A proposed expansion of Seattle Children's Hospital would reasonably balance the public benefits of the project against protecting the livability and vitality of adjacent neighborhoods, city planners said. In April, Hearing Examiner Sue Tanner ruled that the city's first of evaluation the plan's impacts was inadequate, and planners released a new evaluation May 28 and that report is the basis for the new recommendation. The hospital's plan eventually would result in as many as 600 beds, up from 250 now, and 2.4 million square feet of building space, up from about 900,000.
