cmin Kimley-Horn �� and Associates,Inc. Review of the TOD Strategy EIR revealed that no significant impacts were created at the Interstate 880/Davis Street ramps or at the Davis Street intersection with Hays Street.Therefore only the Davis Street/E.14th Street intersection was previously documented as having a significant impact with the implementation of the entire TOD Strategy(not the subject San Leandro Tech Campus project).The following mitigation was included in the EIR: • "Convert outside southbound through lone to a shared through-right lone providing dual right turns southbound. This improvement, in combination with proposed improvements as identified in the TOD Strategy, would require widening of the west side of East 14th Street by 6-10 feet. This widening could occur when the block between Davis and Hays is redeveloped. With these improvements the intersection of East 14th Street and Davis Street would operate at LOS D or better(48.4 seconds of delay in AM and 54.4 seconds in the PM peak hour),and would result in a less-than-significant impact." Please note that this mitigation is not a requirement of the subject San Leandro Tech Campus project, and is understood to be accomplished through the Citywide traffic mitigation fees in combination with the development at the Davis/Hays Intersection. • Comment#2 The commenter notes that"significant"queuing is documented to occur along the westbound left-turn movement at the Davis Street/Alvarado Street intersections,and the northbound left-turn movement at the Davis Street/San Leandro Boulevard intersections. Davis Street/Alvarado Street The westbound left-turn queues were analyzed at this intersection and the project resulted in an increase in queue length from 164 feet in the Existing scenario to 212 feet in the Existing plus Project • plus SLB scenario.This is an increase of 48 feet. The existing storage length is 115 feet,so the existing queues already block the adjacent through lane. Although there is existing pavement for a double left- turn configuration,Alvarado Street does not have adequate width to receive dual left turns(single receiving lane). It is important to note that this Intersection operates at LOS B during the subject peak- hour. The analysis software used for this analysis(Traffix)is not designed to allow for advanced signal timing entry or modification. Nevertheless,as would be the case if other tools had been used(Synchro),simple adjustments to the signal timing parameters have been documented to lessen the subject queuing. Minor adjustments for the westbound left-turn's timing parameters results in a queue length of 171 feet,which Is only 7 feet longer than the 164 feet without the project. The overall LOS and delay for the • intersection goes from LOS B(19.3 seconds delay)to LOS C(22.3 seconds delay).As a result,this queuing(7-feet)is considered to be less than significant. Davis Street/San Leandro Boulevard The northbound left-turn queues at this intersection have an increase in queue length from 466 feet in • the Cumulative scenario to 665 feet in the Cumulative Plus Project scenario. This is an increase of 199 feet. The existing storage length is 230 feet,•so the Cumulative queues already block the adjacent through lane.The project's contribution of approximately 8 vehicles(4 vehicles per lane)to this substandard condition is considered insignificant and will be further reduced by the project's contribution to TOD Strategy Area improvements aimed at increasing transit use and reducing automobile trips. • San Leandro Crossings Page 2 of 3 Response to Caltrans'Comments February 20,2014 •
