The overall cost of the Crestline Elementary School fire is projected to spiral to $22 million by September when a replacement school opens, officials with Evergreen Public Schools said Wednesday.The updated cost estimate followed Tuesday’s news that the Feb. 3, 2013, fire was human-caused and that law enforcement had identified a juvenile suspect in the case.Dylan Mork, 17, of Vancouver is scheduled to appear in Clark County Juvenile Court on May 21 on a charge of second-degree arson. The three-alarm early morning fire destroyed the school, at 13003 S.E. Seventh St., and displaced 500 students and 50 staff for the rest of last school year and all of this year.The $22 million estimate includes only Evergreen Public Schools’ costs; it doesn’t account for the cost of fighting the fire or fire investigators’ time.Of Evergreen’s total, $18 million is the cost to build a new school at the same site. That includes demolition, construction, parking lot, landscaping and furnishings. The school district estimates that other costs will reach $4 million, including temporary housing for last school year and the current school year, additional student transportation, staff changes and moving from temporary quarters to the new Crestline in August.
