Green Trails

Green Trails applies the principles of ecology, sociology, and sustainability to make superior trail corridors. As trail experts with a collective staff expertise exceeding 75 years, we recognize that the creation of trail corridors today is a vastly different process than it was just 10 years ago. Growing urbanization and shrinking available open space means that a holistic and comprehensive approach to corridor design is needed. Green Trails cohesively address multiple objectives including community needs, storm water treatment, water quality enhancement, wildlife migration and barrier reduction, habitat enhancement, stewardship strategies, and public education. To accomplish this, we combine our public facilitation expertise with biological science disciplines and sustainable design principles. While regulatory requirements traditionally have been site-specific and focused on avoidance of impacts, with a one-to-one off-setting mitigation requirement, Green Trails goes beyond. It strives to understand the regional and local environmental role of the corridor and its surrounding social fabric. We enhance those functions through a comprehensive green trail corridor approach that begins with initial planning and is carried through design, construction, stewardship, and monitoring.
