Get to know your waterfront
River Park is an unincorporated community of about 6,500 residents on the upper North Fork, platted as River Park Units 1 through 10. Census and USGS data show it touching both residential canals and the river itself. Despite the Port St. Lucie mailing addresses, permits come from St. Lucie County, not the city.

Aging canal walls on the upper river
River Park’s canals are an older neighborhood on the North Fork, so expect aging walls, shoaled canal ends and sediment from upstream discharges. The county’s Marine Construction Checklist covers seawalls, bulkheads, riprap, docks and dredging and requires state, federal and water-management approvals at upload.
In-water work next to the North Fork St. Lucie Aquatic Preserve needs FDEP and Army Corps authorization, and county manatee zones apply. Marine Construction Checklist (Building & Code Regulation) · North Fork, St. Lucie Aquatic Preserve · Chapter 68C-22 Manatee Protection Rules (rule list)
What could the work cost?
Ask for the county permit, state exemption paperwork and any dredging near the wall as separate line items.
Published examples are attributed context from Treasure Coast and nearby South Florida sources, not a Port St. Lucie average or a quote. Your wall needs a property-specific written scope.

A River Park checklist
Use these steps to gather records and prepare a property-specific conversation. Public records and project references do not describe the condition of your wall.
Pull the permit history
Search the address on the city or county permit portal for seawall, dock and lift permits and their final inspections before the first site visit.
Confirm the jurisdiction
Check the parcel record; River Park is unincorporated county.
Prepare the county package
Use the Marine Construction Checklist and the county’s online portal.
