Water and Wastewater
Water
The Los Angeles Department of Water and Power (LADWP) currently supplies water to the
existing Yamashiro site. The LADWP acquires its water supply from three sources including, the
Los Angeles Aqueduct (LAA), the Metropolitan Water District of Southern California (MWD)
and local ground water.
It is said that Los Angeles Aqueduct supplies half of LA City’s water. The Metropolitan Water
District of Southern California is the largest wholesaler of water in California and on an average
provides close to 35 percent of the state’s water supply. MWD gets its water from Colorado River
and Northern California Bay Delta.
In 2009 to 2011, the LADWP had an available water supply of about 550000 acre feet with
approximately 14 percent coming from the local groundwater supply. Groundwater level in the
city I maintained through recharge basins.
Construction Impacts
During construction, portions of the existing landscaping would be removed and the existing
mountain will have modifications as a whole for development. As a result the underlying soils
would be exposed making it more permeable and susceptible for conveyance into nearby storm
drains. This permeability will not have a greater impact on the existing drainage system. The
redevelopment of this project would require earthwork activities that includes grading and
excavation of the site. There is a chance of exposure of the soil for time leading to corrosion. To
avoid this situation, it would be better to get a grading permit from the Department of Building
and Safety. This would include the requirements and standards designed to limit potential impact
associated with erosion to a permitted level.
Currently the area to be redeveloped is a mix of land uses that has a restaurant and surrounded by
beautiful landscape. Based on the water consumption analysis prepared by the LADWP, the water
consumption is close to 5000 gallons per day (GPD) seven days a week. The development of this
project will include the removal of the existing land uses, within the area prior to the construction
of the project. The consumption of water from existing land uses will be subtracted from the
Project’s contribution as a means of accurately calculating the net increase as a result of the Project.
The restaurant services and water for irrigation and maintenance of the landscape is provided by
an 8” water main. The existing water lines are assumed to be in a deteriorated condition due to
their age. Speaking to the representatives and the managers at Yamashiro, we got to know that no
development work has been done from the time it was constructed. Based on the LADWP Service
Advisory Report, the existing line has a fire flow of approximately 1700 GPM. No record of the
location and route of the existing domestic water line has been discovered for this project so it has
not been mapped beyond the two known ends of the water line. Thus the very first thing that has

to be done is the up gradation of the water system with progression of the planned development
phases.
Existing landscaping is irrigated. But the construction work and the redevelopment work will harm
the existing irrigation and landscaping which has to be looked into. Furthermore, there would be
on site water activities to reduce the airborne dust during the construction process which could
contribute to the pollutant loading in the storm water runoff. The NPDES (National Pollutant
Discharge Elimination System) general permits will be required which would also specify the
erosion control measures to be used during construction activities.
Hydrants fronting the site will be used to fill water tanks for construction uses. Water will be used
during the construction, excavation and grading activities. It is estimated that 500,000 to 800,000
gallons of water will be used during the construction process.
As the site is one of the greatest historic places and the very goal is to increase the parking so as
to attract more crowd, better firefighting needs have to be developed as the existing ones will be
damaged during the construction phase.
Operations Impacts
The proposed project would result in an increase in an impervious or impenetrable surface. The
easy passage of water will be a little difficult. With the proposed improvements, drainage would
follow patterns that would be similar to existing drainage patterns, with the exception of increased
impervious areas resulting from new additions to the site and an increase in the surface parking
areas.
The proposed Project’s approximate 5 percent increase in impervious area would result in a post-
development storm water runoff flow of 23.30 cubic feet per second (cfs), which represents a 1
percent decrease in flow when compared to existing conditions of 23.62 cfs. Therefore, no increase
in flows during a 50-year storm condition would occur and Standard Urban Storm water Mitigation
Plan (SUSMP) requirements regarding peak flows would be met. Thus, impacts associated with
drainage would be less than significant.
As the proposed uses would be the same, the Project would not generate any new sources of
polluted runoff. In accordance with the Standard Urban Storm water Mitigation Plan, the existing
site would be required to implement Best Management Practices during this operational phase to
reduce the discharge of polluted runoff from the site. Once the pollutants are present in a water
body altering its physical makeup and habitat, it is much more difficult and expensive to restore
it. Therefore, the usage of Best Management Practices prevents the damage. Storm water pollution
has two main components:
The increased volume and rate of runoff from water resistant surfaces, such as roads and
parking lots, and
The amount of pollutants in the runoff.

