Green Infrastructure Technologies Used in Parking Lot Reconstruction at Century College in Minnesota
Greater Capacity, Reduced Impact
Century College, one of Minnesota’s largest two-year community and technical schools, built a new library/science building on the site of a parking lot, reducing the amount of parking on campus.
Century, whose enrollment is growing, needed to improve and expand its west campus parking lot and pedestrian spaces to increase parking, correct drainage issues and enhance connections from parking areas to the academic building.
The college’s aging west parking lot consisted of 14 acres of surface parking that drained toward the academic building. The lot’s age and configuration contributed to the need for reconstruction, and the college specifically requested environmentally friendly techniques for this project.
Increased parking with better connections and improved access enhance the experience of students and help further the college’s growth. An interconnected network of pervious paving, underground storm water storage, infiltration features and structural soil systems make this a showcase for low-impact design.
The technology and systems used in this reconstruction allowed the expansion of parking while reducing the impact of storm water on the adjacent wetland complex by improving the quality and reducing the quantity of campus storm water runoff. The result is a well-functioning parking facility that revitalizes and enhances this area of the campus.
