Determine Fee – Impervious Analysis
1. Use town data on driveways, parking lots, buildings, outbuildings, decks and pools. 2. Match impervious layers to the associated parcel using Arc GIS 10.1 3. Calculate the area (square feet) of impervious coverage per parcel4. Divide impervious (sq ft) by the total parcel area (sq ft) to derive the percentage of
impervious coverage per parcel5. After sorting the parcels by land use (multi-use, residential, commercial, etc)
calculations were made to derive the average impervious coverage by land use.

Based on a typical Single Family Residential home’s impervious area ( = 1 Equvalent Residential Unit [ERU]).
Fees for Commercial, Industrial and possible larger Residential parcels (Two-Family, Multi-Family, etc.) are calculated relative to ERU.
