topography is dominated by two high areas located in the northwest and southeast corners of the site which both slope toward a north- south trending drainage way. The drainage way enters the site at the northeast corner and exits at the southwest corner. There is approximately 25 feet of relief on-site. Surface elevations range from 32 to 57 feet, City of Madison Datum. The land surface would be altered by the borrow activity, but actual topographic changes would be small (approximately 2-8 feet) where the clay is removed. Soils Soils on the Droster-Homburg site consist primarily of silt loam soils on 0-2% slopes, with an area of slightly steeper silt loam soils (2-6% slopes) near the northwest and southeast corners. Unconsolidated glacial deposits at the site consist of 2 to 8 feet of silty clay loess underlain by silty sand glacial till. The materials suitable for constructing a sanitary landfill clay liner are found in the silty clay loess deposits. Dane County proposes to remove all suitable liner material to a depth of approximately six inches above the silty sand glacial till. A minimum of six inches of silty clay loess above the silty sand glacial till will be left in place to aid in holding soil moisture and to promote plant growth for more rapid restoration. Topographic Map A topographic survey of the proposed borrow source has been performed and a map (P/a., 5\. # 1 ) prepared to show physical features and characteristics; including relief, surface water drainage and surrounding land uses. II. OPERATIONS (To Be Performed by Dane County) Topsoil Stripping and Stockpiling All available topsoil will be stripped from the borrow area to a depth sufficient enough to expose any and all suitable clay material, taking all practicable care to avoid incorporation of any of the underlying sterile soil. Any natural loam, sandy loam, silt loam, silty clay loam or clay loam humus,-bearing soils will be considered topsoil and, therefore, will 1J be salvaged. The topsoil thus stripped from the borrow area will be either stockpiled on-sjte so that it can be sold or reclaimed, or it will be placed directly on the borrowed areas provided that they have been prepared to receive the same. Excavating and Transporting Clay Material Soils suitable for clay-liner construction which exist at the Homburg- Droster site will be excavated and transported to the site of the proposed Dane County Sanitary Landfill No. 2.
