<br />RESPONSE TO COMMENTS FROM THE METROPOLITAN COUNCIL <br />(letter from Sandra Gardebring, May 23, 1986) <br /> <br />1. Ramsey ordinances require that 25\ of soils on site must <br />be classified as Class I soils in order for construction of <br />a private sewer system. Class I soils include soils that <br />are moderately or rapidly permeable, have slopes of 12\ or <br />less and are at least 6' above the water table. <br /> <br />If sewer systems are to be developed in an area of rapid <br />permeable soils, the inclusion of loam in the bottom of the <br />trenches is the most preferred method of mitigation. If <br />that method is not suitable to the particular site, other <br />methods may be considered. <br /> <br />2. Discussions concerning access to the site from T.H. <br />10/169 are continuing between MnDOT and the City of Ramsey. <br />The comments of Met Council will be considered in these <br />continuing discussions. <br /> <br />f <br />I <br />, <br /> <br />3. The issue of density is addressed in the attached letter <br />from Ann Norris, Ramsey City planner, to Paul Baltzersen, <br />Metropolitan council staff. <br /> <br />4. Lake depths are greater than reported in the Draft EIS. <br />A lake survey conducted on May 28, 1986 found the mean depth <br />of Lake Itasca to be about 5 feet, with the deepest region <br />reaching around 8.5 feet (see Figure 29). The methods used <br />in the earlier survey (1981) are not known. It is not clear <br />if lake levels have risen five feet in five years, or if the <br />previous investigators' survey was possible incorrect. Also <br />current lake levels may be higher than normal and may <br />decline slightly as late summer and autumn approach. <br /> <br />The modeling done to estimate water quality and clarity has <br />been confirmed by on-site tests. The current water <br />transparency is relatively good. On May 28, 1986, the <br />secchi disc was plainly visible on top of the lake sediments <br />at a depth of 8.5 feet. In addition, a lake water sample <br />was collected on the same day and analyzed for total <br />phosphorus. A concentration of 0.02 mg-p/l was recorded. <br />This,is close to what was predicted from the lake model <br />(0.03 mg-P/l, p. 77 of the DEIS) <br /> <br />The lake has fairly high local recreational potential. The <br />lake is deep enough to support at least a panfisb fishery, <br />some sandy shoreline reaches would make a suitable swimming <br />beach, and a 110 acre lake is large enough for recreational <br />canoeing. Existing vegetation supports a variety of <br />wildlife inCluding loons, red-necked grebes, kingfishers, <br />and muskrats. Because the lake is surrounded by sandy <br /> <br />I <br />l_ <br /> <br />-64~ <br />
