Laguna Beach officials said Wednesday that a graffitied Thousand Steps Beach sea cave is located on private property and are working with the property owners to remove the paint. Photos of the usually whimsical beachscape were posted to social media platforms, earning outrage from many Laguna Beach residents exasperated by a segment of visitors who vandalize natural spaces. “We are working with the property owners on cleaning up the graffiti and expect to have the situation resolved soon,” Laguna Beach Community Development Director Marc Wiener wrote in an email.
