Closed

THIS IS AN INVITATION FOR BID. PLAN AND SPECIFICATIONS ARE AVAILABLE. PROJECT NUMBER: CO FLAP LPL 10(1) PROJECT NAME:LAKE NIGHTHORSE ACCESS TYPE OF COMPETITION: FULL AND OPEN Competition with HUBZone Price Preference PROJECT DESCRIPTION: Lake Nighthorse is located approximately 1.7 miles southwest of the town of Durango along La Plata County Road 210. The terrain is mountainous, with elevations varying from 6899 feet to 6986 feet. The Lake provides access for recreational activities, including fishing, boating, and swimming. The Scope of Work is to improve the existing roadway surface from the entrance station to the boat launch area, as well as upgrade the existing parking lot at the Swim Beach Area with a paved surface, all proposed as Schedule A, 3R/3R+. The proposed roadway improvements are to provide a full depth reclamation with cement to a depth of 5 inches and then add a 3-inch overlay of asphalt. The parking lot will receive 4 inches of new aggregate base with a 3-inch overlay of asphalt. SCOPE OF THE WORK: The alignment will follow the existing roadway with some minor alignment adjustments, mostly to accommodate improved ditch conveyance. The profile was adjusted in select areas to raise the grade in the distressed roadway to minimize utility conflicts and lower profile to minimize fill in the FEMA Zone A floodplain. Full closures of the road and parking lot must be coordinated with CO, considering visitor patterns identified by the City of Durango.
