Know your waterfront
Port St. Lucie seawalls
are not all the same.
Tidal canals off the North Fork
The city counts 45,625 feet of tidal “ocean access waterways” with 743 single-family lots, from Sagamore and Elkcam to Kingsway and River Vista. NOAA’s North Fork station shows only about a foot of tide. City waterway inventory · NOAA North Fork datums
Freshwater canals and lakes
About 200 miles of city drainage canals, the C-23, the C-25 and the upper C-24 are freshwater and structure-controlled; the lower C-24 is tidal. Community lakes are often maintained by an association or district, as in Riverland, Sundance and Wylder; check your plat. City drainage system · Association stormwater agreements
River, lagoon and ocean frontage
The North Fork, the Indian River Lagoon and Hutchinson Island bring aquatic preserves, riprap preferences for vertical walls and beachfront CCCL permits into the decision. North Fork aquatic preserve · Florida seawall policy
Restoring a seawall within 18 inches of its old face can qualify for a state environmental exemption when the conditions are met. Local, coastal-construction and state-land requirements remain separate. In Port St. Lucie, the published residential seawall permit fee is $100 for the first 100 feet, then $5 for each additional foot, plus state surcharges. Check the full permit route and current fees.

Before choosing a proposal
Practical questions.
Better conversations.
What should I include in a project request?
Start with your community and the changes you’ve noticed at your seawall. Add a callback number and any details about cracks, movement, soil loss or earlier repairs. You can add more information as your project takes shape.
Do I need a permit to repair my seawall in Port St. Lucie?
Usually yes. The city has a separate seawall permit type. Its published residential fee is $100 for the first 100 feet, then $5 for each additional foot, plus state surcharges; confirm the current fee before applying. A state environmental exemption does not settle every local, coastal or state-land requirement. See the permit guide.
How much does seawall repair cost?
One Port St. Lucie repair contractor publishes $1,500 for minor foam or patch work up to $9,000 for moderate reinforcement or cap replacement, and a South Florida contractor serving Martin County lists roughly $500–$1,200 per foot for full replacement. Public river projects cost far more. See the cost guide.
Does insurance cover my seawall?
Federal flood insurance lists seawalls and bulkheads as property not insured, and homeowners policies often exclude water damage to them. Read the insurance guide and ask your agent for a written answer.
Who maintains the canal behind my house?
In Port St. Lucie, the city maintains most tidal ocean access waterways for stormwater, SFWMD maintains the C-23, C-24 and C-25, and the county maintains a few. Your seawall and dock are your responsibility. See the bulkhead guide.
What if my lake bank is eroding?
In planned communities such as Tradition or St. Lucie West, the lake and its bank are often a community tract managed by an association or district; check your plat. Start with the lake bank guide.
