12/17/2007 project impact at the Blomquist Street/Maple Street intersection (see Secondary Impact 7-10A which follows). Findings: The extension of Blomquist Street over Redwood Creek to the East Bayshore/Bair Island Road intersection would reduce the impact described above to a less- than-significant level. E. Proiect-Related Secondary Impact of the Blomquist Extension on the Blomquist Street/Maple Street Intersection. Secondary Impact 7-10A: With completion of the Blomquist Street Extension, the Blomquist Street/Maple Street intersection would be expected to operate at LOS C (acceptable) conditions during the AM peak hour and LOS F (unacceptable) conditions during the PM peak hour under Background Conditions. With the addition of the project traffic, operations at the intersection would be expected to degrade to LOS D (acceptable) conditions during the AM peak hour and worse LOS F (unacceptable) conditions during the PM peak hour. The change in the PM average delay at the intersection due to the project is expected to be more than 5.0 seconds. The intersection is also expected to satisfy the Caltrans Peak-Hour Volume Warrant for traffic signal installation during the PM peak hour under Project Conditions. These secondary effects of Mitigation 7-10, the Blomquist Street Extension, would represent a significant secondary impact. Secondary Mitigation 7-10A. To mitigate project-related secondary traffic impacts at the Blomquist Street/Maple Street intersection: (a) the intersection shall be four-way stop-controlled; and (b) the northbound approach shall be widened to include a dedicated left turn lane and a shared through/right-turn lane. With these improvements, the intersection is expected to operate at LOS C during the AM and PM peak hours under Project Conditions. Alternatively, install a traffic signal at the intersection. With signalization, the intersection is expected to operate at LOS B during the AM and PM peak hours under Project Conditions. Or, as a third alternative, install a roundabout at the intersection. With the roundabout, the intersection would operate at LOS A during the AM and PM peak hours under Project Conditions. Implementation of one of these secondary mitigation alternatives to City satisfaction would be a Project responsibility. Findings: Implementation of anyone of these three mitigation alternatives would reduce the project's secondary impact at the Blomquist Street/Maple Street intersection to a less-than-significant level. F. Proiect Impacts on C/CAG's Congestion Management Plan (CMP) Roadwav Network--AM and PM Peak Hours. Potential Impact 7-11: The proposed project is expected to generate 320 net new peak-hour trips during the AM peak hour and 342 net new peak-hour trips during the PM peak hour. Because the project trip generation rate is more than 100 net new peak-hour trips and the project is subject to CEQA review, the proposed project must meet the requirements presented in the C/CAG Guidelines for the Implementation of the Land Use Component of the Atty/Reso/Reso.1772 121707 12 14829 Muff# 613
