(recommendation)See Attached Diagram. <br /> 1. Fill Material(Clay with a Mixture of Granular) <br /> a. Clay will provide the necessary Cohesive characteristics for a(1.1)slope. <br /> b. Granular will provide the necessary Drainage Characteristics to help prevent Waterlogging. <br /> 2. Anchors, Pipes and Miragrid 5T. <br /> a. Anchors create stability of fill to existing dirt plane. <br /> b. Pipes provide for attachment of Miragrid 5t to the Anchors. <br /> c. Miragird 5t. provides soil stabilization and internal Strength. <br /> d. Topsoil promotes lowgrowth erosion control vegetation such as Crown Vetch. <br /> Maintenance. (recommendation.) <br /> 1. Ground Cover(Crown Vetch& Bird Foot Tree Foil.) Homeowner must keep supplied necessary <br /> seed incase of dyeout. Recommended keep 2-5 pounds in storage. Water every two days until <br /> ground cover has taken root. <br /> 2. American Excelsior Erosion Control Blanket. Installed after project is completed and home <br /> owner must keep in stock 2 rolls(8'X 90')in case of washout or erosion due to large downpour <br /> after installation. If erosion occurs call contractor fix erosion and reseed and cover with erosion <br /> control blanket. <br /> 3. Homeowner must immediately contact contractor incase of problems after installation. <br /> 4. The silt fence must be kept up and well maintained until 90%of project is well rooted and <br /> vegetated. <br /> 5. The Homeowner has the responsibility to keep over 90%of the project covered with lowgrowth <br /> ground cover such as Crown Vetch. <br /> We recommend the Crown Vetch and American Excelsior Erosion control blanket for the following <br /> reasons. Recommended Maintenance. <br /> Crown Vetch is used by the DOT along side roadways where there are slopes such as 1:1 and <br /> through experience have had better success than sod for erosion control. <br /> American Excelsior Erosion control Blanket. <br /> A.Interlocking Curlex(Curled, Barbed)Wood fiber Mat. <br /> 1. Conforms to the soil to prevent erosion by holding soil and seed in place during revegetation. <br /> Protects form water flow, wind, and rain drop erosion. <br />
