ENVIRONMENTAL EFFECTS ANALYSIS

Transcription

1 Chapter 4 ENVIRONMENTAL EFFECTS ANALYSIS Introduction to the Analysis Sections 4.1 through 4.11 of Chapter 4 of this PEIR contain a discussion of the potentially significant environmental effects that may result from implementation of the proposed 2008 Master Plan, including information related to existing environmental conditions, analyses of the type and magnitude of individual and cumulative effects that implementation of the proposed 2008 Master Plan may have on such existing environmental conditions, and feasible mitigation measures that could avoid or reduce environmental impacts to a less than significant level. Scope of the EIR The environmental factors set forth below would be potentially affected by the 2008 Master Plan, involving at least one effect that is a potentially significant effect, as discussed in Sections 4.1 through Air Quality Biological Resources Cultural Resources Energy Greenhouse Gases Geology/Soils/Paleontological Resources Hydrology/Water Quality Landform Alteration/Visual Quality Land Use/Planning Noise Public Safety The 2008 Master Plan would not result in one or more potentially significant effects on the following environmental factors: Agricultural Resources, Mineral Resources, Transportation and Traffic, Population and Housing, Public Services, Recreation, and Utilities and Service Systems. The rationale for this determination is set forth in Chapter 5 of this PEIR. Format of the Environmental Effects Analysis The potentially significant environmental effects of the 2008 Master Plan are analyzed in Sections 4.1 through 4.11 by considering the conditions, principles, and standards, and by using the methodology set forth below. Page 4.0-1

2 Environmental Setting As provided in Section of the CEQA Guidelines, the analysis will include a description of the existing physical environmental conditions in the vicinity of the area affected by the proposed 2008 Master Plan, as of the date that the Notice of Preparation of this PEIR was published, namely, July 26, This description of the existing environment will establish the environmental baseline. The environmental baseline is the starting point for the analysis of the 2008 Master Plan s environmental effects; and, it enables a meaningful assessment of the significance of such effects. Regulatory Framework The analysis will also provide a summary of applicable federal, state, and local laws, regulations, plans and policies that are relevant to each environmental factor affected by the proposed 2008 Master Plan Master Plan Impacts and Mitigation The analysis will describe the potentially significant environmental impacts of the proposed project and, based upon the identified standards of significance, determine whether the environmental impacts would be considered significant and unavoidable, potentially significant but reduced to a less than significant level with mitigation, or less than significant without mitigation. Each environmental factor that is analyzed is divided into specific issues, based on potential impacts. The discussion of potential impacts is based upon the applicable threshold of significance for each issue. Where potentially significant impacts are identified, mitigation measures are included to avoid or reduce the potential impact to a level below significance. Standards of Significance As the lead agency, VWD is responsible for determining whether an adverse environmental effect identified in the PEIR is potentially significant or less than significant. Significance standards may vary depending on the nature of the area affected and, as a result, the definition of what is a significant environmental effect must be flexible. In determining standards of significance, lead agencies can obtain assistance from experts, a lead agency s policies, performance standards adopted by regulatory agencies, significance standards recommended by regulatory agencies, and the lead agency s own judgment, among other things. In addition, lead agencies may use the standards set forth in Appendix G to the CEQA Guidelines as a basis for defining significance thresholds in an EIR. The standards of significance used in this analysis are primarily based upon the recommendations provided in Appendix G of the CEQA Guidelines. The threshold of significance defines the type, amount, and/or extent of impact that would be considered a significant adverse change in the environment. The standards of significance for some environmental factors, such as air quality and noise are quantitative, while those for other topics, such as landform alteration/visual quality, are qualitative. The standards of significance are intended to assist the reader in understanding how and why an EIR determines whether an impact is potentially significant or less than significant. Impact Analysis As a Program EIR, this PEIR focuses the analysis of environmental impacts on the approval and implementation of the Master Plan and its Capital Improvement Program, recognizing that the individual CIP projects will be subject to later environmental analysis under CEQA when and if such projects are ready for approval, at which time issues unique to specific projects will be analyzed in detail in project Page 4.0-2

