For the first time in more than a decade, Washington state is closing a prison. The Larch Corrections Center in Yacolt, Clark County will shut its gates for the last time next week. The state’s Department of Corrections says the population of the 240-bed minimum security prison is now down to about 60 people, all of whom will be relocated by Monday, Oct. 2.

The reason for the closure is a matter of falling demand — there are simply fewer people behind bars in the state. The department says these trends will likely accelerate in the coming years, potentially leading to more prison closures.

“We’ve had serious decarceration in this country now for the last 15 years, not in every state, but in most states and the federal government,” said Mary Stohr, a former corrections employee at Larch and current professor of criminal justice and criminology at Washington State University.

Stohr said there are a myriad of reasons behind the closures — prisons are expensive, violent crime is down per capita, legalization and decriminalization of drugs have led to fewer arrests for nonviolent offenses, and a decrease in the percentage of young people may also be behind the dip.

In the short term, Stohr acknowledges there will be pain points as prisons close.

“There’s some unforeseen, unthought of effects in terms of economies and relationships, that will be harmed by closing this prison,” Stohr said. “But it’s also true that in our state, as in many states, we’ve been incarcerating far too many nonviolent people for many years, for minor drug offenses for all kinds of crimes where they could have been in the community.”
