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 can't establish a parcel's flood zone, historic designation, stream buffer, permit requirements, soil conditions, or concealed construction — confirm those directly for the Durham address in question.
