“Cornerstone Environmental was key to helping us to complete the appropriate environmental analysis for a Recreational Trails Program Grant for the Fort Tuthill Bike Park. This was a daunting task for us, given that the bike park lies within the boundaries of a National Register of Historic Places site. Cornerstone handled all of the necessary steps to include in our submissions to Arizona Department of Transportation, Arizona State Parks, and the Arizona State Historic Preservation Office.

Cornerstone’s sponsorship of this volunteer driven, free-to-the-community project has been greatly appreciated!”
