This bill mandates the Secretary of the Interior to conduct a special resource study of Lower Presidio Historic Park in Monterey, California. The primary goal of this study is to assess the park's national significance and its potential for inclusion within the National Park System, recognizing its extensive history from indigenous cultures to its role in establishing American sovereignty. The study requires the Secretary to evaluate the suitability and feasibility of designating the area as a unit of the National Park System. It also necessitates considering various alternatives for the park's preservation, protection, and interpretation by federal, state, local, tribal, or private organizations. Furthermore, the Secretary must consult with interested stakeholders and identify cost estimates for any federal acquisition, development, operation, and maintenance associated with these alternatives. A report detailing the study's results and recommendations must be submitted to Congress within three years of funding availability.
