Low Impact Development

Sustainable development practices help balance growth with protection of our region's valuable resources.

Low Impact Development (LID) is an approach to land development that focuses on how water enters a site, is stored on-site, and leaves a site. Land development practices that incorporates LID:

  • Minimize impervious surfaces, such as roads and driveways, that water can’t percolate through
  • Protect and enhance native vegetation and soils
  • Manage stormwater at its source on the project site

King County's new stormwater code and the 2005 Surface Water Design Manual, provide a number of tools that make it easier to use the LID approach. King County encourages sustainable development practices to help balance growth with protection of our region's valuable resources.

The 2005 Surface Water Design Manual Web site includes the manual as well as supporting documents, drawings, and references.
