The altered drainage of the disposal sites has been well addressed as has erosion control measures. No work, other than 20 foot wide access roads from the lake, is proposed to take place within the 50 foot shore impact zone (within 50 feet of the lake). The city is responsible for dealing with drainage and odor complaints as well as the placement and maintenance of erosion control measures for the first year. The sediment has been tested and does not contain contaminates of concern. Top soil will be removed from the disposal sites, the bearing capabilities of the soil remaining will be verified and documented, sediment will then be placed on the sites according to the plans, top soil replaced, and the sites will be immediately seeded and mulched. The sediment placed on the Bickman, Hartman and Wapiti Park sites will contain 2% or less organic matter because they have the potential for development. There is a potential stockpile of material proposed in the southeast comer of the Bickman disposal site. Mr. Bickman is willing to take this material and offer it for sale. This stockpile is proposed adjacent to the roadway for access. It is unlikely that there will be a need for the stockpile, but it should be considered as part of the city's request. The Tim Smith property disposal site, shown on Map #4, has been added in case the Island View disposal site does not work out. The Island View site has limited area adjacent to the lake for disposal of sediment and possibly a reluctant property owner. The estimated project cost in the feasibility study does include the cost of tracking material away from the Island View site. The 2,000 cubic yards of sediment that was proposed for the Island View site would cover an area approximately 200 feet by 250 feet by 1 foot deep on the Smith property. The Smith site is close to a DNR protected stream, but the DNR indicated that with proper erosion control they were not worried about the use of the site. Mr. Smith's property has been farmed in the past and he plans to use it for a tree farm. Drainage from the disposal on the Smith site can be directed to nearby wetlands and will not affect any residences. In addition, the State Historic Preservation Office (SHPO) believes the Island View and Orono Cemetery disposal sites have significant potential for archaeological sites. A Phase I archaeological survey will be conducted on the Orono Cemetery site, but staff is arguing the logic of the Island View site having significant archaeological potential with SHPO. Wetlands on the disposal site also need to be delineated to determine that none are affected by the sediment disposal. This was not done earlier because of snow cover. Environmental Concerns
