7.A. - Page 193 <br /> Traffic Analysis Review of Proposed Rocketship Charter School, Redwood City, CA <br /> since the signal cycle there is two and a half minutes! Vehicles are unable to enter the <br /> intersection going northbound because of blockage ahead, and must wait with significant delays <br /> before they can pass through, one row of vehicles at a time. The level of service at this <br /> intersection cannot be calculated in a vacuum, or LOS C conditions would be the result, which is <br /> incorrect. In conclusion, it is not possible to bring more traffic through this intersection without <br /> creating an even worse impact on an already LOS F condition at the Woodside and Bay <br /> intersection. There must be mitigating improvements to this situation before more traffic is <br /> allowed to impact the intersection. Because LOS C conditions was reported in the Hexagon traffic <br /> study, which is incorrect, there was no discussion of mitigation. Caltrans would require a traffic <br /> operations study to be completed with microsimulation tools at a minimum, because these <br /> intersections along Woodside are so closely spaced, the HCM 2010 methods are entirely <br /> inappropriate and inaccurate. <br /> Traffic Study Review <br /> TRIP GENERATION. PRISM Engineering reviewed the key traffic study assumptions that affect <br /> impact, namely,trip generation of the project and trip distribution. Even though the traffic study <br /> acknowledges that five other Bay Area Rocketship Charter School locations are averaging am <br /> peak hour trip generation of 0.96 trips per student' and that this is the observed actual average <br /> trip generation, it may be that this average trip rate could be too low. This is considering the <br /> location of this proposed school site in an industrial location where possible pedestrian and bike <br /> safety and even transient concerns could motivate more parents to directly drive their children <br /> to school to help ensure their safety. <br /> TDM REDUCTIONS NOT REASONABLE. The report also mentions possible trip reductions in a <br /> Transportation Demand Management (TDM) program (see Table 7) up to nearly 50% lower <br /> volumes due to carpooling. We do not think this is a reasonable assumption to consider seriously <br /> as a potential mitigation because this kind of additional reduction is not being realized in the <br /> other Rocketship schools nearby(still averaging 0.96 trips/student). The Hexagon report stated: <br /> "The proposed TDM Program is expected to reduce the vehicle trips and parking demand <br /> generated by the Rocketship Redwood Academy thereby reducing the length of queue <br /> storage needed for drop-off and pickup operations." <br /> There are TDM Program assumptions discussed in the report indicating that 60 families would <br /> car pool based on financial incentives, resulting in 120 trip ends being subtracted from the total, <br /> and another 60 families would bike or walk to school also based on a $20/mo.financial incentive. <br /> What's wrong with this assumption is that the trip rate of 0.96 trips per student is already <br /> including carpooling with or without these incentives. We believe this trip rate for the school will <br /> 'See page 30 of Rocketship Redwood Academy—Traffic Study Report,Table 6. <br /> IMSM� Page 3 <br /> �_• ENGINEERING <br />
