The Storm Drainage System—The Source of Storm Water and its Destination
Storm water is water from rainfall that flows over land into the City’s drainage system. The drainage system includes:
- Over 750 catch basins
- 50 manholes
- Over 12 miles of conveyance lines
- Over 8 miles of open ditches
In addition to this constructed stormwater system, NormandyPark includes parts of four creek basins and over 4 miles of stream channel in:
- Miller Creek
- Walker Creek
- Normandy Creek
- Des Moines Creek (drainage area only; no stream channel is in the city)
Stormwater runoff and groundwater affect water quality, water quantity, and habitat in these streams. This in turn affects fish, birds, and wildlife. There also is stormwater that flows directly into Puget Sound from areas of the city close to the marine shoreline.
Regardless of how it gets there, stormwater from Normandy Park influences the overall health of Puget Sound.
We Need Your Help
Everything that enters our constructed or natural drainage system finds its way into Puget Sound. Please do your part to preserve water quality and protect the environment for today and for future generations:
- Employ “natural yard care”:
- Never pour oil, antifreeze, or paint on the ground or into a storm drain.
- Dispose of household hazardous waste properly.
- Use commercial car washes or wash your car on the lawn to keep soapy water out of storm drains.
- Protect beaches and bluffs
- Use water wisely outside and inside your home.
- Car Wash Kits:
Storm drains convey water through our public stormwater system to the nearest stream, creek, and Puget Sound without treatment. It is important to keep vehicle washwater from entering storm drains. The SudSafe Car Wash Kit captures washwater before it enters the storm drain and pumps it to either a grassy area or sewer. You can now use a FREE Car Wash Kit available at City Hall. A $50 deposit is required for use. Detailed instructions are included in kit. Enjoy your Car Wash and know you are helping in keeping our creeks, streams, and Puget Sound clean.
- Direct rain water appropriately so it can percolate into the soil. (This may not be appropriate for homes at the tops of bluffs or steep slopes.)
- Become a better steward today – see Tips on How You Can Help Miller/Walker Creeks.
Thanks for doing your part to help keep the city of Normandy Park and Puget Sound clean, healthy, and beautiful!
