What matters for project planning
Durham maintains official floodplain guidance and separate procedures for historic district, landmark, and sign designations. Parcel-level flood status and local historic designation should be checked before structural, exterior, or drainage work is scoped.
Official sources
Verify the property, not just the city
Citywide context cannot establish a parcel’s flood zone, historic designation, stream buffer, permit requirements, soil conditions, or concealed construction. Verify parcel-specific flood zone, historic designation, and permit requirements directly with the Durham County authority before any work is authorized.
