emissions during both construction and operation
and as a precursor in the formation of airborne ozone. CO emissions are of concern during project
operation because CO hotspots can be related to increases in on‐road vehicle congestion. PM10 and
PM2.5 are of concern during construction because of the potential to emit exhaust emissions from
the operation of off‐road construction equipment and fugitive dust during earth‐disturbing activities
(construction fugitive dust).
The California Emissions Estimator Model (CalEEMod) Version 2016.3.2 was used to estimate the
projects construction and operational emissions. CalEEMod is designed to provide a consistent
platform for government agencies, land use planners, and environmental professional to quantify
potential criteria pollutant and greenhouse gas (GHG) emissions associated with construction and

operation activities from a variety of land use projects. The current version of CalEEMod uses
OFFROAD and EMFAC2014 emission factors.
The project’s regional construction and operational emissions, which include both on‐site and off‐
site emissions, are described and evaluated separately below.
Construction Regional Emissions
Construction emissions are described as “short‐term” or temporary in duration; however, they have
the potential to represent a significant impact with respect to air quality. Construction of the project
would result in the temporary generation of VOC, NOX, CO, SOX, PM10, and PM2.5 emissions from
construction activities such as demolition, grading, building construction, architectural coating, and
asphalt paving. Fugitive PM dust emissions are primarily associated with earth disturbance and
grading activities, and vary as a function of soil silt content, soil moisture, wind speed, acreage of
disturbance area, and miles traveled by construction vehicles on‐site and off‐site. Construction‐
related NOX emissions are primarily generated by exhaust emissions from heavy‐duty construction
equipment, material and haul trucks, and construction worker vehicles. VOC emissions are mainly
generated by exhaust emissions from construction vehicles, off‐gas emissions associated with
architectural coatings and asphalt paving.
For the purposes of this analysis, construction of the project is anticipated to begin in October 2019
and last 7 months. The construction equipment is currently unknown, and is thus based on
CalEEMod defaults. The duration of construction activity and associated equipment represent a
reasonable approximation of the expected construction fleet as required by the CEQA Guidelines.
Full construction emissions modeling parameters and assumptions are provided in Appendix B.1.

SCAQMD significance thresholds.

As shown in Table 3, the project’s regional daily construction emissions would not exceed any of
SCAQMD’s thresholds of significance. Therefore, the short‐term construction emissions would not
result in a cumulatively considerable net increase of any criteria pollutant for which the project
region is non‐attainment under an applicable federal or State ambient air quality standard.
Operational Regional Emissions
Following construction of the project, long‐term operational emissions would be generated, resulting
from the day‐to‐day operations. Operational emissions for land use development projects are typically
distinguished as mobile‐, area‐, and energy‐source emissions. Mobile‐source emissions are those
associated with automobiles that would travel to and from the project site. Area‐source emissions are
those associated with natural gas combustion for space and water heating, landscape maintenance
activities, and periodic architectural coatings. Energy‐source emissions are those associated with
electricity consumption and are more pertinent for GHG emissions than air quality pollutants.

seasons. For detailed assumptions, methodologies, and models used to estimate emissions, please

on maximum VOC limits of 0.15 pounds of VOC per 1,000 gallons from the loading of gasoline into storage tanks, and 0.38 pounds of VOC per 1,000 gallons from the dispensing of gasoline into vehicle fuel tanks. It was conservatively estimated that the gas station would have an annual throughput of 1 million gallons of gasoline.
Source: CalEEMod and FCS, see Appendix B.1. Emissions may vary slightly due to rounding.
As shown in Table 4, the project’s regional daily operational emissions would not exceed any of
SCAQMD’s thresholds of significance. Therefore, the long‐term daily operational emissions do not
result in a cumulatively considerable net increase of any criteria pollutant for which the project
region is non‐attainment under an applicable federal or State ambient air quality standard and
impacts are less than significant.
c) Expose sensitive receptors to substantial pollutant concentrations?
Less than significant impact. This impact evaluates the potential for the project’s construction and
operational emissions to expose sensitive receptors to substantial pollutant concentration. Sensitive
receptors are defined as those individuals who are sensitive to air pollution including children, the
elderly, and persons with preexisting respiratory or cardiovascular illness. For purposes of CEQA, the
SCAQMD considers a sensitive receptor to be a location where a sensitive individual could remain for
24 hours, such as residences, hospitals, or convalescent facilities (SCAQMD 2009). Commercial and
industrial facilities are not included in the definition because employees do not typically remain on‐site
for 24 hours. However, when assessing the impact of pollutants with 1‐hour or 8‐hour standards (such
as NO2 and CO), commercial and/or industrial facilities would be considered sensitive receptors.
For the proposed project, the closest sensitive receptors are the single‐family residences to the
north and eastern border of the project site. This analysis evaluates the potential for construction‐
and operational‐related criteria air pollutant, ozone precursor, and toxic air contaminant (TAC)
emissions to impact sensitive receptors.
Localized Significance Threshold Analysis—Criteria Pollutants
The localized construction and operational analyses use thresholds (i.e., localized significance
thresholds [LSTs]) that represent the maximum emissions for a project that would not cause or
contribute to an exceedance of the most stringent applicable federal or state ambient air quality
standard (SCAQMD 2009). If the project’s construction or operational emissions are under those

thresholds, it follows that the project would not cause or contribute to an exceedance of the
standard and would not expose sensitive receptors to substantial pollutant concentrations.
Localized Construction Analysis
The LST Methodology only applies to on‐site emissions and states that “off‐site mobile emissions from
the project should not be included in the emissions compared to LSTs.”1 Therefore, for purposes of the
construction LST analysis, only on‐site emissions were compared with the applicable LSTs.
Table 5 presents the project’s maximum daily on‐site emissions compared with the applicable LSTs.
The LSTs have been obtained from the LST Methodology for a project located in the SCAQMD
defined Source Receptor Area 17, a 1‐acre project site, and the nearest sensitive receptor being less
than 25 meters away. Emissions estimates account for implementation of SCAQMD Rule 403, which
is required for all projects regardless of significance.

construction‐related criteria air pollutant and ozone precursor concentrations would not expose
sensitive receptors to substantial pollutant concentrations. The impact would be less than significant.
Localized Operational Analysis
Similar to the construction LST analysis above, the applicable operational LSTs were obtained for a
project located in SRA 17, a 1‐acre project site, and the nearest sensitive receptor being less than 25
meters away.
As described above, the LST Methodology recommends that only on‐site emissions are evaluated
using LSTs. Because a majority of the project’s mobile‐source emissions would occur on the local and
regional roadway network away from the project, only the on‐site area‐, energy‐, and mobile‐source
emissions were included in this analysis. Six percent of the CalEEMod calculated mobile source
emissions was used to account for on‐site emissions from mobile sources, which accounts for vehicle
emissions that occur within approximately a half mile of the project site, and was included to
provide for a worst‐case analysis. Table 6 presents the project’s maximum daily on‐site emissions
compared with the applicable LSTs.

As shown in Table 6, the project’s maximum daily on‐site operational emissions would not exceed
any of the applicable SCAQMD LSTs. Therefore, the project’s operational activities would not cause
or contribute substantially to an existing or future ambient air quality standard violation.
Accordingly, the project’s operational criteria air pollutant and ozone precursor concentrations
would not expose sensitive receptors to substantial pollutant concentrations.
Toxic Air Contaminants
A TAC is defined as an air pollutant that may cause or contribute to an increase in mortality or
serious illness, or which may pose a hazard to human health. TACs are usually present in minute

FirstCarbon Solutions 31 Y:\Publications\Client (PN‐JN)\0327\03270041\ISMND\03270041 City of Santa Ana 7‐Eleven Store ISMND.docx
quantities in the ambient air; however, their high toxicity or health risk may pose a threat to public
health even at low concentrations.
Some studies indicate that diesel particulate matter (DPM) poses the greatest health risk among the
TACs listed above. A 10‐year research program California Air Resources Board (ARB 1998)
demonstrated that DPM from diesel‐fueled engines is a human carcinogen and that chronic (long‐
term) inhalation exposure to DPM poses a chronic health risk.
The dose to which receptors are exposed is the primary factor used to determine health risk and is a
function of concentration and duration of exposure. According to the Office of Environmental Health
Hazard Assessment, health risk assessments that determine the health risks associated with exposure
of residential receptors to TAC emissions should be based on a 30‐year exposure period, and health
risk assessments that address the health risk associated with exposure of children to TAC emissions
should be based on a 9‐year exposure period. TAC exposure to children is of special concern because
children typically metabolize more air per unit of body weight in comparison to adults, and they can be
more sensitive to toxics during development. However, health risk assessments should be limited to
the period/duration of activities associated with the emissions activity.
Toxic Air Pollutants—Construction
The construction period and potential exposure duration from construction activities would last
approximately 7 months, which is less than 2 percent of the total exposure time of 30 years for a
health risk assessment prepared in accordance with guidance from the SCAQMD. The proposed
project would not involve any highly intensive construction activities, and significant earthmoving
activities that would require substantial construction equipment are not anticipated as necessary for
the proposed project. Therefore, based on the relatively short construction period and intermittent
nature of construction emissions, the period of time that sensitive receptors would potentially be
exposed to short‐term construction activities would not rise to a “dose” level that would result in a
health hazard or exceed applicable standards.
Toxic Air Pollutants—Operations
Common sources of TACs include high traffic freeways, distribution centers, large fueling stations,
and dry cleaners. Operation of the project would not include those uses and therefore would not
emit TACs. Additional information regarding the project’s gas dispensing component is provided
below.
The ARB Air Quality and Land Use Handbook contains recommendations that will “help keep
California’s children and other vulnerable populations out of harm’s way with respect to nearby
sources of air pollution” (ARB 2005), including recommendations for distances between sensitive
receptors and certain land uses. The recommendation for siting fueling stations is as follows.
Fueling stations. The ARB recommends avoiding new sensitive land uses within 300 feet of a
large fueling station (a facility with a throughput of 3.6 million gallons per year or greater). A
50‐foot separation is recommended for typical gas dispensing facilities.

Y:\Publications\Client (PN‐JN)\0327\03270041\ISMND\03270041 City of Santa Ana 7‐Eleven Store ISMND.docx
Proposed mechanical ventilation systems could be located as close as 125 feet from the nearest off‐
site noise‐sensitive receptor, which is the single‐family residential home located at 109 South Daisy
Avenue. That distance is greater than the 50‐foot separation recommended for typical gas
dispensing facilities. SCAQMD has developed estimates of cancer risks from industry‐wide source
categories, including retail gasoline dispensing facilities. The methodology used to estimate those
risks are consistent with SCAQMD Rule 1401 and (2) California Air Pollution Control Officer
Association risk assessment guidance for gasoline service stations. At a distance of 125 feet from the
proposed gas station pump, the nearest sensitive receptor would be exposed to a cancer risk of 2.43
in one million (SCAQMD 2007a).2 TAC emissions created from charbroilers at the proposed fast food
restaurants are negligible, and would result in a less than significant cancer risk. The proposed
project conservatively estimates a throughput of 1 million gallons per year and, therefore, does not
qualify as a “large fueling station.” The project would be subject to annual throughput reporting
required by the SCAQMD. Furthermore, the project would be subject to State and regional
requirements for vapor recovery systems to control gasoline emissions. Based on the distance to the
nearest sensitive receptors and adherence to regulations, impacts would be less than significant.
Carbon Monoxide Hotspot Analysis
Project trips would contribute to vehicle volumes at existing and future local intersections. Local
mobile‐source CO emissions and concentrations near roadway intersections are a direct function of
traffic volume, speed, and delay. Transport of CO is extremely limited because it disperses rapidly
with distance from the source under normal meteorological conditions. However, under specific
meteorological conditions, CO concentrations near roadways and/or intersections may reach
unhealthy levels with respect to local sensitive land uses, such as residential units, hospitals, schools,
and childcare facilities.
With the turnover of older vehicles, introduction of cleaner fuels and implementation of more
stringent emissions control technology, CO concentrations in the SCAQMD have steadily declined. CO
is not a pollutant of concern in the region and all air monitoring stations in the Air Basin have
discontinued monitoring for this pollutant in the last 3 years.
Nevertheless, as part of the demonstration of CO attainment for the SoCAB (2003 Air Quality
Management Plan and 1992 Federal Attainment Plan for Carbon Monoxide), SCAQMD evaluated
potential CO exceedance throughout the air basin. As discussed in the 1992 CO Plan, peak CO
concentrations in the SoCAB are due to unusual meteorological and topographical conditions, and
not due to the impact of particular intersections. In the 1992 CO Plan, SCAQMD performed a CO
hotspot analysis for the four busiest intersections in Los Angeles at the AM and PM peak‐hour. The
busiest intersection (Wilshire Boulevard and Veteran Avenue), which had traffic volumes of
approximately 100,000 vehicles per day, was determined not to generate a CO hotspot even at peak
AM and PM conditions. Thus, intersections with fewer than 100,000 vehicles per day would also not
be anticipated to result in a CO hotspot.
2 The estimate of 2.43 in a million is based on the estimated cancer risk from Anaheim, which is the closest service station in Table 3
of the SCAQMD document, a 30‐meter receptor distance, and a 1 million gallon per year throughput volume.

FirstCarbon Solutions 33 Y:\Publications\Client (PN‐JN)\0327\03270041\ISMND\03270041 City of Santa Ana 7‐Eleven Store ISMND.docx
The First Street 7‐Eleven Convenience Market and Gas Station Traffic Site Analysis Report identified
the peak‐hour traffic volumes for six intersections affected by the project (RKEG 2018). As identified
in the Traffic Site Analysis, the maximum peak‐hour intersection volume would occur at the
intersection of Raitt Street and West First Street during PM peak hour. The estimated cumulative
traffic volume at this intersection is 4,505 PM peak‐hour trips. Using a conservative factor of 10 to
calculate daily vehicles, this maximally impacted intersection would service approximately 45,050
vehicles per day, which is substantially less than the 100,000 vehicles determined in SCAQMD’s CO
hotspot analysis. Furthermore, this peak hourly intersection traffic volume would be less than other
air district CO hotspot screening values such as those of the Bay Area Air Quality Management
District (44,000 vehicles per hour) and the Sacramento Metropolitan Air Quality Management
District (31,600 vehicles per hour). Therefore, the Project Plus Cumulative traffic would not
contribute a substantial amount of traffic to existing or future intersections that could result in a CO
hotspot. Therefore, the operational CO impact would be less than significant.
d) Result in other emission (such as those leading to odors) adversely affecting a substantial
number of people?
Less than significant impact. Odors can cause a variety of responses. The impact of an odor is
dependent on interacting factors such as frequency (how often), intensity (strength), duration (in
time), offensiveness (unpleasantness), location, and sensory perception. While offensive odors rarely
cause any physical harm, they still can be very unpleasant, leading to considerable distress and often
generating citizen complaints to local governments and regulatory agencies. Odor‐related symptoms
reported in a number of studies include nervousness, headache, sleeplessness, fatigue, dizziness,
nausea, loss of appetite, stomach ache, sinus congestion, eye irritation, nose irritation, runny nose,
sore throat, cough, and asthma exacerbation (SCAQMD 2007).
The SCAQMD’s role is to protect the public’s health from air pollution by overseeing and enforcing
regulations (SCAQMD 2007). The SCAQMD’s resolution activity for odor compliance is mandated
under California Health and Safety Code Section 41700, and falls under SCAQMD Rule 402. This rule
on Public Nuisance Regulation states: “A person shall not discharge from any source whatsoever such
quantities of air contaminants or other material which cause injury, detriment, nuisance, or
annoyance to any considerable number of persons or to the public, or which endanger the comfort,
repose, health or safety of any such persons or the public, or which cause, or have a natural
tendency to cause, injury or damage to business or property.”
The SCAQMD does not provide a suggested screening distance for a variety of odor‐generating land
uses and operations. However, the San Joaquin Valley Air Pollution Control District (SJVAPCD) does
have a screening distance for odor sources. Those distances are used as a guide to assess whether
nearby facilities could be sources of significant odors. Projects that would site a new receptor farther
than the applicable screening distances from an existing odor source would not be likely to have a
significant impact. These screening distances by type of odor generator are listed in Table 7.

Construction‐related Odors
Potential sources that may emit odors during construction activities include exhaust from diesel
construction equipment. However, because of the temporary nature of these emissions, the
intermittent nature of construction activities, and the highly diffusive properties of diesel PM
exhaust, nearby receptors would not be affected by diesel exhaust odors associated with project
construction. Odors from these sources would be localized and generally confined to the immediate
area surrounding the proposed project site. The proposed project would utilize typical construction
techniques, and the odors would be typical of most construction sites and temporary in nature.
Operational‐related Odors
The project would develop a convenience market with gas pumps, which are not typical odor‐
generating land uses. Land uses typically considered associated with odors include wastewater
treatment facilities, waste‐disposal facilities, or agricultural operations. Minor sources of odors, such
as exhaust from mobile sources, are not typically associated with numerous odor complaints, but are
known to have temporary and less concentrated odors. The project could also result in odor from
dispensing gasoline. The gas pumping areas are located over 125 feet from the nearest sensitive
receptors; therefore, the odors from dispensing gasoline are not expected to be detectible to off‐site
sensitive receptors. Considering the low intensity of potential odor emissions, the project’s
operational activities would not expose receptors to objectionable odor emissions.

The Project as a Sensitive Receptor
As a convenience market with gas pumps, the project is not considered a sensitive receptor site and
would not have the potential to place sensitive receptors near existing odor sources.
The project would not result in other emissions that could adversely affect a substantial number of
people; therefore, impacts are less than significant.

Less than significant impact with mitigation incorporated. A site reconnaissance visit was
conducted on February 28, 2018, by FCS Environmental Specialist, Brittany Hagen. Existing

conditions on the project site were documented, habitats on the project site were identified, and
their potential to sustain special‐status species was evaluated. The project site is fully developed.
Vegetation observed on‐site is characteristic of urbanized areas and includes chicory (Cichorium
intybus), Russian thistle (Salsola iberica), dandelion (Taraxacum spp.), and several ornamental plants
in a planter along the northern periphery of the site along West First Street. The immediate project
site does not contain any trees; however, pine trees are located adjacent to the site on South Daisy
Avenue and West Walnut Street.
Special‐Status Plant Species
A total of 24 special‐status plant species were evaluated for their potential to occur on the project
site, based on their ecology, habitat requirements, and regional occurrences. It was determined,
based on the absence of suitable habitat and/or distance to known occurrences, that all 24 special‐
status plant species were absent from the project site. No special‐status plant species are expected
to occur on‐site, and no further studies are necessary.
Special‐Status Wildlife Species
A total of 23 special‐status wildlife species were evaluated for their potential to occur on the project
site, based on their habitat requirements and regional occurrences. Of the 23 special‐status wildlife
species evaluated, only one species, western mastiff bat (Eumops perotis californicus) has the
potential, albeit low, to occur within the project site due to the presence of marginal roosting habitat
within the vacant building on the project site. Although no roosting was observed during the site
reconnaissance visit, the western mastiff bat is primarily a crevice dwelling species. A number of
roosts in California have been located in appropriately proportioned cracks in buildings (Pierson
1998). In all cases, the bats are in a crevice of at least 10 feet above the ground (Pierson 1998).
Impacts to this species, if found on‐site, would be considered significant. Implementation of
Mitigation Measure (MM) BIO‐1a would reduce potential impacts to the western mastiff bat to a less
than significant level by requiring pre‐construction surveys to avoid disturbing active roosts.
As noted above, there are no trees within the project site, but trees adjacent to the project site have
the potential to provide habitat for nesting birds and raptors protected by the Migratory Bird Treaty
Act (MBTA) and Fish and Game Code Section 3503.5. Construction activity associated with the
project could disrupt nesting birds and raptors. As such, implementation of MM BIO‐1b is required to
reduce potential impacts to migratory and nesting birds and raptors protected under the MBTA to a
less than significant level by requiring preconstruction surveys to be conducted and alteration of
construction activities to avoid disturbance of any active nests. With the implementation of MM BIO‐
1b, impacts to special‐status bird species would be less than significant.
b) Have a substantial adverse effect on any riparian habitat or other sensitive natural community
identified in local or regional plans, policies, and regulations or by the California Department of
Fish and Game or U.S. Fish and Wildlife Service?
No impact. The site is fully developed, consisting of a restaurant and paved parking lot. The project
site does not contain riparian habitat or other sensitive natural communities. Therefore, the project

community. No impact would occur.
c) Have a substantial adverse effect on state or federally protected wetlands (including, but not
limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological
interruption, or other means?
No impact. The site is fully developed, consisting of a restaurant and paved parking lot. The site does
not contain any wetlands or other areas designated as waters of the U.S. or State. Therefore, the
project would not have a substantially adverse effect on State or federally protected wetlands. No
impact would occur.
d) Interfere substantially with the movement of any native resident or migratory fish or wildlife
species or with established native resident or migratory wildlife corridors, or impede the use of
wildlife nursery sites?
Less than significant impact. The project is located in an urban and built‐up area of Santa Ana. The
site is surrounded by development and highly trafficked roads to the north, east, and west, and a
vacant lot to the south. The project site contains impervious surfaces, lacks native vegetation, and is
surrounded by urban development including walls, residential housing, businesses, and busy
roadways. These structures serve as significant barriers to wildlife movement through the project
site and vicinity. As such, the project is not expected to interfere substantially with the movement of
native resident or migratory fish or wildlife species or impede the use of wildlife nursery sites.
Impacts would be less than significant.
e) Conflict with any local policies or ordinances protecting biological resources, such as a tree
preservation policy or ordinance?
No impact. There are several pine trees located in the project vicinity. However, there are no trees
on the project site, and the project would not remove any trees. The City of Santa Ana does not have
a native tree or native shrub protective ordinance and Chapter 33, Article VII, Sections 33–181 of the
City of Santa Ana Municipal Code does not provide specific protection for trees on private property.
As such, the project would not conflict with any local policies or ordinances protecting biological
resources, such as a tree preservation policy or ordinance. No impacts would occur.
f) Conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community
Conservation Plan, or other approved local, regional, or State habitat conservation plan?
No impact. The project does not fall within an adopted Habitat Conservation Plan, regional or local,
and is not subject to the rules or regulations of any other Habitat Conservation Plan or Natural
Community Conservation Plan. As such, no impact would occur.

