TJ KM Transportation Consu Itants Introduction and Summary Introduction This report presents the results of a traffic impact and circulation study for an Assisted Living Facility development proposed by Fountain Square Development West at 2808 EI Camino Real in the City of Redwood City, California. Figure I shows a map of the study area vicinity. Figure 2 shows the project site plan. The proposed project consists of redeveloping parcels in the southwest quadrant of the intersection of EI Camino Real and Oakwood Drive with a senior assisted living facility. Currently, the parcels include a jewelry store and an unoccupied restaurant on the EI Camino Real frontage, and a vacant lot on the southwest end of the site. The proposed project consists of demolishing the existing structures and constructing 45 assisted living units on the site, to accommodate a maximum of 60 residents and beds. According to the project site plan, a new driveway will be provided on Oakwood Drive approximately 225 feet west of EI Camino Real. New curb,gutter, and sidewalk will be constructed along the entire project frontage on Oakwood Drive and EI Camino Real, and pedestrian walkway connections between the project's building access points and the new public sidewalk on Oakwood Drive will also be provided. The project also proposes vacation of an existing easement that had been reserved for a possible right-turn lane on eastbound Oakwood Drive. This report includes an analysis of potential project traffic impacts, including the need for a right- turn lane on eastbound Oakwood Drive approaching EI Camino Real; pedestrian, bicycle, and transit conditions, both existing and with the proposed project; an evaluation of site external access and internal circulation; and the project parking supply and demand. Summary 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.