3 specific second tier CEQA analysis, whether in the form of an EIR, negative declaration, or addendum. As required by Section (a) of the CEQA Guidelines, direct and indirect potentially significant effects will be identified and described, while taking short-term and long-term effects into consideration. As required by CEQA Guidelines Section , this PEIR identifies and focuses on the potentially significant effects of the proposed 2008 Master Plan. In assessing the impact of the 2008 Master Plan on the environment, VWD will limit its examination to changes in the physical environment in the affected area from the environmental baseline discussed within the Environmental Setting section above. Both direct and reasonably foreseeable indirect significant effects of the proposed 2008 Master Plan on the environment will be identified and described, giving due consideration to both long term and short term effects. The PEIR provides an analysis which is sufficient to enable VWD to make an intelligent judgment concerning the potential effects of the proposed 2008 Master Plan on the environment. In drawing conclusions concerning an environmental analysis, such as whether a particular environmental effect is significant, CEQA depends upon the accumulation of substantial evidence in the record to support the conclusions, findings, and determinations made by the reviewing agency. In effect, substantial evidence is defined as enough relevant information and reasonable inferences from this information that a fair argument can be made to support a conclusion, even though another conclusion might also be reached (CEQA Guidelines Section 15384(a)). Substantial evidence includes facts and reasonable inferences from the facts and expert opinion supported by facts; it does not include argument, speculation, conjecture, or unsubstantiated opinion (California Public Resources Code Sections 21080(e) and (c)). When an EIR cannot provide meaningful information on future activities within a program, detailed environmental assessment can be deferred until such activities are ripe for approval. The individual CIP projects proposed in the 2008 Master Plan are together intended to enable VWD to reliably meet current, planned and projected land use demands in VWD s service area up to However, individually, the CIP projects would provide infrastructure addressing either localized demand or components of a larger program strategy to meet projected demand on a broad scale. As mentioned earlier, the details concerning individual CIP projects and indeed whether they would be built at all depends upon growth patterns which are actually realized in the VWD service area, water supply, conservation measures, and other factors affecting demand. Indeed, growth patterns are themselves subject to many factors, such as, changes in the area wide employment base, settlement characteristics, socio-economic trends, transportation, and environmental constraints, among others. Due to the uncertainty of future events and the ultimate character of projected growth and growth related development, project descriptions for the site-specific and individual CIP projects that would be implemented to meet resulting demand are, for the most part, similarly uncertain, particularly for the later phases of the 2008 Master Plan. The project descriptions for these site-specific individual CIP projects will be defined as the need for the CIP project ripens and the project is proposed for approval. Accordingly, as provided in CEQA Guidelines Section 15168, this PEIR addresses the environmental impacts, alternatives, and mitigation measures that can be meaningfully assessed at the program level (i.e., at the level of the 2008 Master Plan). The analysis of issues unique to the site-specific individual CIP projects would, as appropriate, be conducted at a later time in accordance with CEQA prior to the approval of such projects, which analysis would be focused by tiering from the environmental analysis conducted in this PEIR. The individual CIP projects would be examined by VWD in the light of the PEIR to determine whether an additional environmental document must be prepared. For CIP projects that would have effects that Page 4.0-3

4 were not examined in the PEIR, VWD would prepare a new initial study leading to either an EIR or a negative declaration. If VWD finds, pursuant to CEQA Guidelines Section 15162, no new effects could occur or no new mitigation measures would be required for a CIP project, VWD can approve the CIP project as being covered by the PEIR, and no new environmental document would be required. VWD would incorporate all applicable feasible mitigation measures and alternatives developed in the PEIR into subsequent CIP projects together with any new mitigation measures or alternatives adopted as a part of the second tier CEQA project specific analysis. This PEIR utilizes the following terms to describe the level of significance of impacts identified during the course of the environmental analysis: Less than Significant This term is used when an environmental effect would not exceed the defined standards of significance, namely, 1) when the effect is not a substantial or potentially substantial adverse change to the environment, and 2) when potentially significant impacts are reduced to a level which is less than significant after implementation of mitigation measures. Potentially Significant This term is used to refer to impacts on the environment resulting from implementation of the proposed 2008 Master Plan that exceed the defined standards of significance before identification of mitigation measures. A significant effect is defined by Section of the CEQA Guidelines as a substantial, or potentially substantial, adverse change in any of the physical conditions within the area affected by the project including land, air, water, minerals, flora, fauna, ambient noise, and objects of historic or aesthetic significance. An economic or social change by itself shall not be considered a significant effect on the environment *but+ may be considered in determining whether the physical change is significant. For impacts that exceed a threshold of significance, feasible mitigation measures that avoid or reduce the potential impact are identified. Significant and Unavoidable This term is used to refer to significant impacts resulting from implementation of the proposed 2008 Master Plan that cannot be eliminated or reduced to below standards of significance through implementation of feasible mitigation measures. Mitigation Measures Section of the CEQA Guidelines requires an EIR to describe feasible measures which could minimize significant adverse impacts. The CEQA Guidelines define feasible as a quality attributable to an action capable of being accomplished in a successful manner within a reasonable period of time taking into account economic, legal, social, technological, or other considerations. The PEIR will identify and describe mitigation measures that could reduce the severity of potentially significant impacts identified as part of the Impact Analysis. Cumulative Impacts and Mitigation Cumulative impacts are defined in the CEQA Guidelines as two or more individual effects which, when considered together, are considerable or which compound or increase other environmental impacts. So, a cumulative impact is a change in the physical environment that results from the incremental effect Page 4.0-4