Mitigation Measures
Roosting Bats
Implementation of the following avoidance and minimization measures would reduce impacts to
roosting bats, specifically to the western mastiff bat.
MM BIO‐1a Prior to demolition, a qualified wildlife biologist will conduct clearance surveys for
special‐status bats concurrently with the nesting birds pre‐construction survey to
confirm there is no roosting on‐site. Survey methodology may include visual surveys of
bats (e.g., observation of bats during foraging period), inspection for suitable habitat,
bat sign (e.g., guano), or use of ultrasonic detectors (Anabat, etc.). Visual surveys will
include the existing vacant structure and trees located on the project site. The type of
survey will depend on the condition of the potential roosting habitat. If no bat roosts
are found, then no further study is required.
If evidence of bat use is observed, the number and species of bats using the roost
will be determined. Bat detectors may be used to supplement survey efforts.
If roosts are determined to be present and must be removed, the bats will be
excluded from the roosting site before the facility is removed. A mitigation program
addressing compensation, exclusion methods, and roost removal procedures will be
developed prior to implementation. Exclusion methods may include the use of one‐
way doors at roost entrances (bats may leave but cannot not reenter), or sealing
roost entrances when the site can be confirmed to contain no bats. Exclusion efforts
may be restricted during periods of sensitive activity (e.g., during hibernation or
while females in maternity colonies are nursing young).
If roosts cannot be avoided or it is determined that construction activities may cause
roost abandonment, such activities may not commence until permanent, elevated bat
houses have been installed outside of, but near to, the construction area. Placement
and height will be determined by a qualified wildlife biologist, but the height of the bat
house will be at least 15 feet. Bat houses will be multi‐chambered and will be
purchased or constructed in accordance with CDFW standards. The number of bat
houses required will be dependent upon the size and number of colonies found, but at
least one bat house will be installed for each pair of bats (if occurring individually), or
of sufficient number to accommodate each colony of bats to be relocated.
Nesting Birds
MM BIO‐1b If construction activity associated with development of the property is to occur
during nesting bird season (February 1 through August 31), a qualified biologist shall
conduct a pre‐construction survey for nesting birds to identify any potential nesting
activity. The pre‐construction surveys for nesting birds shall be conducted within 14
days prior to any construction‐related activities (grading, ground clearing, etc.). If
nesting birds are identified on‐site, a buffer (e.g., 250 feet for raptors, 100 feet for
native songbirds) shall be maintained around the nests; no construction‐related

activities shall be permitted within the buffer. A qualified biologist shall monitor the
nests, and construction activities may commence within the buffer area at the
discretion and in the presence of the biological monitor. This mitigation measure is
not required if construction activities occur outside of the nesting bird season
(September 1 through January 31).

previously conducted cultural resources work as well as identify any previously recorded cultural
resources within a one‐mile radius of the project area. The results of the records search show that 61
resources have been recorded within a 1‐mile radius of the project site, but none are located on the
project site. Of these, 60 resources consist of historic period single‐family residences and various
commercial buildings and one is a prehistoric site. Additionally, at least 36 cultural resources studies
have been conducted within a 1‐mile radius of the project site, none of which included the project site.
A letter was provided by the City dated April 18, 2019 regarding the determination of historical
significance for the building on‐site and is included in Appendix C. The letter states that the subject
building was constructed in 1960 as a drive‐in restaurant. In 1978, an addition was constructed to
the front of the building to increase dining and serving capacity, and in 1981, arches around the
restaurant windows were constructed that significantly altered the physical aesthetics of the
building. Over the years, the restaurant was occupied by multiple business owners and has been
vacant since 2016. The letter concludes that the building is not eligible for inclusion in the California
Register of Historical Resources, nor is it eligible for the Santa Ana registry because the property fails
to meet the California Register Significance Criteria. Thus, the existing building on the project site
does not qualify as a historical resource for the purposes of CEQA.
b) Cause a substantial adverse change in the significance of an archaeological resource pursuant to
Section 15064.5?
Less than significant impact. A Cultural Resources records search for the project area was conducted
on March 11, 2019, and is included as Appendix C. The search was conducted by FCS staff at the
CHRIS SCCIC located at California State University, Fullerton. The search was conducted to identify all
previously conducted cultural resources work as well as identify any previously recorded cultural
resources within a one‐mile radius of the project area. The results of the records search show that
61 resources have been recorded within a 1‐mile radius of the project site, but none are located on
the project site. Of these, 60 resources consist of historic period single‐family residences and various
commercial buildings and one is a prehistoric site. Additionally, at least 36 cultural resources studies
have been conducted within a 1‐mile radius of the project site, none of which included the entire
project site. The project would be subject to compliance with Standard Condition (SC) 2.5‐1, which
provides direction in the event archaeological resources are unearthed during project subsurface
activities. Therefore, project implementation would result in a less than significant impact to
archaeological resources.
c) Disturb any human remains, including those interred outside of formal cemeteries?
Less than significant impact. The past disturbance of the site makes it improbable that construction
of the project would impact human remains, as it is developed with an existing restaurant. No
human remains or cemeteries are known to exist in or near the project area. However, there is
always the possibility that subsurface construction activities associated with the proposed project,
such as trenching and grading, could potentially damage or destroy previously undiscovered human
remains. In the event that human remains are encountered during earth removal or disturbance
activities, California Health and Safety Code Section 7050.5 requires that all activities cease

Heritage Commission. The Native American Heritage Commission would then be required to contact
the most likely descendant of the deceased Native American, who would then serve as consultant
on how to proceed with the remains. Compliance with the established regulatory framework
(California Health and Safety Code Section 7050.5 and Public Resources Code Section 5097.98), as
required by SC 2.5‐3, would reduce potential impacts involving disturbance of human remains to
less than significant.
Tribal Cultural Resources
Would the project cause a substantial adverse change in the significance of a tribal cultural resource,
defined in Public Resources Code Section 21074 as either a site, feature, place, cultural landscape
that is geographically defined in terms of the size and scope of the landscape, sacred place, or object
with cultural value to a California Native American tribe, and that is:
d) Listed or eligible for listing in the California Register of Historical Resources, or in a local register
of historical resources as defined in Public Resources Code Section 5020.1(k), or
No impact. A Cultural Resources records search for the project area was conducted on March 11, 2019,
and is included as Appendix C. The search was conducted by FCS staff at the CHRIS SCCIC located at
California State University, Fullerton. The search was conducted to identify all previously conducted
cultural resources work as well as identify any previously recorded cultural resources within a one‐mile
radius of the project area. The results of the records search show that 61 resources have been
recorded within a 1‐mile radius of the project site, but none are located on the project site. Of these,
60 resources consist of historic period single‐family residences and various commercial buildings and
one is a prehistoric site. Additionally, at least 36 cultural resources studies have been conducted within
a 1‐mile radius of the project site, none of which included the project site.
e) A resource determined by the lead agency, in its discretion and supported by substantial
evidence, to be significant pursuant to criteria set forth in subdivision (c) of Public Resources
Code Section 5024.1. In applying the criteria set forth in subdivision (c) of Public Resource Code
Section 5024.1, the lead agency shall consider the significance of the resource to a California
Native American tribe.

Standard Conditions
SC 2.5‐1 In the event that archaeological resources are encountered during grading and
construction, all construction activities shall be temporarily halted or redirected to
permit the sampling, identification, and evaluation of archaeological materials as
determined by the City, who shall establish with a certified archaeologist, the
appropriate procedures for exploration and/or salvage of the artifacts.
SC 2.5‐2 If human remains are encountered, State Health and Safety Code Section 7050.5
states that no further disturbance shall occur until the County Coroner has made a
determination of origin and disposition pursuant to Public Resources Code Section
5097.98. The County Coroner must be notified of the find immediately. If the
remains are determined to be prehistoric, the Coroner will notify the Native
American Heritage Commission (NAHC), which will determine and notify a Most
Likely Descendant (MLD). With the permission of the landowner or his/her
authorized representative, the MLD may inspect the site of the discovery. The MLD
shall complete the inspection within 24 hours of notification by the NAHC. The MLD
may recommend scientific removal and nondestructive analysis of human remains
and items associated with Native American burials.

Environmental Evaluation
Would the project:
a) Result in potentially significant environmental impact due to wasteful, inefficient, or
unnecessary consumption of energy resources, during project construction or operation?
A significant impact would occur if the project would result in the wasteful, inefficient or
unnecessary use of energy.
Construction
Less than significant impact. During construction, the project would result in energy consumption
through the combustion of fossil fuels in construction vehicles, worker commute vehicles, and
construction equipment, and the use of electricity for temporary buildings, lighting, and other sources.
Fossil fuels used for construction vehicles and other energy‐consuming equipment would be used
during demolition, grading, paving, and building construction. The types of equipment could include
gasoline‐ and diesel‐powered construction and transportation equipment, including trucks, bulldozers,
frontend loaders, forklifts, and cranes. Based on California Emissions Estimator Model (CalEEMod)
estimations within the modeling output files used to estimate greenhouse gas (GHG) emissions
associated with the proposed project, construction‐related vehicle trips would consume an estimated
1,194 gallons of gasoline and diesel combined during the construction phase (Appendix B).
Limitations on idling of vehicles and equipment and requirements that equipment be properly
maintained would result in fuel savings. California regulations limit idling from both on‐road and off‐
road diesel‐powered equipment and are enforced by the ARB (California Code of Regulations [CCR]
Title 13 § 2449(d)(2) and 2485). Also, given the cost of fuel, contractors and owners have a strong
financial incentive to avoid wasteful, inefficient, and unnecessary consumption of energy during
construction.

Other equipment could include construction lighting, field services (office trailers), and electrically
driven equipment such as pumps and other tools. The City’s permissible hours for construction are
7:00 a.m. to 8:00 p.m., Monday through Saturday, except on federal holidays (City of Santa Ana
2018). As on‐site construction activities would be restricted between these hours, it is anticipated
that the use of construction lighting would be minimal. Single‐wide mobile office trailers, which are
commonly used in construction staging areas, generally range in size from 160 square feet to 720
square feet. A typical 720‐square‐foot office trailer would consume approximately 5,318 kilowatt
hours (kWh) during the approximately 7‐month construction phase (Appendix B). Due to the
temporary nature of construction and the financial incentives for developers and contractors to use
energy‐consuming resources in an efficient manner, the construction phase of the proposed project
would not result in wasteful, inefficient, and unnecessary consumption of energy.
Operation
Less than significant impact. The operational phase of the project would consume energy as part of
building operations and transportation activities. Building operations for the project would involve
energy consumption for multiple purposes including, but not limited to, building heating and
cooling, lighting, and electronics, as well as parking lot lighting. Based on CalEEMod estimations
within the modeling output files used to estimate GHG emissions associated with the proposed
project, building operations, including parking lot lighting, would consume approximately 39,318
kWh per year (kWh/year) of electricity, and an estimated 6,580 kilo‐British thermal units per year
(kBTU/year) of natural gas (Appendix B). The total electricity consumption of the City of Santa Ana’s
municipal operations in the year 2008 was 57.7 million kWh (Local Governments for Sustainability
[ICLEI] 2015). Energy consumption of the proposed project represents 0.07 percent of the City’s
2008 municipal electricity consumption. Table 8 shows energy consumption of the proposed
project’s operations relative to the County’s non‐residential, residential, and total energy
consumption.

Operational energy would also be consumed during vehicle trips associated with the project. Fuel
consumption would be primarily related to vehicle use by employees and visitors associated with the
proposed convenience market and gas station. Based on the estimates contained in the CalEEMod
output files, project‐related vehicle trips would result in approximately 1.54 million vehicle miles

traveled, and consume an estimated 63,572 gallons of gasoline and diesel combined on an annual
basis. Complete CalEEMod output files are included in Appendix B. The project is located within 3
miles of multiple interchanges for Interstate 5 and State Route 22. As such, it would be in proximity
to two regional routes of travel, thus further reducing fuel consumption demand. The First and Raitt
Orange County Transit Authority (OCTA) 64Xpress bus stop is located 0.1 mile east of the project site,
offering a nearby option for public transportation to and from the site. For these reasons,
transportation fuel consumption would not be wasteful, inefficient, or unnecessary.
The proposed project’s building would be designed and constructed in accordance with the State’s
Title 24 energy efficiency standards. These standards, widely regarded as the most advanced energy
efficiency standards, would help reduce the amount of energy required for lighting, water heating,
and heating and air conditioning in buildings and promote energy conservation. The City of Santa
Ana further supports energy conservation through policies, programs, and measures contained
within the Energy Element of its General Plan (City of Santa Ana 1982) and the Santa Ana Climate
Action Plan (ICLEI 2015). Both of these plans reinforce energy performance requirements, in
accordance with the State’s building code standard. The City’s General Plan and Climate Action Plan
also include voluntary policies, programs, and measures to promote energy conservation and the
reduction of non‐renewable energy consumption. One such measure encourages solar power and
solar heat fixtures for businesses, and would offer rebates or incentive payments for installation of
solar PV. Another measure helps small businesses identify ways to save electricity through free
upgrades to energy efficient lighting, signage, sensors, refrigeration, sun‐block window film, and
programmable thermostats. The Green Business Challenge Program is a voluntary measure that
establishes friendly competition between businesses to improve performance in energy efficiency,
water conservation, waste reduction, and other areas, in which businesses receive recognition for
participating, and the City recognizes those that achieve the largest GHG emissions reduction. These
voluntary measures at the City level further support the required State standards, which ensure that
the proposed project would not result in an inefficient, wasteful, or unnecessary use of energy.
Operational energy impacts would be less than significant.
b) Conflict with or obstruct a State or local plan for renewable energy or energy efficiency?
A significant impact would occur if the project would conflict with or obstruct a State or local plan for
renewable energy or energy efficiency.
Construction
Less than significant impact. As described above, the project would result in energy consumption
through the combustion of fossil fuels in construction vehicles, worker commute vehicles, and
construction equipment, and the use of electricity for temporary buildings, lighting, and other
sources. The types of equipment could include gasoline‐ and diesel‐powered construction and
transportation equipment, including trucks, bulldozers, frontend loaders, forklifts, and cranes. Other
equipment could include construction lighting, field services (office trailers), and electrically driven
equipment such as pumps and other tools.

California regulations (CCR Title 13 § 2449(d)(3) and 2485) limit idling from both on‐road and off‐
road diesel‐powered equipment. The project would be required to comply with these regulations,
which are enforced by the ARB. Part 11, Chapter 5, of the State’s Title 24 energy efficiency standards
establish mandatory measures for non‐residential buildings, including material conservation and
efficiency. The project would also be required to comply with these mandatory measures. In the
Energy Element of the City’s General Plan, Objective 1.2 promotes reduction in construction‐related
energy consumption. The project would not conflict with or obstruct this voluntary objective.
Therefore, it is anticipated that the construction phase of the project would not conflict with or
obstruct state or local plans for renewable energy or energy efficiency. Construction‐related energy
impacts would be less than significant.
Operation
Less than significant impact. The operational phase of the project would consume energy as part of
building operations and transportation activities. Building operations for the project would involve
energy consumption for multiple purposes including, but not limited to, building heating and
cooling, lighting, and electronics, as well as parking lot lighting. The State’s Title 24 energy efficiency
standards are widely regarded as the most advanced energy efficiency standards. These standards
help reduce the amount of energy required for lighting, water heating, and heating and air
conditioning in buildings and promote energy conservation. The project would be required to
comply with these standards.
At the local level, the Energy Element of the City’s General Plan contains goals to reduce
consumption of non‐renewable energy and to support development and utilization of new energy
sources. Page 14 of the Energy Element includes a policy to establish, update, and/or enforce energy
performance requirements in the building code, in accordance with the State’s building code
standard. The Santa Ana Climate Action Plan establishes the City’s energy savings goals as follows: 70
million kWh/year by 2020, from 2008 baseline community usage, and 100 million kWh/year by 2035.
The Santa Ana Climate Action Plan contains a measure that supports the State mandated Title 24
Energy Efficiency Standard, enforced locally by the City of Santa Ana through the building permit
review and inspection process. As noted in Section 6c, the City’s General Plan and Climate Action
Plan contain multiple voluntary measures supporting renewable energy and energy efficiency. The
proposed project would not conflict with or obstruct any of these local voluntary measures.
California’s Renewables Portfolio Standard (RPS) requires that 33 percent of electricity retail sales be
served by renewable energy sources by 2020. The proposed project would be served with gas
provided by Southern California Gas (SoCalGas). SoCalGas offers renewable natural gas captured
from sources like dairies, wastewater treatment plants and landfills (SCG 2019). The proposed
project would be served with electricity provided by Southern California Edison (SCE). SCE’s 2017
power mix included 32 percent eligible renewable (biomass and biowaste, geothermal, eligible
hydroelectric, solar, and wind), 34 percent unspecified sources of power, 20 percent natural gas, 8
percent large hydroelectric, and 6 percent nuclear (SCE 2018). SCE also offers a Green Rate 50
percent option that sources 66 percent of its power mix from eligible renewable energy sources, and

a Green Rate 100 percent option that sources 100 percent of its power mix from eligible renewable
energy sources. SCE is on track to meet California’s RPS of 33 percent by 2020 mandate (SCE 2019).
The proposed project would not conflict with or obstruct a state or local plan for renewable energy
or energy efficiency. Operational energy impacts would be less than significant.

