TJ KM Transportation Consu Itants 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 on the existing one-lane eastbound approach, where 35.0 seconds is the LOS C/D threshold, clearly meets the City's acceptable LOS D standard. The a.m. peak hour 95ih-percentile queue length of approximately 210 feet with only one eastbound approach lane under Existing plus Proposed Project Conditions is not expected to block the project driveway. Delays and queues on eastbound Oakwood Drive during the other peak periods would be shorter than during the a.m. peak hour. These results do not appear to justify widening Oakwood Drive to add an eastbound lane. Additionally, reduced delays and queue lengths with an additional eastbound lane on Oakwood Drive approaching EI Camino Real could attract more drivers to use this intersection as part of a °short-cut" route, which is a major concern of residents of the adjacent neighborhood. Based on these findings, TJKM recommends that 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. Local Residential Street Traffic Volume Analysis Based on the existing daily and peak hour traffic volumes collected on Oakwood Drive east of Leahy Street, and the net additional project trips expected to use Oakwood Drive west of the project driveway as shown on Figure 4, TJKM determined the percentage increases in traffic volumes expected with the project. Daily project trips added were determined using the net increase of I 24 daily trips generated by the project shown in Table III and the 20%traffic distribution on Oakwood Drive west shown in Figure 4. Table V shows the results for the total traffic volumes in both directions on Oakwood Drive east of Leahy Street. As shown in the table, the project would result in traffic volume increases of approximately one percent on Oakwood Drive east of Leahy Street. Westerly of the Oakwood Drive/Leahy Street intersection, the project trips are expected to be distributed among multiple streets in the neighborhood and the resulting increases in traffic volumes would be similarly small percentages of existing volumes. 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. Table V: Oakwood Drive—Traffic Volume Increase with Project Time Period Existing Volume Project Tri�ps Added Percent Increase Daily 2,950 25 I% A.M. Peak Hour 35 I 2 I% School P.M. Peak Hour 230 2 I% P.M. Peak Hour 263 3 I% Project Transit Circulation TJKM reviewed the proposed project in terms of its potential effects on local public transportation. Some of the 25 employees of the project could ride public transportation to commute between their homes and the project site. The resulting additional transit passenger trips during peak hours would be a small number, and as a result, no impacts are expected from the proposed project 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.
