Mark Putnam, the director of “All Home,” formerly the Committee to End Homelessness, is photographed outside his office on Sept. 29, 2015, in Seattle. On any given day, more than 10,000 people in King County experience homelessness, according to All Home. The committee is adopting a new strategic plan that aims to make homelessness a rare, brief and one-time occurrence.  (Lindsey Wasson/The Seattle Times)
