Estimated Length of Project:
(Substantial Completion) + 90 Calendar Days (Final Completion)
The project will correct drainage and install sediment control in the intermittent drain behind the home. An old 0.7-acre slide has on a hillside above the Scalf residence and sent material flowing down approximately 620-ft of the ephemeral-intermittent drain but has since since stabilized. Material that has flowed into the yard has been previously cleaned up by the landowner.
Project limits include 4.75 acres, with an expected disturbance of 2 acres within project boundaries. Project limits for the offsite waste area includes 4 acres, with an expected disturbance of 1 acre. Within the stable area, a total of 0.1 acres of trees will be disturbed including two trees 5”-8” DBH in the area of the gabion weir installation, and several smaller trees along the ditch line. No trees will be disturbed at the waste area.
The project will involve rehabilitation of an existing ditch from the drain along the edge of the property to the corner of the driveway, where it enters a larger existing drain, which outlets into Jim Maynard Branch. A ditch and subdrain on the opposite side of the yard, opposite the existing ditch will be installed to carry water from the slope into the same stream. In addition, two gabion weirs will be constructed in the drains above the home upstream of the installed ditch to control the flow during heavy runoff events and provide sediment control. The yard that was previously filled with mudflow will be graded to slope towards the ditches and will be reseeded to AML specifications. Existing water bars in yard will be re-established as ECB ditches. All excess excavated materials will be placed at the offsite waste area.
