The City of Marco Island's seawall permit asks for more than a sketch (City of Marco Island seawall application):
That survey requirement is about your neighbors. Canal walls on Marco run lot to lot, so the city wants to see exactly how yours lines up with the walls on either side. We design those tie-ins before anything is ordered.
| Material | Typical lifespan* | Best for | Watch-outs |
|---|---|---|---|
| Vinyl (PVC) sheet pile | 40–50+ yrs | Most canal homes | Needs a solid cap and tie-backs |
| Composite (FRP) sheet pile | 50+ yrs | Long service life | Higher cost |
| Precast concrete panels | 30–50 yrs | Matching older walls | Joint seals must be good |
| Steel sheet pile | 25–40 yrs in salt water | Commercial walls | Needs corrosion protection |
| Timber | 15–25 yrs | Short-term, sheltered sites | Borers and rot in salt water |
*Lifespans depend on exposure, installation, and maintenance.
We usually recommend vinyl or composite sheet pile with a poured cap. It resists salt and can be finished to match your deck.
Often. Driving new sheet pile just waterward can leave the old wall as backing. Florida DEP treats rebuilding at the old line, upland of it, or within one foot waterward differently from new construction, which can simplify state review. On a narrow canal we keep the new face as close as practical to preserve boat room.
Full bulkhead replacement in Marco Island typically runs $250–$600 per linear foot. A 75-foot residential vinyl sheet pile replacement typically runs $20,000–$45,000. Material, height, barge access, and dock removal all affect the price. See our Florida seawall cost guide.
Replacing the dock too? See marine construction in Marco Island. We also replace bulkheads in Naples and Cape Coral.
Marco canal walls connect at property lines. The survey shows exactly how your new wall lines up with the ones beside it.
