Looking for “Shovel Ready” projects
Ineligible Activities	Funding for buildings used for the general conduct of government Enlargement of dam or levee beyond original design Emergency response services; however, funds may be used to enhance the resilience of facilities Forced mortgage payoff Assistance to private utilities Maintenance projects Operations
Benefit Cost Analysis (BCA)	When comparing and selecting Infrastructure and Buyout projects, SCOR will complete a Benefit Cost Analysis to determine the dollar value for the positive impact the project will have on the area. For example, if the cost to restore a wetland is $50,000 and will prevent $100,000 in future flood damage, the BCA is 2 (benefit divided by cost).