5 of the project when added to other past, present, and reasonably foreseeable future projects. In determining whether a project s cumulative effects are significant, two determinations are required: 1. Is the combined impact of the project and other projects significant? 2. Cumulative impacts can result from individually minor but collectively significant projects taking place over a period of time. Is the project s incremental effect cumulatively considerable? The CEQA guidelines allow for a project's contribution to be rendered less than cumulatively considerable with implementation of mitigation measure(s) designed to alleviate the cumulative impacts. An EIR s discussion of cumulative impacts must reflect the severity of the impacts and the likelihood of their occurrence. However, the discussion need not be as detailed as the discussion of environmental impacts attributable to the project alone and should be guided by the standards of practicality and reasonableness. The geographic scope of the cumulative impact analysis varies depending upon the specific environmental topic being analyzed. In accordance with CEQA Guidelines Section 15130(b)(3), Table summarizes the geographic area within which past, present, and reasonably foreseeable future projects may contribute to a specific cumulative impact, when considered in conjunction with the impacts associated with implementation of the proposed 2008 Master Plan. CEQA Guidelines Section 15130(b) indicates the following approaches for identifying cumulative projects: A list of past, present, and probable future projects producing related or cumulative impacts, including, if necessary, those projects outside the control of the agency; or A summary of projections contained in an adopted general plan or related planning document, or in a prior environmental document which has been adopted or certified, which described or evaluated regional or area-wide conditions contributing to the cumulative impact. The cumulative analysis for this PEIR uses a combination of the two approaches listed above. For each environmental topic addressed in Chapter 4 of this PEIR, the regional or area-wide conditions and cumulative projects contributing to a particular cumulative impact (as identified and projected in the relevant general plans of jurisdictions located within and adjacent to the VWD planning area) is considered as part of the baseline when evaluating the proposed 2008 Master Plan s contribution to that cumulative impact. In accordance with CEQA Guidelines Section 15130(b)(5), a determination is made regarding the significance of the baseline cumulative impact (prior to considering the cumulative contribution of the 2008 Master Plan) resulting from the full range of regional or area-wide conditions and cumulative projects that occur within the specific geographic areas described in Table A Summary Box will provide the reader a convenient capsule of the issue statement, a description of the cumulative impact, the significance of the baseline cumulative impact, and whether or not the proposed 2008 Master Plan s contribution to this impact is cumulatively considerable (before and after implementation of mitigation measures).

