Reducing Your Stormwater Utility Fee

Credits for installing engineered Best Management Practices (BMPs) are available for non-residential properties. Most properties that install stormwater BMPs receive a reduction of 37.16% for the area of the property that flows to the BMP.

In order to receive credit the BMP must (at a minimum):

  1. Be designed (and signed) by a licensed, professional engineer.
  2. Be sized to capture at least the first 0.5” of runoff.
  3. Have annual, documented inspections by the property owner, licensed professional engineer, or other qualified individual.
  4. Be maintained as needed based on the annual inspections.

Additional water quality benefits including temperature reduction, habitat creation, runoff rate control are preferred, if possible.

The best thing you can do to reduce your stormwater fee:

  1. Reduce your impervious surface. Since stormwater fees are based on impervious area, simply reducing the impervious footprint of the property is the single biggest thing you can do to reduce your stormwater fee. Vegetating gravel areas, removing excess concrete and blacktop parking areas, and even removing vacant buildings all can quickly reduce your stormwater fees.


Note: The City of Duluth recommends contacting the Stormwater Utility Office 218-730-5200 (or submit the billing request form) before proceeding with efforts to reduce your stormwater fee as the property may already be receiving credit.
