Surface Water Management

“Residents of this region enjoy a way of life centered around the waters of Puget Sound featuring…...irreplaceable aesthetics, and other activities, all of which to some degree depend upon a clean and healthy marine resource.”

-Puget Sound Water Quality Protection Act, 1996

 

Background



       SWM1
In 1996 the Washington State Legislature established the Puget Sound Water Quality Management Program that clearly delineates federal, state and local action necessary to protect and restore the biological health and diversity of Puget Sound. The plan includes the framework describing various governmental roles for enhancing recreational opportunities, and restoring a balanced population of indigenous shellfish, fish and wildlife. Using this road map, the City of Maple Valley developed a long term strategy that implements the goals outlined in the Puget Sound Water Quality Management Program.

  • Public Education/Public Involvement
  • Illicit Discharge Detection and Elimination
  • Construction Site Stormwater Runoff Control
  • Post Construction Stormwater Control

Additional Information

 


GOATS ARE BACK IN THE CITY

 

2015 Goat Picture 

As an eco-friendly alternative, goats will return to the City of Maple Valley to graze their way through 36 of the City’s Stormwater Ponds (Attached Pond Lists). The goats eat all vegetation in their path and can easily reach areas not accessible by mowers or other mechanical equipment due the steep hillsides and uneven ground. Also, goat manure is a natural fertilizer and adds nutrients to the soil. They will arrive on July 6 and return home in late October 2015.

The use of goats to “mow” the City’s Stormwater Ponds has drawn interest and positive feedback from local citizens and kids since 2012. For more information, contact Ken Srilofung, SWM Manager, City of Maple Valley; Public Works Department (425) 413-8800.
