About the town
The Maryland Manual lists Upper Marlboro as the county seat of Prince George's County, incorporated in 1870. Its town hall is at 14211 School Lane, Upper Marlboro, MD 20772, phone (301) 627-6905.
Streets inside the town limits may belong to the town rather than the county. Prince George's County's drainage page says that if you think a road is maintained by a municipality, contact that municipality first.
Utilities and drainage
WSSC Water serves Prince George's County, and its report-a-problem page lists how to report an emergency. Not every address in a county this large is a WSSC customer, so check the name on your bill. For drainage on private property, see the county's drainage page.
