NOTICE OF PREPARATION OF A PROGRAM ENVIRONMENTAL IMPACT REPORT
SANTA CLARA COUNTY GENERAL PLAN
CIRCULATION AND MOBILITY ELEMENT UPDATE
County of Santa Clara, California May 27, 2014
1. Introduction The purpose of an Environmental Impact Report (EIR) is to inform decision makers and the general public of the environmental effects of a proposed project. The EIR process is intended to provide public agencies with the environmental information required to evaluate a proposed project, establish methods for reducing adverse environmental impacts, and consider alternatives to a project, prior to the approval of the project. The Program EIR for the proposed Circulation and Mobility Element Update will be prepared and processed in accordance with the California Environmental Quality Act (CEQA) of 1970, as amended. Per Section 15168 of the CEQA Guidelines, a Program EIR will be prepared, which is appropriate for projects, such as a general plan element, that include a series of related actions that can be characterized as one project and in connection with the issuance of rules, regulations, plans and other policies that govern a continuing program. A Program EIR allows a lead agency to consider broad policy alternatives and program-wide “first tier” mitigation strategies that help guide the analysis of subsequent individual projects. In accordance with the requirements of CEQA, the EIR will include: • A project summary. • A project description. • A description of the existing environmental setting. • The significant environmental effects of the proposed project. • The significant environmental effects that cannot be avoided if the proposed project is
implemented. • The significant irreversible environmental changes caused by the proposed project. • The growth-inducing impact of the proposed project. • The mitigation measures proposed to minimize the significant effects. • The alternatives to the proposed project. 2. Project Location The Santa Clara County General Plan Circulation and Mobility Element Update will identify objectives, policies, and strategies for multimodal transportation networks, airports, and utilities within the County of Santa Clara, California. The County, which encompasses approximately 1,300
2
square miles, is located at the southern end of the San Francisco Bay Area and includes 15 incorporated cities and towns (San Jose, Campbell, Cupertino, Gilroy, Los Altos, Los Altos Hills, Los Gatos, Milpitas, Monte Sereno, Morgan Hill, Mountain View, Palo Alto, Santa Clara, Saratoga, and Sunnyvale) (refer to Figure 1). 3. Description of the Project The proposed project is an update to the County of Santa Clara’s Circulation and Mobility Element, one of the State-mandated elements of the General Plan. The draft update is designed to be consistent with the requirements of the California Complete Streets Act and the Governor’s Office of Planning and Research Update to the General Plan Guidelines: Complete Streets and the Circulation Element. Circulation includes all systems that move people, goods, energy, water, sewage, storm drainage, and communications. Issues addressed in the Circulation and Mobility Element include Countywide Issues and Policies, the County Roads System, Private Roads in Unincorporated Areas, Airports, and Utilities. The Circulation and Mobility Element identifies the transportation network under the County’s jurisdiction to support existing and future land use patterns in the County in 2025 and through 2040, based on projected growth in adopted General Plans of the incorporated cities and towns within the County. It also contains policies to support and implement improvements to the transportation network, including bicycle, pedestrian and transit systems. The 1995 Countywide Trails Master Plan and multimodal policies are addressed in the Countywide Transportation Issues and Policies section. Bicycle routes and trails are also considered in the County Roads System section where bicycle routes/trails occur within County roads rights-of-way. The County of Santa Clara is unique in that it is the only county in the State of California that maintains and operates a regional expressway system within incorporated areas, in addition to roads in unincorporated areas. The Circulation and Mobility Element Update will identify possible future modifications to the County roads and expressway systems, based upon transportation modeling and a consideration of complete streets in conformance with State law. The list of improvements for County expressways is derived from input from local cities, the existing County Expressway Plan and the draft Expressway Plan 2040, which is currently being prepared by the County. A summary of possible transportation improvements that may be included in the future transportation network are provided in Table 1 (County Roads) and Table 2 (County Expressways). Most of the roadways identified on the Tables 1 and 2 are currently identified for future improvements in existing plans (e.g., County Expressway Plan, Countywide Trails Master Plan, and Santa Clara County General Plan). The Update proposes to modify some of the planned roadway improvements in existing plans, based upon updated transportation modeling and new standards for multimodal design of bike lanes, pedestrian paths, and vehicular turning pockets on two-lane arterial roadways. The location of the County roads and expressway improvements are shown in Figure 2 and 3, respectively.

Notes: SB = Southbound, NB = Northbound, WB = Westbound, EB = Eastbound: HOV = High Occupancy Vehicle “Intersection improvements” include addition and/or extension of turning lanes, signalization changes, and/or intersection reconfigurations to improve level of service or operations/safety. Possible projects listed include larger-scale improvements that could result in substantial physical disturbance and/or otherwise change the capacity of an expressway. Modifications or changes to expressways (major and minor) identified at a program-level in the Circulation and Mobility Element would require project-level environmental review prior to construction.
