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.

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.
