Minnesota Department of Natural Resources Metro Waters - 1200 Warner Road, St. Paul, MN 55106-6793 Telephone: (651) 772-7910 Fax: (651) 772-7977 August 31, 1999 City of Roseville Thomas Paschke, City Planner 2660 Civic Center Drive Roseville, MN 55113 RE: Mark & Terri Hanson Subdivision Proposal, Lake McCarron's (62-54P), City of Roseville, Ramsey County Dear Mr. Paschke: DNR Waters has received (August 19, 1999) the survey (dated July 8, 1999) for the proposed subdivision of property owned by Mark & Terri Hanson for property located at 304 North McCarrons Boulevard. The Hanson's are proposing to subdivide a single riparian lot into two 35,000 square foot riparian lots located in the southeast quarter of Section 13, Township 29 North, Range 23 West. In your cover letter, you asked for guidance on the placing of structures on the Hanson lots. From an ecological point of view, the best location for homes on these lots is on the property within 120' of Lake McCarrons Boulevard North. These sites are recommended because they are not located on steep slopes, which are prone to erosion. In addition, these sites have the benefit of being located relatively far from Lake McCarrons. Many Cities consider swimming pools to be structures and subject to the same setback requirements as houses. The swimming pool should be constructed close to the house of the property to allow the plumbing of the house to be used to drain the pool. Your letter also asks for guidance concerning the removal of vegetation in the area between the home and lake. In general, noxious and exotic upland vegetation may be removed without receiving a City Permit. However, the removal of shrubs and trees will require the approval of the City ofRoseville. It is only fair to explain that many Cities choose to regulate only the cutting of trees that are greater than 3" or 6" in diameter. The primary goal of retaining the vegetation on a lot is to preserve the aesthetic experience that people have when they are on Lake McCarrons. However, it is allowable to remove selected tree branches and trees to preserve the view ITom a house to the lake. In addition to the above comments, we have the following detailed comments to offer: 1. Lake McCarrons (62-54P), a DNR Protected Water, is located on the Hanson Property. Any work that is done below the ordinary high water (OHW) level of841.4' (NGVD, 1929) is under the jurisdiction of the DNR and may require a DNR Permit. Currently, it appears that there are no plans for work below the ordinary high water level. However, should any plans be made for work at, or below, the OHW, then DNR approval will be needed. Should there be any wetlands on the Hanson Property that are not under DNRjurisdiction, then these wetlands will fall under the jurisdiction of the Army Corps of Engineers and the Ramsey- Washington Metro Watershed District. Other DNR employees may submit comments in response to these regulatory programs.