In turn, effective management of storm water runoff offers a multitude of benefits:
protection of wetlands and ecosystems,
improved water quality of streams, rivers and other water bodies,
protection of water resources,
protection of public health, and
flood control
The final selection of BMPs would be completed through coordination with the City of Los
Angeles. With compliance with National Pollutant Discharge Elimination System (NPDES)
requirements, impacts associated with water quality would be less than significant.
Other project related activities could potentially increase the volume of storm water runoff and
contribute to pollutant loading, resulting in cumulative impacts to hydrology and surface water
quality. However, as with the proposed Project, all of the related projects would also be subject to
State NPDES permit requirements for both construction and operation. Each project would be
required to develop a Storm Water Pollution Prevention Plan (SWPPP) and would be evaluated
individually to determine appropriate Management practices and treatment measures to avoid
impacts to surface water quality. In addition, the City of Los Angeles Department of Public Works
reviews all construction projects on a case-by-case basis to ensure that sufficient local and regional
drainage capacity is available. Thus, cumulative impacts to hydrology and surface water quality
would be less than significant.
Mitigation Measures – Water
Although Project impacts are less than significant, the following mitigation measures would help
to further reduce impacts:
The future development plan will utilize the latest code required water conserving fixtures for all
fixture installations. This will include new installations and replacements. By replacing existing
low efficiency fixtures and with new low-flow type fixtures there will be a reduction in calculated
demand from the municipal water supply. As each phase of this plan is implemented, the entire
existing water system will be replaced in stages as well. The end result will be an entirely new
water system, both domestic and fire service, to meet the increased demands and serviceability.
In terms of landscape and irrigation, the proposed development site will use automatic sprinkler
systems for the landscape irrigation. They can be adjusted on a seasonal basis to operate during
hours where water loss due to evaporation is less (as in periods from November to February). If
possible, provision will be provided for water reclamation. The reclaimed water wherever feasible
shall be used to irrigate the landscaped areas in and around our site. Further care should be taken
that the project complies with all sections of the City of Los Angeles’s Water Conservation
Ordinance (No: 166080). This Ordinance No. 166,080 is the Water Conservation plan for the City
of Los Angeles.

The proposed Project shall use lower-volume water faucets and water saving shower taps in all
construction. The project will also use plumbing fixtures that reduce potential water loss from
leakage due to excessive washers. Installation of low flow water fixtures is also a feasible plan.
In terms of fire and safety, new fire hydrants are to be installed on-site to supplement two existing
public hydrants fronting the site. As each phase of the plan is proceeded new hydrants will be
added in each stage. Based on the design and plumbing, the existing municipal water supply has
insufficient pressure to supply new hydrants due to low available pressure and the site elevation.
Care is taken that the existing and proposed planting have been selected as either a native or climate
adapted species that has low watering requirements and are drought tolerant. The irrigation system
should be modelled with hydro zones to most effectively response to specific location of site and
maximize water efficiencies. A soil test of the existing conditions and management plan will
improve the soil conditions and allocate the appropriate amendments within planting areas. Storm
water run‐off and erosion is minimized through plantings, planter walls, and forms of terracing.
The underlying site geology is mainly impervious bedrock formations with little to no significant
percolation or infiltration to affect any groundwater sources. There are no wells or plans to draw
groundwater for use of the project. The master plan project will fall under Storm water
Management requirements for storm water mitigation measures, as dictated by the State of
California. This will reduce surface runoff pollutants and volumes to mitigate any off-site ground
water impact.
Historic building code State Historical Building Code (SHBC) provides other safety alternatives
which might give out other means of achieving the mitigation and safety in terms of sprinklers
using the historic code
Alternatives
a) Reduced water consumption and recycle and reuse by the reduction in parking space from 300
to 100 – This alternative will significantly bring down the water use during construction phase
from 500,000 to 800,000 to approximately 200,000 to 300,000 and also reduce the storm water
runoff. No project – This alternative yield no environmental impact
b) No project – This alternative yield no environmental impact

