This site was previously addressed under the Frank Hatcher HP AML Reclamation project and Frank Hatcher HP Repair AMLRP. Weather related erosion issues have developed after the completion of these projects including erosion of the channel downstream of an existing 18 dia. culvert, sedimentation in the concrete block-tied mat and Class II ditch channels, erosion of the Class II and grass swale ditches upstream of the culvert and sediment deposition on the first bench above the residence. This project will remove the sediment obstructing flow in the established ditches on the first bench above the residence to existing outlets. Adjacent and downslope of the strip to rock area, the eroded grass swale ditch and impacted Class II ditch will be replaced with a 2 foot flat bottom Class II ditch. The 18 culvert will be replaced with a 24 HDPE culvert, adjusting its direction of flow onto a newly installed concrete block-tied match ditch and ultimately into the existing headwall just downstream. An 8-inch diameter pipe draining the access road ditch beyond the replaced culvert will also be replaced and the flow path adjusted to outlet onto the newly installed concrete block-tied mat ditch.
