Low Impact Development

Stormwater Management Requirements have been Updated!

The City's stormwater management requirements have been updated in response to the City’s NPDES stormwater permit requirements. These requirements will improve the health of our streams by adopting low impact development (LID) principles.

Numerous policies in Redmond's Comprehensive Plan support the use of LID, and Redmond's Water Resources Strategic Plan, adopted in 2015, calls for the City to develop a "Low Impact Development (LID) approach...to support desired stormwater management strategies and as a required element of our NPDES permit." In 2016, City staff developed revisions to the Redmond Municipal Code, the Redmond Zoning Code, and the Stormwater Technical Notebook, and these have all been approved with an effective date of January 1, 2017.

Additional Study in Urban Centers

The City is working to study further the competing needs that exist within the City's two urban centers (Downtown and Overlake) that may result in modifications to how low impact development is implemented in those areas.
