  • Residential Registration Form: The single family residential form is short and simple. Identify how you manage stormwater runoff from your roof and count the number of trees on your property that are at least 15 feet tall. Click here for further instructions.
  • Commercial Registration Form: The commercial registration is more detailed. You need to measure building footprints and any paved areas on your property. Your commercial utility bill includes the billed impervious area for each property as a reference. You will need to count the number of trees on your property that are taller than 15 feet.

Discount Calculators

Use the discount calculators to help determine how much of a discount you qualify for, and how much your discount improves as you increase your stormwater management. The commercial discount calculator is a Microsoft Excel document, so you must have MS Excel installed to use this calculator. The first Excel worksheet of the commercial calculator has the calculator instructions.

Residential Calculator: If you have a single family or duplex property, use the residential calculator. For residential properties, the discount is based on how much of your roof runoff you manage on your property. There are additional credits (not to exceed the maximum 100% discount on the on-site stormwater charges) for additional stormwater management options if you cannot manage all of your roof runoff.

Commercial Calculator: Download the commercial calculator if you have a multifamily (3 or more units), commercial, industrial or institutional property. For commercial properties, the discount is based on how much and how well you manage stormwater runoff from roof and paved areas. You will need to know your total square footage of impervious areas (roofs, paved areas, parking lots, pathways), what kind of stormwater management facilities you have on site, how much developed area each stormwater management facility manages, and the size of each stormwater management facility.

The questions on the calculators are similar to those on the registration form.
