MINUTES CITY COUNCIL OCTOBER 8, 2008 Aquatic Plant Management Specialist with the DNR, who indicated that a full eradication will not happen. The Administrator indicated that Mr. Vanderbosch will be revising the plan he previously prepared to indicate the level of eradication that will be acceptable. He has indicated that a maximum eradication of 5 acres is acceptable for large bodies of water, and has suggested that 3.5 acres may be the most that will be approved for West Savage Lake. The Administrator reported that it is an expensive undertaking to contract for eradication. The Administrator suggested an economical option would be for the City pay the cost of the chemical if there are residents on the lake willing to apply it. Blesener asked for clarification on the outlet weir (normal level). The City Administrator noted the correspondence from the Watershed indicating that the top of the weir is 895.4, which was raised from 895.1 in 2006 to compensate for the tip in the outlet pipe. The Administrator noted the need for the DNR to modify their information to correspond with the 895.41eve1. Blesener pointed out that the 100-year flood elevation is only two to three inches below the Smith's garage floor elevation. The Administrator reviewed task 3 for dredging the wetland at Jackson and Demont. The City Engineer will haue plans and specs ready for this work by the end of the month to be completed over the winter. He will include alternates for the sediment plumes in areas of Savage Lake noting that access to these areas will be difficult. Task 4 relative to evaluation/installation of storm water improvements. The Administrator noted that the installation of rain water gardens in the Savage Lake drainage area is the most reasonable option. Surveys were recently mailed to property owners in the drainage area to determine the level of interest. Survey information is due by October 15`h. The Administrator indicated that the plan would be to have these rain water gardens installed next summer. Task 5 calls for the evaluation of a street sweeper purchase. The Administrator reviewed the two types of sweepers, noting that the regenerative air sweeper is favored by the Watershed as it picks up the fine particulates which carry the most contamination. The cost of a regular sweeper is estimated at $140,000 versus $200,000 for the regenerative air sweeper. The Administrator indicated that the Watershed has been approached relative to funding a portion of this cost as a demonstration project. The Administrator also indicated that the cost of this equipment could be included in the City's Capital Improvement Budget or funded with LGA dollars depending on the level of future LGA funds. Blesener suggested that another option would be a joint purchase with another city, and suggested that City staff explore this option. The