Wastewater
The City of Los Angeles Department of Public Works (“LADPW”) provides the wastewater
services for the Project Site. Any wastewater that would be generated by the site would be treated
at the Hyperion Treatment Plant. The Hyperion Treatment plant includes the Tillman Water
Reclamation Plant and the Los Angeles Glendale Water Reclamation Plant. The Hyperion
treatment plant is designed to treat 450 million gallons per day. The average dry water flow is
approximately 360 million gallons per day, which leaves out close to 90 million gallons of
treatment capacity available.
Construction Impacts
Construction of the Project would include all necessary on‐ and off‐site sewer pipe improvements
and connections to adequately connect to the City’s existing sewer system. The development
project would not generate that much sewer flows that would harm or jeopardize the ability of the
treatment plant to operate within its treatment requirements.
The construction phase will involve the generation of a lot of wastewater. Wastewater would be
generated from activities including maintenance, wash down, cleaning of the construction
equipment and general use. Wastewater from construction activities would be collected in onsite
proprietary disposal systems and removed from the site by licensed waste disposal contractors
prior to connection to the Hyperion treatment plant.
Proprietary wastewater collection and holding tanks would be used to collect wastewater from
individual work activities, or work sites during construction. These tanks would be supplied and
operated by the contractors. Domestic wastewater would be managed by the use of onsite
proprietary sanitary units, which would be located close to individual work site areas. During the
dredging and reclamation works, domestic wastewater would be managed on board the dredge
vessels. The vessel storage tanks would be emptied by normal, onshore sanitary disposal facilities.
A licensed waste management company would handle the transport and disposal of all wastewater
from the site during the construction works.
Another important criterion to be kept in mind is that the volume of wastewater generated during
construction would depend on the number of construction workers at the site and the nature of the
construction activities being undertaken. For significant periods of the construction program, up
to 100 construction workers would be on site. With this number of workers, the peak domestic
wastewater volume during construction would be about 12kL per day.
During construction of the project, a negligible amount of wastewater would be generated by
construction staff. If we assume that portable toilets would be provided by a private company, with
the wastewater transported and disposed of off-site. Wastewater generation from construction
activities is not anticipated to cause a measurable increase in wastewater flows at a point where,
and at a time when, a sewer’s capacity is already constrained or that would cause a sewer’s capacity
to become constrained. Additionally, construction is not anticipated to generate wastewater flows
that would substantially or incrementally exceed the future scheduled capacity of any one
Sharanya Ganesh

treatment plant by generating flows greater than those anticipated in the Wastewater Facilities Plan
or General Plan and its elements. Construction of the project would not require or result in the
construction of new wastewater treatment facilities or expansion of existing facilities; or result in
a determination by the City that it has inadequate capacity to serve the project’s projected demand
in addition to existing commitments. Therefore, construction impacts to the local wastewater
conveyance and treatment system would be less than significant.
Operation Impact Conveyance of the wastewater to the Hyperion treatment plant is done by sewer lines that are
maintained by the City of Los Angeles, Department of Public Works. Although the local
infrastructure is in place, the development of this site would require treatment and re-installation
of the 18 inch sewer line. The existing sewer lines have lost their efficiency due to age and they
have not been treated since the initial construction and set up. Any change to the existing sewer
infrastructure would be considered as a part of the development project.
Mitigation Measures - Wastewater:
Impacts related to wastewater treatment would be less than significant and the following mitigation
measures will address the impact to sewer.
For all future development projects within the Project Area, the Agency shall have a sewer
capacity study done. This would specify the wastewater flow from the project and assess
the capacity of the specific sewer lines that would serve the project to ensure the adequate
capacity will be available. This study will be utilized by the Bureau of Engineering as part
of their permitting process to determine whether sewer connection permits can be issued
for new developments.
The Agency shall consult with the Bureau of Engineering and Bureau of Sanitation to
prepare a plan that provides for the upgrading of the 18-inch line under Hollywood to meet
the requirements of the Bureau of Engineering and Bureau of Sanitation, prior to approving
any development which would generate flows that exceed the capacity of the lines serving
the project. This plan shall be included in the Agency’s implementation plan for the
Hollywood Redevelopment Project to provide for long-term replacement or upgrading of
the 18-inch line. Alternative:
a) Reduced water consumption and recycle and reuse by the reduction in parking space from 300
to 100 – This alternative will significantly reduce the wastewater generation during the
construction phase. Also in the operational phase, assuming 2 people per car, the number of people
visiting the site will be reduced from 600 to 200. That will lead to a reduction in wastewater
generation
b) No project – This alternative yield no environmental impact

