Stormwater Management Guidebook

<< Back to Stormwater Management main page


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

Download here:

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 Surface and Groundwater System (SGS) to submit required compliance calculations and supplemental information to DOEE for stormwater management plan review. 

DOEE will only review plans that are submitted in the SGS and have all filing fees paid. This applies to all projects, including projects that only require a walk-through plan review. After receiving a complete submission, DOEE will provide review comments within 30 business days.

Learn more about DOEE plan review fees and payment options.

Plan Review Checklists

To help design engineers better anticipate plan reviewer comments, DOEE has provided a copy of the checklists reviewers use to conduct their plan reviews. While thorough, these checklists may not include all comments a project may receive.
