The length of the culverts to be installed will be minimized <br /> to reduce the area of the channel that will be affected. Figure G-17 shows the profile and cross- <br /> section for the Little Turkey Creek crossing. <br /> The sediment detention basin outlets will be CMP culverts. These culverts will need to be <br /> excavated through the unmined blocks of bedrock to allow the pipes to be placed at grade. <br /> Therefore, a notch will be excavated to allow the installation of the culverts based on the <br /> maximum depth required for drainage over the life of the pit development. These areas will then <br /> be filled to ensure the affected area drainage is detained prior to release. For reclamation, the <br /> fill will be removed and the bedrock cut exposed to allow a positive drainage from the reclaimed <br /> pit areas. <br /> Hitch Rack Ranch Quarry Permit Application <br /> October 3,2017 G-25 <br />
