H.SEEDING PREPARATION 1.Contractor shall resolve any surface or subsurface drainage problems and construct permanent erosion control structures. 2.Remove all rocks, roots or other materials that may interfere with seedbed preparation. 3.Perform the major filling, shaping and smoothing of gullied or severely eroded areas. 4.Have soil tested to check pH and fertility levels. Apply lime at rate specified in seeding specifications on the plans. 5.Work all lime and fertilizer into the soil to a depth of 2-3 inches with a small disk, harrow or rake operated across the slope as much as possible. 6.Firm the soil bed where possible. Do not over pack the soil to ensure compacting does not restrict water and root penetration into the soil. Whenever groundwater is encountered, the CONTRACTOR shall make every practical effort to secure a dry trench bottom before laying pipe. The CONTRACTOR shall provide, install and operate sufficient trenches, sumps, pumps, hose, piping, well points, etc. to depress and maintain the groundwater level below the base of the excavation. If the CONTRACTOR is unable to remove the standing water in the trench, the CONTRACTOR shall over-excavate the proposed bottom grade of the sewer bedding, and place not less than three (3) inches of No. 8 crushed stone in the over-excavated area. The CONTRACTOR shall keep the site free of surface water at all times and shall install drainage ditches, dikes, pumps, and perform other work necessary to divert or remove rainfall and other accumulation of surface water from excavations. The diversion and removal of surface and/or groundwater shall be performed in a manner which will prevent the accumulation of water within the construction area. UNDER NO CIRCUMSTANCES SHALL SURFACE WATER AND/OR GROUNDWATER BE DISCHARGED TO, DISPOSED OF OR ALLOWED TO FLOW INTO AN ACTIVE SANITARY SEWER SYSTEM.
