Ground review by the USFS is required prior to initiation to <br />determine if additional mitigation measures are needed in these exception areas. <br />4) Surface disturbance will be minimized to the extent reasonably feasible in order to limit <br />potential impacts. Soil that is removed from all new disturbance areas will be windrowed or <br />stockpiled for use in reclamation. Topsoil will be segregated from subsoil. No soil generated <br />from excavation, slide removal or other operations shall be deposited within the WIZ of any <br />drainage with flowing water. <br />5) Before removing an trees, the trees will be designated and the removal approved by the <br />USFS prior to removal.
