Imprisoned on Treasure Island

Liz Washington dedicates her story to Treasure Island mothers suffering Child Protective Services’ human rights abuses. Liz Washington’s Tenderloin apartment door rattled. Bursting in, hands on guns, San Francisco cops grabbed her nursing infant. Liz’ daughter remembers her mom’s screams. “‘Please don’t take my baby!’” Even after moving to Treasure Island, Liz never escaped CPS’ ravenous appetite for masterminding abductions of her daughter and sons.

Did Lennar’s vibro-compaction test create sink holes on Treasure Island?

On Treasure Island May 28 and 29, 2015, the earth trembled and shook in a fenced-off location between the Island Cove Market and the Starburst Barracks. Engineers from Lennar’s vibro-compaction geotechnical subcontractor, Jafec USA, repeatedly sank four huge vibrating shafts 50 feet deep into Treasure Island fill, testing for the effect on the soil, groundwater and mud of the man-made island.