The following section is based on information contained within the Geotechnical Investigation
Report prepared by Stantec Consulting Services Inc. on February 2, 2018, which is included as
Appendix D. The Geotechnical Investigation Report summarizes the results of a field exploration,

laboratory testing and engineering and geologic analyses that were conducted for the proposed
project. The Geotechnical Investigation Report is included in Appendix D of this report.
Would the project:
a) Directly or indirectly cause potential substantial adverse effects, including the risk of loss, injury
or death involving:
i) Rupture of a known earthquake fault, as delineated on the most recent Alquist‐Priolo
Earthquake Fault Zoning Map issued by the State Geologist for the area or based on other
substantial evidence of a known fault? Refer to Division of Mines and Geology Special
Publication 42.
Less than significant impact. Seismically induced surface rupture is defined as the physical
displacement of surface deposits in response to an earthquake’s seismic waves. Surface rupture is
most likely along active faults, and typically occurs during earthquakes of magnitude five or higher.
Not all earthquakes result in surface rupture (DOC 2019).
The Alquist‐Priolo Earthquake Fault Zoning Act was passed in 1972 to mitigate the hazard of surface
faulting to structures for human occupancy. The Act’s main purpose is to prevent the construction of
buildings used for human occupancy on the surface trace of active faults. The Act requires the State
Geologist to establish regulatory zones, known as “Alquist‐Priolo (AP) Earthquake Fault Zones,”
around the surface traces of active faults and to issue appropriate maps. If an active fault is found, a
structure for human occupancy cannot be placed over the trace of the fault and must be set back
from the fault (typically 50 feet).
Based on the “Fault Rupture Hazard Zones in California, Special Publication 42, Interim Revision
2018,” published by the State of California Conservation Department, and the Geotechnical
Investigation Report prepared for the project, the site is not located within an identified Alquist‐
Priolo Earthquake Hazard Zone (Stantec 2018).
According to the City of Santa Ana’s General Plan Land Use Element, there are no known fault traces
located in the City of Santa Ana (City of Santa Ana 1998). Furthermore, the February 2018
Geotechnical Investigation Report states that there are no known active faults that underlie or are
located in the project site. The closest known faults are the San Joaquin Hills Fault and the Newport
Inglewood Fault zone, located approximately 3.6 miles south and 7.4 miles southwest of the project
site, respectively. Therefore, the probability of surface fault rupture occurring form an active fault is
considered low. Additionally, the project would be required to follow seismic design parameters
based upon the 2016 California Building Code (CBC). As such, impacts are considered less than
significant.
ii) Strong seismic ground shaking?
Less than significant impact with mitigation incorporated. Seismic ground shaking is influenced by
the proximity of the site to an earthquake fault, the intensity of the seismic event, and the
City of Santa Ana Environmental Checklist and 7‐Eleven Convenience Store and Service Station Project Environmental Evaluation Initial Study/Mitigated Negative Declaration
52 FirstCarbon Solutions
Y:\Publications\Client (PN‐JN)\0327\03270041\ISMND\03270041 City of Santa Ana 7‐Eleven Store ISMND.docx
underlying soil composition. A geologic hazard likely to affect the project is ground‐shaking as a
result of movement along an active fault zone in the vicinity of the subject site. However, given that
the site is not located on an earthquake fault, the risk from ground shaking would be less than
significant with the implementation of seismic design requirements of the 2016 CBC. Furthermore,
recommendations from the February 2018 Geotechnical Investigation Report are included as MM
GEO‐1 through MM GEO‐7. Compliance with 2016 CBC and implementation of MM GEO‐1 through
MM GEO‐7 would reduce impacts to a less than significant level.
iii) Seismic‐related ground failure, including liquefaction?
Less than significant impact with mitigation incorporated. Liquefaction is a mode of ground failure
that results from the generation of high water pressures during earthquake ground shaking, causing
loss of shear strength. Liquefaction is typically a hazard where loose sandy soils exist below
groundwater. The California Geologic Survey (CGS) has designated certain areas within Southern
California as potential liquefaction hazard zones. These are areas considered at a risk of liquefaction‐
related ground failure during a seismic event, based upon mapped surficial deposits and the
presence of a relatively shallow water table (USGS 2016).
The project site is located in a CGS Liquefaction Hazard Zone (Division of Mines and Geology [CDMG]
1997). This zone is defined as areas where historical occurrence of liquefaction, or local geological,
geotechnical, and groundwater conditions indicate a potential for permanent ground displacements
such that mitigation would be required.
According to the City of Santa Ana General Plan Land Use Element, the areas of the City that are
susceptible to liquefaction are in close proximity to the Santa Ana River (City of Santa Ana 1998). The
project area is approximately 0.88 mile from the Santa Ana River and is classified as “low” probability
for liquefaction according to Exhibit A‐7, Liquefaction, of the City’s General Plan Land Use Element.
Furthermore, according to the Geotechnical Investigation Report, the liquefaction and lateral spread
potential at the site is considered low. However, the unsaturated, medium dense sand may densify as a
result of earthquake shaking, causing ground surface settlement. Ground surface total settlements due
to compression in the unsaturated zone are estimated to be on the order of 0.5‐inch. Differential
settlement over a span of approximately 30 feet is estimated to be approximately 0.25‐inch. Based on
the relatively low estimated liquefaction induced settlement, conventional shallow foundations appear
to be a suitable option for support of the proposed buildings. MM GEO‐1 through MM GEO‐3 identify
the minimum criteria based on geotechnical considerations. Thus, with implementation of MM GEO‐1
to MM GEO‐3, impacts regarding liquefaction would be less than significant.
iv) Landslides?
Less than significant impact. As discussed in the Geotechnical Investigation Report, the project site
is located in a relatively flat valley and there are no historic landslides mapped at the site. Evidence
of landslides or slope instabilities was not observed in the project vicinity during site activities.
Accordingly, the potential for landslides or slope instabilities to occur at the site is low. Furthermore,
according to the City of Santa Ana’s General Plan Land Use Element, there is the potential for slope

failure and landslides to occur near the banks of the Santa Ana River or Santiago Creek; however,
these areas are approximately 0.88 and 1.74 miles west, respectively, of the project site (City of
Santa Ana 1998). As such, there would be less than significant impacts related to landslides on the
project site.
b) Result in substantial soil erosion or the loss of topsoil?
No impact. The project site is urban and developed, with cement and asphalt paving covering all soil
and topsoil. According to the City of Santa Ana’s General Plan Land Use Element, soil and topsoil
erosion is associated mainly with soils along the Santa Ana River and Santiago Creek (City of Santa
Ana 1998). The project is located approximately 0.88 mile from the Santa Ana River and 1.74 miles
from Santiago Creek. As such, there would be no impact.
c) Be located on a geologic unit or soil that is unstable, or that would become unstable as a result
of the project, and potentially result in on‐ or off‐site landslide, lateral spreading, subsidence,
liquefaction or collapse?
Less than significant impact with mitigation incorporated. The following analysis is based on the
City of Santa Ana’s General Plan Land Use Element and the February 2018 Geotechnical Investigation
Report:
Liquefaction or Collapse: The soil conditions at the site are considered to have low
susceptibility to liquefaction, according to Exhibit A‐7 of the General Plan.
Lateral Spreading: As discussed in the response to liquefaction (see above) the site is located
in a “low” liquefaction hazard area, in a relatively flat urbanized area, and is not in the vicinity
of slopes that would be susceptible to liquefaction (slope areas that have sufficient height,
slope ratio, and underlying geologic conditions that can result in liquefaction. The project‐
specific Geotechnical Investigation Report identified the unsaturated, medium dense sand on
the project site may densify as a result of earthquake shaking, causing ground surface
settlement. Therefore, implementation of MM GEO‐1 to MM GEO‐7 would reduce impacts of
earthquake‐induced lateral spreading to less than significant.
Landslide: The site is not located within a designated area where previous occurrence of
landslide movement, or local topographic, geological, geotechnical and subsurface water
conditions occurred. The site is flat and is not located near slopes that would be susceptible to
landslides. Impacts from landslides would be less than significant.
Subsidence: According to the City of Santa Ana General Plan Land Use Element, the soils near
the Santa Ana River may be subject to subsidence. The project is 0.88 mile from the Santa Ana
River, and Exhibit A‐8 of the General Plan shows that the project site is outside of the
subsidence boundary.
Furthermore, according to the Geotechnical Investigation Report, the liquefaction and lateral spread
potential at the site is considered low. However, the unsaturated, medium dense sand may densify
as a result of earthquake shaking, causing ground surface settlement. Ground surface total

settlements due to compression in the unsaturated zone are estimated to be on the order of 0.5‐
inch. Differential settlement over a span of approximately 30 feet is estimated to be approximately
0.25‐inch. Based on the relatively low estimated liquefaction induced settlement, conventional
shallow foundations appear to be a suitable option for support of the proposed buildings. MM GEO‐
1 through MM GEO‐3 identify the minimum criteria based on geotechnical considerations. Thus,
with implementation of MM GEO‐1 through MM GEO‐3, impacts regarding unstable soils, lateral
spreading, subsidence, liquefaction or collapse would be reduced to less than significant.
d) Be located on expansive soil, as defined in Table 18‐1‐B of the Uniform Building Code (1994),
creating substantial direct or indirect risks to life or property?
Less than significant impact. The City of Santa Ana General Plan Land Use Element describes the
soils susceptible to expansion as the Omni and Thapto soils located in the south central section of
the City south of Segerstrom Avenue (City of Santa Ana 1998). The boundary of this area is located
2.51 miles south of the project site.
The near‐surface soils (upper approximate 10 feet) have a very low expansion potential according to
the Geotechnical Investigation Report. Impacts would be less than significant.
e) Have soils incapable of adequately supporting the use of septic tanks or alternative wastewater
disposal systems where sewers are not available for the disposal of wastewater?
No impact. The project does not propose the use of septic tanks. The project would connect to the
City sanitary sewer system through existing lines for wastewater disposal. Therefore, no impacts to
soils due to the use of septic systems would occur.
f) Directly or indirectly destroy a unique paleontological resource or site or unique geologic
feature?
Less than significant impact. A paleontological records search was conducted by staff at the Los
Angeles County Museum of Natural History on March 12, 2019. The report indicates that surface
sediments encountered beneath fill materials on the project site consist of younger terrestrial
Quaternary Alluvium, derived primarily from the hills to the northeast of the project. These shallow
sediments typically do not produce significant vertebrate fossils. However, older Quaternary
sediments are present at depths of 8 feet or more and have yielded significant vertebrate fossils in
the vicinity of the project. Therefore, development activities have the potential to encounter
undiscovered paleontological resources and the project would be subject to compliance with SC 2.5‐
1, which provides direction in the event paleontological resources are unearthed during project
subsurface activities. Therefore, project implementation would result in a less than significant
impact involving the potential destruction of a paleontological resource.

Grading shall conform to the guidelines presented in the 2016 CBC, as well as the
requirements of the City of Santa Ana and Orange County.
Building Pad Foundation Areas: All undocumented fill shall be removed from below
the proposed building footprint, if encountered. The removal of soil fill shall extend
at least 5 feet beyond the building perimeter unless constrained by existing
structures or improvements. The removals shall extend to a depth of at least 3 feet
below the bottom of the lowest foundation. The removal depth below the building
footprint shall be relatively level to provide a uniform compacted fill mat.
The bottom of the remedial grading excavations shall be scarified to a depth of 8‐
inches, moisture conditioned to within 0 to 4 percentage points above the
optimum moisture content and compacted to at least 95 percent relative
compaction based on the ASTM D1557 laboratory test procedure. All references
to optimum moisture content and relative compaction in this report are based on
this test method.
Pavement and Hardscape: Remedial grading for pavement and hardscape areas
shall include removal of the existing soils to a depth of at least 2 feet below the
existing ground surface or subgrade elevation, whichever is lower. The soil
exposed at the base of the excavation shall be scarified to a depth of 8 inches, and
moisture conditioned to within 0 to 4 percentage points above the optimum
moisture content. Hardscape subgrade shall be compacted to at least 90 percent
relative compaction. Pavement subgrade shall be compacted to at least 95
percent relative compaction.
Field Observation: The Geotechnical Engineer shall check the bottom of
excavations. If soft, loose, wet, or otherwise unsuitable soils are encountered, the
depth of removal may be extended, or additional recommendations can be
provided.
Fill Placement and Compaction: Excavated materials determined by the
Geotechnical Engineer to be satisfactory can be reused as compacted fill. With the
exception of the asphalt and concrete, it is anticipated that the majority of the
excavated materials can be re‐used as compacted fill soils. The asphalt grinding’s
may be reused in non‐building areas provided they are broken down to less 3
inches and thoroughly mixed with other materials. The existing concrete

pavement on the site may be reused within the compacted fill provided all debris
such as rebar is removed and the concrete is broken down or crushed to a
maximum 3‐inch size. The concrete pieces shall be thoroughly mixed with finer
soil such that nesting of coarse fragments which could result in voids does not
occur. The Geotechnical Engineer shall approve the fill material before placement.
‐ Fill shall be placed in 6‐ to 8‐inch thick loose, horizontal lifts, moisture
conditioned to within 0 to 4 percentage points above the optimum moisture
content, and compacted to at least 95 percent relative compaction. The
maximum dry density and optimum moisture content for the evaluation of
relative compaction shall be determined in accordance with ASTM D1557.
‐ Fill material with high fines contents will be difficult to compact in wet weather
conditions. Accordingly, during wet weather conditions, the use of
predominately granular fill material with less than 5 percent passing the #100
sieve is recommended.
Pipelines: Typical pipe bedding as specified in the Standard Specifications for
Public Works Construction (GREENBOOK) may be used. As a minimum, it is
recommended that pipe be supported on at least 4 inches of granular bedding
material, such as 0.75‐inch rock or clean coarse sand with less than 5 percent
fines and a sand equivalent of 40 or more as evaluated by ASTM D2419.
‐ The bedding shall extend from the bottom of the trench to at least 1 foot above
the top of the pipe. Sand bedding shall be mechanically compacted to at least
90 percent relative compaction. Jetting of sand bedding shall not be permitted.
‐ On‐site material, imported select material, or 2‐sack cement/sand slurry may be
used as backfill in trenches above the pipe bedding. The material selected shall
match the engineering characteristics of the soils adjacent to the trench. Utility
trench backfill beneath structures and hardscape shall be compacted to at least
90 percent relative compaction.
‐ The modulus of soil reaction (E’) is used to characterize the stiffness of soil
backfill placed along the sides of buried flexible pipelines. For the purpose of
evaluating deflection due to the load associated with trench backfill over the
pipe, a value of 1,500 pounds per square inch (lbs/in2) is recommended for the
general site conditions assuming granular bedding material (sand or gravel) is
placed adjacent to the pipe.
Imported Material: Imported materials, if used for fill, shall be predominately
granular, contain no rocks or lumps greater than 3 inches in maximum dimension,
and have a Plasticity Index less than 15. Imported materials shall be reviewed and
approved by the Geotechnical Engineer before being brought to the site.
Oversized Material: Excavations may generate oversized material. Oversized
material is defined as rocks or cemented clasts greater than 3 inches in largest
dimension. Oversized material shall be broken down to no greater than 3 inches in
largest dimension for use in fill.
Temporary Excavations: The existing fill soils can be considered Type B for
excavation in accordance with Occupational Safety and Health Administration

(OSHA) and California Occupational Safety and Health Administration (Cal/OSHA)
requirements. Temporary excavations shall be shored or excavated with a slope
not steeper than 1.5:1 (horizontal to vertical) in accordance with OSHA and
Cal/OSHA requirements.
‐ The excavations shall be inspected daily by the contractor’s Competent Person
before personnel are allowed to enter the excavation. Any zones of potential
instability, sloughing or raveling shall be brought to the attention of the
Geotechnical Engineer and corrective action implemented before personnel
begin working in the excavation. Excavated soils shall not be stockpiled behind
temporary excavations within a distance equal to the depth of the excavation.
‐ A Geotechnical Engineer shall be notified if other surcharge loads are anticipated so that lateral load criteria can be developed for the specific
situation. If temporary slopes are to be maintained during the rainy season,
berms are recommended near the tops of slopes to prevent runoff water from
entering the excavation and eroding the slope faces.
Braced Shoring System: For braced shoring above the groundwater level, a
uniform rectangular pressure distribution shall be used from top to bottom of the
shoring equivalent to the following, Bracing: 30H pounds per square foot
(psf)/feet where H is the depth of the excavation, in feet. The earth pressures
indicated above do not include a safety factor; therefore, the shoring design shall
include an appropriate safety factor for the overall performance of the system.
Surface Drainage: Final surface grades around structures shall be designed to
collect and direct surface water away from the structure and toward appropriate
drainage facilities. The ground around the structure shall be graded so that
surface water flows rapidly away from the structure without ponding. In general,
we recommend that the ground adjacent to the structure slope away at a gradient
of at least 2 percent. Densely vegetated areas where runoff can be impaired shall
have a minimum gradient of at least 5 percent within the first 5 feet from the
structure. Roof gutters with downspouts that discharge directly into a closed
drainage system are recommended on structures. Drainage patterns established
at the time of fine grading shall be maintained throughout the life of the proposed
structures. Site irrigation shall be limited to the minimum necessary to sustain
landscape growth. Shall excessive irrigation, impaired drainage, or unusually high
rainfall occur, saturated zones of perched groundwater can develop.
Grading Plan Review: A Geotechnical Engineer shall review the grading plans and
earthwork specifications to ascertain whether the intent of the recommendations
contained in this report have been implemented, and that no revised
recommendations are needed due to changes in the development scheme.

MM GEO‐2 Conventional Shallow Foundations
An allowable bearing pressure of 2,500 psf shall be used for conventional square or rectangular shallow foundations founded in properly compacted fill. The
bearing capacity can be increased by one third for transient loading conditions
such as earthquake and wind.
Additional parameters for shallow foundations are provided below.
Minimum Footing Width: 18 inches for continuous footings 24 inches for
square/rectangular footings
Minimum Footing Depth: 18 inches below lowest adjacent soil grade
Minimum Reinforcement: Two No. 5 bars at both top and bottom in
continuous footings.
Canopy Foundations: Typical shallow drilled pier footings for the canopy columns are
expected to provide adequate support for the proposed structures provided that the
recommendations provided herein are incorporated in the design. We understand
that typical canopy column footings will consist of reinforced concrete drilled piers
having a minimum diameter or width of 4 feet and embedded a minimum depth of 7
feet bgs. Based on these assumptions and the anticipated subsurface conditions, an
allowable bearing pressure of 4,000 psf may be used in the design. For resistance to
transient lateral loads, such as earthquake and wind loads, the aforementioned
allowable bearing capacity may be increased by one‐third.
Lateral Resistance: Lateral loads will be resisted by friction between the bottoms
of footings and passive pressure on the faces of footings and other structural
elements below grade. An allowable coefficient of friction of 0.30 can be used.
Passive pressure can be computed using an allowable lateral pressure of 300 psf
per foot of depth below the ground surface for level ground conditions.
Reductions for sloping ground shall be made. The passive pressure can be
increased by one‐third when considering the total of all loads, including wind or
seismic forces. The upper 1 foot of soil shall not be relied on for passive support
unless the ground is covered with pavements or slabs.
Foundation Plan Review: A Geotechnical Engineer shall review the foundation
plans to ascertain that the intent of the recommendations in this report has been
implemented and that revised recommendations are not necessary as a result of
changes after this report was completed.
Foundation Excavation Observations: A representative working under direct
supervision of the Geotechnical Engineer shall observe the foundation excavations
prior to forming or placing reinforcing steel.
MM GEO‐3 Slabs‐On‐Grade
Interior Slabs on Grade: The top 24 inches of material below interior concrete
slabs‐on‐grade shall have an expansion index of 20 or less. The project structural

engineer shall design the interior concrete slabs‐on‐grade floor. However, we
recommend a minimum thickness of 5 inches.
‐ A vapor barrier shall be placed beneath slabs where moisture sensitive floor
coverings will be installed. If plastic is used, a minimum 10‐mil is recommended.
The plastic shall comply with ASTM E1745. Installation shall comply with ASTM
E1643. Current construction practice typically includes placement of a 2‐inch
thick sand cushion between the bottom of the concrete slab and the moisture
vapor retarder/barrier. This cushion can provide some protection to the vapor
retarder/barrier during construction, and may assist in reducing the potential
for edge curling in the slab during curing. However, the sand layer also provides
a source of moisture to the underside of the slab that can increase the time
required to reduce vapor emissions to limits acceptable for the type of floor
covering placed on top of the slab. The slab can be placed directly on the vapor
retarder/barrier. The floor covering manufacturer shall be contacted to
determine the volume of moisture vapor allowable and any treatment needed
to reduce moisture vapor emissions to acceptable limits for the particular type
of floor covering installed. The project team shall determine the appropriate
treatment for the specific application.
‐ In addition to the moisture vapor barrier, a capillary moisture break shall be
constructed below the slab to further reduce moisture transmission from the
subgrade soil, if desired. The capillary moisture break shall consist of at least 4‐
inches of clean, free‐draining gravel or crushed rock placed below the moisture
vapor retarder/barrier. The components of the capillary moisture break shall meet
the particle‐size gradation presented in Table 3 of the Geotechnical Report.
‐ Exterior Slab on Grade: The top 24 inches of material below exterior concrete
slabs‐on‐grade shall have an expansion index of 20 or less determined in
accordance with ASTM D4829 or a Plasticity Index less than 15. Exterior slabs shall
have a minimum thickness of 4 inches and be reinforced with at least No. 4 bars
at 18 inches on center each way. Slabs shall be provided with weakened plane
joints. Joints shall be placed in accordance with the American Concrete Institute
(ACI) guidelines. The project architect shall select the final joint patterns.
MM GEO‐4 Underground Storage Tank Backfill
Backfilling adjacent to and over the top of the underground storage tanks shall be performed in accordance with the tank manufacturer’s specifications. Pea gravel
used for tank backfill shall be encapsulated (“burrito wrapped”) in a geotextile fabric
to prevent migration of fines into the voids within the pea gravel, which could cause
ground settlement. The pea gravel backfill shall be covered with a structural
concrete slab designed to bridge over localized settlement of the gravel backfill.
‐ Depending on the actual quality and composition of the gravel utilized to
backfill the USTs, little or no mechanical compactive effort is generally necessary
to place the gravel in a dense manner.

