Casa Mira Homeowners Association v. California Coastal Commission

A homeowners association and its members challenged the California Coastal Commission's approval and certification of the City of Half Moon Bay's amendment to its Local Coastal Program/Plan (LCP), which prohibited long-term shoreline protective devices. The petitioners asserted that the approval and certification violated the California Coastal Act and exceeded the Commission's authority, and that the actions constituted a taking without just compensation in violation of the U.S. and California Constitutions. The petitioners alleged that their homes faced a threat of bluff collapse and erosion and that the LCP amendment would limit them "to three long-term options to address bluff erosion and sea level rise – retrofitting, removal or relocation." The petitioners contended that these limits were inconsistent with rights bestowed on property owners by the Coastal Act.
