• Ms. Michele McPherson <br /> Page 2 <br /> June 21, 2002 <br /> 3. Given the location of the drainage and utility easement and the lot lines, Lot 4 will need <br /> to construct a driveway through the drainage and utility easement either covering the <br /> wetland or adjacent to the lot line. It appears the lot line is in its current location to <br /> provide the appropriate setbacks form the existing home on the site. Perhaps the lot line <br /> could be configured slightly differently to provide a larger opening for the driveway on <br /> Lot 4. <br /> 4. This plat should be reviewed by the Sherburne County Highway Department relative to <br /> any additional easement needed along the County Road 33 frontage and/or any <br /> requirements for the intersection of 207th Avenue with County Road 33. <br /> The existing contours appear to indicate a drainage ditch on the east side of County <br /> Road 33 flowing north which is not within the proposed right-of-way of County Road 33. <br /> The County should look at this situation carefully and determine whether or not they <br /> need additional right-of-way and/or easement to cover this drainage ditch. <br /> 5. There were no drainage calculations provided with the submittal package. However, a <br /> proposed road is shown to flow easterly with a set of catch basins near the opening to <br /> the cul-de-sac and small-diameter storm sewer flowing to the wetland on the north side <br /> III of the road. There will need to be a water quality pond constructed before any discharge <br /> is allowed to the existing wetland. Drainage calculations, including a pond design need <br /> to be submitted, reviewed, and approved prior to final approval. <br /> 6. There appears to be a natural flow around the east side of the cul-de-sac from Lot 5 <br /> through Lot 6 and also a natural flow out of Lot 5 through Lot 4 at approximately the <br /> midpoint. Both of these areas should be covered by additional drainage and utility <br /> easements. <br /> If you have any questions regarding any of these comments, please call. <br /> Sincerely, <br /> Howard R.
