Background:
The City of Tukwila has obtained coverage under a NPDES (National Pollution Discharge Elimination System) Phase II Municipal Stormwater Permit issued by the Washington State Department of Ecology. The NPDES is a federal requirement under the Clean Water Act that regulates stormwater and wastewater discharges to waters of the State. The permit requires that all affected municipalities create and implement a Stormwater Management Program (SWMP), which address five required program elements. These elements are:
- Public Education and Outreach
- Public Involvement and Participation
- Illicit Discharge Detection and Elimination
- Construction Site Run-Off
- Operations and Maintenance of Post Construction Stormwater Facilities
Each of these required elements has different implementation schedules but all program elements must be fully implemented within the five-year permit term.
Current NPDES Activities:
NPDES Stormwater Education and Outreach Program Survey
The City’s National Pollutant Discharge Elimination System (NPDES) Phase II general permit requires that the City measure its
residents understanding of the City’s stormwater system. To meet this requirement,
The 2010 Stormwater Management Program (SWMP) included a 15 question survey with the utility bills of 1,000 randomly selected
residents with a zip code of 98168.
The 2011 SWMP included a partnership with the City of Kent in which Hebert Research Inc. conducted a Stormwater Community phone
survey of 204 randomly selected residents. 100 of these phone surveys were in Tukwila with a zip code of 98168. The remaining
phone calls were given to Kent residents.

Residential surveys will be performed annually and posted on this web page.
GIS Mapping - The City began a Geographic Information Systems (GIS) mapping project in 2003 and just completed mapping
area seven of eight. Mapping includes all receiving water body outfalls, all public surface water pipes 8” and larger and information
such as pipe invert, material and its condition. All GIS information is added to the City’s GIS Database and is instrumental in the
managing and development of our stormwater system. The GIS Database will continue to be refined as needed.
This GIS mapping has been made possible through the City’s Storm and Surface Water Utility fund and a Washington State Department of Ecology Capacity Grant.
SWMP Development - The City has completed the 2012 SWMP which describes the tasks and schedule for full implementation of the Phase II Municipal Stormwater Permit. The SWMP is a living document that will be updated annually. Surface Water Management staff are currently tracking, reviewing, and maintaining component information to continue with evaluating and updating each component of the SWMP.
