Stuart and County Government
Stuart is the county seat and contains the courthouse, principal county offices, healthcare, a historic downtown, marinas, and regional businesses. It occupies a waterfront setting where branches of the St. Lucie River meet the estuary.
Downtown and the riverfront support boating, fishing, arts, and visitor activity. Individual channels and marinas require detailed local or nautical maps.
Palm City and Jensen Beach
Palm City is a large suburban community west of the St. Lucie River with housing, schools, golf, and commercial services. Jensen Beach is associated with the Indian River Lagoon and access to Hutchinson Island beaches.
Development and roads can change, so current county GIS information is needed for detailed travel and land questions.
Jupiter Island and the Southern Coast
Jupiter Island is a barrier island bordered by the Atlantic Ocean and Intracoastal Waterway, extending between the Jupiter Inlet and St. Lucie Inlet region.
Hobe Sound and Jonathan Dickinson State Park contain coastal scrub, dunes, river, and wetland habitats. Beach and park conditions should be checked before travel.
Indiantown and the Western County
Indiantown is an incorporated village in western Martin County where agriculture, ranching, logistics, and activity along the St. Lucie Canal are important.
Canal operations, farms, and private-property boundaries require current official records.
St. Lucie River and Conservation
The St. Lucie River and Indian River Lagoon are central to boating, fishing, estuarine ecology, and water-quality management. Official tourism information highlights extensive parks and conservation land across the county.
Water quality, tides, levels, and wildlife rules can change, so current charts and agency guidance are required for water activities.
