In the wake of the massive Snohomish County landslide ( that killed 43 people in the Steelhead Haven development near Oso, Gov. Jay Inslee and Snohomish County Executive John Lovick are set to announce a commission to make recommendations on how to avoid and respond to such slides.

The commission is expected to be announced by Inslee and Lovick at 12:45 p.m. Friday at the Snohomish County administration building, said a statement from Inslee’s office. It will be composed of about a dozen people, according to Inslee spokeswoman Jaime Smith.

Among them will be experts in geology, hydrology, planning and development and emergency management, Smith said.

The commission will conduct an independent review of the landslide and make recommendations for better planning and emergency-response efforts, according to the governor’s press statement.

The recommendations, which will be forwarded to Inslee’s office, as well as to the Snohomish County Executive, will be made by the end of the year, Smith said.

A Seattle Times investigation in June revealed that the Steelhead Haven developer never filed a required flood- plain permit, which would have helped warn of the dangers there.

And while at least one county official said after the disaster that “the slide came out of nowhere,” The Seattle Times this week documented slides ( in and around the area stretching back to1900, some as recent as 1996 and 2006.
