RE: https://sfba.social/@jeridansky/117299406449410531 Wow. "Away in Hawaii for a wedding, doctor Shalesh Gupta checked video footage from his Beach Road home and realized that his patio collapsed into the ocean. The waves had destroyed his seawall. The bedroom and living room fell next." And that video loop in the article is mesmerizing. I read a wonderful book "The World in a Grain" that's all about sand. There's a part discussing beach erosion and why beach "nourishment" (dredging / adding sand) is a bad idea. But it sounds like the seawall they want to build is not a good idea either.
