Until about a year ago, Vancouver’s former City Hall was a place where powerful people brokered big deals. Recently, it’s become a place where hobos relieve themselves.Weeds have grown up to head-height, garbage cans overflow and a former fountain now sports a sheen of algae accented with floating plastic bags. In the lower level of the parking garage, used toilet paper fills one corner.The site, at 210 E. 13th St., was formerly leased by the city from the Vancouver School District. Now that the city’s out, it’s part of the school district’s purview — and it has fallen by the wayside.“I was disgusted and horrified,” said Vancouver City Councilor Jeanne Stewart, who stopped to check out her former stomping grounds when she saw the overgrown weeds as she drove by. “We’re trying to encourage people to be downtown, and we don’t get there with having what looks basically like an abandoned building.”The school district knows the former City Hall is in bad shape — so much so that they’re sending in a cleanup crew first thing Friday morning, said Todd Horenstein, assistant superintendent of facility support services.
