Peregrine Pass May 24, 1999 page 7 Impervious surface: A planned development allows for flexibility. Under the proposed plan, the road pavement will not be as wide as in normal developments. This reduces the amount of impervious surface, which allows more infiltration of water. It also is possible to have shared driveways. This would further reduce impervious surface. Roads, access and safety: One lot will access 12th Ave. The other nine lots will access the internal cul de sac. The roads can handle additional traffic generated by nine homes. In any development, each access onto a road is a potential safety concern: more access points mean increased probability of accidents. The proposed plan prevents numerous driveway accesses onto 12th Ave. and Holly Drive. Eight out of nine lots will access 12th Ave. via a new cul de sac road. Thus, instead of nine new driveway accesses, there will be one driveway access (Lot 9) and one road access. Density, Lot Sizes: Gross density is 1.21 units per acre. Net density, counting only the uplands, is 1.53 units per acre. The same number of lots would be possible under R -1X zoning. The R1 -X minimum is 12,825 sf buildable land. All nine lots meet the R1 -X minimum. The greatest departure from normal zoning is in the lot widths. Minimum lot width for R -1 is 80 feet, for R -1X is 90 feet. The lot widths on the revised plat are as follows: All but two lots meet the R -1 width, and these come to 86% and 91% of it. Four lots are less than the R -1X width, but two are over 90% of it, one is 81 %, and one is 77 %. The lots increase in width farther from the road frontage. Minimum side yard setbacks are met (10 ft.). The lots are arranged to allow for the environmentally friendly features described above, and this justifies the widths that are less than standard zoning. Minimum house footprint sizes of the R -1X zoning district will be a condition of approval. lot width (ft.) % of R -1 (80 ft.) % of R1 -X (90 ft.)
