What matters for project planning
Jacksonville publishes floodplain mapping and a history of the city's Camp Lejeune-driven growth, both of which bear on foundation work -- coastal-plain drainage behavior, current flood-zone boundaries, and base-adjacent access rules are all worth checking before scheduling anything.
Official sources
Verify the property, not just the city
General information about Jacksonville as a whole says nothing about one specific lot's flood-zone status, historic overlay, buffer requirements, permit needs, soil makeup, or hidden construction underneath it. Those questions get answered parcel by parcel, by whichever county or city office handles them and by whichever provider ultimately takes the job.
