Abstract

Historic African American communities in Prince George's County, Maryland

Purpose

The coverage was developed using a 1:2400 property base, the county boundary and major roads as a reference. The primary sources of information used were boundary maps of the historic communities located in the historic preservation files and references to the stream layer when applicable. The attributes include the PG-ID, the community name and community classification. Additional information is documented in the Historic Sites and Districts Plan published by Prince George's County Planning Department.
