City of Orono <br />September 21, 2016 <br />Page 2 <br />Permit Requirements <br />Lowering or upsizing the outlet culvert to lower the high water level and reduce the extents of flooding <br />would require permitting from the Army Corps. of Engineers (ACOE) and the Minnehaha Creek <br />Watershed District (MCWD). The application would need to demonstrate a "minimal impact" solution to <br />a specific need with respect to all other reasonable alternatives and no increase to the flood stage <br />downstream. The MCWD permit could be decided on in about a month, however, the ACOE permit <br />could take 6-12 months to obtain a decision. Also, at this time, it is difficult to predict if the regulatory <br />agencies would approve lowering or upsizing this culvert without a completed design and supporting <br />data. <br />Fee F.ctimnte <br />Based on the scope of services described above, we propose a not -to -exceed fee of $7,000 to be billed on <br />an hourly basis. Our fee estimate is based on the following assumptions: <br />• Study area will be limited to the watershed upstream of the Ferndale marsh only. <br />■ No Construction Plans or permit applications will be generated as part of this proposal. <br />4 No surveys will be performed as part of this proposal. <br />• Wetland delineation services will not be required. <br />Please let me know if you have questions or need additional information. <br />Sincerely, <br />Bolton & Menk, Inc. <br />David P.
