Fort Pierce and County Government
Fort Pierce is the county seat and contains the courthouse, principal county offices, healthcare, a historic downtown, port facilities, and marine services near the inlet.
Fort Pierce Inlet connects the Atlantic Ocean with the Indian River Lagoon and supports port, boating, fishing, and beach activity. Current charts and weather are required for navigation.
Port St. Lucie and Growth Areas
Port St. Lucie is the county’s largest city, with extensive neighborhoods, schools, hospitals, commerce, parks, and recreation. Tradition and western development areas are major growth districts.
Development boundaries and roads change, so current county GIS information is important for address and jurisdiction questions.
Indian River Lagoon and Hutchinson Island
The Indian River Lagoon extends along eastern St. Lucie County. Hutchinson Island contains Atlantic beaches, public access points, conservation areas, and waterfront recreation.
Official tourism guidance highlights kayaking, canoeing, mangrove exploration, reefs, beaches, and wildlife viewing throughout the county’s waterways.
St. Lucie River and Paddling
The St. Lucie River and North Fork St. Lucie River are major waterways in southern St. Lucie County and the Port St. Lucie area. Calm river sections and mangrove wetlands support paddling and fishing.
Water levels, water quality, ramps, and navigation conditions can change, so current official information is required.
Inland Agriculture and Natural Land
Western St. Lucie County contains citrus and agricultural land, ranches, wetlands, and low-density communities. The landscape becomes more rural toward Okeechobee County.
Farm, wetland, and private-property boundaries require current official records.
Color Map
The color version separates St. Lucie County from neighboring counties and helps show Fort Pierce, Port St. Lucie, beaches, the lagoon, rivers, and Hutchinson Island.
Black-and-White Map
The black-and-white map retains the county outline and selected place names for grayscale printing.
Outline Map
The outline version contains boundary lines without labels or fills, allowing custom notes and place names.
