40 <br />a <br />0 <br />SECTION 2N - SWALE CONSTRUCTION <br />1. D1=SCRU MON <br />A. Fine grading of swales shall be accomplished after the existing ground <br />has been excavated and compacted to within + 0.2 ft. of the design <br />elevations. Fine grading of the swale areas will be done by a motor <br />grader unless otherwise approved or directed by the Engineer. Hand <br />dressing will not be required except where shown on the Drawings or <br />in confined areas where equipment operation is restricted_ <br />B. The Contractor shall maintain and beep open and free from leaves, <br />sticks, rubble, and other debris, all swales graded by him until final <br />acceptance of the work. <br />C. The finished grade shall be completed and shaped to a surface which <br />varies no more than 0.1 foot above or below the Plan elevations <br />except that, adjacent to pavement, grates, or sidewalk, the Swale shall be <br />graded to match the edge of the pavement, grate or sidewalk. <br />D. In areas where sodding is required, finished soil grade shall be set Q,2 <br />foot below the plan elevation to compensate for sod thickness, <br />E. Compaction to a specific density will not be required unless so directed by <br />the. Engineer. However, swales shall be compacted to a firm, even surface <br />true to grade and cross section. All swales must be rolled. <br />F. Fine grading of the swale areas shall preferably be done prior to paving <br />the asphalt wearing course. If the Contractor chooses to fine grade the <br />swale areas subsequent to paving, he must exercise extreme care <br />when dressing areas adjacent to pavement areas to avoid damage to <br />the pavement. No handling of swale material shall be permitted on the <br />pavement surface. <br />G. After final dressing of the swales, the Contractor shall seed or sod <br />them as required by the Plans. <br />. y <br />2N-1 LI <br />66 <br />
