These maps show the urbanized areas covered under the Phase II Municipal Stormwater Permits.
Ecology also included the following cities (within their incorporated boundaries) in the Phase II municipal stormwater permits. These cities have populations greater than 10,000, but densities less than 1,000 people per square mile:
The following maps illustrate the areas covered by Phase I (green hatching). Phase II areas in those counties are shown in yellow.
Ecology also provides maps that illustrate the federally-designated census urbanized areas (in red-hatching) and city boundaries (in yellow). Ecology used these maps in the process to identify Phase II jurisdictions. At a minimum, the Phase II permits must cover the census-defined urbanized areas (red-hatching). The federal Government will update these maps after the 2010 census.
