Portland Trails connects local residents to the great outdoors with a three-part mission. It aims to create and maintain a 50-mile network of trails, engage people in trail and land stewardship, and promote outdoor recreation and human-powered transportation. On a daily basis, the organization's staff coordinates with local governments to build trails that connect natural spaces with the existing pedestrian and bicycle network. They also hold regular educational events to teach the public about health, recreational activities, and reducing the impact of transportation on the environment. Demonstrating their commitment to this mission, the office only employs one truck, which runs exclusively on biodiesel fuels.