NOISE
Noise
In addition we looked at the Noise key issues to identify where future analysis must be done. For
noise and vibration, the geographic scope of potential cumulative impacts is limited to the
immediate project vicinity as well as areas adjacent to any routes designated for access and hauling.
a. Physical Setting
In the physical setting, we focus on providing noise and ground borne vibration background.
Characteristics of Sound:
Sound is technically described in terms of the loudness (amplitude) and frequency (pitch) of
the sound. The standard unit of measurement for sound is the decibel (dB). The human ear
is not equally sensitive to sound at all frequencies. The “A-weighted scale,” abbreviated
dBA, reflects the normal hearing sensitivity range of the human ear. On this scale, the range
of human hearing extends from approximately 3 to 140 dBA. There are two types of noise
sources. They are the point sources, such as stationary equipment or individual motor
vehicles; and line sources, such as a roadway with a large number of point sources (motor
vehicles).
Community Noise Equivalent Level (CNEL) and Equivalent Noise Level (Leq):
Community Noise Equivalent Level. CNEL is an average sound level during a 24-hour
period. CNEL is a noise measurement scale, which accounts for noise source, distance, single
event duration, single event occurrence, frequency, and time of day. Humans perceive sound
between 7:00 p.m. and 10:00 p.m. as if the sound were actually 5 decibels higher than if it
occurred from 7:00 a.m. to 7:00 p.m. From 10:00 p.m. to 7:00 a.m., humans perceive sound
as if it were 10 dBA higher due to the lower background level. Hence, the CNEL is obtained
by adding an additional 5 decibels to sound levels in the evening from 7:00 p.m. to 10:00
p.m. and 10 dBA to sound levels in the night before 7:00 a.m. and after 10:00 p.m.
Existing Local Noise Conditions:
The existing noise environment of this Yamashiro site is characterized a bit by vehicular traffic and
noises in the dense environment as it has a restaurant in the site. There is existing sound of people
conversing and/or cooking and kitchen domestic noises. Vehicular traffic is the primary source of
noise in the project vicinity as it is located right at the center of heart of LA, Hollywood.

Construction Impacts:
The construction impact of this site will have the resulting noise level from the activity to exceed
the existing ambient and noise level by 10 dBA. The threshold of significance for the construction
noise is 10 dBA. The redevelopment project would utilize heavy construction equipment in form of
bulldozers, cranes, loaders. These would generate noise in a short term basis.
Construction of the Project would result in temporary increases in ambient noise levels in the
Project area on an intermittent basis. The increase in noise would likely result in a temporary
annoyance to nearby residents during the construction period. Noise levels would fluctuate
depending on equipment type and duration of use, distance between the noise source and
receptor, and presence or absence of noise attenuation barriers.
Construction activities require the use of noise-generating equipment, such as jackhammers,
pneumatic impact equipment, saws, pile drivers, and tractors. Typical noise levels from various
types of equipment that may be used during construction are listed below. The table shows noise
levels at distances of 50 and 100 feet from the construction noise source.
Table 1: Noise level of typical construction equipment
The noise level shown below take into account the likelihood that more than one piece of
construction would be in operation at each phase of the construction. These noise levels are based
on the surveys conducted by US EPA during the 1970 and 1980’s. These represent the worst case
scenario and it can be clearly seen that the highest noise levels are expected to occur during the
grading/excavation and finishing phases of construction.

