With respect to external circulation, according to the applicant's <br /> Transportation Impact Report (attached), the traffic volume projected to be <br /> generated by the development is 1,330 vehicles per day (133 lots, 10 trips <br /> per day). 1984 vehicle counts mark the Average Daily Traffic on Weaver <br /> Dairy Road at 4,187 vehicles. Weaver Dairy Road's capacity is 10,000 ADT. <br /> The applicant's report does not account for developments that have been <br /> approved but not yet constructed. These approvals will represent a signif- <br /> icant increase in traffic volumes in the Weaver Dairy Road corridor. List- <br /> ed below are projects recently approved in this area.

The analysis concluded that the first two of these inter- <br /> sections are functioning and will continue to function well, accounting for <br /> approved developments. The Erwin Road/15-501 intersection, however, will <br /> be over-capacity once all these developments are constructed. <br /> The applicant estimates that the proposed subdivision would generate an <br /> additional 15 peak hour movements through the Erwin Road/15-501 intersec- <br /> tion. <br /> Staff Recommendation <br /> We recommend that the Planning Board recommend to Council approval of <br /> Preliminary Plat for Chandler's Green subject to the conditions on <br /> Resolution A. Two remaining concerns are the need of serving part of the <br /> subdivision with pump stations, and the potential traffic impacts of the <br /> subdivision. Resolution B would deny the application on these grounds. <br /> -3- <br />