‐ However, to increase the density of the gravel backfill and to mitigate future
settlement of the gravel backfill the following methods shall be utilized. The
gravel shall be compacted with a concrete vibrator or mechanical compaction
equipment, at approximate 2 to 3 foot intervals.
MM GEO‐5 Pavement
Asphalt Concrete Pavement: An R‐Value of 9 has been assumed for preliminary
design of pavement sections based on laboratory test results and visual
observation of the on‐site material in the upper 5 feet. The actual R‐value of the
subgrade soils shall be determined after grading to provide final pavement design.
Flexible pavement sections have been calculated in general conformance with
Caltrans guidelines. The project civil engineer and owner shall review the
pavement designations to determine appropriate locations for pavement
thickness. Based on an assumed R‐value of 9, the following pavement structural
sections have been calculated (See Table 4 of the Geotechnical Report.
‐ Prior to placing base materials, the upper 12 inches of the subgrade soil shall be
scarified, moisture conditioned to slightly above the optimum moisture content,
and recompacted to a dry density of at least 95 percent of the laboratory
maximum. The base material shall also be compacted to slightly above the
optimum moisture content and a dry density of at least 95 percent of the
laboratory maximum.
‐ Rigid concrete pavement (described below) shall be placed in driveway entrance
aprons and trash bin loading/storage areas. Concrete pavement design is
provided in the following section.
Concrete Pavement: Concrete pavements have been calculated in general
conformance with the procedure recommended by the ACI (ACI 330R‐08) using
the parameters presented in the table below. The following design parameters
were used in our analyses. See Table 6 of the Geotechnical Report for
recommended concrete pavement sections.
‐ The project civil engineer shall confirm whether the assumed Average Annual
Daily Traffic (AADT) is appropriate for the anticipated traffic level. Concrete
compressive strength for pavement should be at least 3,700 psi. Rigid concrete
pavement shall be placed in driveway entrance aprons, trash bin
loading/storage areas, or other areas of the project site as desired. Crack control
joints shall be placed in accordance with the ACI guidelines. Minimum
reinforcement shall consist of #3 bars on 24‐inch centers.
‐ Prior to placing concrete, the upper 12 inches of the subgrade soil shall be scarified, moisture conditioned to slightly above the optimum moisture content,
and recompacted to a dry density of at least 95 percent of the laboratory
maximum.

Environmental Evaluation
Greenhouse Gas Emissions
Would the project:
a) Generate greenhouse gas emissions, either directly or indirectly, that may have a significant
impact on the environment?
Less than significant Impact. Gases that trap heat in the atmosphere are referred to as greenhouse
gases (GHG). The effect is analogous to the way a greenhouse retains heat. Prominent GHGs that
naturally occur in the Earth’s atmosphere are water vapor, carbon dioxide (CO2), methane (CH4),
oxides of nitrogen (NOX), and ozone. There have been significant legislative and regulatory activities
that directly and indirectly affect climate change and GHGs in California. The primary climate change
legislation in California is Assembly Bill (AB) 32, the California Global Warming Solutions Act of 2006,
focusing on reducing GHG emissions in California. The proposed project would generate a variety of
GHG emissions during construction and operation, including several defined by AB 32 such as CO2,
CH4, and nitrous oxide.
To describe how much global warming a given type and amount of GHG may cause, the CO2 equivalent
(CO2e) is used. The calculation of the CO2 equivalent is a consistent methodology for comparing GHG
emissions since it normalizes various GHG emissions to a consistent reference gas, CO2. For example,
CH4’s warming potential of 25 indicates that CH4 has 25 times greater warming effect than CO2 on a
molecule‐per‐molecule basis. A CO2 equivalent is the mass emissions of an individual GHG multiplied
by its global warming potential. Both construction period and operational period activities have the
potential to generate GHG emissions.
The project would generate GHG emissions during temporary (short‐term) construction activities
such as site grading, construction equipment engines, on‐site heavy‐duty construction vehicles,
vehicles hauling materials to and from the project site, asphalt paving, and motor vehicles used by

the construction workers. On‐site construction activities would vary depending on the level of
construction activity.
Long‐term, operational GHG emissions would result from project generated vehicular traffic, on‐site
combustion of natural gas, operation of any landscaping equipment, off‐site generation of electrical
power over the life of the project, the energy required to convey water to and wastewater from the
project site, the emissions associated with the hauling and disposal of solid waste from the project
site, and any fugitive refrigerants from air conditioning or refrigerators.
The SCAQMD developed interim recommended significance thresholds for GHGs for local lead
agency consideration (SCAQMD draft local agency threshold) in 2008; however, the SCAQMD Board
has not approved the thresholds as of the date of this analysis. The current interim thresholds
consist of the following tiered approach:
Tier 1 consists of evaluating whether or not the project qualifies for any applicable exemption
under CEQA.
Tier 2 consists of determining whether the project is consistent with a GHG reduction plan. If a
project is consistent with a qualifying local GHG reduction plan, it does not have significant
GHG emissions.
Tier 3 consists of screening values, which the lead agency can choose, but must be consistent
with all projects within its jurisdiction. A project’s construction emissions are averaged over 30
years and are added to a project’s operational emissions. If a project’s emissions are under
one of the following screening thresholds, then the project is less than significant:
‐ All land use types: 3,000 metric tons (MT) CO2e per year
‐ Based on land use type: residential: 3,500 MT CO2e per year; commercial: 1,400 MT CO2e
per year; industrial: 10,000 MT CO2e; or mixed use: 3,000 MT CO2e per year
Tier 4 has the following options: ‐ Option 1: Reduce emissions from BAU by a certain percentage; this percentage is currently
undefined
‐ Option 2: Early implementation of applicable AB 32 Scoping Plan measures
‐ Option 3, 2020 target for service populations (SP), which includes residents and employees:
4.8 MT CO2e/SP/year for projects and 6.6 MT CO2e/SP/year for plans;
‐ Option 4, 2035 target: 3.0 MT CO2e/SP/year for projects and 4.1 MT CO2e/SP/year for plans
Tier 5 involves mitigation offsets to achieve target significance threshold.
To determine whether the proposed project would have a significant impact with respect to the
generation of GHG emissions, this analysis utilizes the SCAQMD’s draft local agency Tier 3 threshold
of 3,000 MT CO2e per year for all land use types.
Construction GHG Emissions
SCAQMD recommends that construction‐related GHG emissions be amortized over the life of the
project, which is defined as 30 years, and added to annual operational emissions. Construction‐

related GHG emissions were modeled using the same assumptions and model (CalEEMod Version
2016.3.2) as those for air quality emissions. Construction‐related GHG emissions would occur from
fossil fuel combustion for heavy‐duty construction equipment, material delivery and haul trucks, and
construction worker vehicles. Table 9 presents the project’s total construction‐related GHG
emissions and amortized construction emissions.
As shown in Table 9, construction of the project is estimated to generate approximately 93 MT CO2e
over the entire project construction duration. Amortized emissions would equal to 3 MT CO2e per
year.

Operational GHG Emissions
Operational or long‐term emissions occur over the life of the project. The major sources for
operational GHG emissions include:
Motor Vehicles: These emissions refer to GHG emissions contained in the exhaust from the
cars and trucks that would travel to and from the project site. Trip generation rates used in
estimating mobile‐source emissions were consistent with those presented in traffic site
analysis prepared for the project by RK Engineering Group (RKEG 2018).
Natural Gas: These emissions refer to the GHG emissions that occur when natural gas is
burned on the project site. Natural gas uses could include heating water, space heating,
stoves, or other uses.
Indirect Electricity: These emissions refer to those generated by off‐site power plants to
supply electricity required for the project. All electricity at the project site would be supplied
by SCE.

FirstCarbon Solutions 65 Y:\Publications\Client (PN‐JN)\0327\03270041\ISMND\03270041 City of Santa Ana 7‐Eleven Store ISMND.docx
Water Transport: These emissions refer to those generated by the electricity required to
transport and treat the water to be used on the project site.
Waste: These emissions refer to the GHG emissions produced by decomposing waste
generated by the project.
Project Operations
Operational GHG emissions for both 2020 and 2030 are shown in Table 10. At project buildout
(2020), the project is estimated to generate 744 MT CO2e. In 2030, total GHG emissions are estimated
at 583 MT CO2e. Table 10 presents the project’s annual operational emissions along with the
amortized construction emissions. Pursuant to SCAQMD’s guidance, the sum of these emissions
should be used to compare with the applicable threshold of significance.

waste GHG emissions are based on the Convenience Market (24 Hour) land use of an equivalent square footage.
MTCO2e = metric tons of carbon dioxide equivalent Source of emissions: CalEEMod Output (see Appendix A). Source of thresholds: SCAQMD 2008c.
As shown in Table 10, the project would not exceed the applicable SCAQMD 3,000 MT CO2e threshold.
Therefore, the project would not generate GHG emissions that may have a significant impact on the
environment.
b) Conflict with any applicable plan, policy or regulation adopted for the purpose of reducing the
emissions of greenhouse gases?
Less than significant impact. The City of Santa Ana adopted a Climate Action Plan (CAP) in December
2015 with the goal of reducing carbon emissions and energy use for the community. The CAP
includes reduction measures that would help the City achieve their emissions reduction goal of 15

percent by 2035. These reduction measures address emissions in five sectors: transportation and
land use, energy, solid waste, water, and wastewater. Project consistency with the applicable
reduction measures specified in the CAP would demonstrate project consistency with the CAP.
Project compliance with the applicable reduction measures of the CAP is shown in Table 11.

SB 350 50 Percent Renewable Mandate. Utilities subject to the legislation will be required to increase their renewable energy mix from 33 percent in 2020 to 50 percent in 2030.
Not applicable. This measure would apply to utilities and not to individual development projects. The project would purchase electricity from a utility subject to the SB 350 Renewable Mandate. Specifically, electricity would be supplied to the project by SCE. SCE already meets or exceeds the proposed renewable standards.
SB 350 Double Building Energy Efficiency by 2030. This is equivalent to a 20 percent reduction from 2014 building energy usage compared to current projected 2030 levels.
Not applicable. This measure applies to existing buildings. New structures are required to comply with Title 24 Energy Efficiency Standards that are expected to increase in stringency over time. The project would comply with the applicable Title 24 Energy Efficiency Standards in effect at the time building permits are received.
Low Carbon Fuel Standard. This measure requires fuel providers to meet an 18 percent reduction in carbon content by 2030.
Not applicable. This is a Statewide measure that cannot be implemented by a project applicant or lead agency. However, vehicles accessing the proposed residential buildings at the project site would benefit from the standards.
Mobile Source Strategy (Cleaner Technology and Fuels Scenario). Vehicle manufacturers will be required to meet existing regulations mandated by the LEV III and Heavy‐Duty Vehicle programs. The strategy includes a goal of having 4.2 million zero emission vehicles (ZEVs) on the road by 2030 and increasing numbers of ZEV trucks and buses.
Not applicable. This measure is not applicable to the project. However, future customers can be expected to purchase increasing numbers of more fuel efficient and zero emission cars and trucks each year. Furthermore, delivery trucks and buses that would serve future residents will be made by increasing numbers of ZEV delivery trucks.
Sustainable Freight Action Plan. The plan’s target is to improve freight system efficiency 25 percent by increasing the value of goods and services produced from the freight sector, relative to the amount of carbon that it produces by 2030. This would be achieved by deploying over 100,000 freight vehicles and equipment capable of zero emission operation and maximize near‐zero emission freight vehicles and equipment powered by renewable energy by 2030.
Not applicable. This measure applies to owners and operators of trucks and freight operations. The project would not support truck and freight operations. It is expected that deliveries throughout the State would be made with an increasing number of ZEV delivery trucks, including deliveries that would be made to the project site.
Short‐Lived Climate Pollutant (SLCP) Reduction Strategy. The strategy requires the reduction of SLCPs by 40 percent from 2013 levels by 2030 and the reduction of black carbon by 50 percent from 2013 levels by 2030.
Not applicable. No wood‐burning devices are proposed as part of the project.
SB 375 Sustainable Communities Strategies. Requires Regional Transportation Plans to include a Sustainable Communities Strategy (SCS) for reduction of per capita vehicle miles traveled.
Not applicable. The project does not include the development of a Regional Transportation Plan. Furthermore, the project is not within an SCS priority area.

As shown in Table 11, the project would comply with the applicable reduction measures of the CAP.
The project would also comply with the applicable measures of the 2017 Scoping Plan Update for
compliance with SB 32, as shown in Table 12. Additionally, as previously shown in Table 10, the
project would not exceed the applicable SCAQMD 3,000 MT CO2e threshold of significance for either
2020 and 2030 years. Therefore, the project would be consistent with the applicable local plans,
policies, and regulations and would not conflict with the provisions of AB 32, SB 32, the applicable
air quality plan, or any other state or regional plan, policy or regulation of an agency adopted for the
purpose of reducing GHG emissions. Impacts would be less than significant.

9. Hazards and Hazardous Materials Would the project:
a) Create a significant hazard to the public or the environment through the routine transport, use, or disposal of hazardous materials?
b) Create a significant hazard to the public or the environment through reasonably foreseeable upset and accident conditions involving the release of hazardous materials into the environment?
c) Emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within one‐quarter mile of an existing or proposed school?
d) Be located on a site which is included on a list of hazardous materials sites compiled pursuant to Government Code Section 65962.5 and, as a result, would it create a significant hazard to the public or the environment?
e) For a project located within an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project result in a safety hazard or excessive noise for people residing or working in the project area?
f) Impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan?
g) Expose people or structures, either directly or indirectly to a significant risk of loss, injury or death involving wildland fires?
Environmental Setting
Information and analysis for the Hazards and Hazardous Materials impacts analysis are derived from
the General Plan, online research, and the project‐specific Phase I Environmental Site Assessment
(ESA) included in Appendix E. The Phase I ESA was prepared by Stantec on July 6, 2017.
The Phase I ESA identified several sites within the project vicinity that represent historically
recognized environmental conditions (HRECs) and recognized environmental conditions (RECs);
however, there is no environmental history on the project site itself. In addition, the findings of the

Y:\Publications\Client (PN‐JN)\0327\03270041\ISMND\03270041 City of Santa Ana 7‐Eleven Store ISMND.docx
Phase I ESA concluded there is not a likelihood of contamination on the project site from an off‐site
source, based on constraining factors such as type of regulatory listing, status of the listing, and
groundwater flow.
The following items of note were identified during the Phase I ESA:
The 7 Day Tire & Muffler facility located on the adjoining to the east of the project site (1834
West 1st Street) is listed as a Leaking Underground Storage Tank site, with a ‘Completed Case
Closed as of 11/22/1999’ status. According to the EDR Radius Report listing, a leak from a
waste oil underground storage tank (UST) was discovered at the site in June 1999. The State
Water Resources Control Board (State Water Board) GeoTracker database indicates the leak
was discovered during the tank’s removal. The leak resulted in contamination of the soil,
which was sampled and tested according to U.S. Environmental Protection Agency (EPA)
standards and for Methyl tert‐butyl ether (MTBE). On November 22, 1999, the open case for a
leaking underground storage tank (LUST) on the site was closed by the City of Santa Ana.
Therefore, due to the age of the event and the subsequent agency closure status, this site is
considered a HREC for the project site. Based on proximity, this site meets the definition of a
potential Vapor Encroachment Condition (VEC) as defined by ASTM E2600‐15.
The Anaheim Stations/JFJ Computerized Auto Service facility located approximately 0.05 mile
to the west of the project site (2002 West 1st Street) is listed as a Leaking Underground
Storage Tank site, with a ‘Completed Case Closed as of 10/9/1996’ status. According to the
EDR Radius Report listing, a leak from a gasoline UST(s) was discovered at the site in July 1989
and the leak had impacted groundwater. The GeoTracker database indicates that
tanks/associated piping and soil were removed from the site in 1992 and groundwater was
monitored between 1994 and 1996. In 1996, the LUST case was closed by the City of Santa
Ana and the Santa Ana Regional Water Quality Control Board (RWQCB). Therefore, due to the
age and agency closure status, this site is considered a HREC for the project site. Based on
proximity, this site meets the definition of a potential VEC as defined by the Standard Guide
for VEC screening in accordance to the American Society for Testing and Materials standards
(ASTM E2600‐15).
The Phase I ESA revealed the following RECs in connection with the project site:
The Isaac Incorporated/Isaac, Inc. site located approximately 0.078 mile east of the project
site (1734 W 1st Street) is listed as a LUST site with an ‘Open—Remediation as of 3/3/2004’
status. According to the EDR Radius Report listing, a leak from a gasoline UST(s) was
discovered at the site in July 1987. According to the GeoTracker database, this site is a former
Coca‐Cola bottling plant that had petroleum fueling capabilities and is now in use as a retail
shopping center. The database indicates the fuel release was reported following the removal
of three USTs (two gasoline, one waste oil). Recent groundwater data indicates water quality
objectives for this site have been achieved or nearly achieved, except for benzene. The fact
that benzene is still present in two wells at the site (as of August 2016) is preventing the State
Water Board from issuing a low‐threat UST case closure. Groundwater gauging results

completed at the site in 2014 suggest that groundwater flow direction in the project vicinity is
variable, but appeared to be toward the northwest during the 2014 monitoring event. Based
upon the open case status, variable direction of groundwater, the close proximity to the
project site, and the fact that this site is located upgradient from the project site, this site is
considered a REC for the project site and meets the definition of a potential VEC as defined by
ASTM E2600‐15.
As stated in the Phase I ESA, due to several of the historical and current use of adjoining and nearby properties as various general auto repair shops, gasoline service stations, and auto
paint and body shops they collectively represent a REC for the project site. Based on their
proximity, these sites could also present a potential VEC as defined by ASTM E2600‐15
(Stantec 2017).
Environmental Evaluation
Would the project:
a) Create a significant hazard to the public or the environment through the routine transport, use,
or disposal of hazardous materials?
Less than significant impact. The project site is located within an urbanized built‐up area of the City
of Santa Ana. The project site is bounded by single‐family residences and commercial uses to the
north, single‐family residences and auto‐body repair uses to the east, commercial and auto‐repair
uses to the west, and a vacant lot to the south of the project site. The project site currently contains
a vacant former restaurant building and associated parking lot. The proposed project would
demolish and remove the existing uses and construct a new 7‐Eleven convenience store and fuel
station canopy with associated parking.
During the construction phase of the project, limited amounts of hazardous materials would be used,
including standard construction materials (e.g., paints and solvents) and petroleum based products
(e.g., vehicle fuel and degreasers). The project would be required to comply with all federal, state, and
local standards and regulations while handling, storing, and disposing of these hazardous materials.
Compliance with all federal, state, and local standards and regulations would ensure that project
impacts related to the routine transport, use, and disposal of hazardous materials would be less than
significant. Transport of these materials would be performed by commercial vendors who would be
required to comply with various federal and state laws regarding hazardous materials transportation
(e.g., Federal Motor Carrier Safety Administration regulations and 49 Code of Federal Regulations [CFR]
Parts 100‐185). Additionally, the retail/commercial part of the project would comply with all applicable
laws regarding the use, storage, and disposal of hazardous materials, including provision of spill
prevention kits in accordance with Cal/OSHA standards.
During the operation phase of the project, hazardous or potentially hazardous materials would be
routinely handled, stored, and dispensed on the project site. Since the proposed project includes a
gas station, an underground storage tank (UST) will store gas on the project site. Because of the

