The Owls Nest Road Slide HP AML Reclamation Project is located in Leslie County, Hyden, Kentucky at 37°10’03.90″N latitude and 83°21’13.60″W longitude just east of Hyden KY. Directions to the site are; from the Hal Rogers Parkway in Hyden, Kentucky Leslie County,
take the Hyden Exit (Rt. 118) to Rt. 421 (approximately 3.5 miles). Turn left (South) on 421 through the town of Hyden and turn left at 2nd light onto Hwy 80 and travels across the bridge (Middle Fork of KY River) and turns left onto Owl’s Nest Rd. 200 ft. from the end of the bridge. Follow Owl’s Nest Rd. for approximately 2 miles. The slide is located on the left and partially blocking the road.
The active mudslide has been dealt with by Leslie County road personnel for months, removing material and debris from roadway to maintain access for residents. AML is now proposing to reduce future problems by excavating the pre-law push over slide as Owls Nest Road Slide HP AMLRP. Unstable slide material will be removed from the hill side using the strip to rock excavation method for the slide area and material will be placed in proposed waste areas. Due to limited work space a temporary stream crossing is proposed for traffic control as material is removed from slide area. Long term drainage control devices will also include class II ditches, excavated rock ditches and HDPE pipe. Silt Barriers – Bales & Fence along with Rock Checks are proposed for proper silt control at the toe of the slide and waste areas. Roadway stone bid item and Bituminous Repair are included for “in kind” repairs to public roadways as needed to facilitate reclamation work. Filter Fabric and geo-grid have been included as base for ditches. Class II/III rock will be used as directed.
All excavated material will be wasted within nearby waste areas at coordinates 37°10’04.57″N latitude and 83°21’11.63″W longitude, and an existing auger bench just east of slide area at coordinates 37°10’07.41″N latitude and 83°21’00.22″W longitude
A Hydromulch & Hydroseed bid item is included to revegetate the site/waste areas at the end of construction. Seedbed preparation and Agricultural Limestone bid items are included for the waste areas. A utility relocation bid item is included to replace “in kind” qualifying features as disturbed to facilitate the abatement plan.
Trees of 3” or greater at breast height on auger bench waste area will be removed during dormant season; all other areas are previously disturbed and/or unstable.
