The DowntownDC BID area encompasses the neighborhoods of Gallery Place, Chinatown, Federal Triangle, Franklin Square, McPherson Square, Midtown and Penn Quarter. Property owners fund this special district through tax assessments. The DowntownDC BID provides services in the areas of safety, hospitality and maintenance through our red-uniformed Safety/Hospitality and Maintenance (SAM) employees, physical improvements, homeless services, transportation, marketing, special events, planning, economic development and environmental sustainability.
