Sanford and County Government
Sanford is the county seat and contains the courthouse, principal county offices, healthcare, a historic downtown, rail and highway connections, and the Lake Monroe waterfront.
Orlando Sanford International Airport also supports regional travel and tourism. Current airport and street maps are required for detailed navigation.
Lake Mary and the Western Business Corridor
Lake Mary and Longwood are major corporate, office, and residential centers near Interstate 4. Altamonte Springs and Casselberry extend the western urban corridor with shopping, healthcare, and transportation services.
Development and roads change, so current county GIS information is important for address and jurisdiction questions.
Oviedo and Winter Springs
Oviedo and Winter Springs are growing eastern residential and educational communities near the University of Central Florida and Research Park.
The Econlockhatchee River and associated wetlands place conservation land close to suburban development.
Lake Monroe and Lake Jesup
Lake Monroe is a large lake in the St. Johns River system and forms Sanford’s waterfront. Lake Jesup is a broad shallow lake and wetland ecosystem in central and eastern Seminole County.
County recreation information includes Lake Jesup Park and the Lake Monroe Trail Loop. Water levels, ramps, and trail conditions should be checked before travel.
Wekiva River and Conservation Lands
The Wekiva River Basin contains rivers, springs, wetlands, forest, trails, and wildlife habitat in western Seminole County.
County recreation guidance notes that Markham Woods Trailhead connects with off-road trails in the adjacent Wekiva River Basin State Park.
Color Map
The color version separates Seminole County from neighboring counties and helps show Sanford, the other incorporated cities, major lakes, rivers, and conservation areas.
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.
