Property Description
Waterfront Lot in Desirable Causeway Isles. Located within FEMA's LiMWA line (Limit of Moderate Wave Action), development costs can be reduced. Partner with Neo Homes to design and build your dream home on this ideally located and fully cleared waterfront lot in the highly sought-after Causeway Isles neighborhood. Positioned at the start of a point, the property offers expansive open-water views, deep water access, and protected harborage with desirable northeast exposure. A brand-new seawall was completed in April 2025, featuring a 28-inch-wide cap raised to the maximum height allowed for enhanced durability and elevation. The lot boasts 103 feet of water frontage, offering an ideal canvas for your custom waterfront residence. Causeway Isles and neighboring Yacht Club Estates are among the most coveted communities in the area, prized for their unbeatable central location. Enjoy quick access to the Intracoastal Waterway, just minutes from your dock, with the Gulf beaches only 2 miles away and downtown St. Petersburg a mere 5-mile drive. A current survey and soil testing report are available and will be provided at the appropriate point during the sales process. Don't miss this rare opportunity to own a deep-water lot in one of the Bay Area's finest waterfront neighborhoods-where lifestyle, location, and limitless potential meet. Third Avenue South is arguably the nicest street in Causeway Isles and there are currently five (5) lots that will soon be developed, and two (2) lots where new construction will soon be complete and ready for families to move into the neighborhood. Be a part of the revitalization of this unique neighborhood!! Visit the website of the builder at NeoHomes.net for details about this exceptional design-build team!!
