Impervious Surfaces

All residential permit applicants that propose adding any type of improvement (New Home, Additions, Accessory Buildings, Pools, etc.) must add to their site plan the individual square footage for all impervious surfaces. The footprint of the main structure, pools, pool decks, additions, accessory buildings, driveways, parking, walkways and any other flat work must be accounted for.

Impervious: Not allowing entrance or passage. Often referring to a surface that will not allow rain water to pass through.