nature of the proposed project, and in particular the gas station component, the project would be
subject to routine inspection by federal, state, and local regulatory agencies with jurisdiction over
fuel dispensing facilities. In order to remain operational, the proposed project, including the UST and
all associated fuel delivery infrastructure (i.e., gas pumps), would be required to comply with all
applicable federal, state, and local regulation, including but not limited to those provisions
established by Section 2540.7, Gasoline Dispensing and Service Stations, of the California
Occupational Safety and Health Regulations; Chapter 38, Liquefied Petroleum Gases, of the
California Fire Code; the Resource Conservation and Recovery Act (RCRA); and the Orange County
Fire Authority (OCFA). Collectively, the routine inspection of the gas station, the UST, and all
associated fuel delivery infrastructure, along with the continued mandated compliance with all
federal, state, and local regulations would ensure that the proposed project is operated in a non‐
hazardous manner. Therefore, long‐term impacts associated with handling, storing, and dispensing
of hazardous materials would be less than significant.
b) Create a significant hazard to the public or the environment through reasonably foreseeable
upset and accident conditions involving the release of hazardous materials into the
environment?
Less than significant impact. As mentioned in Impact 3.9(a), any handling, storing, or dispensing
activities associated with hazardous or potentially materials would comply with all applicable
federal, state, and local agencies and regulations. Both short‐term construction and long‐term
operation of the proposed project would comply with all applicable federal, State, and local agencies
and regulations with the policies and programs established by agencies such as the EPA, (Caltrans,
California Department of Toxic Substances Control (DTSC), Cal/OSHA, RCRA, and the OCFA.
Adherence to the applicable policies and programs of these agencies would ensure that any
transport or interaction with hazardous materials would occur in the safest possible manner,
reducing the opportunity for the accidental release of hazardous materials into the environment.
Any handling of hazardous materials would be limited in both quantities and concentrations. As
mandated by OSHA, all hazardous materials stored on‐site would be accompanied by a Material
Safety Data Sheet, which, in the case of accidental release, would inform on‐site personnel as to the
necessary remediation procedures.
Although there are several sites that represent HRECs and RECs in the vicinity of the project site
there is no environmental history on the project site itself. Thus, impacts would be less than
significant.
c) Emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or
waste within one‐quarter mile of an existing or proposed school?
Less than significant impact. There are no schools within a 0.25‐mile radius of the project site. The
schools nearest to the project area are REACH Academy, located at 1512 West Santa Ana Boulevard,
approximately 0.37‐mile northeast, and Abraham Lincoln Elementary School located approximately
0.38 mile southwest of the project site. As there are no schools located within 0.25‐mile of the project

site, impacts related to hazardous emissions or the handling of hazardous or acutely hazardous
materials, substances, or waste within 0.25 mile of an existing school would be less than significant.
d) Be located on a site which is included on a list of hazardous materials sites compiled pursuant to
Government Code Section 65962.5 and, as a result, would it create a significant hazard to the
public or the environment?
Less than significant impact with mitigation incorporated. The project‐specific Phase I ESA
determined the project site is not identified on any lists compiled pursuant to Government Code
Section 65962.5. Although there are several sites that represent HRECs and RECs in the vicinity of the
project site there is no environmental history on the project site itself. Phase II site assessment is not
recommended at this time. However, under MM HAZ‐1, environmental personnel are required to be
present on‐site when the excavation for the new USTs is completed to establish a baseline at the
time of occupancy of the 7‐Eleven convenience store.
e) For a project located within an airport land use plan or, where such a plan has not been adopted,
within two miles of a public airport or public use airport, would the project result in a safety
hazard or excessive noise for people residing or working in the project area?
No impact. The nearest airport is John Wayne Airport located approximately 4.59 miles southeast of
the project site. According to the John Wayne Airport Land Use Plan (2008), the project site is not
located within its planning area (ALUC 2008). Therefore, there would be no associated impacts.
f) Impair implementation of or physically interfere with an adopted emergency response plan or
emergency evacuation plan?
No impact. The proposed project does not possess characteristics that would physically impair or
otherwise interfere with emergency response as outlined in the OCFA Standards of Cover and
Deployment Plan 2014 or evacuation in the project vicinity (OCFA 2014). As such, no impacts would
occur.
g) Expose people or structures, either directly or indirectly, to a significant risk of loss, injury or
death involving wildland fires?
No impact. The proposed project is located in an urban built up area and is surrounded by urban
development on all sides. According to the California Department of Forestry and Fire Prevention
(CAL FIRE), Fire Hazard Severity Zones Map, the project site is not located within or near state
responsibility areas or lands classified as a Very High Fire Hazard Severity Zone. Therefore, the
project would not expose people or structures, either directly or indirectly to impacts involving
wildland fires.
Mitigation Measures
MM HAZ‐1 Environmental personnel shall be present on‐site when the excavation for the new
USTs are completed to establish a baseline at the time of occupancy of the 7‐Eleven
convenience store.

10. Hydrology and Water Quality Would the project:
a) Violate any water quality standards or waste discharge requirements or otherwise substantially degrade surface or groundwater quality?
b) Substantially decrease groundwater supplies or interfere substantially with groundwater recharge such that the project may impede sustainable groundwater management of the basin?
c) Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river or through the addition of impervious surfaces, in a manner which would:
(i) result in substantial erosion or siltation on‐ or off‐site;
(ii) substantially increase the rate or amount of surface runoff in a manner which would result in flooding on‐ or off‐site;
(iii) create or contribute runoff water which would exceed the capacity of existing or planned stormwater drainage systems or provide substantial additional sources of polluted runoff; or
(iv) impede or redirect flood flows?
d) In flood hazard, tsunami, or seiche zones, risk release of pollutants due to project inundation?
e) Conflict with or obstruct implementation of a water quality control plan or sustainable groundwater management plan?
Environmental Evaluation
Would the project:
a) Violate any water quality standards or waste discharge requirements or otherwise substantially
degrade surface or groundwater quality?
Less than significant impact. Project‐related impacts related to water quality can generally occur
over several different periods:

FirstCarbon Solutions 75 Y:\Publications\Client (PN‐JN)\0327\03270041\ISMND\03270041 City of Santa Ana 7‐Eleven Store ISMND.docx
During demolition of existing uses, when risk of pollution exposure is present;
During the earthwork and construction phase, when the potential for erosion, siltation, and sedimentation would be the greatest;
Following construction, before the establishment of ground cover, when the erosion potential
may remain relatively high; and
After project completion, when impacts related to sedimentation would decrease markedly,
but those associated with urban runoff would remain similar to existing conditions.
National Pollutant Discharge Elimination System
Under Section 402 of the Clean Water Act (CWA), the EPA has established regulations under the
National Pollution Discharge Elimination System (NPDES) program to control direct stormwater
discharges from construction activities disturbing one acre or more of land. In California, the State
Water Board administers the NPDES permitting program and is responsible for developing NPDES
permitting requirements. The NPDES program regulates industrial pollutant discharges, which
include construction activities. The State Water Board works in coordination with the RWQCBs to
preserve, protect, enhance, and restore water quality. The City is within the jurisdiction of the Santa
Ana RWQCB.
Short‐term Construction
Dischargers whose projects disturb one or more acres of soil (or whose projects disturb less than
one acre but are part of a larger common plan of development that in total disturbs one or more
acres), are required to obtain coverage under the General Permit for Discharges of Storm Water
Associated with Construction Activity Construction General Permit Order 2009‐0009‐DWQ.
Construction activity subject to this permit includes clearing, grading, and disturbances to the
ground, such as stockpiling or excavation, but it does not include regular maintenance activities
performed to restore the original line, grade, or capacity of the facility. To obtain coverage for
discharges under the General Construction Permit, dischargers are required to electronically file the
Permit Registration Documents, which include a Notice of Intent (NOI), a Storm Water Pollution
Prevention Plan (SWPPP), and other compliance related documents required by the General Permit
and mail the appropriate permit fee to the State Water Board. The Water Quality Management Plan
(WQMP) completed by Feidler Group in October 2018 (Appendix F) has been completed and will be
submitted as part of the application.
Although the project would not be required to comply with NPDES requirements because the project
is anticipated to disturb less than 1 acre, the project’s demolition and construction activities would
be subject to compliance with the pertinent provisions of the City of Santa Ana Municipal Code.
Compliance with the Municipal Code requirements would ensure that the project’s construction‐
related impacts to water quality would be less than significant.

Long‐term Operations
The Municipal Storm Water Permitting Program regulates stormwater discharges from municipal
separate storm sewer (drain) systems (MS4s). Most of these permits are issued to a group of co‐
permittees encompassing an entire metropolitan area. The MS4 permits require the discharger to
develop and implement a Storm Water Management Plan/Program with the goal of reducing the
discharge of pollutants to the maximum extent practicable (MEP).3 The management programs
specify what best management practice (BMP) will be used to address certain program areas. The
program areas include public education and outreach, illicit discharge detection and elimination,
construction and post‐construction, and good housekeeping for municipal operations.
The Orange County Flood Control District, the County of Orange, and the City of Santa Ana, along
with 51 other incorporated cities therein (Permittees), discharge pollutants from their MS4s.
Stormwater and non‐stormwater flows enter and are conveyed through the MS4s and are
discharged to surface water bodies of the Orange County Region. These discharges are regulated
under countywide waste discharge requirements contained in Order No. R8‐2009‐0030 (as amended
by Order No. R8‐2010‐0062), Waste Discharge Requirements for the County of Orange, Orange
County Flood Control District, and the Incorporated cities of Orange County within the Santa Ana
Region Area wide Urban Storm Water Runoff Orange County, which was approved on May 19, 2011.
Order No. R8‐2009‐0030, which serves as an NPDES permit, has expired but remains in effect until
the Santa Ana RWQCB adopts a new permit.
The Permit requires the development and implementation of a program addressing stormwater
pollution issues in development planning for private projects. The primary objectives of the
municipal stormwater program requirements are to (1) effectively prohibit non‐stormwater
discharges; and (2) reduce the discharge of pollutants from stormwater conveyance systems to the
MEP statutory standard. The County Model WQMP was developed as part of the municipal
stormwater program to address stormwater pollution from new development and redevelopment by
the private sector. This WQMP contains a list of the minimum required BMPs that must be employed
for a designated project. The Permittees are required to adopt the Program’s requirements in their
own water quality regulations. Developers must incorporate appropriate WQMP requirements into
their project plans. Each Permittee must approve the project plan as part of their development plan
approval process and prior to issuing grading and building permits for projects covered by the model
WQMP requirements.
The project would be undertaken in accordance with the Orange County Drainage Area Management
Plan (DAMP) (SAMC Section 18‐156, Control of Urban Runoff). Prior to issuance of a grading or
building permit for the project, applicable City agencies would review the project plans and impose
terms, conditions, and requirements on the project, as needed. Additionally, the project would be
subject to compliance with Chapter 19, Article IV—Water Pollution of the City of Santa Ana
Municipal Code, which addresses compliance with the 2003 DAMP.
3 MEP is the performance standard specified in Section 402(p) of the Clean Water Act.

FirstCarbon Solutions 77 Y:\Publications\Client (PN‐JN)\0327\03270041\ISMND\03270041 City of Santa Ana 7‐Eleven Store ISMND.docx
Overall, the project would be subject to compliance with the Orange County DAMP, which requires
the preparation of a WQMP that specifies the proposed BMPs (Appendix F). A project‐specific
WQMP was prepared by the Fiedler Group on August 31, 2018 and revised on October 17, 2018. The
WQMP is in compliance with NPDES, DAMP, and City of Santa Ana Municipal Code requirements,
which would ensure that the long‐term, project‐related impacts on water quality are less than
significant.
b) Substantially decrease groundwater supplies or interfere substantially with groundwater
recharge such that the project may impede sustainable groundwater management of the basin?
Less than significant impact. According to the City of Santa Ana 2015 Urban Water Management
Plan (UWMP), the City receives water from the Lower Santa Ana River groundwater basin, which is
managed by the Orange County Water District, and from imported water from the Metropolitan
Water District of Southern California (Metropolitan). Groundwater is pumped from 20 active wells
throughout the City. As discussed under Impact 18(b), the City anticipates having adequate water
supplies through year 2040. The project is consistent with its underlying General Plan designation of
District Center, and, therefore, its water usage was accounted for in the City’s current UWMP.
A 2018 Geotechnical Investigation Report by Stantec Consulting Services Inc. (Appendix D) for the
project notes that groundwater was encountered at a depth of approximately 30 feet in soil borings
during the investigation. Groundwater levels may fluctuate in the future due to rainfall, irrigation,
broken pipes, or changes in site drainage. Because of the nature of the proposed project, and in
particular the gas station, the project would be subject to routine inspection by federal, State, and
local regulatory agencies with jurisdiction over fuel dispensing facilities. In order to remain
operational, the proposed project, including the UST and all associated fuel delivery infrastructure
(i.e., gas pumps), would be required to comply with all applicable federal, State, and local regulation,
including but not limited to those provisions established by Section 2540.7, Gasoline Dispensing and
Service Stations, of the Cal/OSHA regulations; Chapter 38, Liquefied Petroleum Gases, of the
California Fire Code; RCRA; and the OCFA. Collectively, the routine inspection of the gas station, the
UST, and all associated fuel delivery infrastructure along with the continued mandated compliance
with all federal, state, and local regulations would ensure that the proposed project is operated in a
non‐hazardous manner which will not interfere with groundwater recharge. Thus, project
implementation would therefore result in a less than significant impact to groundwater supplies.
c) Substantially alter the existing drainage pattern of area, including through the alteration of the
course of a stream or river or through the addition of impervious surfaces, in a manner which
would:
(i) result in substantial erosion or siltation on‐ or off‐site;
Less than significant impact. The City’s stormwater collection system includes catch basins, drainage
basins, pumping stations, and force mains. Project construction activities such as demolition,
grading, paving, and site improvements may result in loose sediment, which can be transported by
surface water or wind into nearby storm drains and waterways.

The proposed project would not alter the course of a stream or river, as the Santa Ana River is
located 0.87 mile west of the project area. The project applicant proposes to install an underground
infiltration system compliant with low impact development (LID) requirements in conjunction with
the construction of a new 7‐Eleven convenience store and fuel station canopy in order to retain the
existing drainage patterns which will continue to sheet flow southeasterly. The project would involve
construction in an area that is currently covered by impervious surfaces and the project proposes to
reduce the impervious surfaces on the project site by 2,877 square feet. The project would not
substantially alter the existing drainage pattern of the site in a manner that would result in
substantial erosion or siltation on‐ or off‐site. The on‐site stormwater will be mitigated by an
underground infiltration system. The existing drainage patterns and topography will be maintained.
In other words, drainage will continue to sheet flow southeasterly. Wherever possible, drainage will
be diverted into nearby landscaped areas for pretreatment of sediments and trash. A trench drain is
designed along the southeast driveway to capture any remaining runoff and drain it into the
proposed underground infiltration system.
Recommendations from the Geotechnical Investigation Report, such as designing pavement and
slopes to ensure adequate drainage away from the structures, also will be incorporated into the
project design. As such, impacts related to the alteration of existing drainage patterns in the area
that could result in substantial erosion or siltation on‐ or off‐site would be less than significant.
(ii) substantially increase the rate or amount of surface runoff in a manner which would result in
flooding on‐ or offsite;
Less than significant impact. The City’s stormwater collection system includes catch basins, drainage
basins, pumping stations, and force mains. Project construction activities such as demolition,
grading, paving, and site improvements may result in loose sediment that can be picked up by
surface water or wind into nearby storm drains and into waterways.
The proposed project would not alter the existing drainage pattern of the site and would not alter
the path of a stream or river, as explained above. The project applicant would install an underground
infiltration system compliant with LID requirements in conjunction with the construction of a new 7‐
Eleven convenience store and fuel station canopy in order to retain drainage patterns.
Recommendations from the Geotechnical Investigation Report will also be incorporated in the
design and construction of the project, such as designing pavement and slopes to ensure adequate
drainage away from the structures. As such, impacts related to the alteration of existing drainage
patterns in the area that could result in flooding on‐ or off‐site would be less than significant.
(iii) create or contribute runoff water which would exceed the capacity of existing or planned
stormwater drainage systems or provide substantial additional sources of polluted runoff; or
Less than significant impact. The project would be served by the City’s stormwater drainage system.
Construction activities such as demolition, grading, and paving could introduce additional pollutants
and sediment into water runoff and flow into nearby storm drains. As part of the project, a
Preliminary WQMP has been prepared in compliance with the NPDES requirements of the CWA. The
WQMP contains proposed BMPs such as site design techniques that store, infiltrate, evapotranspire,

bio‐filter, or detain runoff close to its source. Continuous use and operation of the site would not
create or contribute runoff water that would exceed the capacity of existing stormwater drains on
the project site with implementation of these BMPs. Therefore, impacts are considered less than
significant.
(iv) impede or redirect flood flows?
No impact. The project site is not located within a floodplain. The project will not add additional
impervious surfaces or alter the course of a stream or river. Therefore, there are no impacts related
to impeding or redirecting flood flow would occur.
d) In flood hazard, tsunami, or seiche zones, risk release of pollutants due to project inundation?
No impact. The project site is not located within a floodplain or flood hazard zone. A seiche is an
earthquake or slide‐induced wave that can be generated in an enclosed body of water. There is no
enclosed body of water in the project vicinity.
A tsunami is a sea wave generated by an earthquake, landslide, volcanic eruption, or even a large
meteor hitting the ocean. An event such as an earthquake creates a large displacement of water
resulting in a rise or mounding at the ocean surface that moves away from this center as a sea wave.
Tsunamis generally affect coastal communities and low‐lying (low‐elevation) river valleys in the
vicinity of the coast. Buildings closest to the ocean and near sea level are most at jeopardy.
According to the California Geological Survey Orange County Tsunami Inundation Maps, the project
site is not located within a tsunami inundation area (DOC 2019). A seiche is an earthquake or slide‐
induced wave that can be generated in an enclosed body of water. There is no enclosed body of
water in the project vicinity. Therefore, the project is not in a seiche zone.
Potential risk from mudflow (e.g., mudslide, debris flow) does not exist within the project area, as
steep slopes are not located in the project vicinity. Therefore, because the project is not in a flood
hazard, tsunami, or seiche zone, there would be no associated impacts related project
implementation would not risk release of pollutants from inundation by seiche, tsunami, or
mudflow. No impact would occur.
e) Conflict with or obstruct implementation of a water quality control plan or sustainable
groundwater management plan?
Less than significant impact. The project site has little potential for groundwater recharge due to
poorly drained soils and shallow groundwater levels. The project would not conflict with the County
Watershed Program and the County’s NPDES program. That proposed construction would disturb
less than 1 acre of land. The on‐site underground infiltration system would mitigate runoff from the
project site. Appendix F includes BMPs that will ensure reduction of pollutants from construction
activities potentially entering surface waters. Therefore, construction impacts related to water
quality control plan or groundwater management plan consistency would be less than significant.

