Permit#2011-01295 <br /> 505 Old Crystal Bay Road <br /> Dear Melanie: <br /> As requested,we have reviewed the wetland boundary and buffer area at 505 Old Crystal Bay Road. We offer <br /> the following observations;comments and recommendations for your consideration. <br /> 1. I reviewed the wetland boundary and the buffer area in the field on August 30,2012 and agree with <br /> the wetland boundary as marked. <br /> 2. The proposed construction has the potential to adversely impact the wetland which will trigger the <br /> wetland protection llordinance 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. Turf grass and yellow foxtail were found in the wetland buffer area and are considered to be <br /> invasive pl t species. Any invasive plant species found within the buffer area must be <br /> removed. In areas where turf is removed,native vegetation will need to be established. <br /> MnDOT seed mix 350 is recommended for upland buffer areas. A Vegetation Management <br /> Plan,including methods for removal and control of all invasive plants and a schedule of native <br /> vegetation establishment,should be submitted for review. <br /> c. Wetland B ffer markers should be placed at the upland boundary of the buffer edge located at <br /> lot lines ani 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 haare any questions or need additional information. <br /> Sincerely, <br /> BOLTON&MENK, INC. j <br /> ex" <br /> �J- <br /> Mark L.Perry, WDC <br /> Natural Resources Specialist <br /> Cc: David Martini,Bolton&Menk <br /> Robert Bean,Bolton&Menk <br />
