I-25 Conservation Corridor Master Plan

Douglas County, Colorado

Preserving over 100,000 acres of open space along Colorado’s booming Front Range

Over 73,000 vehicles travel the Front Range corridor between Colorado Springs and Denver on any given day. This area is growing fast. Population is increasing at a clip of 1,000 per-month and construction continues to change the skyline. Unrelenting sprawl is depleting valuable open space, wildlife habitat and scenic views. Doubling land values have rendered every acre within the corridor vulnerable to development. South of Castle Rock, sweeping views of the mountains emerge amidst a pristine foreground of rolling grasslands, mesas and historic ranches. This unique 17-mile stretch of Interstate 25, approximately 32,000 acres, lies undeveloped following the implementation of the I-25 Conservation Corridor Master Plan, the result of a strong strategic vision coupled with unprecedented cooperation among conservation organizations, government entities and private landowners.
