H.R. 3115 would authorize the appropriation of $50 million a year over the 2020-2025 period for the National Oceanic and Atmospheric Administration to make grants to state and local governments, nonprofit organizations, and Indian tribes to design and implement projects that restore or stabilize shorelines. Such projects would use natural materials to create buffers to lessen shoreline erosion by minimizing the impact of storms, currents, and flooding.
Using historical spending patterns for similar grant programs, CBO estimates that implementing H.R. 3115 would cost $175 million over the 2020-2024 period and $125 million after 2024, assuming the appropriation of the authorized amounts. The costs of the legislation, detailed in Table 1, fall within budget function 300 (natural resources and environment).
