Cliffside Properties Endangered By Eroding Pacifica Coastline

On a stretch of coast between San Francisco and Half Moon Bay, rows of apartments sit on cliffs, dangerously close to falling into the Pacific Ocean. Powerful waves and heavy rains from El Niño storms have accelerated the erosion of the coastal bluffs in Pacifica, Calif., a spectacle widely shared online. On Friday, city officials there declared an emergency. On Monday, they condemned 20 apartments, placing yellow tags on doors and ordering tenants to collect their belongings and leave.
