Other Assistance Considerations
Formula and Matching Requirements
Statutory formula is not applicable to this assistance listing.

Matching is mandatory. 40%. NIPA grants may be used for up to 60 percent of future eligible project costs. Other Federal assistance may satisfy the non-Federal share requirement for an NIPA grant, but total Federal assistance for a project receiving an NIPA grant may not exceed 80 percent of the future eligible project costs. Unless otherwise authorized in statute, local cost-share that exceed the 80 percent Federal-share maximum will not be considered matching funds if the source of those funds is ultimately a Federal program. Non-Federal sources include State funds originating from programs funded by State revenue, local funds originating from State or local revenue funded programs, private funds or other funding sources of non-Federal origins. Funds from the Tribal Transportation Program (23 U.S.C. 202), TIFIA, a Federal land management agency, or other Federal source that is expressly authorized in statute may be used for the non-Federal share. Unless otherwise authorized in statute, local cost-share may not be counted as non-Federal share for both the NSFHP and another Federal program. For any project, the Department cannot consider previously incurred costs or previously expended or encumbered funds towards the matching requirement. Matching funds are subject to the same Federal requirements as awarded funds. Matching requirements are voluntary.
