On February 6, 2008, the California Coastal Commission voted 8-2 to reject the planned extension through San Onofre State Beach. The TCA appealed the Coastal Commission's decision to the U.S. Secretary of Commerce. On December 18, 2008, the Department of Commerce announced that it would uphold the California Coastal Commission's ruling that found the TCA's proposed extension inconsistent with the California Coastal Act. In a release issued by the Department of Commerce, the DOC noted that at least one reasonable alternative to the project existed, and that the project was not necessary in the interest of national security. In November 2016, the TCA reached a legal settlement ending the 15-year dispute with the more than a dozen environmental organizations and the State of California. The settlement guaranteed that any roadway would avoid the Donna O'Neill Land Conservatory, the San Onofre State Beach Park, and other environmentally sensitive areas. The environmental organizations have agreed not to sue the TCA over other potential alignments that connect the 241 Toll Road to the I-5 freeway as long as the alignments do not enter the "environmental avoidance area." Los Patrones Parkway Rancho Mission Viejo, which has publicly condemned all the proposed alignments of the SR 241 extensions, helped to fund the construction of a four-lane toll-free freeway known as Los Patrones Parkway. The road, maintained by Orange County, follows the exact alignment as the proposed Tesoro Extension of SR 241 between Oso Parkway and Cow Camp Road. Rancho Mission Viejo provided $85 million of the total estimated cost of $100 million to construct the road. Los Patrones Parkway also includes a new multi-purpose pathway on the west side of the highway between Oso Parkway and Chiquita Canyon Drive, two wildlife crossings under the road, wildlife fencing, and replanting of over 100 acres of vegetation. However, local environmental groups expressed concerns that the TCA may acquire Los Patrones Parkway in the future to extend SR 241 southward. On August 10, 2018, the Orange County Public Works began construction on a $30 million project to turn a section of Oso Parkway into a bridge to allow a direct connection between SR 241 and Los Patrones Parkway. The new interchange was completed in mid-January 2021. Los Patrones Parkway was built in two phases. Phase 1 of the road between Oso Parkway and Chiquita Canyon Drive opened on September 12, 2018. However, due to significant rainfall, the opening
