G. S-fence Sediment Control System shall be installed before the application of other erosion <br /> control or soil stabilization materials in the same area. <br /> Measurement for Payment <br /> Measurement will be by the lineal foot of S-Fence installed estimated at five hundred feet. <br /> Project Manager will measure the lineal feet of S-Fence installed and accepted, and report the <br /> measured footage to Contractor. The price bid shall include all costs for labor, materials (S- <br /> Fence provided by DRMS), equipment and all other items necessary for installation of the Ertec <br /> S-Fence as described in these specifications. Payment will be made only for the unit price bid <br /> in Item 3.0 of the Bid Schedule, and as work is completed and accepted by Project Manager. <br /> ITEM 4.0 INSTALL BERM <br /> Install 4 foot high by 12 foot wide berm along the western side of the site running parallel to the <br /> South Arkansas River for approximately 250 linear feet and along the northern side of the site <br /> paralleling the river for another 250 linear feet, for a total of 500 feet. The purpose of this berm <br /> is to prevent flow from entering the site. The berm will start on the slope to the south of the <br /> site. There is an existing berm between the western and northern sections of the berm. The <br /> eastern end of the berm will connect with the bank of the storm water pond. The berm slopes <br /> must not exceed 3:1. <br /> Material for the berm will be sourced from the approximately 3,000 cubic yard pile of <br /> carbonaceous material stockpiled onsite. The location of this material is shaded in purple on <br /> the Berm and Grade Map. The new berm will be revegetated as part of Item 8.0 Revegetation. <br /> See Berm and Grade Map for the location of the berm and the location of the material for berm <br /> construction. <br /> Measurement and Payment <br /> Measurement will be made at the unit price established in Item 4.0 of the Bid Schedule. <br /> Measurement for payment will be made to the nearest linear foot of berm constructed <br /> estimated at 500 feet. Payment will be approved by the Project Manager upon completion of <br /> this item. Such payment will be considered full compensation for all labor, materials, <br /> equipment, and all other items necessary and incidental to the completion of this bid item. <br /> ITEM 5.0 SITE GRADING <br /> The remainder of the carbonaceous material stockpiled on site after berm construction will be <br /> approximately 2,000 cubic yards. The location of this material is shaded in purple on the Berm <br /> and Grade Map. The entirety of this material will be used to grade the entire area, indicated as <br /> red hatched area on the attached Berm and Grading Map. This 2 acre area will be graded <br /> towards the existing storm water pond to the north from the slope to the south, the new berm to <br /> the west and the current mining excavation to the east. The final ground surface will maintain <br /> positive drainage towards the storm water pond at an average grade of 3.5%. See Berm and <br /> Grade Map. <br /> Page 12 of 16 <br /> 7/23/23 <br />
