The scope of work involves repairing a driveway slide at the Keen residence. The slide area will be excavated, and the material will be transported to a designated waste area site. To stabilize the driveway, a concrete wall on pilings, 50 feet long and 10 feet tall, will be installed as the primary support structure. To construct the concrete wall, a steel rail wall 100 feet long will be placed below, if needed. Additionally, a 9-foot-high, 54-foot-long gabion wall will be constructed along the upper hillside to provide further support. A 100-foot-long Class 2 flat-bottom ditch will be built to control water runoff from the hillside. To manage water flow across the driveway, an 18-inch HDPE pipe, 24 feet long, will be installed beneath the roadway. A silt trap will be installed at the projects lower end near Wendover Rd. and will be maintained throughout the duration of the project. The roadway ditch will also need cleaning and any possible areas on ditch side of project if needed. The slide area beneath the driveway will be excavated and the material transported to the waste area. The total project area spans 2.92 acres, with a maximum disturbed area of 1.02 acres. Of this, 0.60 acres consists of trees greater than 3 inches in diameter at breast height that will be affected. All disturbed areas will be quickly revegetated at the conclusion of construction, appropriate residential or wildlife seed.
