Prior to 2022, the management of the town’s state-mandated stormwater program was paid for through property taxes. That funding shifted to a Stormwater Utility Fee on January 1, 2022, which customers will see on their utility bills.

Most residential fees range from $1.50 - $10 per month, depending on your home’s amount of impervious surface (hard surfaces like your roof, driveway, and patio that do not allow rain to soak in). Commercial accounts and large residential accounts (greater than 5,400 sf of impervious area) are calculated with a different fee structure.

What is stormwater?

  • Stormwater is water from rain or snow that does not absorb into the ground. When not absorbed into the ground, stormwater moves to our streams and rivers and can carry pollutants.

Stormwater Fee Rates - Based on Impervious Surface

An Impervious Surface is a hard surface on a property that does not allow rain to soak into the ground such as, but not limited to, rooftops, carports, driveways, garages, walkways, storage sheds, parking lots, and patios.

Town roadways and sidewalks are maintained by the town, and not included in any resident or non-residential property's calculation.

There is a separate fee structure for residential and non-residential customers. Rates are generated by using a geographic information system (GIS) and aerial imagery to provide an equitable fee structure for all utility customers. Scroll down or click here to view the Stormwater Utility Fee map.

Residential Monthly Fee

Based on the total amount of square-feet of impervious surface on our property (not just your home's square-footage). Effective January 1, 2024, residential properties with greater than 5,400 square feet of impervious area assessed a stormwater fee per ERU, the same method used to calculate fees for non-residential properties.

Monthly FeeAnnual Fee
Tier 1 (400 - 1,500 sf)
Tier 2  (1,501 - 3,000 sf)
Tier 3 (3,001 - 4,000 sf)
Tier 4 (>4,001-5,400 sf)$10.00$120.00
Tier 5 (>5,400 sf)
$5.00 per ERU*Varies by property

*See non-residential monthly fee example below

Non-Residential Monthly Fee

Based on dividing the total impervious surface of the property by the Equivalent Residential Unit (ERU) (determined to be 2,700 sf) and multiplying that amount by $5.00. The Equivalent Residential Unit is the average square foot amount of impervious surface of residential properties in the town limits. This fee is for all developed non-residential property such as commercial, office/institutional, churches, apartment complexes, etc.

Monthly Fee = (Total Impervious Area / ERU) * $5.00

Impervious Surface AmountsMonthly FeeAnnual Fee
Small Property Example
4,400 sf(4,400 sf / 2,700 sf) * $5.00 = $8.15$98.00
Medium Property Example
66,800 sf(66,800 sf / 2,700 sf) * $5.00 = $121.85$1,462.17
Large Property Example
579,910 sf(579,910 sf / 2,700 sf) * $5.00 = $1,073.91$12,886.89
