H.R. 2427 would authorize the appropriation of $3 million annually for the National Park Service’s (NPS’s) Chesapeake Bay Gateways and Watertrails Network grant program from 2020 through 2025. Under current law, that authorization expires at the end of 2019. In 2018 and 2019, the NPS allocated about $2 million each year for the program. Assuming appropriation of the authorized amounts, CBO estimates that implementing H.R. 2427 would cost $13 million over the 2019-2024 period and $5 million after 2024.
The costs of the legislation (detailed in Table 1) fall within budget function 300 (natural resources and environment).
