Full Breakdown
North Port's Unified Land Development Code groups seawalls, bulkheads, and retaining walls together under its Marine Improvements article. Riprap facing must be stacked at a minimum 2:1 horizontal-to-vertical slope up to mean high water or four feet above the channel bottom, whichever is less, and a finished seawall's cap must sit at least four feet above mean low water. New or replacement seawalls are barred outright along the designated Class I portion of the Myakkahatchee Creek and its bypass canal. Any dock or seawall project first needs a Certificate of Zoning Compliance and building permit, and the design plans must carry a Florida-licensed engineer's seal.
Violations & Fines
Building a canal seawall, bulkhead, or retaining wall without the required permit and engineer-sealed plans is a Unified Land Development Code violation; the City can refer it to Code Enforcement, revoke development rights, or seek injunctive relief and attorney's fees.
