The city was designed as a National Pollutant Discharge Elimination System (NPDES) II city in January, 2007. The City was reissued a NPDES Permit on August 1, 2012. To comply with the permit, effective December 31, 2016, the City has revised development codes to:

• Make Low Impact Development (LID) the preferred and commonly-used approach to site development
• Adopt the Department of Ecology 2014 Stormwater Management Manual of Western Washington
• Reduce thresholds triggering stormwater controls to 2000 square feet of hard surface area of 7000 square feet of land disturbance.

The purpose of these standards and requirements is to improve water quality in all of the streams and local water bodies, and to control connections to the city's stormwater system.

The revised site development related ordinances were approved by the City Council on December 20, 2016, and have been incorporated into the January 2017 edition of Urban Service Standards and Guidelines.

Stormwater Source Control Ordinance Development

The City of Port Angeles is building a regulatory source control program that will require businesses to take measures to stop water pollution before it enters the stormwater system. The development of this program is a requirement of the Department of Ecology’s Western Washington Phase II Stormwater Permit. Learn more about the proposed ordinance and provide your feedback.
