Upper Marlboro Maryland is the county seat of Prince George's County — the Maryland county directly adjacent to Washington DC with the highest concentration of federal government employees outside the capital. Joint Base Andrews (Air Force One's home) is in Prince George's County. The community is vulnerable to flooding from the Patuxent River watershed. The county's proximity to DC makes it a secondary consideration in any major attack on capital infrastructure.
