Abstract: Denotes the general position of Public Housing Developments by providing the location of the building with the largest number of units in a Development’s community. HUD furnishes technical and professional assistance in planning, developing and managing these developments. Public Housing Developments are depicted as a distinct address chosen to represent the general location of an entire Public Housing Development, which may be comprised of several buildings scattered across a community. The building with the largest number of units is selected to represent the location of the development.