13
The strategies and policies in the Circulation and Mobility Element Update will address right-of-way dedication and street improvements as part of new development, funding, timing, and private roads. The Santa Clara County Complete Streets Policy (November 2012) will be integrated into the Circulation and Mobility Element Update. Utilities policies and information in the Circulation and Mobility Element Update will consider the location and extent of sewer, water and drainage line and facilities, fuel and natural gas pipelines, power plants, transmission lines and corridors, telecommunication cables and corridors, proposed or state identified transmission line corridors, renewable and non-renewable energy and energy storage. Development, improvement, and current and future locations of these facilities and any conflicts will be addressed. Policies for airports under Santa Clara County’s jurisdiction (Reid-Hillview, Palo Alto, and South County Airports) will be included in the Circulation and Mobility Element Update. The focus of these policies will be development and improvement of aviation facilities as considered in each airport’s Master Plan, and consistency with the provisions of each airport’s Comprehensive Land Use Plan (addressing compatibility of land uses around each airport), and access to and from aviation facilities. Consistency with plans for other airports within the County (e.g., Norman Y. Mineta San José International Airport and Moffett Federal Airfield) will also be addressed. 4. Potential Environmental Impacts of the Project The potential physical environmental impacts of implementing the Circulation and Mobility Element Update will fall into two main categories: 1) the impacts associated with future construction of new or expanded roadway or circulation facilities; and 2) the anticipated impacts associated with implementation of circulation and mobility policies. As a program-level planning document, the Circulation and Mobility Element provides generalized locations for new transportation or utility facility modifications. The level of analysis in the Program EIR will be commensurate with the level of detail available. Project-level environmental review would be required prior to construction of the planned roadway modifications identified in the Circulation and Mobility Element. Implementation of the Circulation and Mobility Element Update and associated individual projects over time may result in the following impacts: Aesthetics, including the visual change resulting from new facilities in the context of existing rural landscapes, visually sensitive locations, and existing scenic resources. Agricultural and Forestry Resources, including the potential for planned facilities to develop or otherwise adversely affect farmland or forestry resources. Air Quality, including project consistency with the Clean Air Plan, the potential for increased vehicle miles traveled (VMT) and associated criteria air pollutant emissions, and temporary air quality impacts during construction.
14
Biological Resources, including the potential for planned facilities to affect protected plants, animals, and habitats, and project consistency with the Santa Clara Valley Habitat Plan (VHP). Cultural Resources, including the potential for the construction of planned facilities to disturb archaeological, paleontological, and/or historic resources. Energy, including the potential for increased VMT and associated increase in energy use and energy use during the construction and maintenance of planned roadway facilities. Geology and Soils, including the potential for planned facilities to be affected by seismic, soil, or geology constraints. Greenhouse Gas Emissions, including project consistency with the County of Santa Clara Climate Action Plan and State and regional plans, the potential for increased VMT and associated greenhouse gas emissions, and the vulnerabilities of existing and planned infrastructure to the effects of climate change (e.g., rising sea levels). Hazards and Hazardous Materials, including the transport of hazardous materials on the existing and planned roadway network, consistency with adopted airport land use plans related to safety, the ability of the existing and planned roadway network to support emergency response, and the potential for hazardous materials to be encountered during construction of planned facilities. Hydrology and Water Quality, including the potential for planned facilities to increase runoff or adversely affect water quality, groundwater, drainage patterns, or be affected by flooding. Land Use, including the potential for planned facilities or facility modifications to disrupt or divide communities, conflict with adopted plans or policies, or adversely affect adjacent land uses. Noise, including noise increases from new or expanded facilities and construction noise. Population and Housing, including the potential for inducing population growth in an area through the expansion or extension of roadway facilities and/or utility infrastructure. Public Services and Recreation, including the potential for new or expanded facilities to result in significant environmental effects on public services or recreational facilities. Transportation, including the effects of the Circulation and Mobility Element Update on vehicular, bicycle, and pedestrian circulation and safety based on forecasted changes to County-wide circulation patterns, and project consistency with applicable adopted transportation plans, policies, and programs taking into account all modes of transportation. Utilities and Service Systems, including construction of new or expanded facilities that could result in significant environmental effects.
15
Alternatives to the Project The EIR will evaluate possible alternatives to the proposed project, based on the results of the environmental analysis. The alternative discussion will focus on those alternatives that could feasibly accomplish most of the basic purposes of the project and could avoid or substantially lessen one or more of the significant environmental impacts of the project (CEQA Guidelines Section 15126.6). Alternatives to the project as proposed, including “No Project” will be discussed. Other alternatives to be evaluated may include Modified Project Components Alternatives (e.g., modified Circulation and Mobility Element policies) or Location Alternatives of planned improvements that result in significant impacts. Cumulative Impacts The EIR will include a Cumulative Impacts section which will address the significant cumulative impacts of the Circulation and Mobility Element Update when considered with other past, present and reasonably foreseeable future general plan amendments in the area.
Growth Inducing Impacts The EIR will discuss the ways in which the project could foster economic or population growth, or the construction of additional housing, either directly or indirectly, in the surrounding area. Other CEQA Sections The EIR will include other sections required by CEQA, including Significant Unavoidable Impacts, Significant Irreversible Environmental Changes, Lead Agency and Consultants, and References. Relevant technical reports (e.g., traffic, air quality, and noise analyses) will be attached as appendices to the EIR.
