Lidar technology can quantify coastal erosion in southern California. Ocean Beach, a heavily populated coastal town, can lose key infrastructure, such as houses and hotels. The cliffs of Point Loma pose no threat to infrastructure but can see a significant amount of erosion. From 1997 to 2016, both areas experienced at least 10 meters of erosion. Ocean Beach experienced lesser erosion, however a hotel and home had to be relocated. Point Loma experienced greater levels of erosion, specifically in small coves. These erosion rates are very similar to those along the west coast, specifically the California coast.
