Stormwater code and manual
Clark County received a new National Pollution Discharge Elimination System (NPDES) permit that is effective August 1, 2013 through July 31, 2018. The Washington Department of Ecology permit is part of the federal Clean Water Act. Clark County has operated under such a permit since 1999.
This permit, among other things, specifies new regulations for managing the quantity and quality of stormwater discharged from the county’s stormwater system. To comply with the permit, the county will update applicable development codes, such as and 40.385 Stormwater and Erosion Control, and design manuals.
Clark County will pursue updates that are:
- Flexible and tailored to multiple project types, including making Low Impact Development (LID) the mandatory approach for stormwater management in site development.
- Compatible with other state and local regulations to protect the environment and support an economically vibrant and liveable community.
For this project, refer to the follow sections for more information:
