Refer to Section 01410, SURVEYS, for requirements regarding preconstruction <br /> surveys. <br /> B. The OWNER will conduct detailed topographic surveys of site to document "as- <br /> built" prepared subgrade on the base and slope of the retention basin, pan <br /> lysimeter, terminations of geomembrane liner, and the location of the interior crest <br /> of anchor trenches. The crests and bottom of the drainage ditches, culvert inverts, <br /> and pipe inlets and outlets shall also be documented. All surveys will be <br /> performed in accordance with Section 01410, SURVEYS. <br /> 1. Measure area elevations on minimum 50-foot-grid over entire impoundment <br /> area and at all breaks in grade. <br /> 2. Measure linear dimensions a minimum of 100-feet on center. <br /> 3. Plot results of topographic surveys to scale of 1 inch equals 50 feet and <br /> provide survey information in electronic format to QA/QC CONSULTANT. <br /> 4. QA/QC CONSULTANT will check the survey. The EARTHWORK <br /> CONTRACTOR shall not construct the lining system until survey approval <br /> is provided by the QA/QCCONSULTANT.

Dispose of water in a manner that will not damage <br /> adjacent property. When dewatering open excavations, dewater from outside the <br /> structural limits and from a point below the bottom of the excavation when <br /> possible. Design dewatering system to prevent removal of fines from existing <br /> ground. <br /> PART 4 MEASUREMENT AND PAYMENT (Refer to Section 01200, MEASUREMENT <br /> AND PAYMENT PROCEDURES) <br /> Forward Compost Facility Stormwater Improvements <br /> 02300 16 EARTHWORK <br />
