SECTION 02312 <br /> SWALE CONSTRUCTION <br /> L DESCRIPTION <br /> A. Fine grading of swales shall be accomplished after the existing ground has <br /> been excavated and compacted to within + 0 . 2 ft. of the design elevations . <br /> Fine grading of the swale areas will be done by a motor grader unless <br /> otherwise approved or directed by the Engineer. Hand dressing will not be <br /> required except where shown on the Drawings or in confined areas where <br /> equipment operation is restricted. <br /> B . The Contractor shall maintain and keep open and free from leaves, sticks, <br /> rubble, and other debris, all swales graded by him until final acceptance of the <br /> work. <br /> C . The finished grade shall be completed and shaped to a surface which varies no <br /> more than 0 . 1 foot above or below the Plan elevations except that, <br /> adjacent to pavement, grates , or sidewalk, the swale shall be graded to match the <br /> edge of the pavement, grate or sidewalk. <br /> D . In areas where sodding is required, finished soil grade shall be set 0 . 2 foot <br /> below the plan elevation to compensate for sod thickness . <br /> E . Compaction to a specific density will not be required unless so directed by the <br /> Engineer. However, swales shall be compacted to a firm, even surface true to <br /> grade and cross section. All swales must be rolled. <br /> F . Fine grading of the swale areas shall preferably be done prior to paving the <br /> asphalt wearing course . If the Contractor chooses to fine grade the swale <br /> areas subsequent to paving, he must exercise extreme care when dressing <br /> areas adjacent to pavement areas to avoid damage to the pavement. No <br /> handling of swale material shall be permitted on the pavement surface . <br /> G . After final dressing of the swales, the Contractor shall seed or sod them as <br /> required by the Plans in accordance with Section 02204 or 02205 of the <br /> Specifications_ <br /> C : \ Down1oad \ techspec - 02312 . doc <br /> 02312 - 1 <br />
