It’s one small section of Denver, but a frequent stop for first responders. Denver firefighters said they took nearly 2,200 calls to the area around rescue missions and homeless camps in downtown Denver. On Monday, the city of Denver dubbed the area a public health risk in the area. City officials cleared homeless camps and cleaned the sidewalks and streets between 21st and 24th streets, and Arapahoe and Lawrence streets. “That little section of the downtown area has proven to be quite an issue for us, in terms of our call responses,” said Denver Fire Captain, Greg Pixley. Pixley said most of the calls firefighters get to the area are medical related. “People in need of assistance, if they got hurt, perhaps there was an assault or something like that,” he said. Fires are a concern, too.
