GRADING PLAN
Earthwork Notes1.All embankments (fill) placed on this project are to be controlled fills, and placement is to be observed andtested by the geotechnical engineer.2.All excavation is unclassified.3.Materials - Suitable excavated material shall be used in forming the embankments. Materials classified as OL,OH, or Pt are not suitable for use as controlled fill. The on-site high plasticity soils are generally suitable forre-use as controlled fill provided that proper drainage, grading, and sloping away from the structures ismaintained both during and after construction. Blasted or “shot” limestone rock can be utilized for fill providedthat the maximum particle size of the rock not exceed 12 inches and sufficient amounts of soil fines be mixedwith the rock to fill in open voids between the rock particles. The nesting of boulders in the embankment isprohibited. The material to be used in embankments shall be free of frozen or organic materials such as leaves,roots, grass, weeds, and all other material not consistent with construction of a stable, homogeneous fill.Embankments shall not be constructed on frozen ground.All proposed fill materials should be approved by the geotechnical engineer prior to placement as controlledfill, and representative samples should be obtained one week prior to placement of that material to allow timefor completion of the necessary laboratory tests.4.Site Preparation - All vegetation and topsoil shall be removed from areas upon which embankment will beconstructed. Topsoil shall be stockpiled as required by the E&S plan. Vegetation shall shall be converted tomulch and used for E&S control or removed frm the site by the contractor. All sloping areas upon which fill is tobe placed should be benched or “notched” so that a smooth interface between existing ground and new fill willnot be present. Each layer of fill should be benched into the existing ground a minimum of 3 feet horizontallyand the depth of one fill layer. Flat areas upon which fill is to be placed shall be deeply plowed to allow forbonding with the existing material. The controlled fill slopes and embankments should be constructed at thedesigned 2H:1V slopes or flatter.5.Formation in Layers - Unless otherwise provided, embankments shall be constructed in successive layers no
