Application for a Service Charge Adjustment – City of Bainbridge Island – Public Works

a
Decks: As long as a deck allows rain water to pass through it, to be readily absorbed by the ground below, it does not
need to be included as impervious surface. As soon as the ground under the deck is covered with an impervious
material, such as plastic sheeting or concrete for example, the deck would then be counted as impervious area. The
use of a pervious ‘weed block’ type of matte would allow the deck to remain excluded from calculations. Of course, if a
roof is erected over the deck, the roof area, out to the eaves, is impervious area.
b
Buildings or structures: Include all square footage of all roofed areas, including covered porches.
c
Driveways and Parking: Include all surfaces, including: gravel, asphalt, or concrete. Indicate type and sf of each surface.
d
Other: Include sport courts, swimming pools, or any other unroofed surface that sheds water.
f
“Low intensity development” means any development, excluding single-family, which creates or has existing impervious
surfaces that cover less than 15 percent of the parcel.