Table 2: Outdoor construction noise level
The Project would include excavation for the Project parking structure. The excavated area
would serve as a noise barrier to street-level sensitive receptors as the depth of excavation increases
because noise levels are directly related to the “line-of-sight” or visibility factor of the noise source.
For example, depending on the location of the sensitive receptors in relation to the excavated area,
when 15 feet of excavation has occurred, construction activities within the excavated area may not
be visible (and hence less audible) to street-level sensitive receptors. In addition, once the structural
framing and the exterior building walls have been completed, the majority of construction activity
would take place within the structure and would not substantially increase interior noise levels
at sensitive receptors.
During construction, it is assumed that 10 delivery/haul trucks and 10 construction worker vehicles
would be traveling to and from the project site daily. For an eight-hour construction workday, it
is assumed that approximately 5 to 7 delivery/haul trucks per hour would be traveling on the
surrounding streets. It is assumed that construction worker vehicles would be traveling on the
roadways during the AM and PM peak hours. The construction worker vehicles would be
distributed throughout the roadways within the vicinity of the project site. Generally, noise levels
increase by 3 dBA when the number of similar noise sources double.
Operation Impacts:
When it comes to the operational impact of this site, the roadways surrounding this segment would
experience an increase in the CNEL of about 3 dBA. As it is surrounded by the residential locality,
the resulting noise may be unacceptable. The development would include the inclusion of several
new on site equipment and facilities generating noise. New HVAC equipment can be added. As it
is a restaurant in the current site, and we assume that in future also we would have the restaurant
there, inclusion of music for the entertainment and outdoor gathering place for people could
generate some level of noise.
Mobile noise generated by the Project would not cause the ambient noise level measured at the
property line of the noise-sensitive receptor sites to increase by 3 dBA CNEL to or within the
“normally unacceptable” or “clearly unacceptable” category. Potential stationary noise sources
related to the long-term operations of the Project include mechanical equipment and parking
areas. Mechanical equipment (e.g., parking structure air vents and heating, ventilation and
air conditioning (HVAC) equipment) may generate noise levels ranging from 48 dBA to 66
Sharanya Ganesh

dBA. Therefore, stationary noise due to the re development project would result in a less-than-
significant impact.
The noise monitoring at the existing parking structure is assumed to be close to 60 dBA. Based
on an increase in parking to 300, there would be an increase in approximately 1 or 1.1 dBA over
the existing noise level. As the parking structure activity would not incrementally increase
ambient noise levels by 5 dBA or more, parking noise would result in a less-than-significant
impact. The new passage way will also be used as a loading dock and for service access operations
related to the restaurant. The project will not result in an additional noise source due to the
operation of the loading docks.
The Project would not include significant stationary sources of ground-borne vibration, such as
heavy equipment operations. Operational ground-borne vibration in the Project vicinity would be
generated by vehicular travel and delivery trucks on the local roadways. Based on field
observations, vibration levels from adjacent roadways are not perceptible at the Project Site.
Similar to existing conditions, traffic-related vibration levels would not be perceptible by
sensitive receptors. Thus, operational vibration would result in a less-than-significant impact
Mitigation Measures:
Since Project construction is expected to result in short-term temporary significant noise impacts
to sensitive receptors, the following mitigation measures are recommended to minimize the
impacts:
There should be effective noise barriers to reduce the line of site between construction
equipment and the noise sensitive barriers during the grading activities and excavation of
the mount for parking space activity, providing a sound barrier.
The noise generating equipment shall be equipped with proper noise control devices like
mufflers and enclosures. Care should be taken that no additional noise is generated due to
worn out or improper parts.
Installation of sound attenuating devices on exhaust fans, mechanical equipment. Provision
of sound absorbing might be given with the equipment if possible.
Flexible sound control curtains shall be placed around drilling apparatus and drill rigs used
within the Project Site, to the extent feasible.
The construction contractor shall establish designated haul truck routes. The haul truck
routes shall avoid noises sensitive receptors, including, but are not limited to residential
uses and schools
All residential units located within 500 feet of the construction site shall be sent a notice
regarding the construction schedule of the Project. All notices and signs shall indicate the
dates and duration of construction activities, as well as provide a telephone number where
residents can inquire about the construction process and register complaints.

There should be an acoustical analysis done. That would help in determining if the
materials to be used for the project reduce interior noise levels to or below 45 dBA or not.
If they do, then only those features shall be incorporated in the proposed project.
Major construction activity shall be limited to the hours between 7 a.m. and 9 p.m. during
the week and between 8 a.m. and 6 p.m. on Saturdays, per the City of Los Angeles
Municipal Code. Construction activities shall be prohibited on Sundays.
Alternative:
a) Reduction of parking space from 300 to 100 – This will lead to a reduction in noise level as the
number of people per car is assumed to be 2. So the number of people visiting the site is assumed
to come down from 600 to 200. This will lead to a reduction in the noise levels.
b) No Project – The No Project Alternative would not include any construction activity and, as
such, would not generate temporary noise sources that would result in increases in the ambient
noise levels. Therefore, the No Project Alternative would have no impact on the ambient noise
levels.
Conclusion:
Thus based on our analysis it is clear that alternative A, reduction of parking spaces from 300 to
100 accomplishes our project objectives and significantly mitigates the operational noise and water
impacts. Thus that is a better choice for our development site.
