4.0 Cumulative Analysis air quality impacts are analyzed based on regional‐scale growth; thus, a regional perspective must be used to assess cumulative air quality impacts. Aesthetic impacts, given the localized impact area of concern, require consideration of both a smaller, more localized area that surrounds the immediate project area and a community scale that encompasses the larger community within which the SVRA is located. Table 4‐1 presents the geographic scales associated with the different resources addressed in this DEIR analysis. TABLE 41. GEOGRAPHIC SCOPE OF CUMULATIVE IMPACTS Resource Issue Geographic Scope of Impacts Air Quality Local (carbon monoxide, particulate matter, air toxics) and air basin/regional (ozone and particulate matter) Biological Resources Local Cultural Resources Archaeological survey area (local) Sacramento Valley (regional) Geology and Soils Local Hazards and Hazardous Materials Local and community Hydrology and Water Quality Local and regional areas within the same watershed and aquifer Noise Local Transportation and Traffic Regional and local Public Services and Utilities Regional and community Visual Resources Local and community Climate Change Global (GHGs) Source: Data compiled by AECOM in 2011 4.3 Cumulative Forecasting Methodology The State CEQA Guidelines allow for use of either the list method or the regional growth projections method to determine the scope of related projects for the cumulative impacts analysis (State CEQA Guidelines Section 15130). The list method involves preparing a list of past, present, and reasonably anticipated future projects that produce or would produce related or cumulative impacts, including those projects outside the control of the agency. The regional growth projections method involves preparing a summary of projections contained in an adopted general plan or a related planning document that is designed to evaluate regional or areawide conditions. Both approaches were used in this DEIR because although the Clay Pit SVRA General Plan identifies specific land uses for a specific locality, it would be implemented in an area that has experienced and will continue to experience regional growth. This method allows for a thorough, project‐based cumulative analysis within the defined plan area. However, certain issues that Clay Pit State Vehicular Recreation Area February 2012 4-2 Draft EIR
4.0 Cumulative Analysis extend far beyond the project vicinity (e.g., air quality, global climate change) also rely on projections. 4.3.1 Regional Growth Projections Clay Pit SVRA is located within unincorporated Butte County. As determined through visitor surveys, visitors to the SVRA are primarily from the local area (less than 50 miles). Implementing the General Plan, including constructing and operating the headquarters facilities, would enhance recreational opportunities for the surrounding community. Butte County is expected to experience population growth as shown in Table 4‐2. TABLE 42. REGIONAL GROWTH PROJECTIONS Jurisdiction Year Total Increase 2006 2010 2020 2030 2006–2030 Percent Change 20062030 Butte County 217,209 232,075 276,277 321,315 104,106 +48 Source: BCAG 2010 This type of regional and local growth has the potential to result in numerous environmental issues such as traffic congestion, air quality degradation, biological habitat loss, water quality degradation, and other environmental changes. This cumulative analysis considers the regional growth trends and the specific projects discussed below. 4.3.2 List of Cumulative Projects in the Vicinity Information on past, present, and reasonably foreseeable future projects and on identified project impacts were gathered from Butte County, the City of Oroville, and the California Department of Transportation through review of available environmental documentation and consultation with planning staff (conducted January 2011). Table 4‐3 shows a summary of project information and identified project impacts for these projects. Figure 4‐1 shows the locations of the cumulative projects. 4.4 Cumulative Impact Analysis As described in Section 4.2 and Table 4‐1, the cumulative scenario under each environmental discipline differs depending on the potential area of effect. For example, the cumulative analysis for regional air quality considers impacts within the entire air basin because air quality impacts occur on a regional or basin‐level scale, while the cumulative analysis for archaeology is limited to a local scale because the ground‐disturbing activities would be local. The cumulative setting, limitations, and analysis for each discipline are discussed as appropriate below. Clay Pit State Vehicular Recreation Area Draft EIR 4-3 February 2012
