City Place Slry Lofts Final Environmental Impact 4.2.10 TRANSPORTATION AND TRAFFIC IMPACTS RELATED TO 2030 SIGNLAIZED INTERSECTIONS 4.2.10.1 Potentially Significant Adverse Impacts Related to 2030 Signalized Intersections As discussed in Section 4.13 (Transportation and Traffic) of the EIR, in 2030, the intersections of Parker Street at La Veta Avenue and Parker Street at Town & Country Road would operate at unacceptable LOS F and LOS E, respectively, during the A.M. peak hour. Therefore, implementation of the proposed project would cause these signalized intersections to operate at an unacceptable LOS, and with an increase in the Intersection Capacity Utilization (ICLI) of greater than 0.01, representing a significant adverse impact. 4.2.10.2 Finding Related to 2030 Signalized Intersections Changes or alterations have been required in, or incorporated into, the project which avoid or substantially lessen the significant environmental effect as identified in the Final EIR. 4.2.10.3 Facts in Support ofthe Finding Related to 2030 Signalized Intersections Implementation of mitigation measures T-I and T-2, provided below, will reduce the impacts on the 2030 signalized intersections of Parker Street at La Veta Avenue and Parker Street at Town & Country Road to below a level of significance. T-1 Prior to the issuance of permits, and subject to the approval of the City of Orange, the applicant shall deposit its set fee into the Transportation System Improvement Area Joint Powers Agreement (TSIA JPA) between the cities of Orange and Santa Ana and pay its fair-share of construction costs for the following improvements at the intersection of Parker Street and La Veta Avenue: add one northbound right-turn lane; stripe the unstriped eastbound right-turn lane; convert one eastbound through lane to one shared through/right-turn lane; convert one westbound through lane to one left-turn lane; and modify traffic signal phasing to provide a protected left-turn phase for the eastbound and westbound approaches. The applicant's fair-share contribution is two percent of the construction costs.

The applicant's fair-share contribution is nine percent of the construction costs. 4.2.10.4 Level of Significance ofImpacts Related to 2030 Signalized Intersections The adverse impacts of the City Place Sky Lofts project related to the 2030 signalized intersections of Parker Street at La Veta Avenue and Parker Street at Town & Country Road will be mitigated to below a level of significance with the implementation of mitigation measures T-1 and T-2.