In addition, Santa Ana Municipal Utility Services would provide potable water to the project site. As
a result, the project would not conflict with or obstruct a sustainable groundwater management
plan. Therefore, operational impacts related to obstructing implementation of a water quality
control plan or groundwater management plan would be less than significant.

b) Cause a significant environmental impact due to a conflict with any land use plan, policy, or regulation adopted for the purpose of avoiding or mitigating an environmental effect?
Environmental Evaluation
Would the project:
a) Physically divide an established community?
Less than significant impact. The physical division of an established community typically refers to
the construction of a linear feature, such as an interstate highway or railroad tracks, or removal of a
means of access, such as a local bridge that would impact mobility within an existing community of
between a community and outlying area. The project does not involve any such features, and would
not remove any means of access or impact mobility. Furthermore, no streets or sidewalks would be
permanently closed as a result of project development.
The project area is built out with a variety of uses. The proposed project would not involve changes to
any circulation facilities in the surrounding community. The nature of the project land use would be
consistent with the surrounding uses. The project would not introduce land uses inconsistent with
development in the local area or affect existing land use relationships. As such, the project would not
physically divide an established community and impacts are considered less than significant.
b) Cause a significant environmental impact due to a conflict with any land use plan, policy, or
regulation adopted for the purpose of avoiding or mitigating an environmental effect?
Less than significant impact. The City of Santa Ana General Plan and Zoning Ordinance defines the
permitted land uses and the corresponding development standards within the City. The project site
is currently zoned as Light Industrial (M‐1) and the City of Santa Ana General Plan designation is
General Commercial. Although service stations are permitted in the M‐1 zone, a convenience store
greater than 2,000‐square‐feet in size is not permitted in the M‐1 zone. Therefore, the proposed
project would seek an Amendment Application (Zone Change) to change the zoning from M‐1 to
General Commercial (C‐2) to allow for a 2,480‐square‐foot convenience store. The C‐2 zoning
permits a convenience store with the approval and issuance of a Conditional Use Permit for the
after‐hours operations. The surrounding parcels north and east of the project site are zoned C‐2,
therefore a zone change would be consistent with the existing surrounding General Plan and Zoning

Environmental Evaluation
Would the project:
a) Result in the loss of availability of a known mineral resource that would be of value to the region
and the residents of the state?
No impact. According to the City’s Land Use Element of the General Plan, there are no significant
mineral aggregate resource areas (SMARA) designations within the City (City of Santa Ana 1998). The
closest regionally significant resources are north of the City, along the Santa Ana River within the
cities of Orange and Anaheim. Santa Ana is a highly urbanized city and does not have any active
mining operations within the city limits. The project site is currently developed and project
implementation would not result in the loss of availability of a known mineral resource; thus, no
impacts would occur.
b) Result in the loss of availability of a locally‐important mineral resource recovery site delineated
on a local general plan, specific plan or other land use plan?
No impact. As stated above, the City’s Land Use Element of the General Plan does not identify any
mineral resource zones within the City (City of Santa Ana 1998). The project site is zoned as M‐1 by
the City of Santa Ana Zoning Ordinance and the proposed project would rezone to C‐2, neither of
which permit mining activities. The project site is not a site that contains mineral resources that are
locally important to the area; thus, no impacts would occur.

Environmental Evaluation
Introduction
This section describes the existing noise setting and potential effects from project implementation
on the site and its surrounding area. Descriptions and analysis in this section are based on noise
modeling performed by FCS (Traffic Noise Appendix Data, FCS 2019 [Appendix G]).
Environmental Setting
Characteristics of Noise and Groundborne Vibration
Noise is defined as unwanted sound. Sound levels are usually measured and expressed in decibels (dB),
with 0 dB corresponding roughly to the threshold of hearing. Most of the sounds that we hear in the
environment do not consist of a single frequency, but rather a broad band of frequencies, with each
frequency differing in sound level. The intensities of each frequency add together to generate a sound.
Noise is typically generated by transportation, specific land uses, and ongoing human activity.
The standard unit of measurement of the loudness of sound is the dB. The 0 point on the dB scale is
based on the lowest sound level that the healthy, unimpaired human ear can detect. Changes of 3 dB
or less are only perceptible in laboratory environments. A change of 3 dB is the lowest change that can
be perceptible to the human ear in outdoor environments. While a change of 5 dB is considered to be
the minimum readily perceptible change to the human ear in outdoor environments.

FirstCarbon Solutions 85 Y:\Publications\Client (PN‐JN)\0327\03270041\ISMND\03270041 City of Santa Ana 7‐Eleven Store ISMND.docx
Since the human ear is not equally sensitive to sound at all frequencies, the A‐weighted decibel scale
(dBA) was derived to relate noise to the sensitivity of humans. The scale gives greater weight to the
frequencies of sound to which the human ear is most sensitive. Furthermore, the A‐weighted sound
level is the basis for a number of various sound level metrics, including the day/night sound level
(Ldn) and the Community Noise Equivalent Level (CNEL), both of which represent how humans are
more sensitive to sound at night. In addition, the equivalent continuous sound level (Leq) is the
average sound energy of time‐varying noise over a sample period and the Lmax is the maximum
instantaneous noise level occurring over a sample period.
Groundborne vibration is typically only an annoyance to people indoors where the vibration results
in noticeable shaking of a building. When assessing annoyance from groundborne vibration,
vibration is typically expressed as root mean square velocity in units of decibels of 1 micro‐inch per
second. To distinguish these vibration levels referenced in decibels from noise levels referenced in
decibels, the unit is written as “VdB.”
In extreme cases, excessive groundborne vibration has the potential to cause structural damage to
buildings. Common sources of groundborne vibration include construction activities such as blasting,
pile driving and operating heavy earthmoving equipment. However, construction vibration impacts
on building structures are generally assessed in terms of peak particle velocity (PPV). For purposes of
this analysis, project related impacts are expressed in terms of PPV.
Regulatory Framework
The project site is located in the City of Santa Ana and this analysis was performed using the City’s
noise regulations. The City of Santa Ana addresses noise in its policies and regulations of the Noise
Element of its General Plan (City of Santa Ana 1982) and in the City’s Code of Ordinances (City of
Santa Ana 2018). These policies and regulations are summarized below.
General Plan
The City of Santa Ana has established the following policies that are applicable to the proposed
project and that are designed to prevent significant increases in noise levels in the community and to
minimize the adverse effects of currently‐existing noise sources:
Require consideration of noise generation potential and susceptibility to noise impacts in the
siting, design and construction of new developments.
Require mitigating site and building design features, traffic circulation alternatives, insulation,
and other noise prevention measures of those new developments which generate high noise
levels.
Code of Ordinances
The City of Santa Ana Municipal Code contains Noise Control Ordinances in Article VI of Chapter 18,
Health and Sanitation. Sections of the Municipal Code that are applicable to the proposed project
are summarized below.

Section 18‐312 establishes exterior noise standards, limiting noise levels at receiving residential
homes to 55 dBA during the daytime hours between 7:00 a.m. and 10:00 p.m., and 50 dBA during
the nighttime hours between 10:00 p.m. and 7:00 a.m. Noise generation at any location within the
City of Santa Ana, when measured on any other residential property, must not exceed the following:
1. The above noise standard for a cumulative period of more than 30 minutes in any hour; or
2. The noise standard plus 5 dBA for a cumulative period of more than 15 minutes in any hour; or
3. The noise standard plus 10 dBA for a cumulative period of more than 5 minutes in any hour; or
4. The noise standard plus 15 dBA for a cumulative period of more than 1 minute in any hour; or
5. The noise standard plus 20 dBA for any period of time.
If the ambient noise level exceeds any of the first four noise limit categories above, the cumulative
period applicable to that category shall be increased to reflect the ambient noise level. If the
ambient noise level exceeds the fifth noise limit category, the maximum allowable noise level under
that category shall be increased to reflect the maximum ambient noise level.
Section 18‐313 establishes interior noise standards, limiting noise levels at receiving residential
homes to 55 dBA during the daytime hours between 7:00 a.m. and 10:00 p.m., and 45 dBA during
the nighttime hours between 10:00 p.m. and 7:00 a.m. Noise generation at any location within the
City of Santa Ana, when measured within any other dwelling unit on any residential property, must
not exceed the following:
1. The interior noise standard for a cumulative period of more than 5 minutes in any hour; or
2. The interior noise standard plus 5 dBA for a cumulative period of more than 1 minute in any
hour; or
3. The interior noise standard plus 10 dBA for any period of time.
If the ambient noise level exceeds any of the first two noise limit categories above, the cumulative
period applicable to that category shall be increased to reflect the ambient noise level. If the
ambient noise level exceeds the third noise limit category, the maximum allowable noise level under
that category shall be increased to reflect the maximum ambient noise level.
Section 18‐314 of the Code notes that noise sources associated with construction, repair,
remodeling, or grading of any real property are exempt from the noise performance standards of the
Municipal Code, provided said activities do not take place between the hours of 8:00 p.m. and 7:00
a.m. on weekdays, including Saturday, or any time on Sunday or a federal holiday.

Impact Analysis
Would the project result in:
a) Generation of a substantial temporary or permanent increase in ambient noise levels in the
vicinity of the project in excess of standards established in the local general plan or noise
ordinance, or applicable standards of other agencies?
Short Term Construction Impacts
Less than significant impact with mitigation incorporated. A significant impact would occur if
construction activities would generate a substantial temporary increase in ambient noise levels
outside of the City’s permissible hours for noise producing construction activities that would result in
annoyance or sleep disturbance for nearby sensitive receptors. Noise impacts from construction
activities associated with the project would be a function of the noise generated by construction
equipment, equipment location, sensitivity of nearby land uses, and the timing and duration of the
construction activities.
Construction Traffic Noise
One type of noise impact that could occur during project construction would result from the increase
in traffic flow on local streets, associated with the transport of workers, equipment, and materials to
and from the project site. The transport of workers and construction equipment and materials to the
project site would incrementally increase noise levels on access roads leading to the site. Because
project construction workers and construction equipment would use existing routes, noise from
passing trucks would be similar to existing vehicle‐generated noise on these local roadways.
Furthermore, project‐related construction trips would not be expected to double the traffic volumes
along any roadway segment in the project vicinity and would thus not result in a perceptible change in
existing traffic noise levels. For these reasons, short‐term intermittent noise from trucks would be
minor when averaged over a longer time‐period and would not be expected to exceed existing peak
noise levels in the project vicinity. Therefore, construction‐related impacts associated with worker
commute and equipment transport to the project site would be less than significant.
Construction Equipment Noise
Construction noise levels are rarely steady in nature and often fluctuate depending on the type and
number of equipment being used at any given time. In addition, there are times where large
equipment is not operating and construction site noise would be at or near normal ambient levels.
Construction is completed in discrete steps, each of which has its own mix of equipment and its own
noise characteristics. These various sequential phases would change the character of the noise
generated on the site and, therefore, the noise levels surrounding the site as construction
progresses. Despite the variety in the type and size of construction equipment, similarities in the
dominant noise sources and patterns of operation allow construction related noise ranges to be
categorized by work phase.
The site preparation phase, which includes demolition, excavation, and grading activities, would
generate the highest noise levels because the noisiest construction equipment is earthmoving

equipment. Earthmoving equipment includes excavating machinery and compacting equipment,
such as bulldozers, draglines, backhoes, front loaders, roller compactors, scrapers, and graders.
Typical operating cycles for these types of construction equipment may involve 1 or 2 minutes of full
power operation followed by 3 or 4 minutes at lower power settings.
Construction of the proposed project is expected to require the use of front‐end loaders, tractors,
backhoes, concrete/industrial saws, rubber tire dozers, cranes, forklifts, pavers, rollers, air
compressors, excavators, haul trucks, water trucks, concrete mixer trucks, and pickup trucks. The
maximum noise level generated by each concrete mixing truck is assumed to be 85 dBA Lmax at 50
feet from this equipment. Each dozer would also generate 85 dBA Lmax at 50 feet. The maximum
noise level generated by excavators is approximately 85 dBA Lmax at 50 feet. Each doubling of sound
sources with equal strength increases the noise level by 3 dBA. Assuming that each piece of
construction equipment operates at some distance from the other equipment, a reasonable worst‐
case combined noise level during this phase of construction would be 90 dBA Lmax at a distance of 50
feet from the acoustic center of a construction area. This would result in a reasonable worst‐case
hourly average of 86 dBA Leq. The acoustical center reference is used because construction
equipment must operate at some distance from one another on a project site, and the combined
noise level as measured at a point equidistant from the sources (acoustic center) would be the
worst‐case maximum noise level.
The nearest off‐site noise‐sensitive receptor to the proposed project site is the residential home
located east of the project site across South Daisy Avenue. This home’s nearest façade would be
located approximately 120 feet from the acoustic center of construction activity where multiple
pieces of heavy machinery would potentially operate, simultaneously, at the project site. At this
distance, worst‐case construction noise levels could range up to approximately 82 dBA Lmax,
intermittently, and could have an hourly average of up to 78 dBA Leq, at the nearest façade of this
residential home.
Although there could be a relatively high single event noise exposure potential causing an
intermittent noise nuisance, the effect of construction noise levels on longer‐term (hourly or daily)
ambient noise levels would be small but could result in annoyance or sleep disturbances at nearby
sensitive receptors if construction activities are not limited to the permissible construction hours
established by the City of Santa Ana Municipal Code. Therefore, noise producing construction
activities shall be restricted to the hours between 7:00 a.m. and 8:00 p.m. Monday through
Saturday; construction activities are prohibited on Sundays and federal holidays. Restricting
construction activities to these stated time‐periods, as well as implementing the best management
noise reduction techniques and practices (both outlined in MM NOI‐1), would ensure that
construction noise would not result in a substantial temporary increase in ambient noise levels that
would result in annoyance or sleep disturbance to nearby sensitive receptors. Therefore, the
potential short‐term construction noise impacts to ambient noise levels in the vicinity of the project
site would be reduced to less than significant levels with mitigation incorporated.

Operational/Stationary Source Noise Impacts
Less than significant impact. A significant impact would occur if operational noise levels generated
by stationary noise sources at the proposed project site would result in a substantial permanent
increase in ambient noise levels in excess of any of the noise performance thresholds established in
the City of Santa Ana Municipal Code. The City has established an exterior noise limit of 55 dBA Leq
hourly average during daytime hours, and a noise limit of 50 dBA Leq hourly average during nighttime
hours, for receiving residential land uses. However, the City notes that if the existing ambient noise
level exceeds these standards, the ambient noise level shall be considered the standard.
Existing ambient noise levels in the project vicinity are dominated by traffic noise. Based on the
traffic noise modeling described in the analysis below, the existing ambient noise level at the
property line of the nearest noise sensitive receptor to the project site is approximately 63 dBA
CNEL. Therefore, since the daytime and nighttime average noise levels currently exceed the City’s
noise standards, the ambient noise level shall be considered the standard.
The City has not established a threshold to determine what constitutes a substantial increase.
Audible increases in noise levels generally refer to a change of 3 dBA or more, as this level has been
found to be barely perceptible to the human ear in outdoor environments. A change of 5 dBA is
considered the minimum readily perceptible change to the human ear in outdoor environments.
Therefore, for purposes of this analysis, an increase of greater than 3 dBA above existing ambient
noise levels would be considered a substantial permanent increase in ambient noise levels.
The proposed project would include new stationary noise sources, including new mechanical
ventilation equipment and parking lot activities.
Mechanical Equipment Operations
Implementation of the project would include operation of new mechanical ventilation equipment.
Noise levels from typical commercial‐grade mechanical ventilation equipment systems range up to
approximately 60 dBA Leq at a distance of 25 feet.
Proposed mechanical ventilation systems could be located as close as 125 feet from the nearest off‐
site noise‐sensitive receptor, which is the single‐family residential home located at 109 South Daisy
Avenue. At this distance, operational noise levels generated by this equipment would range up to
approximately 46 dBA Leq at this nearest noise‐sensitive receptor. Existing traffic noise levels along
West Fir Street adjacent to the project site range up to approximately 68 dBA CNEL as measured at
50 feet from the centerline of the outermost travel lane. The nearest residential receptor, located at
109 South Daisy Avenue, is located approximately 130 feet from the centerline of the outermost
travel lane. At this distance, existing traffic noise levels would attenuate to approximately 63 dBA
CNEL. Therefore, existing ambient noise levels at the nearest sensitive receptor in the project vicinity
are a minimum of 63 dBA CNEL.
The calculated reasonable worst‐case noise levels resulting from the operation of mechanical
ventilation equipment of 46 dBA Leq would not exceed existing ambient noise levels, averaging 63
dBA CNEL at the nearest off‐site receptor, by 3 dBA or more. Therefore, operational noise levels due

to mechanical ventilation equipment would not result in a substantial permanent increase in ambient
noise levels in excess of any of the noise performance thresholds, and would represent a less than
significant impact.
Parking Lot Activities
Typical parking lot activities include people conversing, doors shutting, and vehicles idling, which
generate noise levels ranging from approximately 60 dBA to 70 dBA Lmax at 50 feet. These activities
are expected to occur throughout the day, as visitors and staff arrive and leave parking lot areas at
the project site. This project would also include periodic parking lot noise from the loading and
unloading activities of small delivery trucks.
The nearest noise‐sensitive receptor to the gas station component and parking areas of the
proposed project is the single‐family residential home located at 109 South Daisy Avenue. This
residence would be located approximately 110 feet from the acoustic center of parking lot activities
at the project site. At this distance, noise levels associated with daily parking lot activities would
range up to approximately 63 dBA Lmax at the nearest residential property line.
Noise levels resulting from parking lot activities at the proposed project site would not exceed
existing ambient noise levels at the nearest off‐site receptor by 3 dBA or more. Therefore,
operational noise levels due to parking lot activities would not result in a substantial permanent
increase in ambient noise levels in excess of any of the noise performance thresholds, and would
represent a less than significant impact.
Therefore, operational noise levels generated by stationary noise sources at the proposed project
site would have a less than significant impact to existing ambient noise levels.
Operational/Mobile Source Noise Impacts
Less than significant impact. A significant impact would occur if implementation of the proposed
project would result in a substantial increase in ambient noise levels compared with noise levels
existing without the project. However, the City does not define “substantial increase.” Therefore, for
the purpose of this analysis, a substantial increase is based on the following criteria: (1) a
characteristic of noise is that audible increases in noise levels generally refer to a change of 3 dBA or
more, as this level has been found to be barely perceptible to the human ear in outdoor
environments, and (2) a change of 5 dBA is considered the minimum readily perceptible change to
the human ear in outdoor environments. Therefore, for purposes of this analysis, a significant impact
would occur if the project would cause the CNEL to increase by any of the following:
5 dBA or more even if the CNEL would remain below normally acceptable levels for a receiving
land use.
3 dBA or more, thereby causing the CNEL in the project vicinity to exceed normally acceptable
levels and result in noise levels that would be considered conditionally acceptable for a
receiving land use.
1.5 dBA or more where the CNEL currently exceeds conditionally acceptable levels.

