Georgia Stormwater Management Manual

2016 Edition of the Georgia Stormwater Management Manual Volumes 1 & 2
The Atlanta Regional Commission worked with the state Environmental Protection Division, the state Environmental Finance Authority, a Technical Advisory Group (TAG), and a consultant team led by AECOM to update the Georgia Stormwater Management Manual (GSMM), known as the “Blue Book.”

Georgia Stormwater Shorts are a series of short, instructional videos to help you navigate the wealth of knowledge contained in the Georgia Stormwater Management Manual and supporting documents. Our first video provides an overview and introduction to the Site Development Review Tool. Future videos will cover other aspects of the manual including an overview of GSMM best management practices. Visit our Georgia Stormwater Shorts page to view our videos.
Additional Information on the GSMM 2016 Edition
- The Blue Book is not available in print but is formatted to allow for printing by the individual user. The manual is easily searchable in electronic format.
- As of January 2, 2017, MS4 permittees are required to use the 2016 Edition (February 2016) as the “latest edition,” or an equivalent manual, unless located in the 24-county Coastal Nonpoint Source Management Area or Area of Special Interest.
- Coastal communities will continue to use the First Edition (April 2009) of the Coastal Stormwater Supplement.
- Required performance standards are enumerated in the MS4 permit. Standards listed in the 2016 Edition of the Blue Book are recommended, but not required for adoption at this time. Local jurisdictions are welcome to adopt these performance standards as desired. All MS4 communities should consult the latest versions of their permit.
