The Stormwater Management Guidebook (SWMG) provides technical guidance on how to comply with the District’s Stormwater Management Regulations.
- 2020 Stormwater Management Guidebook – clean copy
- DOEE Response to Public Comments for the 2020 SWMG
- 2020 Stormwater Management Guidebook – changes tracked from February 2019 draft
Older versions and information about updates to the SWMG may be found here.
Any project that is currently under review by DOEE or submitted by February 29, 2020 may continue to use the Best Management Practice (BMP) specifications in the 2013 Guidebook and related errata. These projects also have the alternative of using the new Guidebook’s BMP specifications.
DOEE holds free public training sessions on the requirements of the Stormwater Management Regulations and SWMG. DOEE has also made available presentations and other training-related documents.
Submit Stormwater Management Plan Information Online
Use the Stormwater Database to submit compliance calculations and supplemental information to DOEE as part of its stormwater management plan review process. DOEE will only review plans that have been submitted in the Stormwater Database. This applies to all projects, including projects which only require a walk-through plan review. Submission of a complete stormwater management plan includes payment of filing fees. After receiving a complete submission, DOEE will provide review comments within 30 business days.
