Proposed CDBG projects must be consistent with broad national priorities for CDBG: activities that benefit low- and moderate-income people, the prevention or elimination of slums or blight, or other community development activities to address an urgent threat to health or safety. CDBG funds may be used for community development activities (such as real estate acquisition, relocation, demolition, rehabilitation of housing and commercial buildings), construction of public facilities and improvements (such as water, sewer, and other utilities, street paving, and sidewalks), construction and maintenance of neighborhood centers, and the conversion of school buildings, public services, and economic development and job creation/retention activities. CDBG funds can also be used for preservation and restoration of historic properties in low-income neighborhoods.
