Approved Regulations Allowed Activities Benefits Floodplain Map Amendment Regulation Change Process Watch - Virtual Meeting
New floodplain regulations were approved in 2021. These changes limit development in the floodplain. Making this change will keep flooding from getting worse in areas near streams and creeks. Also, it's important to have green space near creeks so that water can flow without impacting buildings on a property and putting people at risk when it rains.
New regulations were initially scheduled to go into effect in April 2022. However, that date has been pushed back to July 19, 2022, after federal floodplain maps are updated.

Effective July 19, 2022
Extend building restrictions for new development to the entire floodplain.
- You would no longer be able to build new structures in the floodplain.
- New roads would also need to provide dry access during a major rainstorm.
- These changes would impact vacant lots in the floodplain.
- Properties in the floodplain already developed
- Properties 0.5 acres or less
We chose the July 19, 2022, effective date so that it coincides with the release of the new federal floodplain maps. If your property is no longer in the floodplain, according to the maps, you will not be required to follow these regulations.
You can still do these activities in the floodplain (under current and new regulations). What you can do is based on the size and location of your property. You also are able to build on areas of your property that are not in the floodplain.

- Reduce the severity of flooding. Flooding is not as bad when water has more room to flow and soak into the ground.
- Benefit the quality of streams and rivers;
- Protect wildlife habitat;
- Reduce risk to people and chances of property damage;
- Reduce instances of emergency rescue since fewer people will be in harm's way; and,
- Lower flood insurance premiums for people living in Raleigh.
Floodplain Map Amendment
On January 19, 2022, the Federal Emergency Management Agency (FEMA) issued a “Letter of Final Determination” for the revised preliminary flood maps that have been in process for many years. As part of this letter, the City will have until July 19, 2022, to officially adopt these preliminary maps as the effective FEMA flood maps for Raleigh. After the July effective date, these maps will be used for all permitting in the FEMA floodplain and for all flood insurance rate setting in the City.
With the new mapping, all the FEMA floodplain area in Raleigh will be based on future conditions. Future conditions are based on the existing zoning in the watershed not the current development in the watershed. Overall, the number of buildings in the floodplain will decrease with this new, more accurate mapping. This is mainly due to a correction in the Crabtree Creek model that more accurately reflects conditions in the watershed.
Regulation Change Process
- Input from community stakeholder group and the public. We collected survey responses in late December 2020 to early January 2021. See results.
- Recommendations shared with the Planning Commission and its text change committee.
- Recommendations approved by Stormwater Management Advisory Commission & Raleigh City Council.
- Official ordinance change process, including a public hearing that was on May 4 and input (if approved by Council).
Watch - Virtual Meeting
We held a virtual meeting on Dec 8, 2020. Staff presented on ways you can stay safe in the floodplain. We also shared what we're doing to protect communities in the floodplain with proposed regulation changes.
