Low Impact Development

Stormwater Management Requirements are Changing!

Proposed Redmond Low Impact Development
  Zoning Code Changes

Proposed changes to the Redmond Zoning Code
5% Small Storm Infiltration Set Aside

  • Redmond is required to amend City code to eliminate barriers that would prevent the use of Low Impact Development.
  • The webinar reviewed proposed changes to Redmond’s Zoning Code to meet state and federal requirements.
  • Redmond must comply within certain parameters to meet these LID requirements. The City is open to innovative ideas as to how to meet these mandates, and will consider suggestions to the degree possible.

For more information about the Zoning Code changes, please email LID@redmond.gov, or contact Peter Holte at 425-556-2822. 


The City's stormwater management requirements are changing. These requirements will improve the health of our streams by adopting low impact development (LID) principles. 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."  To fulfill that strategy, in 2016, City staff will be revising the Redmond Municipal Code, the Redmond Zoning Code, and the Stormwater Technical Notebook.

As is required by the City’s NPDES stormwater permit, new standards will be adopted and apply to any project that is not vested before January 1, 2017.

Watch this page for updates about our process of revising code requirements and to learn more about LID in and around Redmond. Your participation in this process is welcomed.
