Sand Trail Phase II
The project is located on the Cordova Ranger District and will repair and mitigate future failures of the first 1.70 miles of the 12.20-mile USFS Sand Trail #229. The mitigation includes bank armoring with riprap, placing 3-inch-minus subgrade aggregate as backfill behind the riprap (targeting about 2–4 ft behind the placed riprap), and placing D-1 aggregate on the trail running surface to harden it for ATV use. The majority of the trail is 6–8 ft wide, requiring additional clearing and minor excavation depending on equipment, and construction must occur during low-water periods with small channel diversions to dewater bank locations. Work must be performed when five consecutive days below 30°F are reached, and small diversions for bank armoring may use a dozer or excavator in the stream channel or along the bank. This acquisition is a total small business set-aside under NAICS 237990, Other Heavy and Civil Engineering Construction, with a $45,000,000 small business size standard.