Traffic noise levels along selected roadway segments in the project vicinity were modeled using the
Federal Highway Administration (FHWA) Traffic Noise Prediction Model (FHWA‐RD‐77‐108). Site‐
specific information, such as roadway traffic volumes, roadway active width, source‐to‐receiver
distances, travel speed, noise source, and receiver heights is entered, along with the percentages of
automobiles, medium trucks, and heavy trucks that the traffic is made up of throughout the day,
amongst other variables. The daily traffic volumes were obtained from the traffic analysis prepared
for the project by RK Engineering Group (RKEG 2018). The traffic volumes described here correspond
to the Existing Without Project conditions traffic scenario as described in the transportation analysis.
The model inputs and outputs—including the 60 dBA, 65 dBA, and 70 dBA CNEL noise contour
distances—are provided in Appendix G of this document. Table 13 shows a summary of the traffic
noise levels for Existing, Existing Plus Project, Project Opening Year (2020) Without Project, and

The highest traffic noise level increase with implementation of the project would occur along South
Daisy Avenue between West First Street and Project Driveway 2 under existing plus project
conditions. The modeling results show that traffic noise levels with the project would range up to
55.0 dBA CNEL as measured at 50 feet from the centerline of the outermost travel lane. The resulting

noise levels are below the normally acceptable threshold for receiving land uses adjacent to this
roadway segment. This increase is well below the 5 dBA increase that would be considered a
substantial permanent increase in noise levels compared with noise levels that would exist without
the project. Therefore, impacts from project‐related traffic noise levels would not result in a
substantial permanent increase in traffic noise levels in excess of applicable standards, and this
impact would be less than significant.
b) Generation of excessive groundborne vibration or groundborne noise levels?
Less than significant impact. This section analyzes both construction and operational groundborne
vibration impacts. The City of Santa Ana has not adopted criteria for construction groundborne
vibration impacts. Therefore, for purposes of this analysis, the Federal Transit Administration (FTA)
vibration impact criteria are utilized to determine the significance of project‐related construction
groundborne vibration levels. The FTA has established industry accepted standards for vibration
impact criteria and impact assessment. These guidelines are published in its Transit Noise and
Vibration Impact Assessment document. The FTA guidelines thresholds for construction vibration
impacts for various structural categories, as shown in Table 14.
Table 14: Federal Transit Administration Construction Vibration Impact Criteria
Building Category PPV (in/sec) Approximate VdB
I. Reinforced—Concrete, Steel or Timber (no plaster) 0.5 102
II. Engineered Concrete and Masonry (no plaster) 0.3 98
III. Non Engineer Timber and Masonry Buildings 0.2 94
IV. Buildings Extremely Susceptible to Vibration Damage 0.12 90
Source: FTA 2019.
Short‐term Construction Vibration Impacts
A significant impact would occur if existing structures at the project site or in the project vicinity
would be exposed to groundborne vibration levels in excess of levels established by the FTA’s
Construction Vibration Impact Criteria for the listed type of structure, as shown in Table 14.
Of the variety of equipment that would be used during construction, small vibratory rollers would
produce the greatest groundborne vibration levels. Small vibratory rollers produce groundborne
vibration levels ranging up to 0.101 inch per second (in/sec) PPV at 25 feet from the operating
equipment. Impact equipment such as pile drivers is not expected to be used during construction of
this project.
The closest structure to the construction footprint is the DC Auto Electric building located
immediately adjacent to the project site to the west. This building would be located approximately
25 feet from the nearest on‐site location where the largest heavy construction equipment would

operate. At this distance, construction‐related groundborne vibration levels could range up to 0.101
PPV from the operation of a small vibratory roller.
Construction equipment would also operate near the western project boundary during the site
preparation phase of construction. Of the variety of equipment that would operate adjacent to the
project boundary, backhoes would produce the greatest groundborne vibration levels. This
equipment may be operated as close as 10 feet to the DC Auto Electric building located to the west.
At this distance, construction‐related groundborne vibration levels could range up to 0.202 PPV from
the operation of a backhoe. These groundborne vibration levels are below the industry standard
vibration damage criteria of 0.5 PPV for this type of structure, a building of reinforced concrete,
steel, or timber (no plaster) construction. Therefore, impacts resulting from construction‐related
groundborne vibration levels would be less than significant.
Operational Vibration Impacts
A significant impact would occur if the project would generate excessive groundborne vibration
levels at sensitive receptors in the project vicinity.
The proposed project would not include any permanent sources of vibration that would expose
persons in the project vicinity to groundborne vibration levels that could be perceptible without
instruments by a reasonable person at any receiving sensitive receptor in the project vicinity.
Therefore, project operational groundborne vibration level impacts are considered less than
significant.
c) For a project located within the vicinity of a private airstrip or an airport land use plan or, where
such a plan has not been adopted, within two miles of a public airport or public use airport,
would the project expose people residing or working in the project area to excessive noise
levels?
No impact. A significant impact would occur if the project would expose people residing or working
in the project area to excessive noise levels for a project located within the vicinity of a private
airstrip or an airport land use plan or, where such a plan has not been adopted, within 2 miles of a
public airport or public use airport.
The project site is not located within the vicinity of a private airstrip. The nearest public airport to
the project site is John Wayne Airport, located approximately 4.5 miles south of the project site.
Because of the distance from and orientation of the airport runways, the project site is located well
outside of the 65 dBA CNEL airport noise contours. Therefore, implementation of the project would
not expose people residing or working in the project area to excessive noise levels associated with
airport activity. Therefore, no impacts associated with private airstrip noise would occur.
Mitigation Measures
MM NOI‐1 To reduce potential construction noise impacts, the following multi‐part mitigation
measure shall be implemented for the proposed project:

Y:\Publications\Client (PN‐JN)\0327\03270041\ISMND\03270041 City of Santa Ana 7‐Eleven Store ISMND.docx
The construction contractor shall ensure that all equipment driven by internal
combustion engines shall be equipped with mufflers, which are in good condition
and appropriate for the equipment.
The construction contractor shall ensure that unnecessary idling of internal combustion engines (i.e., idling in excess of 5 minutes) is prohibited.
The construction contractor shall utilize “quiet” models of air compressors and
other stationary noise sources where technology exists.
At all times during project grading and construction, the construction contractor
shall ensure that stationary noise‐generating equipment shall be located as far as
practicable from sensitive receptors and placed so that emitted noise is directed
away from the nearest residential land uses.
The construction contractor shall designate a noise disturbance coordinator who would be responsible for responding to any local complaints about construction
noise. The disturbance coordinator would determine the cause of the noise
complaints (starting too early, bad muffler, etc.) and establishment reasonable
measures necessary to correct the problem. The construction contractor shall
visibly post a telephone number for the disturbance coordinator at the
construction site.
The construction contractor shall limit construction activities to the hours
between 7:00 a.m. and 8:00 p.m. Monday through Saturday. Construction
activities are prohibited on Sundays and federal holidays.

b) Displace substantial numbers of existing people or housing, necessitating the construction of replacement housing elsewhere?
Environmental Evaluation
Would the project:
a) Induce substantial unplanned population growth in an area, either directly (for example, by
proposing new homes and businesses) or indirectly (for example, through extension of roads or
other infrastructure)?
Less than significant impact. The CEQA Guidelines identify a project as growth inducing if it fosters
economic or population growth or the construction of additional housing either directly or indirectly
in the surrounding environment (CEQA Guidelines § 15126.2(d)). New employees from commercial
or industrial development and new populations from residential development represent direct forms
of growth. These direct forms of growth have a secondary effect of expanding the size of local
markets and inducing additional economic activity in the area.
Under CEQA, growth inducement is not considered necessarily detrimental, beneficial, or of
particular significance to the environment. Typically, the growth‐inducing potential of a project
would be considered substantial if it is unplanned or fosters growth or a concentration of population
in excess of what is assumed in pertinent master plans, land use plans, or in projections made by
regional planning agencies (e.g., SCAG).
The proposed project would require a temporary construction and permanent operational
workforce, both of which could induce population growth in the project area. The temporary
workforce would be needed to construct the convenience store and fueling station canopy and
associated improvements. The number of construction workers needed during any given time period
would largely depend on the specific stage of construction and would be temporary. Because of the
nature of the proposed project, the types of labor skills required for the proposed project are
typically filled by workers who are already present in the local labor force. As such, the employees
would not increase the population since it is likely the workers would be employed from the

surrounding areas of Orange County. Once operational, the employees working at the 7‐Eleven
convenience store would also likely be from the local labor force. Therefore, there would be less
than significant impacts associated with growth inducement.
b) Displace substantial numbers of existing people or housing, necessitating the construction of
replacement housing elsewhere?
No impact. The proposed project would not displace existing people or housing, necessitating the
construction of replacement housing elsewhere, because the proposed project is proposed on a
vacant, former restaurant site that does not contain existing housing that would be removed or
affected by the proposed project. Therefore, there will be no impact on existing housing,
necessitating the construction of replacement housing elsewhere.
Mitigation Measures
None.

15. Public Services Would the project result in substantial adverse physical impacts associated with the provision of new or physically altered governmental facilities, need for new or physically altered governmental facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times or other performance objectives for any of the public services:
a) Fire protection?
b) Police protection?
c) Schools?
d) Parks?
e) Other public facilities?
Environmental Setting
The OCFA provides fire protection services to the City of Santa Ana. OCFA provides both fire
protection and emergency medical response services to the City of Santa Ana. The OCFA operates 10
stations throughout Santa Ana, and has access to an additional 72 stations in its service area (OCFA
2019). According to the City of Santa Ana Public Safety Element, each station covers a service radius
of approximately 1.5 miles throughout the City of Santa Ana. The first Fire unit response goal is less
than 5 minutes (City of Santa Ana 1982). The closest fire station to the project site is OCFA Station
No. 73 located approximately 0.22 miles south.
The Santa Ana Police Department (SAPD) provides police protection to the City of Santa Ana. The
Santa Ana General Plan Public Safety Element indicates the City’s central police station is located in
Civic Center approximately 0.94 miles northeast of the project site.
The Education Element of the City of Santa Ana General Plan indicates the City is served by four
school districts: Santa Ana Unified School District (SAUSD), Garden Grove Unified School District,
Tustin Unified School District, and Orange Unified School District (City of Santa Ana 1988). SAUSD
accounts for over 90 percent of school resources in the City.
The City of Santa Ana contains a city library system of a central library in Civic Center Plaza and two
branch libraries in the western section of Santa Ana; the McFadden, and Newhope Branches.
According to the Santa Ana General Plan Open Space, Parks, and Recreation Element, the City has
about 400 acres of public park and recreation facilities distributed throughout the City (City of Santa
Ana 1982). Approximately 2 acres of open space exist for each 1,000 residents.

On March 15, 2019, communications via e‐mail were sent out to OCFA, SAPD, SAUSD, Santa Ana Library,
and Santa Ana Parks, Recreation and Community Services Department for comment on possible impacts
to services due to the proposed project. No feedback regarding the project was received.
Environmental Evaluation
Would the project result in substantial adverse physical impacts associated with the provision of new
or physically altered governmental facilities, need for new or physically altered governmental
facilities, the construction of which could cause significant environmental impacts, in order to
maintain acceptable service ratios, response times or other performance objectives for any of the
public services:
a) Fire protection?
Less than significant impact. The OCFA serves the City of Santa Ana and there are 10 fire stations
within the City. The two nearest stations are Station No. 73—located approximately 0.22 miles south
of the project at 419 South Franklin Street, and Station No. 75—located approximately 1.53 miles
from the project site to the east at 120 West Walnut Street. The proposed project consists of the
construction of a new 7‐Eleven convenience store and fuel station canopy. The project would not
result in a population increase. It is not anticipated that the OCFA response times to the project site
or surrounding vicinity will be affected, however current response times within the City is 8 minutes
39 seconds, which is above the target City response times of 5 minutes (OCFA 2014). As such, prior
to approval, the project’s design would be subject to compliance with the requirements in the
California Building Standards Commission 2016 California Fire Code. The project plans would be
reviewed and approved by the Santa Ana Building and Safety Division and the OCFA, which would
ensure adequate emergency access, fire hydrant availability, and compliance with all applicable
codes and standards. Compliance with the City’s permit process and City of Santa Ana Municipal
Code requirements would ensure that project implementation would result in a less than significant
impact to fire protection services.
b) Police protection?
Less than significant impact. The SAPD provides police services to the project area. The main SAPD
building is located approximately 0.94 mile northeast from the project site at 60 Civic Center Plaza.
The proposed project would not require the construction of new SAPD facilities or expansion of
existing facilities to accommodate the project. Project implementation is not anticipated to increase
SAPD response times to the project site or surrounding vicinity. In addition, the project plans would
be reviewed and approved by the Santa Ana Building and Safety Division and SAPD, which would
ensure that adequate safety and crime prevention measures are provided. Compliance with the
City’s discretionary review process would ensure that project implementation would result in a less
than significant impact to police services.

c) Schools?
No impact. The schools nearest the project area are REACH Academy, located at 1512 West Santa Ana
Blvd. approximately 0.37 mile northeast and Abraham Lincoln Elementary School located
approximately 0.38 mile southwest of the project site. The proposed project would construct a new 7‐
Eleven convenience store and fuel station canopy. It is not anticipated that the project would increase
the population or demand for school services in the City; therefore, no impacts would occur.
d) Parks?
No impact. According to the City’s General Plan Open Space, Parks and Recreation Element, Santa
Ana has approximately 400 acres of public park and recreation facilities and the City strives to
maintain approximately 2 acres of open space for each 1,000 residents. Currently, the City operates
38 parks and recreational facilities within the City as well as playgrounds at several schools. As stated
above, the proposed project is for the construction of a new 7‐Eleven Convenience Store and fuel
station canopy. The implementation of the project would not increase population or demand for
park services in the City; therefore, no impact would occur.
e) Other public facilities?
No impact. The City operates two libraries. The Main Library is located at 26 Civic Center Plaza, and
the Newhope Library is located at 122 North Newhope Street. The population would not increase
because of the proposed project, and, therefore, no impacts would occur.
Mitigation Measures

Environmental Evaluation
a) Would the project increase the use of existing neighborhood and regional parks or other
recreational facilities such that substantial physical deterioration of the facility would occur or be

No impact. According to the City General Plan Open Space, Parks and Recreation Element, Santa Ana
has approximately 400 acres of public park and recreation facilities and the City strives to maintain
approximately 2 acres of open space for each 1,000 residents (City of Santa Ana, 1982). Currently,
the City operates 47 parks and recreational facilities within the City as well as playgrounds at several
schools (City of Santa Ana 2019). The proposed project consists of the construction of a new 7‐
Eleven convenience store and fuel station canopy with associated parking lot. Therefore, the
proposed project is not a residential use and implementation of the project would not increase the
use of existing neighborhood and regional parks or other recreational facilities such that substantial
physical deterioration of the facility would occur or be accelerated.
b) Does the project include recreational facilities or require the construction or expansion of
recreational facilities, which might have an adverse physical effect on the environment?
No impact. The proposed project consists of the construction of a new 7‐Eleven convenience store
and fuel station canopy with associated parking lot. The project is not anticipated to have growth
inducing impacts, as discussed above. There are no plans to construct recreational facilities for the
project; thus, no impacts would occur.

Environmental Setting
A Traffic Impact Analysis (TIA) was prepared for the project by RK Engineering Group, Inc. dated
September 4, 2018, and is included in this IS/MND as Appendix H.
The traffic analysis evaluates the existing weekday peak‐hour operating conditions at six key study
intersections within the project vicinity, estimates the trip generation potential of the proposed
project, and superimposes the project‐related traffic volumes on the circulation system as it
currently exists. In addition, the analysis forecasts future weekday operating conditions (based on
approved and reasonably foreseeable cumulative projects) with and without the proposed project,
and, if necessary, identifies appropriate intersection improvements/mitigation measures. The
weekday peak‐hours evaluated consist of 1 hour between 7:00 a.m. to 9:00 a.m. (referred to as the
AM peak‐hour) and 1 hour between 4:00 p.m. to 6:00 p.m. (referred to as the PM peak‐hour). The
traffic report is intended to satisfy the traffic impact requirements of the City of Santa Ana and
Orange County.
This traffic report analyzes existing and future weekday peak‐hour traffic conditions for a future
(year 2020) traffic setting upon completion of the proposed project. Peak‐hour traffic forecasts for
the year 2020 have been projected by increasing existing traffic volumes by an annual growth rate of
2 percent (to account for 2 years of annual growth at 1 percent) and adding traffic volumes
generated by cumulative projects known to the City of Santa Ana and RK Engineering Group at the
time the study was prepared.

Project Description
The proposed project is located at 1904 West First Street and is bound by West First Street to the
north, a vacant parcel to the south, auto repair uses to the west, and Daisy Avenue to the east. The
project currently contains an existing vacant restaurant, which is planned to be displaced by the
proposed project. Although the project proposes to construct a four vehicle‐fueling‐position gas
station, the traffic analysis evaluates the traffic impacts associated with construction of an eight
vehicle‐fueling‐position gas station. Hence, the traffic analysis is considered conservative. The
project is projected for completion by year 2020 and has been evaluated in a single phase.
Site Access
Vehicular access to the site will be provided via three proposed unsignalized driveways, one along
West First Street, and two along Daisy Avenue.
City of Santa Ana LOS and Significance Criteria
The City of Santa Ana utilizes level of service (LOS) metrics for analyzing potentially significant
impacts. The City of Santa Ana target for peak‐hour intersection operation is LOS D or better. For
intersections located within areas of the City designated Major Development Areas, LOS E or better
is considered acceptable. This project is not in a major development area. For signalized
intersections that have an existing LOS of F, a project increase of 1 percent of capacity is considered
significant. Any intersection operating at LOS E or LOS F will be considered deficient and mitigation
measures will need to be identified to achieve acceptable LOS.

LOS Methodology
The methodology used to assess the operation of the signalized study area intersections within the
jurisdiction of City of Santa Ana is Intersection Capacity Utilization (ICU). Study area intersections
that are stop sign controlled have been analyzed using the Highway Capacity Manual methodology.
Existing Conditions
Table 16 summarizes the existing peak‐hour service level calculations for the six study area
intersections based on existing traffic volumes and current street geometry. Review of Table 16
indicates that all of the six study intersections currently operate at an acceptable level of service
during the AM and PM peak‐hours.

Project Trip Generation
Trip generation represents the amount of traffic that is attracted and produced by a development.
The trip generation for the project is based upon the specific land uses that have been planned for
the development. As previously noted, the proposed project consists of constructing a four vehicle‐
fueling‐position gas station, the traffic analysis evaluates the traffic impacts associated with
construction of an eight vehicle‐fueling‐position gas station. Hence, the traffic analysis is considered
conservative.
Trip generation rates for the proposed project are shown in Table 17 and are based on the Institute
of Transportation Engineers (ITE) Trip Generation Manual, 10th Edition, 2017. This publication
provides a comprehensive evaluation of trip generation rates for a variety of land uses.

Project Trip Distribution and Assignment
Trip distribution represents the directional orientation of traffic to and from the project site. Trip
distribution is heavily influenced by the geographical location of the site, the location of residential,
employment, and recreational opportunities, and the proximity to the regional freeway system. The
directional orientation of traffic was determined by evaluating existing and proposed land uses, and
highways within the community.
Trip distribution patterns for this study have been based upon near‐term conditions from those
highway facilities that are either in place or will be contemplated over the next few years, which
represents the completion and occupancy for the proposed development.
The project trip distribution assumptions were provided to City of Santa Ana staff for review and
approval prior to preparation of the traffic study.

Queueing Analysis
As requested by City staff, a Highway Capacity Manual 95th percentile vehicular queuing analysis has
been prepared for all turning movements at each project access driveway and the intersection of
Daisy Avenue at West First Street.
The vehicular queue analysis has been prepared for the AM and PM peak‐hours of the Project Opening
Year (2020) With and Without Project scenarios which are the most trip‐intensive scenarios evaluated.

As shown in Table 22, the intersection of Daisy Avenue at West First Street is forecast to experience
the maximum vehicular queue length at the northbound approach, with seven vehicles in queue
during the AM peak hour of the Project Opening Year (2020) With Project analysis scenario. The
remaining approaches are forecast to experience a peak queue of one vehicle during both the AM
and PM peak‐hours of the Project Opening Year (2020) With and Without Project analysis scenarios.
For the project access driveway along West First Street, it is forecast that both the egress and ingress
movements will experience a queue of one vehicle during the peak hours of the Project Opening
Year (2020) With Project analysis scenario.
For project access driveways along Daisy Avenue, it is forecast that all egress movements will
experience a queue of one vehicle and all ingress movements will experience a queue of zero
vehicles during the peak‐hours of the Project Opening Year (2020) With Project analysis scenario.
As a result of the low queue lengths, vehicular conflicts at each project access driveway and at the
intersection of Daisy Avenue at West First Street are expected to be minimal.
Environmental Evaluation
Would the project:
a) Conflict with a program plan, ordinance or policy addressing the circulation system, including
transit, roadway, bicycle and pedestrian facilities?
Less than significant impact with mitigation incorporated. As stated above, the intersection of Daisy
Avenue at West First Street is anticipated to operate at an unacceptable LOS under future traffic
conditions. To reduce vehicular conflicts with northbound left turn lane from Daisy Avenue onto
West First Street, MM TRANS‐1 is recommended. MM TRANS‐1 recommends that the project access
driveways along Daisy Avenue be restricted to left‐in, right‐in, right‐out only. The change in the 95th
percentile vehicular queues at each project driveway are expected to be minimal. As a result, the
proposed project can be accommodated with the implementation of MM TRANS‐1. As such, impacts
would be less than significant with mitigation incorporated.

b) Would the project conflict or be inconsistent with CEQA Guidelines Section 15064.3, subdivision
(b)?
Less than significant impact. Land use projects within one‐half mile of a major transit stop or a stop
along a high‐quality transit corridor should be presumed to have a less than significant
transportation impact. “Major transit stop” means a site containing an existing rail transit station, a
ferry terminal served by either a bus or rail transit service, or the intersection of two or more major
bus routes with a frequency of service interval of 15 minutes or less during the morning and
afternoon peak commute periods. A “high‐quality transit corridor” is a corridor with fixed route bus
service with service intervals that do not exceed 15 minutes during peak commute hours. (Public
Resource Code [PRC] §§ 21064.3, 21155.) OCTA, Los Angeles Transit Authority (Metro) and Anaheim
Resort Transportation operate bus lines within the project area. According to the OCTA, transit
Routes 64, 64Xpress, and 150A currently serve the project area. There are 14 existing bus stops
within a 0.5‐mile radius of the project site. As such, the proposed project will have a less than
significant impact on VMT.
c) Substantially increase hazards due to a geometric design feature (e.g., sharp curves or dangerous
intersections) or incompatible uses (e.g., farm equipment)?
Less than significant impact. As previously discussed, the TIA includes queuing analysis for all
turning movements at each project access driveway and the intersection of Daisy Avenue at West
First Street. Although a traffic signal is warranted at the intersection of Daisy Avenue at West First
street, installation of a traffic signal is not recommended due to the close proximity of the adjacent
signalized intersections of Townsend Street at West First Street and Raitt Street at West First Street.
Traffic signals located in close proximity to each other may disrupt traffic flow and cause stacking
issues. The change in the 95th percentile vehicular queues at each project driveway are expected to
be minimal. As a result of the low queue lengths, vehicular conflicts at each project access driveway
and at the intersection of Daisy Avenue at West First Street are expected to be minimal. Impacts
would be less than significant.
d) Result in inadequate emergency access?
Less than significant with mitigation incorporated. The project will provide adequate emergency
access in all phases of development. In addition, the project applicant will comply with applicable
Fire Department and Division of Building and Safety regulations relating to emergency access.
Vehicular access for the proposed project will be provided via three proposed unsignalized
driveways, one along West First Street and two along Daisy Avenue. Implementation of MM TRANS‐2
will ensure that the project’s impact on emergency access would be less than significant.
Mitigation Measures
MM TRANS‐1 The project access driveways along Daisy Avenue shall be restricted to left‐in, right‐
in, right‐out only.

