TJ KM Transportation Consu Itants 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 intersection, but no crosswalk is provided across the south leg of EI Camino Real adjacent to the project site. In terms of bicycle facilities, the only available facilities in the project vicinity are roadways shared with motorized vehicles. However, no impacts to local pedestrian or bicycle circulation are expected to result from the proposed project. TJKM reviewed the project site plan to evaluate on-site circulation and access. The location of the single,full access driveway to be provided on Oakwood Drive in relation to the intersections at EI Camino Real and at Leahy Street is expected to be adequate. Internal circulation is also expected to be adequate in terms of parking circulation aisles and internal pedestrian and bicycle circulation. In terms of potential sight-distance for motorists exiting the new proposed project site driveway on Oakwood Drive, a field visit revealed adequate sight lines. TJKM recommends, however,that all landscaping along the project street frontage that is located in the line of sight of traffic approaching the project driveway in either direction shall be limited to plants with foliage no more than three feet above the closest adjacent curb elevation, or trees with canopy foliage no less than seven feet above the closest adjacent curb elevation. This measure is expected to address any potential visibility issues for motorists exiting the proposed project driveway. Finally, TJKM evaluated the proposed parking supply using data presented in Parking Generation, 4th Edition, published by the Institute of Transportation Engineers, to estimate the project's potential parking demand. The proposed project parking supply ratio of 0.6 spaces per unit would exceed both the average peak parking demand of 0.41 vehicles per dwelling unit and the 85ih-percentile peak demand of 0.54 vehicles per dwelling unit observed at similar Assisted Living facilities. Based on this analysis, the proposed parking supply of 27 spaces for the proposed 45 units in the project would be adequate to accommodate peak parking demand on-site.
