What matters for project planning
Jacksonville provides floodplain resources and a municipal history that documents the city’s military-driven growth. Coastal-plain drainage, current flood maps, and the access rules for military property should be verified before work begins.
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.
