scarified or loosened to a depth and then raked smooth and free from debris. <br />Where the soil is sufficiently loose and clean, the Owner, at his discretion, may <br />authorize the elimination of ground preparation. <br />G. Application of Fertilizer: Before applying fertilizer, the soil pH shall be brought to a <br />range of 6.0 - 7.0. <br />Contractor shall apply two (2) applications. The initial shall be fertilizer and the <br />second application shall be "weed and feed". <br />The fertilizer shall be spread uniformly over the sodded area at the rate of 436 <br />pounds per acre, or 10 pounds per 1,000 square feet, by a spreading device <br />capable of uniformly distributing the material at the specified rate. <br />Contractor shall apply applications as per manufacturer's specification. All tickets <br />from bags shall be handed over to the County Inspector. <br />On steep slopes, where the use of a machine for spreading or mixing is not <br />practicable, the fertilizer shall be spread by hand and raked in and thoroughly mixed <br />with the. soil to a depth of approximately 2 inches. <br />H. Placing Sod: The sod shall be placed on the prepared surface, with edges in close <br />contact and shall be firmly and smoothly embedded by light tamping with <br />appropriate tools. <br />Where sodding is used in drainage ditches, the setting of the pieces shall be <br />staggered so as to avoid a continuous seam along the line of flow. Along the edges <br />of such staggered areas, the offsets of individual strips shall not exceed 6 inches. In <br />order to prevent erosion caused by vertical edges at the outer limits, the outer <br />pieces of sod shall be tamped so as to produce a featheredge effect. <br />Where sodding is placed abutting paved shoulder, the contractor is to ensure that <br />the finished sod elevation is 1'/2' below paved shoulder. <br />On slopes greater than 3:1, the Contractor shall prevent the sod from sliding by <br />means of wooden pegs driven through the sod blocks into firm earth, at suitable <br />intervals. <br />Sodding shall not be performed when weather and soil conditions are, in the <br />Engineer's opinion, unsuitable for proper results. <br />Sod shall be placed around all structures, equipment pads, etc. <br />I. Watering: The areas on which the sod is to be placed shall contain sufficient <br />moisture, as determined by the Engineer, for optimum results. After being placed, <br />the sod shall be kept in a moist condition to the full depth of the rooting zone for at <br />least 2 weeks. Thereafter, the Contractor shall apply water as needed until the sod <br />roots and starts to grow for a minimum of 60 days (or until final acceptance, <br />whichever is latest). <br />01025-21 Technical Specifications <br />FAEngineering\Capital Projects\0206 5th ST SW & 43rd AVE Bridge Replacement & Roadway Improvements\CONTRACT <br />BID\Technical Specifications.doc <br />
