804.1 Description. This work shall consist of furnishing and placing approved selected topsoil at the locations
shown on the plans or as directed by the engineer.
804.2 Material. Topsoil shall be obtained from sources approved by the engineer. Topsoil shall be a fertile,
friable and loamy soil of uniform quality, without admixture of subsoil material, and shall be free from material such as hard clods, stiff clay, hardpan, partially disintegrated stone, pebbles larger than one inch in diameter and other impurities. Topsoil shall be relatively free from grass, roots, weeds and other objectionable plant material or vegetative debris undesirable or harmful to plant life or which will prevent the formation of a suitable seedbed.
804.3 Construction Requirements.
804.3.1 The engineer shall be notified sufficiently in advance of the opening of any material source to permit the
engineer to prepare for necessary checking and measurement. Topsoil shall be secured from areas from which the topsoil has not been previously removed either by erosion or mechanical methods. The soil shall not be removed in excess of the depth approved by the engineer. The contractor shall furnish the source of material, unless otherwise shown on the plans. During the period of removal of the topsoil material, the site shall be kept drained, and when all material has been removed, the site shall be left in a neat and presentable condition to the satisfaction of the engineer.
804.3.2 The surface on which the topsoil is to be placed shall be free of all loose rock and foreign material
greater in any dimension than one half the depth of the topsoil to be added. The surface shall be raked or otherwise loosened just prior to being covered with topsoil. Topsoil shall be placed and spread over the designated areas to the depth shown on the plans. After settling, the completed work shall conform to the thickness shown on the plans. After spreading, all large clods and foreign material shall be removed by the contractor.
804.4 Method of Measurement. Topsoil will be measured to the nearest cubic yard, based on area multiplied
by the average depth as determined by the engineer.
804.5 Basis of Payment. The accepted quantity of topsoil will be paid for at the contract unit price, including
hauling from any distance.
