We offer <br /> the following observations,comments and recommendations for your consideration. <br /> 1. I reviewed the wetland delineation report on September 10,2012 and agree with the wetland boundary <br /> as marked. However, final approval of the wetland boundary is the responsibility of Minnehaha Creek <br /> Watershed District(MCWD). A copy of any permits and approvals required from MCWD should be <br /> submitted to the City prior to any land disturbing activities. <br /> 2. The proposed construction has the potential to adversely impact the wetland which will trigger the <br /> wetland protection ordinance requirements.Therefore,the following should be considered: <br /> a. This wetland is listed as a"management 3"wetland in the MCWD's Functional Assessment <br /> of Wetlands inventory,which requires a 16.5 foot buffer per City code. <br /> b. The wetland delineation report indicated that the buffer area is"manicured lawn dominated by <br /> Kentucky blue grass." The area of manicured lawn within the buffer area must be removed <br /> and native vegetation will need to be established in its place. MnDOT seed mix 350 is <br /> recommended for upland buffer areas. A Vegetation Management Plan, including methods <br /> for removal and control of any invasive plants and a schedule of native vegetation <br /> establishment, should be submitted for review. <br /> c. Wetland Buffer markers should be placed at the upland boundary of the buffer edge located at <br /> lot lines and changes of buffer edge direction and spaced a maximum 200 feet apart. <br /> d. A $2,000 escrow should be submitted by the Owner to cover the cost of buffer development if <br /> not completed by the applicant. <br /> Please contact me if you have any questions or need additional information. <br /> Sincerely, <br /> BOLTON&MENK, INC. <br /> Mark L.
