Flanked by the wide Indian River Lagoon on the east and the St. Lucie River on the west, the Town of Sewall's Point is a three-mile residential peninsula directly opposite the St. Lucie Inlet. Because water surrounds the town on three sides, properties from North Sewall's Point down to South Sewall's Point face open-water wind fetch and salt air from both rivers. All window and door permits are reviewed by the Town of Sewall's Point Building Department at 1 South Sewall's Point Road.
With the Indian River Lagoon to the east and the St. Lucie River to the west, homes from High Point to South Sewall's Point take open-water gusts from both directions.
We serve Martin County homes from our Fort Lauderdale office.

During the September 2004 landfalls of Hurricanes Frances and Jeanne, Sewall's Point took direct east-southeast eyewall winds across the Indian River Lagoon through the St. Lucie Inlet, followed by backside westerly gales across the St. Lucie River. Under the 8th Edition Florida Building Code (ASCE 7-22), the entire peninsula sits on the 162 mph Risk Category II wind contour.
Because riverfront and ridge-top homes along North and South Sewall's Point Road have unobstructed water exposure, window and door openings require high positive and negative design pressures (DP), 316 stainless steel coastal hardware, and Low-E laminated glass.
Custom riverfront estates in South Sewall's Point, Archibalds Landing, and High Point feature expansive fixed picture windows, casements, and multi-panel sliding or out-swing French doors oriented toward the Indian River Lagoon or the St. Lucie River, while elevated ranch and two-story homes along the central ridge often pair colonial or coastal-contemporary frames with insulated Low-E impact glass.
Our hinged impact doors (French and entry doors) swing out. Sliding glass doors and garage doors don't swing.

The fine print
Martin County is outside the HVHZ. Its Risk Category II wind map runs from 150 to 165 mph, above the 140 mph mark that puts the entire county in the wind-borne debris region.
