4.16.2.2 Queuing All traffic entering and leaving the project site must travel through the El Camino Real/Oakwood Avenue intersection. Based on the current roadway configuration there are two movements,right- turn from eastbound Oakwood Avenue and left-turn from northbound El Camino Real,that could experience queuing backups due to increase traffic trips. In addition,there is currently an easement on the project site that would allow for the construction of a designated right-turn lane on eastbound Oakwood Avenue. There are currently no designated turn lanes eastbound on Oakwood Avenue. The proposed site plan would require the vacation of the existing easement. For these reasons,the traffic analysis addressed the queuing for these turning movements. Northbound EZ Camino Real to Westbound Oakwood Avenue The left-turn queue on El Camino Real was studied under exiting plus project conditions for all three peak hours. The analysis compared the 95�'percentile queue lengths with the left-turn storage length provided. The northbound,left-turn queue on El Camino Real is 200 feet. With implementation of the proposed project,the 95�'percentile PM Peak Hour queue length(the longest queue of the three peak hours)would be approximately 150 feet. Therefore,the existing left-turn lane configuration is adequate to accommodate the increase in eastbound turning movements from El Camino Real. Eastbound Oakwood Avenue to Southbound EZ Camino Real Table 9 below shows the 95�'percentile queue lengths for the three peak hours without a designated right-turn lane.

The AM Peak Hour queue of 211 feet would not block the project driveway or significantly interfere with traffic operations. With implementation of the proposed project,the delay on the eastbound approach of Oakwood Avenue is expected to be 363 seconds. This falls within the City's acceptable LOS standard. If a designated right-turn lane was constructed,it would reduce the AM Peak Hour delay on the eastbound approach by approximately 11 seconds. The minimal improvement to the overall delay is not sufficient enough to warrant a designated right-turn lane, even with project traffic. The vacation of the existing easement and operation of the proposed project will not significantly impact intersection operations or cause excess right-turn queues on eastbound Oakwood Avenue. The project will have a less than significant queuing impact at the study intersection.
