What matters for project planning
Wilmington maintains historic-preservation and stormwater programs for a low coastal city. Local-district review, current flood mapping, wind exposure, salt, drainage, and high water tables can all change material and installation choices.
Official sources

Citywide context cannot establish a parcel’s flood zone, historic designation, stream buffer, permit requirements, soil conditions, or concealed construction. Confirm those items with the appropriate authority and selected provider before work begins.
