Edgewood Surface Water Management

Quick Links: Surface Water Management Program (UPDATED MARCH 31, 2017)
As required by the Washington State Department of Ecology (DOE) and United States Environmental Protection Agency (EPA), the City of Edgewood must maintain coverage under the Western Washington Phase II Municipal Stormwater Permit. A key requirement of this permit is the City's Surface Water Management Program (SWMP) annual report to Edgewood's citizens and DOE:

What is NPDES? The Clean Water Act prohibits anyone from discharging "pollutants" through a "point source" into a "water of the United States" unless they have National Pollution Discharge Elimination System (NPDES) permit. This permit contains limits on what you can discharge, monitoring and reporting requirements, and other provisions to ensure that the discharge does not hurt water quality or people's health. In essence, the permit translates general requirements of the Clean Water Act into specific provisions tailored to the operations of each person discharging pollutants.

Every city in Western Washington is required to participate in the NPDES program, produce the documents (linked above) annually and make them available to the public. For answers to common questions about the NPDES permit and program, visit the US EPA's website. A brief overview about storm and surface water services and programs is available here.

Site Development Regulation Update

To maintain permit coverage and stay in compliance with State and Federal law, the City Council recently adopted Ordinance 16-0482:

  1. Updating Edgewood Municipal Code (EMC) as directed by the Phase II Permit's Section S5.C.4 (particularly subsections a and f)
  2. Adopting the 2015 Pierce County Manual (DOE equivalent) for surface water design and maintenance standards
  3. Making Low Impact Development (LID) the preferred approach to site development by incorporating and requiring LID principles and BMPs

In summary, there is a growing movement toward Low Impact Development (LID) stormwater management techniques in the region. LID's purpose is to limit disturbance of the natural environment's stormwater management ability to the maximum extent practicable, while still allowing for development in accordance with the Growth Management Act. While it requires more forethought and planning, LID is often made into an amenity of new developments and can be quite desirable to a growing population of environmentally-conscious citizens. To comply with DOE permit requirements, the City of Edgewood must make LID the preferred approach to stormwater management, to the maximum extent feasible, and educate citizens about the benefits of using LID in development.

The City Council has adopted Ordinance 16-0482 at the November 8, 2016 Regular Council Meeting, setting an effective date of November 15, 2016.  A table summarizing the adopted changes can be found here.  Updated informational handouts are currently being developed and will be published on the website soon.  If you have any questions, please contact Jeremy Metzler, PE – Senior Engineer at jeremy@cityofedgewood.org, or by phone at (253) 952-3299 x114.

Small changes can make a big difference. Here are some suggestions of what you and your family can do:
  • 10 ways to improve the quality of stormwater runoff (brief handout) - simple things you can do at home.
  • Washing your car at home can contribute to surface water pollution, and here's how. Instead, consider going to a local car wash, or try to wash your car in a grassed area that doesn't drain directly to the stormwater system.
  • Think Twice before using pesticides on your property.
  • Try controlling pests and weeds using Natural Lawn Care techniques.
  • Plan Before You Plant - Think sustainable landscaping!
  • Learn how mulch is important in creating healthy soils.
  • Follow these simple tips on how to Water Wisely.
  • Use these water-saving tips to save $100's and 1,000's of gallons of water in the summer with a garden makeover.
  • Check the Washington State Department of Ecology's website to find out what you can do to protect Washington's waters!
  • Pierce County has some great options for Recycling and Disposal of Household Hazardous Waste.

FREE Fish-Friendly Car Wash Kit
Are you planning a fundraising car wash, or are you a business owner who  allows fundraising car wash events on your property? Did you know that car wash events cause surface water pollution?

Good News: Edgewood has a FREE Car Wash Kit (for use at events held within City limits).

Everything you need is included in the kit, except the phosphate free, biodegradable soap, sponges, towels - and your volunteers, of course! An application and signed agreement is required to check out the kit. Contact City Hall at (253) 952-3299 to find out how to borrow the kit for your event.

Using the car wash kit helps to protect our lakes, streams, and Puget Sound. For more information about impacts of pollution on Puget Sound, visit the Washington Department of Ecology's website.
