•The clay soils will be excavated so as to minimize the mixing of clay soils with the underlying sands and gravels. To accomplish this, a minimum of six inches of clay material will be left in-place above the underlying sands and gravels where possible. Areas that require over excavation or filling to achieve the proposed final slopes and grades (plan sheet # ) will be covered with a minimum of six inches of available clay material. During the excavation of the clay material, the borrow area will be maintained in a well drained- condition at all times by keeping excavation areas and embankments sloped to the approximate section of the ultimate earth grade. Blading and leveling operations will be performed during the process of excavation so as to avoid washing, sloughing or deposition of materials into waterways, which would result in undue or avoidable contamination, pollution or siltation. Clay soils will be transported to the site of the Dane County Sanitary Landfill No. 2, across C.T.H. "AB" , using self-propelled rubber tired earth moving equipment. The crossing of C.T.H. "AB" will be limited to two locations. Travel by earth moving equipment on or across Lud' s Lane will be prohibited. It is estimated that approximately 175,000 cubic yards of clay material will be removed from the proposed borrow source. Excavation work at the borrow source is scheduled to begin upon receipt of the required use permit and will be substantially complete by November 1, 1984 . III. RECLAMATION ( To Be Performed By Owners) Proposed Final Grades The proposed borrow area will be cut and filled to such a degree so that, when covered to the required depth with topsoil, the finished work will be in accordance with the required final lines, grades and slopes indicated on the plan sheet. Placing Topsoil After the excavated areas upon which the topsoil is to be placed have been prepared and finished to the required lines , grades and slopes , the salvaged topsoil will be placed and spread thereon to a uniform depth of approximately six inches. The underlying soils and the placed topsoils will be mixed to a more or less homogeneous mixture and all clods and lumps will be broken down by means of harrow' s disc or other appropriate equipment to provide a uniformly textured soil. Rocks , twigs, clods that will // not break down, and other foreign matter will be removed, and the entire surface will be dressed to present a uniform appearance. Fertilizing One composite soil sample will be taken for every five acres of disturbed land and sent to the University of Wisconsin Extension, Soil and Plant Analysis Laboratory along with a completed Farm Information Sheet. The lime and fertilizer recommendations received from the University of Wisconsin Extension will be used to calculate the application rates needed to correct the soil
