IDENTIFIED IMPACT RELATED MITIGATION MEASURE (CONDITION OF APPROVAL) Project conditions. This modification would improve operations during the AM peak hour when compared to Cumulative (2020) Without Project conditions. During the PM peak hour, the improvement would reduce the increase in average delay to approx. 2.7 seconds between Cumulative Without Project and Cumulative With Project conditions, thus reducing the cumulative project impact at this intersection to a less - than- significant level. Alternatively, for the Blomquist Street/ Seaport Boulevard intersection to operate "acceptably' (at LOS D) during the AM and PM peak hours, implement all of the following modifications at the intersection: Restripe the northbound right turn lane to be a shared through/right -turn lane. This improvement would require the addition of a receiving lane on the north side of the intersection. Restripe the southbound approach to include a dedicated left turn lane, a shared throughAeft -turn lane, and a dedicated right turn lane. Change east/west left turns from protected to permitted phasing. With these improvements, the intersection is expected to operate at LOS D during the AM and PM peak hours under Cumulative (2020) With Project conditions. It should be noted that the addition of a second receiving lane on the north leg of the intersection would require widening of the roadway over the existing railroad tracks, requiring coordination with the railroad company and extensive re- grading of the adjacent property. Additionally, removing the east/west protected left turn phase could be Legend. Applicant = project applicant, City = City of Redwood City MONs i ORING Impl. Type of Impl Entity Action VERIFICA.
