This includes Page Eleven Forest Ridge Subdivision; Lot 8; Block 1 April 30, 1994 careful placement of soil material into liner. Any perforation of the PVC liner material will require patching in a method that exceeds original manufacturer's strength. Rock, pea gravel, and filter sand are to be hand leveled to proper depth (tolerance within 0.01 feet) in filter, taking care not to allow mud or fine soil material into the filter or rock layers. This would include mud or fine soil material into the filter or rock layers. This would include any soil material picked up by excavation machinery buckets while loading specified material. Contractor should estimate filter materals volumes such that allowance is made for wastage of material in contact with ground at site. Work .on the sand filter may be suspended at Engineer's discretion due to inclement weather conditions such as rainfall. The sand filter and material stockpiles will be completely covered by a tarp overnight during construction until finished. Filter internal construction should be accomplished in one day's time. The Engineer will reject any sand, round rock or pea gravel that does not meet specifications or is contaminated in transit or while handling. If such material is placed in the filter, all soil material may be required to be removed and replaced with new material. 1.
