The small-rock slope protection method consists of excavating and backfilling the footing trench, placing rock slope protection fabric as shown, and placing small rocks on the slope. Place a layer (six inch minimum) of The State of Maryland pledges to provide constituents, businesses, customers, and stakeholders with friendly and courteous, timely and responsive, accurate and consistent, accessible and convenient, and truthful and transparent services. When slope protection is paid by volume, review the plans and quantity calculations in the resident engineers file to determine if there is sufficient detail and accuracy to be used in the project records. Before construction of any type of slope protection, review the plans, Standard Specifications, special provisions, any pertinent preliminary test data, and the location of the installation. Also, ensure the contractor does not drop rock into place; otherwise, cracking or breaking may occur. The plans indicate the minimum depths of foundations. If the slope is steeper than 2:1, do not use rounded boulders and cobbles. endobj DM[2TI=lGQx7 UoFK1: V;39LFOr7LxPF{BL3he6X^@v[QhWiF!l3F) RTIBfx0.T F%n3h80Q,`[2xa%VLP /WD@j rK .9{N[#o/Fad#OK6YeqsyHl2M)V]/Nf(V?!1Oaw)fM 8JG)31m. 10 0 obj The equilibrium soil-to-geotextile system that allows for adequate movement of a liquidin the plane of the geotextile over the service lifetime of the application.
