Marin sea-level defense costs estimated at $17B
Marin County is facing about $17 billion in expenses to protect itself from the rising sea, the second highest cost estimate in the Bay Area, according to a state planner. Dana Brechwald, a climate official at the San Francisco Bay Conservation and Development Commission, cited the cost Tuesday while briefing the Board of Supervisors on Senate Bill 272. The legislation, which Gov. Gavin Newsom signed into law in July, requires coastal counties to develop a plan to prepare for sea-level rise by Jan. 1, 2034. According to the commission, the state regulatory agency that oversees the bay, it will cost Bay Area counties $110 billion to protect themselves from the effects of about 4.9 feet of sea level rise through 2050.
