The District’s Current Flood Hazard Rules
Current Flood Hazard Rules
Building Permits are required for new construction or development in the Special Flood Hazard Areas (SFHA). All development projects in SFHA must comply with the Title 12 DCMR - DC Construction Codes (Managed by DCRA) and Title 20 DCMR Chapter 31 - Flood Hazard Rules (Manage by DOEE).
Proposed Revisions to the Flood Hazard Rules
DOEE is considering revisions to our existing Flood Hazard Rules to ensure that the District's buildings and residents are more resilient to floods in the face of a changing climate that will increase the city's flood risk. DOEE began this process in March 2020 and you can find updates on the status and latest findings of the regulations below. We aim to begin the formal rulemaking process in mid-to-late 2021.
Upcoming Outreach for the Proposed Flood Hazard Rules
Residential Public Input Webinars – Summer 2021
DOEE hosted online presentations regarding the proposed updated Flood Hazard Rules at 5:30 pm on July 29th and at 6:30 pm on August 3rd for homeowners and renters residing in the floodplain.
Commercial/Institutional Public Input Webinars – Summer 2021
DOEE hosted an online presentation regarding proposed updated Flood Hazard Rules at 2:30 pm on August 19th for owners of commercial or nonprofit institutional properties in the floodplain.
Past Outreach on the Proposed Flood Hazard Rules
Initial Stakeholder Outreach - March 2020
In March and April of 2020, DOEE hosted a number of meetings with Stakeholders to share our proposal and gather feedback.
After further analysis, and consideration of stakeholder comments, DOEE launched a series of Technical Workshops to gather further input from technical professionals. See below for materials from these events.
Workshop 1 - Overview - April 20, 2021
- This meeting provided an overview of the draft floodplain regulations, DOEE’s outreach conducted to date, and a preview of the subsequent workshops.
Workshop 2 - Mapping - April 29, 2021
- This meeting will focus on map-related topics such as the delineation of the Tidal Shoreline Buffer (TSB), design flood elevations required in the TSB, and a discussion of the TSB’s underlying sea level rise projections. This meeting will also address DOEE’s proposal for how we will handle instances where applicants may have site-specific information that could remove their project from a regulatory floodplain.

This document describes the process that New Jersey used to establish sea level rise projections for the state.
- Supplement - Flood Risk Management Planning Resources for the District
