Permit#2012-00828 <br /> 1910 Shoreline Drive <br /> Dear Melanie: <br /> As requested, we have reviewed the wetland boundary and buffer area at 1910 Shoreline Drive. We offer the <br /> following observations, comments and recommendations for your consideration. <br /> 1. I reviewed the wetland boundary and buffer in the field on August 30,2012 and agree with the <br /> wetland boundary as marked. However, final approval of the wetland boundary is the responsibility of <br /> Minnehaha Creek Watershed District(MCWD). A copy of any permits and approvals required from <br /> MCWD should be 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"preserve"wetland in the MCWD's Functional Assessment of <br /> Wetlands inventory, which requires a 50 foot buffer per City code. <br /> b. Common buckthorn, Tatarian honeysuckle and Garlic mustard were found in the wetland <br /> buffer area and are considered to be invasive plant species. Any invasive plant species found <br /> within the buffer area must be removed. Therefore, a Vegetation Management Plan including <br /> methods for removal and control of all invasive plants 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 /> � <br /> , . . � . 1 7 <br /> Mark L.
