The highly trafficked Oklahoma Flats Trail in Aspen was overly steep at a grade of over 20%. It crossed into a driveway, creating a high potential for hazardous accidents. The design and permitting required multiple steps, a land use stream margin review, and issuance of a permit from Engineering. RFE created CDOT formatted specifications and summary of approximate quantities that were consistent with City Parks trail standards. The trail centerline is now only 12% and the sculpted uphill soil wall integrates well with the neighborhood.
