IDENTIFIED IMPACT frontage. Construction of the proposed project could result in insufficient right -of -way width along Bair Island Road to accommodate such facilities. This effect would represent a significant impact. Impact 7 -10: Project Condition Emergency Access Impact. During an emergency evacuation of the Bair Island Road area with the proposed project at full occupancy, volumes on Bair Island Road, East Bayshore Road, and Whipple Avenue (near the project site) could be expected to exceed roadway capacities, resulting in LOS F operations. This effect would represent a significant impact. A sensitivity analysis has been conducted to determine how many new project residential units could be developed in the Bair Island Road area before the Blomquist Street Extension would be needed to maintain adequate emergency access. The results of the analysis (available for review at the City of Redwood City Community Development Services Department, City Hall, 1017 Middlefield Road) indicate that the existing roadway has the capacity to accommodate 750 new dwelling units before a secondary access would be needed to accommodate the assumed emergency scenario. Secondary Impact 7 -10A: Project - Related Secondary Impact of the Blomquist Extension (Mitigation 7 -10) on the Blomquist Street/Maple Street Intersection. With completion of the Blomquist Street Extension, the Blomquist Street/Maple Street intersection would be expected to operate at LOS D during the AM peak hour and LOS F 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 F during both the RELATED MITIGATION MEASURE (CONDITION OF APPROVAL) preclude future construction of adequate bicycle facilities in the area and this impact would be reduced to a less -than- significant level. Mitigation 7 -10. The extension of Blomquist Street over Redwood Creek to the East Bayshore Road/Bair Island Road intersection is currently planned by the City and partially funded. The Blomquist Street Extension over Redwood Creek would reduce this potential emergency access impact to a less - than- significant level- -i.e., would provide sufficient emergency access to the Bair Island Road area with full buildout of the proposed project. This additional access is also expected to change local vehicular travel patterns and the assignment of project- generated traffic, resulting in a potentially significant secondary project Impact at the Blomquist Street/Maple Street intersection (see Secondary Impact 7 -10A which follows). 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. Legend.
