The Habitat Outdoor Classroom at Crest View Elementary, Boulder. Completed in 1990, The Habitat continues to serve as an integral learning space for the students and teachers. Serving a dual purpose as a detention facility, its resiliency withstood the 2013 Boulder County floods by collecting as much runoff as it could, thereby minimizing the impact on the school building. Thatβs a true testament of success in our book!
