Remove abandoned utility service lines from areas of excavation. Cap, plug, or seal abandoned lines at source of connection and identify termination points at grade level with markers, after notification is provided to the City representative. Accurately locate and record abandoned and active utility lines rerouted or extended on project record documents. 3.03 SITE GRADING B GENERAL Perform grading within contract limits, including adjacent transition areas, to new elevations, levels, profiles, and contours indicated. Provide uniform levels and slopes between new elevations and existing grades. Obtain approval of scarified subgrade surfaces by City's representative prior to filling operations. Scarify, dry, and compact soft and wet areas; remove and replace unsuitable subgrade materials with an approved fill material. Take corrective measures before placing fill materials. Thoroughly scarify existing soil surface to a depth of 10" and as shown on the Soils Report and verify scarification with City's representative prior to placing fill material in mounded areas. Spread approved fill material uniformly in layers not greater than 12" of loose thickness over entire fill zones of planting areas. 1. Lift thickness requirements may be modified by City s representative to suit equipment and materials or other conditions when required to assure satisfactory compaction. 2. Place and compact each layer of fill before placing additional fill material. Repeat filling until proposed grade, profile or contour is attained. 3. Suspend fill operations when satisfactory results cannot be obtained because of environmental or other unsatisfactory site conditions. Do not use over-saturated fill materials. Do not place fill material on over-saturated subgrade surface. 4. Grade surfaces to assure positive drainage and to prevent ponding and pockets of surface drainage. 5. Protect finish graded areas from traffic and erosion. Keep free of trash and debris. Repair and reestablish grades in settled, eroded and damaged areas. If, in the opinion of the City, the completed site grading does not reflect the intent of the Contract Documents, an independent surveyor may be hired to verify the grades. If the grades are correct, the City will pay for the survey. If the grades are incorrect, the cost of the survey will be deducted from the Contract price. Earthwork 02310-5

3.04 BACKFILLING / FILLING FOR PAVING & WALLS Before filling, remove debris, large rocks, formwork and loose material. Proof-roll areas to receive fill with rubber tired roller of sufficient weight. Weak areas or areas where excessive pumping is noted shall be removed, and if required by the City, replaced with select fill. Prior to placing fill, scarify surface to a depth of 6 inches. Moisture content of loosened material shall be such that first layer of fill will readily bond to surface. Top 6 inches shall be free from rocks larger than 3 inches diameter. Place in maximum 8-inch lifts and compact per ASTM D 1557 at optimum moisture content (-1% to +3%). This lift and compaction requirement does not apply to planting areas. Moisten fill to allow drying to correct moisture content before compaction. Do not place fill on subgrade that is over-saturated. Paving subgrade per plan. Allowing for total thickness of finish paving and base material, fill under paving to bring subgrade to proper elevation. Soft areas that develop under construction operations shall be scarified, aerated or moistened. Compact to full depth required to obtain specified density for each layer. 3.05 EXCAVATING It is the Contractor's responsibility to investigate the likelihood of caliches or hard rock excavation. The City will not provide any additional compensation to the Contractor for hard rock or caliches excavation. 3.06 FINISH GRADING Grade uniformly with rounded surfaces at tops and bottoms of abrupt changes in plane. Hand grade steep slopes, areas that are inaccessible for machine work and areas around existing plants. Slope graded surfaces to drain water away from structures, walls, etc.; minimum slope is 1/4 inch per foot. Grade areas to elevation and slopes indicated without depressions causing pocketing of surface water or humps, producing localized runoff and erosion. Ponding of water on site is not allowed. Finish surfaces to be not more than 0.10 foot above or below established grade elevation. 3.07 DRAINAGE Provide drainage of the working area at all times. Earthwork 02310-6

3.08 DISPOSAL OF WASTE MATERIALS Legally dispose excess excavated material, including rock from site. 309 CLEANING Upon completion of earthwork operation, clean areas within contract limits, remove tools and equipment. Provide site clear, clean, free of debris and suitable for site work operations. Remove and dispose of properly off site all rocks and other debris from grading operations.
