Stormwater Management Guidebook

<< Back to Stormwater Management main page

Overview

The Stormwater Management Guidebook (SWMG) provides technical guidance on how to comply with the District’s Stormwater Management Regulations.

Download here:

• 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.

Training Sessions

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.

Please RSVP by registering online or by contacting Brandon Hunt at [email protected] or 202-688-3415 to confirm that space is available in the session you would like to attend.

Submit Stormwater Management Plan Information Online

Use the DOEE Surface and Groundwater System 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 DOEE Surface and Groundwater System. 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. Learn more about DOEE plan review fees and payment options. After receiving a complete submission, DOEE will provide review comments within 30 business days.
