Wetlands may be excluded when the development results in high density pockets. •DF Density Factor-the appropriate percent built upon area divided by 100. S RA Road Area^the total impervious surface occupied by roadways. •OA Other Area-the total area of impervious surfaces such as clubhouses,tennis courts, sidewalks, etc. •No. Lots is the total number of lots in the subdivision. •BUA/Lot is the computed allowable built upon area for each lot including driveways and impervious surfaces located between the front lot line and the edge of pavement.
