Specifications include, but are not limited to: The Kenneth Ray Lewis site is located off No. 1 Hollow Road in Johnson County, KY at coordinates N 37 46' 31.43", W 82 45' 45.00". A concrete block retaining wall was constructed behind the Lewis residence as part of a previous AML project, however a hillside outside the wall's confinement area has broken loose and threatens to cut off access to several residences further into the hollow. To address these concerns, 150 L.F. of 9' tall, non-reinforced concrete wall (type II) (AML 30-20-2) will be constructed adjacent to the existing wall, extending to the southwest. The wall will follow an existing access road as is shown on the plans. In addition to the wall subdrain, 180 L.F. of roadside ditch will be dug out and re-established to control drainage created by the wall. The area in front of the new wall will be stripped to rock to prevent further instability which could endanger road accessibility, and the roadside ditch in the immediate vicinity will be dug out and re-established. Other drainage behind the house will be addressed by constructing 50 L.F. of subdrain (AML 22-30-1) and outletting that subdrain in the location identified on-site by the engineer. Some chain-link fence in this area may be disturbed by the work and will need to be replaced as directed by the engineer
