Chapter 4 Environmental Setting, Impacts, and Mitigation Measures O. Transportation and Traffic At the two remaining intersections identified under Impact 01 a, mitigation measures avail- able would not be adequate to meet standards: . Bernal @ Valley: Restripe westbound right turn lane as through-right turn lane (no widening required). Post-mitigation LOS D (47.1 )/E (75.9) for the AM and PM peak hour. Opening the striped out third eastbound through lane would improve the PM LOS to D (LS); however, this lane is currently striped out to constrain capacity at this gateway. . Valley @ Blackbird: Installing a new traffic signal would result in LOS D or better. However, the LOS is E (38.8) during the PM peak hour if only stop controls are provided. City staff recommends a signal under the cumulative condition and the cumulative analysis (see 01 b) assumes signalization. Significance Post-mitigation: significant and unavoidable. Impact OJ b. The project would contribute to unsatisfactory levels of service at 24 intersections under the cumulative + project scenario. Measure 01 b. The following intersection improvements are required to maintain LOS D or better conditions under the cumulative + project scenario. Intersection Bernal @ 1-680 SB Bernal @ Kottinger Bernal @ Main First @ Kottinger/Spring First @ Ray / Vineyard Foothill @ Canyon Way Foothill @ Castlewood Hacienda @ Owens Improvement See discussion below. Install new traffic signal. The 1996 General Plan recommends a traffic signal at this intersection. Install new traffic signal. The General Plan exempts this intersection from the LOS D standard. Making Spring Street one- way westbound would significantly reduce delay at this intersection. The General Plan exempts this intersection from the LOS D standard. Providing permissive phas- ing on the east and westbound approaches and adding a second eastbound left turn would sig- nificantly reduce delay at this intersection. Remove westbound right turn island and permit westbound through-right turn lane. Widen Foot- hill to provide 4th northbound through lane. Install traffic signal. Provide SB/EB triple left turn lanes. Post-mitigation Condition su LOS A (5.6)/LOS A (6.7) for the AM and PM peak hour. LS LOS A (9.7)/B (10.3) forthe AM and PM peak hour. LS LS LS LOS C (33.8)/D (47.2) for the AM and PM peak hour. LS LOS D or better. LS LOS D or better (53.2 second delay in PM peak hour). LS 147
