The Action Plan Amendment 4 is a substantial amendment that incorporates $277,853,230 in additional CDBG-DR funds allocated to Puerto Rico through the Federal Register Vol. 85, No. 17 issued on January 27, 2020 (85 FR 4681), for unmet infrastructure need. Budgetary changes are made in this substantial amendment to incorporate funds for infrastructure into the Non-Federal Match Program (previously the FEMA Coordination Program), and increase funds in the Home Repair, Reconstruction, or Relocation Program (R3) by the same amount. Programmatic changes include the clarification of eligibility criteria for several programs. This substantial amendment also eliminates the Mortgage Catch Up Program, due to HUD limitations on funding for this activity; eliminates the Economic Recovery Planning Program, as activities for this program are encompassed in other economic recovery and planning efforts; and consolidates the Strategic Projects and Commercial Redevelopment Program under the Economic Development Investment Portfolio for Growth Program.
