S. 1730, a bill to direct the Administrator of the National Oceanic and Atmospheric Administration to make grants to State and local governments and nongovernmental organizations for purposes of carrying out climate-resilient living shoreline projects tha

S. 1730 would amend the National Sea Grant College Act and the Coastal Zone Management Act of 1972 to authorize the appropriation of $50 million annually over the 2021-2024 period for the National Oceanic and Atmospheric Administration to provide grants to states and university partners to research, design, and implement projects that restore or stabilize shorelines using nature-based approaches.

Using historical spending patterns for similar grant programs, CBO estimates that implementing S. 1730 would cost $174 million over the 2021-2025 period and $26 million after 2025, assuming appropriation of the authorized amounts.

The costs of the legislation, detailed in Table 1, fall within budget function 300 (natural resources and environment).
