Memorandum May 19, 1994. Page 6 of retail peaks with the non -retail traffic flow in the area would determine if delay is greater than what is shown in Table 1. Proposed Site Access and On -Site Circulation Site access is proposed at two locations. The main access to the site aligns with the main signalized Wa1=Mart access: We had two main concerns with this. driveway. One concern is the proper alignment of the lanes in the Fontana Square driveway with the lanes in the Wal-Mart driveway. Based on the most recent site plan, which contains an enlarged drawing of the two driveways, it appears that the driveway aligns properly with the lanes in the Wa1-Mart access. However, if the project is approved; this will need to be monitored to ensure proper alignment once the project moves into the review of detailed construction plans and roadway improvement plans. The other significant concern with regard to this access is the limited amount of vehicle stacking space within the driveway and the potential for that to result in 1) on -site congestion and 2) County Road E congestion. To address this concern,we conducted a detailed analysis for. a signal cycle during which a peak demand to exit the site would occur. This is accomplished by averaging the amount of vehicles which would exit the site per signal cycle during the pm peak hour and multiplying that figure by 1.5 to account for non-random arrival. In this situation, the vehicles which do not fit into the left turn lanes in the driveway must wait in the east/west collector road. The on -site collector road will have two-way stop control yielding to inbound traffic coming from County Road E. The only time this could create a problem in the in -bound drivewayis if a driver attempts to turn into the driveway after the turn lanes are already full. The vehicle would end up sitting in the middle of the intersection blocking inbound turns to the west Most inbound drivers in this situation would not choose to wait, and would turn right instead, and get to the west side of the site via the parking lot. This is expected to happen rarely and would not block inbound traffic as far as. County Road E even if drivers chose to wait until the vehicle blocking the intersection was moved so they could turn left. The current site plan shows a separate eastbound right turn lane and a shared through/right easement turn lane in the collector road. On -site congestionat the north end of the main access is likely to be worsenedby the inside eastbound lane being able to make a right turninto the driveway. We recommend this lane be modified to an eastbound through lane only. The second access to the proposed project is at the west side of the site, aligned with future Arcade Street to .the. south. Our main concern with this access it that the existing section of County Road E between the railroad tracks and the driveway may not be wide enough to accommodate an eastbound left turn lane. County Road E tapers down to four lanes with a median east of the railroad tracks. As the project proceeds through City reviews, a determination should be made as to whether or not this is physically feasible and at what point the left turn lane would be necessary to preserve acceptable flow of eastbound through traffic.
