Mr. Craig Schlichting February 10, 1999 Page 2 2. We commend the designer of the development for reducing the potential for erosion by minimizing the grading of the Twin Lake Pines site. This indicates that the designer is aware that erosion from the steep slopes on the Twin Lake Pines site has the potential of destroying any resemblance of good water quality in Twin Lake. Therefore, erosion controls on the Twin Lake Pines site need to be very good. We recommend that the developer frequently inspect the erosion controls of Twin Lake Pines site to ensure that the lake is being protected from pollution. In addition, drainage onto the steep slopes need to be carefully planned in order to protect both the lots in the development and the lake from erosion. Currently, the site of Twin Lake Pines is wooded. The existing vegetation both protects Twin Lake water quality and provides an aesthetically pleasing view for homeowners on Twin Lake. The existing vegetation adjacent to Twin Lake, and on steep slopes, should be protected through the use of deed restrictions, covenants, or dedicated easements. This would help to ensure that the property owners are aware that a buffer of natural vegetation is needed to preserve the water quality of Twin Lake and the scenic views that are important to residents on the lake. In addition, the existence of natural vegetation will be beneficial to the fish and wildlife of the area. The following comments are general and more typical of comments given for other developments: Twin Lake (62 -39P) is a DNR Protected Water. Any work that occurs below the ordinary high water level of Twin Lake is under the jurisdiction of the DNR and may require a DNR permit. The OHW of Twin Lake has not been determined. Should there be a question as to whether the work for Twin Lake Pines will be under DNR jurisdiction, then the DNR can be asked to determine, if necessary, the OHW of Twin Lake. In addition, the removal of any emergent aquatic vegetation requires an aquatic plant management permit from DNR Ecological Services (Mike Halverson @ 651- 772 - 7950). 5. It is good to see that all of the proposed structures will be built above the floodplain elevation of 875.0' (NGVD, 1929). The roads and structures of Twin Lake Pines should be constructed in accordance with the floodplain regulations of both the City of Little Canada and the Ramsey - Washington Metro Watershed District. 6. Twin Lake has a shoreland management classification of recreational development, and a 1000' shoreland management district. It is good to see that Twin Lake Pines will greatly exceed many of the minimum development standards set in the Little Canada Shoreland Management Ordinance. We recommend that a Homeowner's Association be established for the homes in this development and that the following items be made part of the covenants for the association: Page 90 A. The preservation of a buffer of uncut, natural vegetation, extending 37.5' from the ordinary high water level, or to the top of the steep slopes on the lot, whichever is greater. A covenant that is enforced by the Homeowners Association will ensure that the property owners are aware that the vegetation beside Twin Lake is essential to preserving the lake. The location of stairways to Twin Lake should be placed so as to be screened from view on Twin Lake using vegetation and topography.
