In 2006, the Olympia City Council responded to drainage and flooding concerns by declaring a moratorium on grading and subdividing in the area south and southwest of Chambers Lake. 

The Final Chambers Basin Moratorium Evaluation Report summarizes the technical and policy evaluation of the interrelated groundwater and stormwater problems in a portion of Chambers Basin, and their implications for future land use development. 

The evaluation was conducted during a moratorium on development begun in April 2006.  The draft report was completed in June 2007, and public meetings and hearings were conducted in September 2007.  The report was finalized in March 2008 and is being used as a reference document for the 2008 annual Comprehensive Plan amendment process.  Each chapter of the final report is provided below in printer-friendly PDF format:
