Seawall Repair in Madeira Beach

Getting to know Madeira Beach

Madeira Beach is named after the Portuguese island of Madeira. John's Pass, at its south end, was cut by an 1848 hurricane and named after homesteader John (Juan) Levique. The town incorporated in 1947 and became a city in 1951 after annexing South Madeira. The 2020 census counted about 3,900 residents.

A 1926 causeway brought the first houses, and dredging in the 1950s and 1960s added land on the bay side. The Tom Stuart Causeway is the city's single bridge to the mainland, and John's Pass is one of the area's busiest waterfront districts.

The shoreline in Madeira Beach

Much of the bayside residential land was created by dredging in the 1950s and 1960s, so walls on those canals hold back dredged fill. Condos and hotels along the beach date mostly from the 1970s and 1980s.

A quick Madeira Beach checklist

• Ask whether your canal lot is on dredged fill and how that affects the design
• Confirm the city building permit and County seawall permit are both in the contractor's scope
• Write down when you first noticed the problem and whether it changed after high tides
• Note any dock, lift or pool within ten feet of the wall
