Based on information from the National Park Service, CBO expects that existing efforts to protect structures in the camp from flooding would fulfill the requirements in the bill. On that basis, CBO expects that implementing S. 673 would have insignificant costs over the 2025-2030 period. Any related spending would be subject to the availability of appropriated funds.
