Where to Check Your Property
The NC Floodplain Mapping Program status map shows each county's stage: discovery, engineering analysis, floodplain mapping, preliminary and effective
NC Emergency Management's Flood Risk Information System (FRIS) shows flood hazard data for individual properties
In Mecklenburg County, the 3D Floodzone Maps tool shows property flood risk
Project: Flood Zone Duplex, Charlotte, NC
New duplex on a FEMA flood zone lot in Charlotte, Mecklenburg County
An existing flood permit required the driveway and building pad about four feet above existing grade
Permitting through Mecklenburg County
Challenges
Three frameworks applied at once: FEMA flood zone rules, the existing flood permit and Charlotte's stormwater ordinance
Four feet of fill created a step-up that had to drain away from the building
Runoff could not create adverse drainage impacts on neighboring lots
Objectives
Meet the flood permit's elevation conditions.
Drain the raised pad and driveway safely.
Satisfy Charlotte and Mecklenburg County drainage criteria in one design.
Solutions JRH Engineering Provided
Civil engineering grading design with four-foot fill for the driveway and building pad
A drainage plan directing stormwater to compliant outfall conditions
Grading and drainage documents prepared for Mecklenburg County review
Results:
Flood permit elevation conditions satisfied
Stormwater managed across the fill area without adverse impacts to adjacent properties
FEMA, flood permit and Charlotte stormwater requirements addressed in a single design
Planning Ahead of a Remap
Check both the effective map and any preliminary map before buying or designing
Budget for fill, higher finished floors and drainage on lots near mapped floodplains
Improvements to existing buildings in a Special Flood Hazard Area can trigger the 50% substantial improvement rule
