An advisory panel of Clark County leaders tasked with developing a recommendation to replace or upgrade the county’s aging and overcrowded jail has come to a key conclusion that’ll likely shape the future facility.Last week, the 24-member Correction Facility Advisory Commission determined it would move forward under the assumption that the jail will need 850 to 880 beds by 2050, up from 590 now. The determination will guide the rest of the commission’s work, which is scheduled to wrap up this summer. The projected number of beds the jail will need relies on variables that could change.Clark County Council Chair Eileen Quiring welcomed the development.“They chose the upper end of the range for beds, and I believe that is wise, as this new facility will have to serve the county for many years to come,” Quiring said in a text message.Craig Pridemore, the commission’s chair, said the number of beds the jail will require is a critical question that the group extended its timeframe to answer. If a new jail is too small, Pridemore said, the same problems will arise. But he said if the new jail is too large, its operating costs could become a burden for the county, similar to Multnomah County’s never-opened Wapato Jail.To answer the question of how many beds the jail will need, the commission appointed a subcommittee that worked with Justice System Partners, a consultant contracted with the city of Vancouver. The subcommittee looked at “policy levers,” or variables that could affect the jail’s future population.
