310 ESPLANADE AVE PACIFICA, CA coastal erosion case study. MARCH,2017

"The building at 310 Esplanade Ave. was yellow-tagged and deemed uninhabitable in January 2016 after powerful surf from El-Nino fueled storms eroded the coastline and bluffs. Portions of the eroding cliff had collapsed into the ocean after rains hammered the Bay Area city." - LA Times. January 30, 2017

“Storm-driven waves have accelerated erosion of the adjacent bluffs presenting a clear danger to residents, and demolishing this structure is the only way to prevent it from crumbling to the beach below,” City Manager Lorie Tinfow said in a statement.

There were two buildings constructed in the 60's that belonged to Millard Tong, who city officials say has been aware of the bluff’s condition and filed for bankruptcy in 2015. The other building was demolished prior.

"In January, El Niño-related storms forced city officials to declare the building at 310 Esplanade Avenue unsafe and residents were asked to leave their homes. Portions of the eroding cliff had collapsed into the ocean after rains hammered the coastal Bay Area city." - LA Times. Dec 15, 2016

"In total, Pacifica spent about $3.65 million last year repairing a dozen locations that were damaged by winter storms, including the seaside cliffs. About $2 million of that is expected to be covered by the city’s insurance and about $1 million could come from a state disaster fund"

"The city helped residents relocate earlier this year. Taxpayers will be left paying for the cost of the demolition, which is about $330,000."

"Some residents fear their apartments may be next. "Because I think it is coming in. The ocean is taking back what it wants," Pacifica resident Mark Fischer said." - ABC7 January 30, 2017
