Proclamation 9563
Boundary Enlargement of the California Coastal National Monument
President Obama used the Antiquities Act to expand the California Coastal National Monument by approximately 6,230 acres, adding six new units (Trinidad Head, Waluplh-Lighthouse Ranch, Lost Coast Headlands, Cotoni-Coast Dairies, Piedras Blancas, and Orange County Rocks and Islands). The proclamation withdraws these federal lands from development, mining, and mineral leasing, and directs the Secretary of the Interior to manage the expansion through the Bureau of Land Management.
