intersection in one of the two alternative ways listed below. The Project sponsor would pay its fair share of the cost of this measure. . Add a second southbound through \ane on Veterans Bou\evard (and add emergency vehicle signal pre-emption to the traffic signal control), or . Add a second westbound left-turn lane on Seaport Boulevard- Woodside Road and modify the traffic signal to provide a westbound overlap right-turn signal phase or a free westbound right-turn movement (and add emergency vehicle signal pre-emption to the traffic signal control). Finding D.ge: Addition of a second southbound through lane on Veterans Boulevard would improve conditions to an acceptable LOS D during the PM peak hour under Cumulative with Project Conditions. It should be noted, however, that a second receiving lane would need to be added to the US 101 on-ramp, and the ramp would need to be widened to accommodate merging with the ramp connection from eastbound Woodside Road. If the ramp is not sufficiently widened, merging congestion could degrade ramp operations, making this mitigation undesirable. Although provision of emergency vehicle signal pre- emption would not improve the general operating conditions at this intersection to an acceptable level of service, it would improve response time for emergency vehicles. Alternatively, a second westbound left-turn lane on Seaport Boulevard - Woodside Road could be added to the intersection, and the traffic signal modified so that westbound right turns would receive a green arrow simultaneous with southbound left turns, creating an overlap right-turn signal phase. This modification would require that southbound U-turns be prohibited at the intersection. Similar to the above alternative intersection modification, this measure would require the addition of a second receiving lane on the US 101 on- ramp, and in addition, would require modification to the structure supporting US 101. Such modifications to US 101 features could be infeasible. Again similar to the above alternative intersection modifications, while provision of emergency vehicle signal pre-emption would not improve the general operating conditions at this intersection to an acceptable level of service, it would improve response time for emergency vehicles. Instead of providing an overlap right-turn phase, it may be more desirable to provide a "free" westbound right-turn movement. The dedicated right-turn lane would require a receiving lane on Veterans Boulevard, and the turning movement would not be controlled by the traffic signal at the intersection. This would require widening Veterans Boulevard in the northbound direction by one lane, which is consistent with the City of Redwood City's traffic impact mitigation fee study. 8 U:\ProjectslAbbott Labs\Planning Commission - EIR and Entitiements\Statement of Overriding ConsiderationslAbbott - Statement of Overriding Considertions.doc
