Grand Avenue Widening Project Environmental Impact Report Section 4.0 <br />SECTION 4.0 <br />UNAVOIDABLE ADVERSE IMPACTS <br />4.1 CEQA GUIDELINES SECTION 15126(b) <br />This Section summarizes the unavoidable adverse impacts associated with Alternatives 1 and 2 <br />for the widening of the project segment of Grand Avenue. Specifically, Section 15126(b) of the <br />California Environmental Quality Act (CEQA) Guidelines requires that an Environmental <br />Impact Report (EIR): <br />"Describe any significant impacts, including those which can be mitigated, but not <br />reduced to a level of insignificance. Where there are impacts that cannot be alleviated <br />without imposing an alternative design, their implications and the reasons why the project <br />is being proposed, notwithstanding their effect, should be described." <br />Section 3.0 (Existing Conditions, Impacts and Mitigation Measures) documents the analysis of <br />the potentially significant adverse impacts associated with Alternatives 1 and 2. As discussed <br />below, these Alternatives are anticipated to result in unavoidable significant adverse impacts <br />related to land use and planning, population and housing, transportation and noise. <br />4.2 UNAVOIDABLE ADVERSE IMPACTS RELATED TO LAND USE AND <br />PLANNING <br />As described in Section 3.2 (Impacts Related to Land Use and Planning), Alternatives 1 and 2 will <br />result in adverse impacts to an established community due to the permanent changes associated <br />with the removal of existing residential uses which previously buffered interior residential <br />properties from Grand Avenue. Although the impact to the community character is not <br />quantifiable, the effect of the disruption due to the removal of existing structures is considered a <br />significant adverse impact on the existing community in proximity of the project limits along <br />Grand Avenue which cannot be mitigated to below a level of significance. <br />4.3 UNAVOIDABLE ADVERSE IMPACTS RELATED TO POPULATION AND <br />HOUSING <br />As described earlier in Section 3.3.4 (Impacts Related to Population and Housing), Alternatives 1 <br />and 2 will require the acquisition of residences and the displacement of residents. Mitigation <br />measures LP -1 and LP -4, provided earlier in Section 3.2.5 (Mitigation Related to Land Use and <br />Planning), would substantially reduce these potential impacts of the proposed widening of Grand <br />Avenue under Alternatives 1 and 2 related to population and housing. However, based on the <br />demand for affordable housing and the available housing stock, the cumulative loss of residential <br />units in the City of Santa Ana cannot be mitigated to below a level of significance, as described in <br />detail later in Section 6.2.4 (Cumulative Impacts Related to Population and Housing). Therefore, <br />Alternatives I and 2 would result in a significant adverse impact related to population and housing <br />which cannot be mitigated to below a level of significance. <br />F.IPROJ-ENMGrand eirWew Text- GrandlSection 4.0-new.doc Page 4-1 <br />
