Community Development Block Grant Disaster Recovery Projects need to be part of a rebuilding/recovery effort Not eligible if they focus on future disasters Projects must address a serious and immediate threat to community health/welfare CDBG-DR funds can be used as the non-federal match for USACE and FEMA projects Examples of Eligible Projects: Buyouts Relocation Debris removal Property rehabilitation Constructing or rehabilitating public facilities (i.e. streets, water and sewer systems) Planning and administration costs 9
CDBG-DR and Green Infrastructure From the Federal Register, as part of the CDBG-DR Funds in Response to Hurricane Sandy: To foster the rebuilding of more resilient neighborhoods and communities, HUD strongly encourages grantees to consider sustainable rebuilding scenarios such as the use of different development patterns, infill development and its reuse, alternative neighborhood designs, and the use of green infrastructure. www.sustainablecommunities.gov 10
