The damage from Hurricane Marie has left San Clemente's coastline vulnerable to further erosion and infrastructure risks. Homes in nearby communities, such as Capistrano Shores, face threats from high tides and record-breaking waves. Six oceanfront homes in Laguna Beach have already been yellow-tagged, and additional properties in Dana Point have been red-tagged due to structural instability. The declaration aims to mitigate risks to public and private infrastructure, including restrooms, seawalls, and train tracks, while preparing for potential impacts from the looming Super El Niño weather pattern.
