Grand Avenue Widening Project Environmental Impact Report Executive Summary service F. This cannot be mitigated because there is no available right-of-way under the I-5 bridge to add an additional turn lane. Therefore, this would be an unavoidable adverse impact of the proposed project under either Alternative I or 2. Noise: As described later .in Section 3.6.4 (hnpacts Related to Noise), the construction of Alternatives 1 and 2 would result in temporary, short term significant adverse noise impacts. These potential short term noise impacts under Alternatives 1 and 2 would be substantially mitigated based on implementation of mitigation measure N-1. However, the anticipated noise levels of construction equipment and construction activities cannot be mitigated to below a level of significance, because of the proximity of the proposed widening project to adjacent noise sensitive land uses. Therefore, in the short term, the construction of the proposed Grand Avenue widening under Alternatives 1 and 2 would result in temporary significant adverse noise impacts which cannot be mitigated to below a level of significance. The long term noise impacts of the proposed Grand Avenue widening under Alternatives 1 and 2 will result in adverse noise impacts on sensitive land uses adjacent to Grand Avenue. Mitigation measure N-2, provided later in Section 3.6.5 (Mitigation Related to Noise), will substantially reduce these noise impacts, to within City standards and, therefore, to below a level of significance. Cultural Resources: As described later in Section 3.7 (Cultural Resources), the proposed Grand Avenue widening under Alternatives 1 and 2 will not result in significant adverse impacts related to archeological resources. As described later in Section 3.7.4 (Impacts Related to Cultural Resources), Alternatives 1 and 2 will result in significant adverse impacts on residences at 702 and 714 North Grand Avenue which appear to be eligible for listing on the Santa Ana Register of Historic Property. Mitigation measure CR -7 would potentially avoid or partially reduce these impacts. In the event that the City cannot avoid acquisition of these properties, the impacts of Alternatives 1 and 2 on these resources, even with implementation of mitigation measure CR -7, would be significant, adverse and unavoidable. Alternatives I and 2 could result in adverse impacts on previously unknown buried archeological resources. These impacts will be mitigated to below a level of significance based on implementation of measures CR -1 to CR -6. Growth Inducing hnnacts: As described in detail later in Section 6.1 (Growth Inducing Impacts), the proposed Grand Avenue widening would not be considered growth inducing because it will not meet any of the following criteria identified in the CEQA Guidelines: Grand Avenue is an existing arterial in a largely developed area. Public services, including streets, are already provided in this area. The existing cross section of Grand Avenue is not considered an impediment to development and the proposed widening would not provide new access to any area. The proposed widening will require the acquisition of privately owned right-of-way. Remainder parcels are anticipated to be combined and redeveloped in new uses. Those uses F.•IPROJ-ENP1Grand eirWew Text - GrandlExecutive Summary-new.doc Page ES -II
