Im Centre Drive. This recommendation is based on the assumption that the calculated outbound queue length under buildout conditions Is shorter than the evening queues that were observed. In addition, the Keep Clear recommendation assumes the existing inbound queues onto Xerox Centre Drive are negligible to the point that the presence of a Keep Clear area would both be obeyed by existing inbound vehicles and would not result In inbound queues reaching back to Cabrillo Park Drive. An unintended consequence of this Keep Clear treatment is the extension, rather than the remedlation, of the existing morning inbound queue. Keeping The Madison access area on Xerox Centre Drive clear of vehicles would necessitate existing vehicles currently queued in this access area to start queuing farther away from the Xerox Centre parking garage entrance and closer to Cabrillo Park Drive. This increases the potential for Inbound queues to interfere with traffic on Cabrillo Park Drive. Based on LSA's on-site field observations, a Keep Clear sign will not solve the problem with the evening outbound queue that stretches back from Cabrillo Park Drive into the existing parking structure and that would likely block any outbound Madison -related vehicle from entering the eastbound queue. The effect of the Keep Clear sign on existing inbound queues that already reach to the midpoint of Xerox Centre Drive has not been assessed and may result in Inbound queues extending to Cabrillo Park Drive. LSA agrees with the report's note of the complimentary travel patterns between The Madison and the Xerox Centre building, with future residents leaving while existing workers enter in the morning and vice versa in the evening. However, the proposed complimentary travel patterns do not help mitigate how the existing observed queues would block any number of vehicles, however few, from effectively exiting The Madison. Further review of the site plan finds that there is a more effective access treatment that can mitigate the issues raised in this review while also reducing northbound traffic on Cabrillo Park Drive in the evening through the elimination of the only vehicle conflict point between The Madison and existing Xerox Centre Drive traffic. This conflict point is illustrated below in Exhibit 1. Th.
