(Portland, OR) -- The City of Portland is facing a lawsuit accusing it of violating the Americans with Disabilities Act by failing to keep sidewalks clear of homeless camps. A group of ten Portlanders with disabilities filed the lawsuit in U.S. District Court on Tuesday. The group argues a significant number of city sidewalks do not currently comply with applicable federal statutes and regulations due to tent encampments and debris. The lawsuit seeks a federal court order for the city to keep all sidewalks clear and to build or buy emergency shelters for those who would be displaced by the clearing of sidewalks.
