What is my SWU fee based on?

The utilities’ rate structure is based upon the amount of impervious surface area within each parcel or equivalent service units (ESU).
A $45.00 basic service charge per ESU, per year shall be levied against each developed parcel within the service area.
The following are examples of how ESU's are calculated and applied within the service area:

  • Single family residence = one(1) ESU.
  • Duplex = one(1) ESU.
  • Tri-plex / Four-plex = two (2) ESUs.
  • For all other parcels: 

# ESUs = the total square feet of impervious surfaces divided by 2750 square feet. (2750 square feet is the approximate surface area of an average residential rooftop and driveway)

  • No developed parcel shall contain less than one (1) ESU.
  • Undeveloped parcels do not contain ESU’s.
  • Douglas County and East Wenatchee pay for their impervious areas, including streets, roads, trails, and parking lots..

Notes:

  1. Qualified low-income senior citizens and disabled persons may be eligible for a discount.
  2. In addition storm water facilities designed to accept runoff may be eligible to receive a storm water utility credit.
  3. Rate structure is current as of March 25, 2016.

What do I get from the Storm Water Utility?
The SWU attempts to assure that there will be long term funding to pay for construction, maintenance and repair of storm water facilities.
Douglas County’s Comprehensive Flood Hazard Management Plan identifies many capital improvement projects in the Greater East Wenatchee area aimed to mitigate chronic flooding problems. Multiple projects have been completed to date such as Canyon B channel stabilization, drywell installation and repair in East Wenatchee and the Fancher Heights area, Canyon A culverts at Eastmont/3rd St SE, construction of detention basins at 4th St SE, 10th St. SE, 23rd St NE & 35th St NE, obtaining capacity in a storm water conveyance system, 27th Street NW to the River.

Stormwater utility funds pay for improving and maintaining the storm drainage system. Improvements to the overall drainage system may have more direct benefits to some, but that does not impact the fairness of the rate or that we all benefit from stormwater management. While your property may not be physically connected to the drainage system, the storm water utility improves and maintains upstream facilities which in turn protects your property. Everybody benefits from the maintenance and improvements provided by the stormwater utility, through an improved environment, better access to roads during storm events, and reduced flooding during abnormal years. Maintenance of the storm drainage system helps to ensure the safety and reliability of the road system within the Storm Water Utility Area. Every developed property benefits from maintenance and improvements to the storm drainage system.

Wenatchee Valley Stormwater Technical Advisory Committee
In February of 2007, the Washington State Department of Ecology issued the Eastern Washington Phase II Municipal Stormwater Permit to the City of Wenatchee, Chelan County, Douglas County and the City of East Wenatchee. This permit requires each jurisdiction to develop and implement a stormwater program with the goal of reducing the amount of pollution in stormwater.

To share resources and develop a consistent regional stormwater program, representatives from both cities and counties have been working together to meet the requirements of the permit. This group is called the Wenatchee Valley Stormwater Technical Advisory Committee (WVSTAC). Over the next five years the program will be developed and implemented. For the latest information regarding the regional stormwater program, please visit the WVSTAC page.
