i~ <br />i~ <br />L <br />r <br />i~ <br />i~ <br />i~ <br />i~ <br /> <br />Environmental Checklist <br />For CEQA Compliance <br />quality thresholds account for other activity occurring within the region, and the regional <br />thresholds are used to determine whether individual projects would result in significant <br />impacts when combined with other activities assumed to occur within the region. Thus, <br />when individual project impacts fall below regional air quality thresholds, they are <br />assumed to also be less than cumulatively considerable. <br />Implementation of the proposed project has the potential to result in the disturbance of <br />undiscovered cultural resources. In conjunction with the projects listed above, the <br />proposed project would have the potential to contribute to a cumulative impact to cultural <br />resources. The mitigation measures identified in Section V-B, and V-D would reduce the <br />significance of impacts to cultural resources associated with disturbance of an <br />undiscovered cultural resource. Other projects in the vicinity of the proposed project <br />would be required to implement similar measures. As such, cumulative impacts <br />associated with the proposed project would not be cumulatively considerable. <br />Implementation of the proposed project may result in the disposal of asbestos-containing <br />building materials, lead based paint, and PCB-containing lighting ballasts. In conjunction <br />with the projects listed above, the proposed project would have the potential to contribute <br />to a cumulative impact to hazards and hazardous materials. The mitigation measure <br />identified in Section VII-A would reduce the significance of impacts associated with <br />disposal of hazardous materials to aless-than-significant level. Hazardous waste that <br />may be found at other project sites would be disposed of according to local, state, and <br />federal requirements. Implementation of the mitigation measure provided as part of the <br />proposed project and implementation of other safety measures in the cumulative <br />scenario would reduce cumulative impacts associated with the proposed project to less <br />than cumulatively considerable levels. <br />Implementation of the proposed project has the potential to generate stormwater runoff. <br />In conjunction with the projects listed above, the proposed project has the potential to <br />contribute to a cumulative impact to hydrology and water quality. The mitigation measure <br />identified in Section VIII-A would reduce the significance of impacts to hydrology and <br />water quality to a less than significant level. Other projects in the vicinity of the proposed <br />project would be required to institute WQMPs and implement BMPs. Implementation of <br />WQMPs and BMPs in a cumulative scenario would reduce cumulative impacts <br />associated with the proposed project to less than cumulatively considerable levels. <br />• Implementation of the proposed project has the potential to expose people to excessive <br />noise. Implementation of mitigation measures identified in Section XI-A and XI-B would <br />reduce impacts from noise exposure to aless-than-significant level. Projects in the <br />vicinity of the proposed project would be required to institute similar measures if they <br />were found to expose people to excessive noise. Implementation of mitigation measures <br />' would reduce cumulative impacts associated with the proposed project to a less than <br />cumulatively considerable levels. <br />Although the proposed project would result in less-than-significant environmental impacts, <br />the impacts from the cumulative developments would not be significant when combined with <br />other cumulative projects. Thus, because there are no significant cumulative impacts, <br />impacts associated with the proposed project would not be cumulatively considerable. <br />Alton Court <br />Initial StudylMitigated Negative Declaration <br />3-43 <br />August 2007 <br />J8S 00635.07 <br />75A-109 <br />
