(Portland, OR) -- Portland Mayor Charlie Hales says the project to clear out homeless camps along the Springwater Corridor is being delayed by a month. Hales says cleanup will begin on September 1st instead of August 1st, in response to requests from social-service providers and advocates who want more time to relocate campers. Portland police are increasing patrols along the corridor until September 1st, citing "urgent public safety issues and environmental damage."
