r <br />Zoning Fite i^l9S2 <br />November 17. 1994 <br />Page 3 <br />approach the propeny ai the m'tihucst comer »1ierc ilic property lines meet, refer to Exhibit <br />M. The mining or excavations will take place m Ok winter months The peat material will K* <br />immediately conveyed to liutienteUl ’s nursery to the north far frt>m the wetland areas The only <br />question that remains is the metlkxl or type of equipment pri>poscd to ci'inplcte the excavations <br />and transport off site. Suff has been advised that Butterfield will employ the same methtxl <br />approved in the 1989 review for Mr. Butterfield's application Ihe excavation is circular type <br />hole at a 6' maximum depth and 50' diameter resulting in the removal of approximately 200 <br />cubic yards of peat. Such 50' wkk excavations shall be made each winter season for a penod <br />of ten years until the project is completed. <br />Statf notes that most of the findings made for Ok original conditional use permit approved for <br />Butterfield in 1989 are still applicable for this reviewr. The excavation of open water areas <br />totalling .68 acres in the 150 acre wetland will have little impact on the wetland. In fact it <br />would create more positive benefiis. The engineer in 1989 nvUed the following: w ildlife habitat <br />would be enhanced, open water areas wimld provide sediment trap, varied design of slopes to <br />the open water areas would cra:our3ge more beneficial wetland/aquatic vegetation. The existing <br />over grown wetland provides little retentu>n tor runotf. It is questionable how much treatment <br />takes place. <br />Issues for Consideration <br />1.luich vear an excavation will be made removing 200 cubic yards of material. It has not <br />been made clear to the City staff what other types of land alterations shall follow the <br />excavations to insure that appropriate slopes and erosion control are maintained. When <br />will the final 'touch up* excavations be made-at the time each 200 cubic yard excavation <br />is completed or in two or eight year periods.’ <br /><*» *What kinds of equipment will be used to carry or convey the peat material from the site.’ <br />List the name of the method or type of equipment used to make the excavation lor the <br />removal. <br />4.How do we assure that the DNR standards for wildlife ponds arc maintained during this <br />interim ten year perivxl.’ <br />5.What of the safety issue--with the creation of 6’ deep, 50’ wide excavations out in the <br />middle of 150 acre wetland? Is temporary' signage necessary to warn any trespassers.’ <br />6.Why are we asked to approve a project that will be extended tor a ten year process.’ <br />This worked for Butterfield’s needs. This project could easily be completed in one <br />season What are the benefits of extending the project?
