Storm & Surface Water Drainage Utility System
The Edmonds stormwater drainage utility system is comprised of catch basins, ditches, pipes, and other structures that flow into streams, lakes and wetlands, all of which outfall to the Puget Sound or Lake Ballinger.  The Engineering Division is responsible for compliance with the State's Western Washington Phase II Municipal Stormwater Permit (NPDES) including review of new building or redevelopment projects for compliance with the Edmonds stormwater code, and long range planning as it relates to the Edmonds stormwater code, and design and construction management of public storm system improvements.  City crews perform maintenance and repairs to the entire system to reduce flooding, improve water quality and preserve the environment.
Lake Ballinger Water Level

The Lake Ballinger monitoring system provides Citizens and City staff with 24-hour access to the current lake level. The data is updated every 5 minutes.

The yellow alert level is set at elevation 278.61 feet. This elevation corresponds to a lake level that is 1 foot below the lowest finished floor elevation of any home on the lake. When this lake level is reached, residents on the lake with homes close to the shoreline should begin to take precautions.

The orange alert level is set at elevation 279.11 ft. This elevation corresponds to a lake level that is 6 inches below the lowest finished floor elevation of any home on the lake. When this lake level is reached, residents on the lake with homes close to the shoreline should definitely begin to take precautions.

Elevation 279.61ft corresponds to the lowest finished floor elevation of a home on the lake, or red alert.

Sand and bags are available to residents at the Operations & Maintenance Center of the Edmonds Public Works & Utilities Department located 7110 210th St SW between the hours of 7:00am to 4:00pm. Call ahead at 425-771-0235.

Residents on the lake will not receive emails or other communications regarding the lake level. This webpage is intended to provide residents with this information whenever needed. All elevations are reference to the following datum: National Geodetic Vertical Datum of 1929 (NGVD29).

Report a Spill and Illicit Discharges


Do you see signs of a pollutant spill in or near a storm drain or water body?

During normal working hours please contact the Public Works Department at 425.771.0235

For AFTER HOURS EMERGENCIES: Call 911 - the operator will dispatch a utility crew member as required.

Illicit Discharges - Illicit discharges are regulated by Edmonds City Code section 7.200.  Pollutants may include, but are not limited to: paints, varnishes, and solvents; oil and other automotive fluids; pesticides, herbicides, and fertilizers, hazardous substances and wastes; sewage, fecal coliform and pathogens; dissolved and particulate metals; animal wastes; wastes and residues that result from constructing a building or structure; noxious or offensive matter; and non-hazardous substances or materials that may cause or contribute to pollution.

Notification of Spills - The person or company responsible for the premises or operation in which a known or suspected release of materials has occurred shall take all necessary steps to ensure the discovery, containment, and cleanup of such release. 

Stormwater Utility Development Requirements

The Engineering Division reviews development projects for compliance with City stormwater requirements.  These requirements are intended to ensure that the construction of a project and the resulting developed site do not create flooding or erosion impacts to public or private property and do not negatively affect the quality of surface water bodies.  The most recent code revision was in 2010.  This revision update included changes to ensure compliance with the Western Washington Phase II Municipal Stormwater Permit, issued by the Department of Ecology.  The following resources may be helpful when designing your development project. 
Edmonds Community Development Code (ECDC) - ECDC 18.30 is the stormwater chapter of the development code.  The requirements of the chapter are minimum requirements.  Compliance with all applicable federal, state and local laws and regulations is still required.  
Stormwater Code Supplement (5.59MB) - The stormwater supplement was adopted as Exhibit A to ECDC 18.30.  The Supplement provides direction for implementing the stormwater management requirements of ECDC 18.30.      
water-01_smLow Impact Development (LID) - The City of Edmonds strongly encourages the implementation of low impact development techniques whenever feasible.  For more information on LID please visit the Sustainability section of our website by clicking on the link to the right.


Phase II Municipal Stormwater Permit Compliance

The Western Washington Phase II Municipal Stormwater Permit (Permit), issued by the state Department of Ecology, covers 80 plus cities, including Edmonds. The Permit authorizes the discharge of stormwater runoff from municipal stormwater systems into the state’s surface waters (i.e., streams, rivers, lakes, sounds, wetlands, etc.) and groundwater as long as municipalities implement Permit-specified actions and activities known as Best Management Practices (BMPs) to protect these receiving waters. The City of Edmonds’ Public Works Department, Engineering and Storm Divisions run a comprehensive program to ensure compliance with the Permit requirements.

The permit requires that all affected municipalities create and implement a Stormwater Management Program (SWMP), which addresses the five required program elements.  These elements are:

·         Public Education and Outreach
·         Public Involvement and Participation
·         Illicit Discharge Detection and Elimination (IDDE)
·         Controlling Runoff from New Development, Redevelopment, and Construction Sites
·         Municipal Operations and Maintenance (O&M)

Each of these required elements has different implementation schedules but all program elements must be fully implemented within the five-year permit term.

Each Permittee must annually prepare written documentation of the SWMP, called the SWMP Plan.  This Plan is intended to be a forward-looking document describing the set of actions and activities (BMPs) the Permittee intends to complete in the upcoming calendar year to comply with the Permit.  A link to the most current SWMP Plan is below:

         2014 Stormwater Management Program (SWMP) Plan

The Permit also requires that the City of Edmonds provide an annual report to the Department of Ecology to document its compliance actions. Per Section S9 of the Phase II Permit, the initial annual report for the current Permit will be submitted to Ecology no later than March 31, 2015. When available, a copy of this annual report will be posted on this page. Annual reports for previous years are available upon request.

City - City crews perform maintenance activities on the entire storm drainage system, including inspection and cleaning of catch basins, street sweeping, emergency flooding response, creek maintenance, inspection and monitoring of private stormwater detention systems. 
Private Property Owners - Private property owners are responsible for properly maintaining the stormwater infrastructure on their property to ensure it operates as designed.  The City has developed an inspection program to ensure private property owners are properly maintaining their stormwater systems.

The Edmonds storm drainage system is composed of streams, lakes, wetlands, storm detention sistes, pipes and ditches - all of which outfall to the Puget Sound.  City crews perform maintenance and repairs to the entire system to reduce flooding, improve water quality and preserve the environment.  These maintenance activities include inspection and cleaning of catch basins, street sweeping, emergency flooding response, creek maintenance, inspection and monitoring of private stormwater detention systems, and minor capital improvement project construction.
