be carried out on a 100-foot by 100-foot grid with additional survey points <br />required to define valley leach facility topographic features (i.e., toe of slope, crest <br />of slope, breaks in grade), unless otherwise directed by MANAGER. The Record <br />Drawings shall include elevations and locations for the following: <br />? Underdrain plan view showing the limits of the valley leach facility. <br />Underdrain Fill and underdrain alignment, with elevations every <br />approximately 100 feet or on every break in grade <br />? Diversion channel plan and profile view along the diversion channel <br />alignment <br />? Leak detection trench plan view showing the limits of the valley <br />leach facility, leak detection trench alignment, and leak detection <br />sumps, with elevations every approximately 100-feet <br />? Soil Liner Fill plan view showing the limits of the valley leach facility, <br />with contours of the Soil Liner Fill and Bedding Fill surface on a 10- <br />foot contour interval, including the regraded ore slopes and end <br />berms <br />? Low Volume Solution Collection piping plan showing the limits of the <br />composite liner, double liner and single liner, and piping alignment <br />with elevations every approximately 100 feet <br />? Perimeter access roads <br />? Top of Upper geosynthetics in the Pregnant Solution Storage Area, <br />including the Vertical Riser Sump and base plates <br />? High Volume Solution Collection piping plan showing the limits of <br />Phase III, and piping alignment with elevation every approximately <br />100-feet <br />In addition, the Colorado licensed surveyor will provide a surveyor's certificate to <br />be submitted in the Construction Certification Report. <br />C.
