due to recreation space and street rights-of-way. This w o ao represent an increase of 43 units above the number which could be developed under the current R-2 designation and would represent a net density of 3 , 2 units per acre. The 92 additional units plus 177 existing or proposed lots would represent a total build-out of 269 units or 19 more than included in the calculation of excess capacity of the Wildwood pump station . The 19 additional units (210 GPD/unit) would use 3, 990 GPD of the excess pump station capacity, leaving 10,735 GPD for future development in the area. An obvious implication of retaining the existing zoning designation ( R-2) or a lesser designation ( R-3) is the excess capacity in the pump station would be increased. As an example, development at R-2 densities would result in a project build-out of 226 units or 24 units less than the 250-unit projection used in calculating excess capacity. At such a density, an additional capacity of 5, 040 GPD would result, increasing the projected station capacity from 14 ,725 GPO to 19 ,765 GPD. At an R-3 density, the projected station capacity would increase from 14,725 GPO to 16, 405 GPD, based on a total build-out of 242 units . ROADS/TRAFFIC The site would be served by access to NC 86, an arterial , via John Breckenridge Road, Walter Clark Drive and the proposed Oakdale Drive Extension ( upon construction) . The 1984 traffic count for NC 86 at its intersection with SR 1710 ( Old 110) is 7000 trips per day. John Breckenridge Road and Walter Clark Drive currently serve as sub-collector roads. The addition of ninety-two (92) dwelling units utilizing both these roads for access to N. C. Highway 86 would not adversely impact the service level of either of these roads. On the following pages, traffic projections have been shown for Sections 1- III of Wildwood Subdivision, utilizing existing zoning designations and existing or projected dwelling unit counts. Projections have also been shown for the proposed Section IV under three different zoning scenarios R-2 ( existing), R-3 and R-4 ( proposed) . The projections were based on an ITE trip generation rate of 10 trips/single-family dwelling/day and are summarized below for the major sub-collector roads.
