What It Does: S. 1870 redraws the park’s boundary to include the "Rim of the Valley Unit" shown on an official NPS map; any lands the federal government acquires there would be managed as part of the existing recreation area. The bill keeps utility and water‑facility operations in place and emphasizes minimizing impacts to park resources. Sponsors say the addition covers a bit over 118,000 acres and follows a 2016 National Park Service study recommending expansion.

Who’s For It:

• Concerns about effects on utilities and water facilities have been raised over the years; the bill and recent committee report language clarify that operations, maintenance, or modifications can continue, with reasonable steps to avoid impacts on park resources.
