The City of Asheville Stormwater Utility collects fees from property owners in Asheville in order to:

  • Plan for, improve and operate the stormwater system in an efficient and effective manner;
  • Adopt development policies and standards that prevent flooding, preserve streams and channels, and minimize water pollution without arresting new or infill development;
  • Develop detailed watershed plans that promote orderly growth;
  • Fully comply with federal and state regulatory requirements;
  • Educate the public about stormwater issues and involve them in stormwater initiatives; and
  • Implement utility fees to meet these needs in a fair an equitable manner.


Stormwater Billing Questions and Answers


 How is my Stormwater bill determined?

Stormwater fees are based on the amount of impervious area that exists on a parcel.  Impervious areas include all rooftops, gravel or paved driveways, parking lots, sidewalks not within the right of way, concrete patios, etc.  These surfaces impede the ground’s ability to absorb rain and therefore create water run off.


How do you measure the impervious area?

We use digital mapping software and aerial photography supplied by the state to take a bird’s eye snapshot of each parcel.  The software is able to identify most impervious areas.  We have a GIS team that is responsible for checking and correcting any inaccuracies.


In the following examples the areas in yellow and gray are identified as impervious.

Single Family Impervious Area Map
Impervious measurements = 2995.032517 sq. ft. = Tier 2


Non Single-Family Impervious area map
Impervious Measurements = 42997.858794 = 18 ERUs


The water from my property doesn’t run into the street.  Why am I charged a Stormwater fee?

The Stormwater fee is based on impervious area since that is what we are most accurately and efficiently able to measure.


My neighbor’s house is much larger than mine.  Do we pay the same amount?

Single-family homes are billed in three different tiers:

Tier 1 for impervious area up to 2000 square feet
Tier 2 for impervious area between 2001 and 4000 square feet
Tier 3 for impervious area of 4001 square feet and up


My tenant has the water account in their name, why isn’t the Stormwater fee 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 water 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.
