First of all, there is existing parking saturation on Charter Street <br /> here, and specifically along the eastern curb of Charter Street along the project site frontage and <br /> beyond. The site plan shows an entry driveway that is angled at 45 degrees forcing an inbound <br /> movement coming from northbound Charter Street only. In other words, all project traffic must <br /> pass through the Spring Street/Charter Street intersection. All students in vehicles must travel <br /> northbound on Charter Street then enter the site just before Bay Road. <br /> All elementary schools have long arrival queue lines. There are no observable exceptions <br /> throughout the USA. This is because the <br /> majority of parents will drive their young <br /> children to school, and in particular in the Bay <br /> Area where this has been observed to be as <br /> high as 90% in San Francisco. This equates to <br /> Ai significant vehicle queues on the road serving <br /> the school driveway. An average elementary <br /> school is getting queue lines up to a quarter <br /> mile long (1320 feet, see photo to left). The <br /> distance between the project driveway and Spring Street is less than 600 feet. This means that <br /> when parents are arriving with their children, the vehicles will block all driveways long Charter <br /> Street for in and outbound traffic for all businesses, and far beyond Spring Street. This queue <br /> congestion typically takes place for about a half an hour. The only way to mitigate impacts to a <br /> local street is to provide adequate queue storage on the school site. It is interesting to note that <br /> if all Rocketship charter school parents arrived at exactly the same time, and with an average of <br /> 8 feet between cars 15 feet long, this distance of 23 feet multiplied by the 250 inbound cars <br /> calculates to a distance of 5,750 feet, or more than a mile. This is the amount of roadway <br /> occupancy that takes place with 250 vehicles in a queue. However,this queue has arrivals taking <br /> place over about a half hour period of time, lessening this length. <br /> 1�1)RISM3Page 6 <br /> -fir-►AENGINEERING-r <br />
