Stormwater Billing


 How is my Stormwater bill determined?

Stormwater fees are based on a property’s impervious surface area such as rooftops, gravel or paved driveways, parking lots, private sidewalks (not within the right of way).  The more impervious surface, the more stormwater runoff flows from the property into the storm drainage system. Homes with the least amount of impervious surface area pay the lowest Stormwater fee.


My tenant has the water account in their name, why is the Stormwater fee not on their bill?

The City’s Stormwater charter instructs us to assign the Stormwater fee to property owners specifically. In the case where the property owner also holds the account, we apply the Stormwater charge to the water bill. Commercial properties are different in that the Stormwater charter allows us, in certain circumstances, to assign the Stormwater fee to the tenant.

Impervious Surface


What is considered an impervious surface?

Impervious surfaces are hard surfaces that do not allow rain to absorb into the ground.


What is not counted as an impervious area?

Areas covered with grass, trees, and gardens are not included when measuring impervious surface area.


How is the size of impervious area determined for my property?

Impervious surfaces are identified and measured using digital mapping and aerial photography supplied by the state for each parcel.
