TJ KM Transportation Consu Itants Conclusions and Recommendations TJKM has reached the following conclusions regarding the Assisted Living Facility development proposed by Fountain Square Development West at 2808 EI Camino Real: • The proposed project is expected to generate a net increase of approximately 9 a.m. peak hour vehicle trips (6 inbound, 3 outbound), I 2 school p.m. peak hour vehicle trips (2 inbound, I 0 outbound), and I 6 commute p.m. peak hour vehicle trips (9 inbound, 7 outbound). • Under Existing Conditions, the study intersection of EI Camino ReaUOakwood Drive/Dumbarton Avenue is operating at level of service (LOS) C or better during the peak hours. These existing service levels meet current City of Redwood City LOS standards. • Under Existing plus Proposed Project Conditions, the study intersection of EI Camino ReaUOakwood Drive/Dumbarton Avenue is expected to continue operating acceptably at LOS C or better during all peak hours,just as under Existing Conditions,with minor changes in average vehicle delay. The 95ih-percentile left-turn queue lengths on northbound and southbound EI Camino Real during the peak hours with the additional project trips would be accommodated within the available left-turn lane storage lengths. Therefore, no mitigations due to project traffic are necessary at the study intersection. • TJKM also analyzed the expected 95ih-percentile queue lengths for the peak hours under Existing plus Proposed Project Conditions assuming only one lane for eastbound Oakwood Drive approaching EI Camino Real, which is the same lane configuration as existing conditions. The project's impact on peak-hour queue lengths would be less than significant. The a.m. peak hour would have the longest 95ih-percentile queue length of approximately 210 feet, which is not expected to block the project driveway. Although an additional eastbound lane on Oakwood Drive approaching EI Camino Real would reduce the a.m. peak hour delay and queue length,the expected 36.3 seconds of delay with the existing one-lane eastbound approach, where 35.0 seconds is the LOS GD threshold, clearly meets the City's acceptable LOS D standard. Based on these findings, TJKM recommends that widening for a right-turn lane on eastbound Oakwood Road is not needed and the proposed vacation of an existing easement that had been reserved for such lane may proceed. • Based on the existing daily and peak hour traffic volumes on Oakwood Drive east of Leahy Street, and the net additional project trips expected to use Oakwood Drive west of the project driveway, TJKM determined the percentage increases in traffic volumes expected with the project. Because the increase in local residential street volumes would be less than five percent, the project impact on these streets would be less than significant. • In terms of potential effects on local public transportation, some of the 25 project employees could ride public transportation to commute. The resulting additional transit passenger trips during peak hours would be a small number, and no impacts are expected on local SamTrans services, including Routes 390 and KX that stop on EI Camino Real at Oakwood Drive adjacent to the project site. As part of the project, additional requests for Redi-Wheels paratransit service for project residents may occur. However,this is not expected to adversely impact existing Redi-Wheels service. • In terms of pedestrian facilities, the project will construct new sidewalk along the entire project frontage on Oakwood Drive and EI Camino Real, and internal pedestrian walkway connections between the project's building access points and the new public sidewalk on Oakwood Drive will also be provided. Existing crosswalks with pedestrian signal indications are provided across Oakwood Drive, Dumbarton Avenue, and the north leg of EI Camino Real at their signalized Dra ft Report— Tra�c Impad Study for Assisted Living Facility Development at 2808 EI Camino Real Page 19 in the City of Redwood City March 12, 2012
