Natural Resources Conservation Service
Construction Specification SD-10 Salvaging and Spreading Topsoil
Scope The work shall consist of salvaging topsoil from borrow pits or other excavations and spreading it in the designated areas as shown on the drawings to the specified depths.
Quality of Topsoil Topsoil shall consist of friable soil reasonably free of grass, roots, weeds, sticks, stones, or other foreign materials.
Excavation Topsoil shall be salvaged from designated earth surfaces that will be disturbed by construction activities. After designated sites have been cleared and grubbed, the topsoil shall be removed from the designated areas and stockpiled at locations shown on the drawings or acceptable to the Natural Resources Conservation Service (NRCS) inspector. Objectionable materials shall be removed and buried, or disposed of, at locations approved by the NRCS inspector.
Spreading Spreading shall not be done when the ground or topsoil is frozen, excessively wet, or otherwise in a condition detrimental to the work. Surfaces to be covered shall be lightly scarified just prior to the spreading operation.
All earth fills not to be submerged shall be covered with topsoil to a depth of 6 to 18 inches measured perpendicular to the surface of the fill and placed to the neat lines shown on the drawings.
Following the spreading operation, the topsoil surface shall be left reasonably smooth and without ruts or surface irregularities that could contribute to concentrated waterflow downslope and shall be left in a condition that will permit seeding equipment to be operated without excessive smoothing.
