. . . CUP, Steven Shoemaker January 27, 1993 Page 2 be planted. The applicant chose to implement the DNR's recommendation of a 10:1 slope on the back portion of the pond. This area would have an average depth of 3-4 feet. An unexcavated island is planned in the middle of the south 1/2 of the pond. Staff has enclosed a brochure from the DNR regarding excavation of ponds for water fowl which gives recommendations on how to properly construct wildlife ponds. DRAINAGE At the December meeting, a few neighbors were present to express their concerns with the proposed project including what affect this excavation would have on drainage in the area, traffic concerns, noise and other disruptions to a residential area. Staff feels this proposed excavation should not have an affect on drainage in the area if certain precautions are taken. City engineer, Terry Maurer, indicated if the City Council approves a general concept for the proposed excavation, the City should require more detailed plans before excavation begins (i.e., elevations of lowest floors in the area, and existing and proposed topography). These details are necessary to ensure the drainage will not be affected and to properly inspect the work in progress. Mr. Maurer's comments are available in the attached letter dated January 20, 1993. Mr. Shoemaker is considering a clay liner on the east side to ensure the pond retains water. This may be considered fill in a wetland which would not be allowed. NOISE The City ordinance regarding excavation (Section 720) places standards on these types of activities. Hours of operation are limited from 7 a.m. to 7 p.m., Monday through Saturday. Maximum noise levels shall comply with the limits established by the MPCA and the EPA. Because this excavation is in a residential area, more restrictive standards may be desired. The Planning Commission is recommending work commence no earlier than 8 a.m. SAFETY The issue of safety should be addressed in an liability. The applicant has slightly altered depth to a safer level. Staff is recommending of 3-4 feet for safety reasons. effort to limit the slope and a maximum depth FUTURE EXCAVATIONS Staff recommends the City take a look at the bigger picture regarding excavation of wetlands. A study of wetlands should be conducted to determine which ones should remain untouched and which ones the City would allow to be altered. For background information, I have attached an article from the January 3, 1993, Minneapolis Star Tribune regarding wetlands in the Metropolitan area.
