of storaQS if tho 4#500 cubic yards of excavated material were to remain above the floodplain elevation of 818.0. Manager LaBounty stated that he was concerned that the success of the project was contingent upon the pumps functioning properly. Manager Lindley discouraged the use of variances that would be necessary if increased flooding were to occur. It was moved by Manag't Lindley# seconded by Manager LaBourty# to approve the application based on revised flood storage calculations based on an elevation of 810.3# rather than 808.0 as proposed by tb applicant# with the permit to be issued upon receipt of those iceros as set forth in Engineer’s report in a form and substance acceptable to staff.

On the other hand, if the fill is part of a shoreline lE^rovement for replacing lost shoreline due to erosion, the project would be consistent with the requiresMints of District rules. The Managers discussed the possibility of allowing the project to go forwai^ given the emergency public safety concerns, and requiring MnDOT to provide compensatory storage at some other location if not available at this site. Mr. Psnxei stated that ^ significant eroaion had occurred at the site, ind that District practice had been to allow compensation for up to five years of shoreline erosion that can be documented.
