1. Short title This Act may be cited as the Rim of the Valley Corridor Preservation Act . 2. Findings Congress finds as follows: (1) The Santa Monica Mountains National Recreation Area was authorized as a unit of the National Park System on November 10, 1978. (2) The Santa Monica Mountains and the Rim of the Valley Corridor include— (A) nationally significant resources— (i) outstanding examples of geologic history, including the evolution of the Transverse Ranges Province; (ii) a diversity of well-preserved marine and terrestrial paleontological resources; and (iii) high biodiversity, including outstanding examples of native grasslands, coastal sage scrub, chaparral, dry coniferous forests, and alluvial fan sage scrub; and (B) nationally significant cultural resources that represent a wide range of themes related to human use and settlement in the region— (i) high concentrations of archeological resources that provide insight into more than 10,000 years of Native American history; and (ii) landmarks that represent topics such as architecture, recreation, and space exploration. (3) Expanding the Santa Monica Mountains National Recreation Area would provide new opportunities for the National Park Service to serve a broad range of urban communities, including many that are underrepresented in national parks and underserved by State and local parks. 3.