6 Table Geographic Scope of Cumulative Impact Analyses Environmental Topic Air Quality Biological Resources Geographic Scope of Cumulative Impact Analyses The geographic scope of cumulative impact analysis for criteria air pollutants is the San Diego Air Basin. The entire VWD service areas, and all proposed CIP projects would be located within the San Diego Air Basin. The geographic scope of cumulative impact analysis for biological resources includes the VWD service area, which encompasses a large region of Northern San Diego County and represents a wide variety of habitat types and sensitive biological resources, including a comprehensive list of species of regional concern. For federally listed species whose critical habitat occurs within the VWD service area (e.g., coastal California gnatcatcher), the geographic scope for the cumulative impact analysis encompasses all contiguous critical habitat units that extend beyond the boundaries of the VWD service area. Cultural Resources The geographic scope of cumulative impact analysis is the VWD service area, which includes 45-square miles of land with a similar archaeological, ethnohistoric, and historic setting as the individual CIP project sites. Energy Global Climate Change Geology/Soils/ Paleontological Resources Hydrology/ Water Quality Landform Alteration/ Visual Quality Land Use/ Planning Noise Public Safety The VWD service area is the geographic scope of cumulative for energy. This area was chosen as the geographic scope of analysis because it encompasses a 45-square mile area with a population of approximately 86,000 people. Due to the nature of assessment of greenhouse gas emissions and the effects of climate change, impacts can currently only be analyzed from a cumulative context. Therefore, the geographic scope for the cumulative analysis of global climate change is the global atmosphere for greenhouse gas emissions. For seismic hazards and other geologic/soils conditions (fault rupture, groundshaking, ground failure, liquefaction/collapse, landslides, lateral spreading, subsidence, expansive soils), no cumulative study area exists because impacts would be specific to proposed CIP project sites. For soil erosion, the geographic scope of cumulative analysis includes the Carlsbad and San Luis Rey watersheds, which are located directly downstream from proposed CIP construction sites. For paleontological resources, the cumulative impact area includes the paleontological sensitive geologic formations within the VWD service area, a 45-square mile area. For surface water quality, the cumulative impact study area includes the Carlsbad and San Luis Rey watersheds. This geographic scope of analysis was chosen to include watershed areas relevant to the VWD service area boundary. Visual impacts tend to occur on a localized level. Therefore, the geographic scope for the cumulative analysis of landform alteration and visual quality include public viewsheds from which above-ground CIP projects would be visible. Incompatibilities with adjacent land uses are generally site specific. Therefore, the geographic context for the analysis of cumulative impacts relative to adjacent land use incompatibilities includes development characteristics surrounding proposed 2008 Master Plan CIP facilities and zoning regulations in the vicinity of wastewater projects. For conflicts with habitat conservation plans and natural communities conservation plans, the cumulative impact study area includes all of the open space reserves within and adjacent to the VWD service area, as identified by MSCP s and MHCP s of local agencies. Impacts related to noise are generally site specific; therefore, the geographic scope for the cumulative analysis of noise includes residential projects and other sensitive noise receptors directly adjacent to proposed CIP project construction sites, and projects adjacent to roadways and freeways used by construction-related traffic along which the projected increase in construction traffic could exceed noise standards. Impacts relative to hazardous materials are generally specific to the site involving the hazardous material use. Therefore, the geographic scope of cumulative analysis for public safety includes the roadways, freeways and local access areas used by vehicles transporting hazardous materials to and from proposed CIP construction sites, and the CIP project sites that involve the use of hazardous materials and/or could result in the accidental release of a hazardous material.

7 The following sources were included in the consideration of cumulative projects for the 2008 Master Plan: 1) Projections based on adopted general or regional plans; and 2) Present, past and probable future cumulative projects within or near the VWD service area. All cities and counties in California are required by state law to create and adopt a general plan that covers each jurisdiction s entire planning area. This plan must address a broad range of issues associated with development, including the identification of growth projections for future population and employment within the county or city. In San Diego County, SANDAG maintains the most current economic, demographic, land use, and transportation data projections for the county and incorporated cities. The adopted general plans of the unincorporated county of San Diego and incorporated cities are consistent with SANDAG projections. With regard to present and probable future projects, the following planning documents were included in the consideration of cumulative impacts: 1) County of San Diego General Plan, 2) Vista General Plan, 3) San Marcos General Plan, 4) Escondido General Plan, and 5) Carlsbad General Plan. The County of San Diego General Plan is available for review on the County of San Diego s website: The Vista General Plan is available for review at The San Marcos General Plan is available for review at San Marcos City Hall, 1 Civic Center Drive, San Marcos, CA The Carlsbad General Plan is available for review on the City of Carlsbad s website: The Escondido General Plan is available for review at Tables through provide a summary of the growth, employment and housing projections for the General Plans adopted in these jurisdictions. In addition to projections included in such General Plans, the cumulative impacts analysis of this PEIR also considers the cumulative impacts arising from the proposed 2008 Master Plan and present, past and probable future projects located within the above mentioned jurisdictions. These other projects are listed in Table In addition, the cumulative impacts analysis for the 2008 Master Plan includes projects listed in SANDAG s 2030 Regional Transportation Plan (RTP). Approved in 2007, the RTP was developed to meet San Diego s long-term mobility needs, better connect transportation and land use policy decisions, and create a transportation network that will serve the San Diego region until The 2030 San Diego RTP proposes approximately 85 new or improved transit projects, high occupancy vehicle connector routes, highway system completion routes, freeway connectors, transit facilities, arterial transit improvements, and international transportation projects. Table lists the RTP projects proposed within or near the VWD planning area that have been included in the cumulative analysis. The 2030 San Diego RTP is available at Page 4.0-7
