Grand Avenue Widening Project Environmental Impact Report Section 3.0 At Seventeenth Street, an exclusive right turn lane would be required on the westbound approach to achieve LOS D. This improvement would require additional widening on the north side of Seventeenth Street east of Grand Avenue. This improvement has been included in the proposed project. The additional properties for the right-of-way have been accounted for in the total parcels affected by the proposed project. Alternatives 1 and 2 will not result in adverse impacts related to on street parking and SCAG transportation policies. No mitigation is required. 3.5.7 MITIGATION RELATED TO ACCESS The following mitigation measures address the significant temporary adverse access impacts for Alternatives 1 and 2 as discussed in Section 3.5.5 (Impacts Related To Access During Construction). T-1 Prior to initiating construction on the selected widening alternative for each construction phase and segment of Grand Avenue, the City of Santa Ana will ensure that the project contractor prepares traffic detour plans and construction truck access routes for that phase of project construction. The plans will provide details to ensure access to existing developments along the project roadway segments and provide traffic control in the project area(s) during construction activities for each construction phase. The City of Santa Ana will work with local businesses affected by the road widening project to ensure that the businesses will be able to operate while road widening construction activities are underway. The City of Santa Ana will review and approve the contractor's detour plans and truck access routes. T-2 Prior to commencing construction for individual segments of Grand Avenue, The City of Santa Ana Public Works Agency and the project contractor will meet with representatives from businesses on each project segment to identify individual business access needs during construction. The defined access routes and entries to individual sites will be clearly shown on all construction plans. T-3 The City of Santa Ana will provide signs that indicate the project construction limits, access routes, alternative routes, detour routes and entries to individual business sites for each project segment and phase. 3.5.8 LEVEL OF SIGNIFICANCE AFTER MITIGATION RELATED TO TRANSPORTATION AND ACCESS The proposed widening of Grand Avenue under Alternatives 1 and 2 will largely result in beneficial effects on traffic operations on the project segment of Grand Avenue. However, implementation of either alternative will result in a significant avoidable adverse impact at the intersection of Grand Avenue and Santa Ana Boulevard at the southbound right turn lane in the PM peak hour in 2020. Alternatives 1 and 2 will not result in adverse impacts related to on street parking and SCAG transportation policies. F: TROJ-ENVAGrand eirWew Text - GrandlSection 3 Split&ction 3.5.doc Page 3.5-23
