Title
Resolution in Support of City's Revised Public Street Stormwater Management Guidelines Policy
Memorandum
On February 18, 2014, City Council passed Resolution R-14-051 adopting a Green Streets Statement consisting of Stormwater Guidelines for Public Street construction and reconstruction. The resolution and policy were the result of work by the Environmental Commission Water Committee with assistance from City Staff (Systems Planning, Engineering, and Public Works units of Public Services).
During the drafting of the original policy the Water Committee and City Staff concluded that the most common denominator in green infrastructure is infiltration of stormwater on-site where it is generated. As such, a policy statement regarding stormwater management guidelines for public street construction and reconstruction was developed to set infiltration standards based on the ability of the project site to infiltrate stormwater.
In 2023, the Systems Planning Unit Water Group was requested by the Environmental Commission to provide data regarding some of the Green Streets projects that the City has successfully completed. That data was provided in a September 29, 2023 memo titled "Green Streets Policy - Implementation Update".
As a result, City Staff have reviewed and are proposing revisions to the Green Streets Policy based on almost 10 years of implementation experience. Over the past several years, City Staff have encountered challenges to applying the Policy successfully. A change in preventative road maintenance changed the way that the City maintains and rebuilds roads. Because of this change in practice, there were fewer opportunities to implement the Policy. Thus, City Staff have been working to determine a more effective method to work with road projects to increase infiltration.
City Staff now recommend revisions to the Green Streets Policy. Here is a summary of the proposed revisions:
