Storm Water Services Fees

Detached Single-Family Residential properties (one individual, detached, single-family home on a parcel) are in one of four billing tiers based on the property’s total amount of impervious surface.

Each property in the tier is billed the same amount.

  • Tier 1:  <2,000 square feet of impervious surface

  • Tier 2:  2,000 to 2,999 square feet of impervious surface

  • Tier 3:  3,000 to 4,999 square feet of impervious surface

  • Tier 4:  5,000 or more square feet of impervious surface

All other properties (commercial buildings; attached single-family homes such as duplexes, triplexes and apartments; multiple single-family structures on one parcel) are billed for the actual amount of impervious area on the property.

Impervious surfaces are hard surfaces that do not allow rain to absorb into the ground. The more impervious surfaces, the more stormwater runoff flows from the property into the storm drainage system.
