The applicant states on page 4 of the SerFer Pit Groundwater Monitoring Plan that baseline data will be <br />collected from the piezometers on a monthly basis (collected prior to dewatering operations).

Please specifically address the mitigation plan pertaining to the cottonwood trees located on the site.
