This is the Congressional Budget Office Cost Estimate as ordered reported by the Senate Committee on Commerce, Science, and Transportation on July 22, 2020. From the Document: "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 [Congressional Budget Office] 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."
