Three levels of government maintain roads in Pinellas County, and sending a pothole report to the wrong one wastes weeks.
State roads: FDOT District 7. The Florida Department of Transportation maintains the State Highway System, which in Pinellas includes the county's biggest corridors: US 19, US 92, Gulf-to-Bay Boulevard (SR 60), the Courtney Campbell Causeway, plus other numbered state routes and interstate facilities (I-275). FDOT handles their pavement, signals it owns, and drainage inside its rights-of-way. Signs are also prohibited on state road rights-of-way by statute. Report state-road issues to FDOT District 7 (Tampa).
County roads: Pinellas County Public Works. The county's Transportation Division manages bridge, roadway, and traffic maintenance on the county road network, along with the countywide traffic signal system (Advanced Traffic Management Systems). County-maintained roads exist both in unincorporated areas and, for certain major corridors, inside city limits. The county publishes a Road Jurisdiction Viewer map specifically so residents can identify who maintains a given segment; use it before reporting.
City streets. Inside St. Petersburg, Clearwater, Largo, and the other municipalities, local neighborhood streets are generally maintained by the city's public works department. Cities also handle their own sidewalks, local signage, and street lighting arrangements.
How to report a problem. For county roads: SeeClickFix, the Pinellas County app, pinellas.gov's Report a Problem service, or 727-464-3000 (weekdays 8 to 5). For city streets: the city's own reporting channel (St. Petersburg and Clearwater both run online systems). For state roads: FDOT District 7. If you are unsure, start with the county's Road Jurisdiction Viewer or just report to the county, which can redirect.
Common confusions. Gulf Boulevard through the beach communities has segments with different maintaining agencies, so check the map rather than assuming. Private streets in gated communities and mobile home parks are maintained by their owners or associations, not government. Sidewalk responsibility often differs from road responsibility. Streetlights are frequently owned by Duke Energy even on public roads; outages usually go to the utility with the pole number.
Drainage within a road right-of-way belongs to whoever maintains that road, which is why flooding reports also follow the road jurisdiction.
