The recommended building elevation for this area was <br /> determined from the Flood Evaluation Storm, which was a worst-case scenario storm for this area, a <br /> 100-year, 24-hour, Type II storm, under wet conditions. The Flood Evaluation Storm was used in areas <br /> where there was limited outlet capacity and storage,to set a freeboard elevation. Therefore,895.2 feet is also <br /> the flood elevation for this area. <br /> We would recommend not deviating from the recommended building elevation. The outlet for the wetland <br /> goes through the lot in question. If the wetland floods, the water will either go into the basement of the <br /> proposed house,or out into the street where it will sit because there is a low spot in the intersection. There <br /> will be nowhere else for the water to go. Historically, allowing a variance from the recommended building <br /> elevation will affect the next home owner who will question why they are having flooding problems,and why <br /> the City allowed the construction of this property when there were known flooding problems. <br /> Therefore, we do not recommend deviating from the recommended building elevation. If you have any <br /> further questions,please feel free to contact me. <br /> Sincerely, <br /> r.Wits\. <br /> Beth Peterson <br /> Project Engineer <br /> BCP/sh/RJK <br /> c: Rocky Keehn, SEH <br /> F:\projects\mn\mound\9901\c\ericson.n08.wpd <br /> SHORT ELLIOTT <br /> HENDRICKSON INC.