FirstCarbon Solutions 115 Y:\Publications\Client (PN‐JN)\0327\03270041\ISMND\03270041 City of Santa Ana 7‐Eleven Store ISMND.docx
MM TRANS‐2 Ensure adequate sight distance is provided at each project access location per the
City of Santa Ana. Sight distance at all project access points should be reviewed with
respect to City of Santa sight distance standards at the time of preparation of final
grading, landscape, and street improvement plans.
Provide appropriate signage and pavement markings at the project access
driveways, including stop bars and stop signs and restrict project access through
clear signage and other means.
To minimize vehicular conflicts at the northern Project Access Driveway on Daisy
Avenue, left‐turn movements out of the site should be restricted at this location.
Install “No Left Turn” signage and “Right Turn Only” striping at northern project
access driveway on Daisy Avenue for vehicles exiting the site.

b) Have sufficient water supplies available to serve the project and reasonably foreseeable future development during normal, dry and multiple dry years?
c) Result in a determination by the wastewater treatment provider which serves or may serve the project that it has adequate capacity to serve the project’s projected demand in addition to the provider’s existing commitments?
d) Generate solid waste in excess of State or local standards, or in excess of the capacity of local infrastructure, or otherwise impair the attainment of solid waste reduction goals?
e) Comply with federal, State, and local management and reduction statutes and regulations related to solid waste?
Environmental Setting
According to the Santa Ana General Plan Land Use Element, domestic water services in the City of
Santa Ana are mainly provided by the Santa Ana Municipal Utility Services. Two small water
companies serve a portion of the City through groundwater wells. On average, the Santa Ana Water
Department delivers 43 million gallons of water daily to some 48,000 customers. This service is
provided through 20 groundwater wells, 444 miles of water mains, and eight storage tanks or
reservoirs with a combined capacity of 45 million gallons. Santa Ana is a member city of the
Metropolitan Water District of Southern California (Metropolitan), which receives water from the
State Water Project emanating from sources of the Sierra Nevada mountain range, and the Colorado
River via Lake Havasu.
According to the 2017 Santa Ana Water Quality Report, Santa Ana pumps approximately 70 percent
of its water supply from 20 city‐owned wells, and purchases 30 percent of its supply from
City of Santa Ana 7‐Eleven Convenience Store and Service Station Project Environmental Checklist and Initial Study/Mitigated Negative Declaration Environmental Evaluation
FirstCarbon Solutions 117 Y:\Publications\Client (PN‐JN)\0327\03270041\ISMND\03270041 City of Santa Ana 7‐Eleven Store ISMND.docx
Metropolitan. The City’s wells can provide a maximum of 71 million gallons per day (mgd), and
Metropolitan can provide 65 mgd. Approximately 500 miles of local sewer lines are maintained by
the City of Santa Ana, with sewer trunks owned and maintained by the Orange County Sanitation
District (OCSD). The OCSD’s Green Acres Project allows for the reuse of reclaimed wastewater for
industrial and landscape irrigation uses. Waste Management provides solid waste collection services
to the City of Santa Ana. Solid waste is transported by truck to the Sunset Environmental Service
Transfer Station in Irvine and the CVT Transfer Station in Anaheim. The City of Santa Ana has adopted
a Source Reduction and Recycling Element (SRRE) in 1992. This plan calls for recycling, composting,
special waste disposal, and education and public information programs.
Environmental Evaluation
Would the project:
a) Require or result in the relocation or construction of new or expanded water, wastewater
treatment or storm water drainage, electric power, natural gas, or telecommunications facilities,
the construction or relocation of which could cause significant environmental effects?
Less than significant impact. The City of Santa Ana 2015 UWMP determined that the City is
expected to fully meet demands for the next 3 years. In addition, this project is located in an
urbanized area that is currently served by the Santa Ana Municipal Utility Services and accounted for
in the Water Supply Allocation Plan as described in Section 5.2.2 of the Santa Ana 2015 UWMP. The
project would not create the need for new water facilities or result in insufficient water supply. Thus,
there would no need to construct new or expand existing water treatment facilities. Therefore,
impacts related to need for relocation or construction of new or expanded water supply facilities
would be less than significant.
Wastewater from the project would mainly consist of effluent typical of commercial uses. None of
the proposed uses would generate atypical wastewater such as industrial or agricultural effluent. All
wastewater generated by the project is expected to be domestic sewage. The convenience store
would contain small quantities of household hazardous materials such as cleaning solvents, but
these quantities would not be sufficient to exceed treatment requirements. Additionally, the project
would be required to comply with all applicable regulations and standards, including the NPDES
permit requirements and RWQCB standards. The City of Santa Ana currently has sewage facilities
available to serve the proposed project. The increase in wastewater generation would result in an
incremental increase in the demand for wastewater conveyance and treatment facilities. The
project’s wastewater would be carried off‐site through connections with existing sewer system lines
surrounding the project site.
According to the project’s WQMP (Fielder Group 2018, Appendix F), the project site currently
contains a total of 17,237 square feet of impervious surface area and 99 square feet of pervious
surface area. The project would result in the development of 14,360 square feet of impervious
surface area and 2,795 square feet of pervious surface area. The on‐site stormwater will be
mitigated by an underground infiltration system. Existing draining and topography will be maintained

and continue to sheet flow southeasterly. As such, the project would not require or result in the
construction of new stormwater drainage facilities or the expansion of existing facilities.
SCE currently provides the project area with electricity and will not require new or expanded
facilities to service the project. SoCalGas has currently provides natural gas to the project area and
will not require new or expanded facilities to service the project. The project would not need new
telecommunications facilities because it is located in an urban area that already contains sufficient
telecommunications facilities. The installation of the UST is not anticipated to impede any existing
facilities. Therefore, impacts related to need for relocation or construction of new or expanded
relocation or construction of new or expanded water, wastewater treatment or stormwater
drainage, electric power, natural gas, or telecommunications facilities would be less than significant.
b) Have sufficient water supplies available to serve the project and reasonably foreseeable future
development during normal, dry and multiple dry years?
Less than significant impact. The project would require water for the daily needs of customers as
well as for landscaping, maintenance, and the operation of the facility. As mentioned previously, the
City of Santa Ana 2015 UWMP determined that the water supplies are projected to meet full‐service
demands; Metropolitan’s 2015 UWMP find that Metropolitan is able to meet, full‐service demands
of its member agencies starting 2020 through 2040 during normal years, single dry year, and
multiple dry years. In addition, this project is located in an urbanized area that is currently served by
the Santa Ana Municipal Utility Services Water and accounted for in the Water Supply Allocation
Plan as described in Section 5.2.2 of the Santa Ana 2015 UWMP. Therefore, impacts related to
sufficient water supply availability would be less than significant.
c) Result in a determination by the wastewater treatment provider which serves or may serve the
project that it has adequate capacity to serve the project’s projected demand in addition to the
provider’s existing commitments?
Less than significant impact. The City does not own or operate wastewater treatment facilities and
sends all collected wastewater to OCSD for treatment and disposal. The City operates and maintains
the local sewer system consisting of over 390 miles of pipeline, 7,630 manholes, and two lift stations
that connect to OCSD’s trunk system to convey wastewater to OCSD’s treatment plants. Wastewater
generated by the proposed project would be conveyed to existing OCSD operated sewer lines. As
wastewater generation rates are not listed in the City of Santa Ana’s UWMP, wastewater generation
rates from the City of Los Angeles’ CEQA Threshold Guidelines were used to estimate the projected
wastewater generated by the proposed project. The proposed project is anticipated to generate a
net increase of approximately 430 gallons per day (gpd) of wastewater. This increase represents a
nominal percent of the 24 million gpd remaining capacity at the OCSD Reclamation Plant No. 2.
Therefore, the OCSD has adequate remaining capacity to serve the proposed project. Thus, impacts
related to wastewater treatment capacity would be less than significant.

infrastructure, or otherwise impair the attainment of solid waste reduction goals?
Less than significant impact. During the project’s construction phase, the existing vacant restaurant
would be demolished, which would in turn result in construction‐related solid waste. Waste
Management has contracted with the City to provide solid waste collection services to the City of
Santa Ana. Solid waste is transported by truck to the Sunset Environmental Service Transfer Station
in Irvine and the CVT Transfer Station in Anaheim, with final transfer to the Frank R. Bowerman
Landfill in Irvine. The Frank R. Bowerman Landfill has a total remaining capacity of 205 million cubic
yards for solid waste and an allowance of 11,500 tons throughput per day. Using estimated solid
waste generation rates provided by the California Department of Resources Recycling and Recovery
(CalRecycle), the proposed project is projected to generate approximately 86.68 pounds of solid
waste daily at full buildout. The project would not result in a significant increase in solid waste
generated on‐site, as there will only be an incremental increase in solid waste that would be
transported off‐site. Waste Management will service the site, pick‐up the bin at the on‐site trash
enclosures. Less than significant impacts would occur.
e) Comply with federal, state, and local management and reduction statutes and regulations
related to solid waste?
Less than significant impact. In 1989, the Legislature adopted the California Integrated Waste
Management Act of 1989 (Assembly Bill [AB] 939), in order to “reduce, recycle, and re‐use solid
waste generated in the state to the maximum extent feasible.” AB 939 established a waste
management hierarchy: Source Reduction, Recycling, Composting, Transformation, and Disposal. The
law also required that each county prepare a new Integrated Waste Management Plan and each city
prepare an SRRE by July 1, 1991. The SRRE is required to identify how each jurisdiction will meet the
mandatory State waste diversion goal of 50 percent by the year 2000. The Act mandated that
California’s 450 jurisdictions (cities, counties, and regional waste management compacts) implement
waste management programs aimed at a 25 percent diversion rate by 1995 and a 50 percent
diversion rate by 2000. If the 50 percent goal was not met by the end of 2000, the jurisdiction was
required to submit a petition for a goal extension to CalRecycle.
Senate Bill (SB) 2202 made a number of changes to the municipal solid waste diversion requirements
under AB 939. These changes included a revision to the statutory requirement for 50 percent
diversion of solid waste to clarify that local governments shall continue to divert 50 percent of all
solid waste on and after January 1, 2000.
SB 1016 introduced a per capita disposal measurement system that measures the 50 percent
diversion requirement using a disposal measurement equivalent. The Bill repealed the State Water
Board’s 2‐year process, requiring instead that the State Water Board make a finding whether each
jurisdiction was in compliance with the Act’s diversion requirements for calendar year 2006 and to
determine compliance for the 2007 calendar year and beyond, based on the jurisdiction’s change in
its per capita disposal rate. The State Water Board is required to review a jurisdiction’s compliance
with those diversion requirements in accordance with a specified schedule, which is conditioned

Y:\Publications\Client (PN‐JN)\0327\03270041\ISMND\03270041 City of Santa Ana 7‐Eleven Store ISMND.docx
upon the State Water Board finding that the jurisdiction complies with those requirements or has
implemented its source reduction and recycling element and household hazardous waste element.
The Bill requires the State Water Board to issue an order of compliance if the State Water Board
finds that the jurisdiction has failed to make a good faith effort to implement its source reduction
and recycling element or its household hazardous waste element, pursuant to a specified procedure.
The per capita disposal rate is a jurisdiction‐specific index, which is used as one of several “factors”
in determining a jurisdiction’s compliance with the intent of AB 939, and allows CalRecycle and
jurisdictions to set their primary focus on successful implementation of diversion programs. Meeting
the disposal rate targets is not necessarily an indication of compliance. CalRecycle reports that Santa
Ana’s Disposal Rate Targets for Reporting Year 2011 are 4.8 pounds per day per resident and 11.3
pounds per day per employee.
The proposed project is expected to be serviced by Waste Management. Any changes in locations for
trash carts and bulky pickup, sufficient clearance, and appropriate routing for trucks would be
coordinated by the City and Waste Management.
Participation in the City’s recycling programs during project construction and operation, including
CalRecycle’s requirements, would ensure that the project would not conflict with federal, State, and
local statutes and regulations related to solid waste. Furthermore, the project would meet or exceed
standards set forth in California Green Building Standards Code (CALGreen) as well as Title 24. Less
than significant impacts would occur.

Environmental Evaluation
If located in or near State responsibility areas or lands classified as Very High Fire Hazard Severity
Zones would the project:
a) Substantially impair an adopted emergency response plan or emergency evacuation plan?
No impact. According to CAL FIRE, Fire Hazard Severity Zones Map, the project site is not located
within or near State responsibility areas or lands classified as a Very High Fire Hazard Severity Zone;
therefore there are no impacts. The proposed project does not possess characteristics that would
physically impair or otherwise interfere with emergency response as outlined in the OCFA Standards
of Cover and Deployment Plan 2014 or with emergency evacuations in the project vicinity (OCFA
2014). As such, no impacts would occur.
b) Due to slope, prevailing winds, and other factors, exacerbate wildfire risks, and thereby expose
project occupants to, pollutant concentrations from a wildfire or the uncontrolled spread of a
wildfire?
No impact. According to the CAL FIRE Fire Hazard Severity Zones Map, the project site is not located
within a State responsibility areas or lands classified as a Very High Fire Hazard Severity Zone;

therefore, there are no impacts. The proposed project is located in an urban built up area and is
surrounded by urban development on all sides. Additionally, prior to approval, the project’s design
would be subject to compliance with the requirements in the California Building Standards
Commission 2016 California Fire Code. The project plans would be reviewed and approved by the
Santa Ana Building and Safety Division and the OCFA, which would ensure adequate compliance with
the City’s permit process and City of Santa Ana Municipal Code requirements. This would ensure
that the project would not expose occupants to pollutant concentrations risks or uncontrolled
spread due to slope, prevailing winds, wildland fires and other factors. Therefore, no impacts would
occur.
c) Require the installation or maintenance of associated infrastructure (such as roads, fuel breaks,
emergency water sources, power lines or other utilities) that may exacerbate fire risk or that may
result in temporary or ongoing impacts to the environment?
Less than significant impact. According to the CAL FIRE Fire Hazard Severity Zones Map, the project
site is not located within or near state responsibility areas or lands classified as a Very High Fire
Hazard Severity Zone; therefore, there are no impacts. The proposed project would construct a new
7‐Eleven convenience store and fuel station canopy. Impacts related to installation or maintenance
of infrastructure (such as roads, fuel breaks, emergency water sources, electrical power lines, or
natural gas lines) that may exacerbate fire risk are limited to operational impacts. No respective
construction impacts related to infrastructure that exacerbates fire risk would occur.
The proposed project would include adequate emergency access via three proposed unsignalized
driveways; one along West First Street and two along Daisy Avenue. The project site is an urban area
surrounded by existing roadways. The project would not require the installation of firebreaks,
because it is in an urban area surrounded by existing development with little natural vegetation. The
project would not require emergency water sources, because potable water is currently provided by
the Santa Ana Water Department, which has adequate water supplies available to serve the project
and future development during normal, dry, and multiple dry years. Therefore, impacts related to
infrastructure that exacerbates fire risk would be less than significant.
d) Expose people or structures to significant risks, including downslope or downstream flooding or
landslides, as a result of runoff, post‐fire slope instability, or drainage changes?
No impact. According to the CAL FIRE Fire Hazard Severity Zones Map, the project site is not located
within or near State responsibility areas or lands classified as a Very High Fire Hazard Severity Zone;
therefore, there are no impacts. Further, the proposed project is comprised of relatively flat parcels
located in an urbanized area surrounded by commercial, residential and light industrial uses. Federal
Emergency Management Agency (FEMA) Flood Insurance Rate Map (FIRM) No. 06059C0257J,
indicates the project site is located in Zone X: a zone that corresponds to areas outside of the 500‐
year flood or areas protected from the 100‐year flood by levees. In other words, Zone X is defined as
areas with a 0.2 percent annual chance of flood (i.e., a 500‐year flood hazard area). These conditions
preclude the possibility of subjecting people or structures to significant risks related to post‐fire slop

a) Does the project have the potential to substantially degrade the quality of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self‐sustaining levels, threaten to eliminate a plant or animal community, substantially reduce the number or restrict the range of a rare or endangered plant or animal, or eliminate important examples of the major periods of California history or prehistory?
b) Does the project have impacts that are individually limited, but cumulatively considerable? (“Cumulatively considerable” means that the incremental effects of a project are considerable when viewed in connection with the effects of past projects, the effects of other current projects, and the effects of probable future projects)?
c) Does the project have environmental effects, which will cause substantial adverse effects on human beings, either directly or indirectly?
Environmental Evaluation
a) Does the project have the potential to substantially degrade the quality of the environment,
substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to
drop below self‐sustaining levels, threaten to eliminate a plant or animal community,
substantially reduce the number or restrict the range of a rare or endangered plant or animal, or
eliminate important examples of the major periods of California history or prehistory?
Less than significant impact with mitigation incorporated. With implementation of MM BIO‐1a and
MM BIO‐1b, and SC 2.5‐1 and SC 2.5‐2, the proposed project would not substantially degrade the
quality of the environment, substantially reduce the habitat of fish or wildlife species, cause a fish or
wildlife population to drop below self‐sustaining levels, threaten to eliminate a plant or animal
community, or reduce the number or restrict the range of a rare or endangered plant or animal, or
eliminate important examples of the major periods of California history or prehistory.
MM BIO‐1a and MM BIO‐1b, and SC 2.5‐1 to SC 2.5‐2 would protect the potential biological integrity
of the site from potential construction impacts.

b) Does the project have impacts that are individually limited, but cumulatively considerable?
(“Cumulatively considerable” means that the incremental effects of a project are considerable
when viewed in connection with the effects of past projects, the effects of other current
projects, and the effects of probable future projects)?
Less than significant impact with mitigation incorporated. The project would result in potentially
significant project‐level impacts related to biological resources, cultural resources, geology, hazards
and hazardous materials, noise and transportation (design hazards). However, MM BIO‐1a, MM BIO‐
1b, SC 2.5‐1 and SC 2.5‐2, MM GEO‐1 through MM GEO‐7, MM HAZ‐1, MM NOI‐1, and MM TRANS‐1
and MM TRANS‐2 shall be implemented as part of the project. The mitigation measures will,
amongst other things, remove potential hazardous material release from past projects, reduce noise
impacts from the proposed project, and reduce transportation impacts to the surrounding area. The
mitigation measures will reduce each impact to a level of less than significant.
All other impacts of the project were determined either to have no impact or to be less than
significant without the need for mitigation. Cumulatively, the project would not result in any
significant impacts that would substantially combine with impacts of other current or probable
future impacts. Therefore, the project, in conjunction with other future development projects,
would not result in any cumulatively considerable impacts.
c) Does the project have environmental effects, which will cause substantial adverse effects on
human beings, either directly or indirectly?
Less than significant impact with mitigation incorporated. The previous sections of this IS/MND
reviewed the project’s potential impacts related to biological resources, cultural resources, geology,
hazards and hazardous materials, and noise, among other environmental issue areas. As concluded
in these previous discussions, the project would result in less than significant impacts with
implementation of MM BIO‐1a, MM BIO‐1b, SC 2.5‐1 and SC 2.5‐2, MM GEO‐1 through MM GEO‐7,
MM HAZ‐1, MM NOI‐1, and MM TRANS‐1 and MM TRANS‐2. Therefore, with implementation of the
specified mitigation and standard BMPs and conditions of approval, the project would cause less
than significant adverse effects on human beings.
Mitigation Measures
Implement MM BIO‐1a, MM BIO‐1b, SC 2.5‐1 and SC 2.5‐2, MM GEO‐1 through MM GEO‐7, MM
HAZ‐1, MM NOI‐1, and MM TRANS‐1 and MM TRANS‐2.
