Design for the Future: Storm Water Management Manual Update
Since the last update of the City of Memphis’ Drainage Manual in 1990, development boomed in Shelby County, directing attention to chronic flooding and other storm water management issues. To assist Memphis and Shelby County in looking to the future, EnSafe developed a comprehensive, state-of-the-art Storm Water Management Manual that will ensure consistency in designs, practices, and regulation county-wide.
Revising and updating the drainage manual were primary tasks. An important feature of the manual is the addition of storm water volume control, an effective means of preventing downstream flooding from increased runoff volume resulting from basin development.
EnSafe developed a three-volume manual comprising Policy, Drainage, and Best Management Practices manuals; compiled and updated polices; established new policies; incorporated new technologies; provided updated resource data; and improved functionality.
EnSafe created a web portal, www.stormwatermatters.com, where an electronic version of the manual is available. The manual is user-friendly with links to equations, figures, and examples.
