The amount of impervious area on your property is determined through the use of a geographic information system (GIS), aerial photos, and satellite imagery. Images are taken of Durham that show the impervious surfaces on each property. A computer program is then used to calculate the amount of impervious area on each parcel. To view impervious area on your property visit the Stormwater Utility Fee Map.
