Review Agenda Without objection from Council, Mayor Love proceeded with the single item on the Agenda for the evening. 2. SHOREWOOD OAKS STORMWATERISSUES Engineer Brown introduced Pete Willenbring, a hydrologist a principal of WSB & Associates, the City's consulting fIrm. Mr. Willenbring stated he had spoken with residents of the Shorewood Oaks subdivision in effort to bring resolution to the storm water drainage issues in that area of the City. He then explained the process he had followed regarding gathering public input and information on this issue. Mr. Willenbring stated the general problem was a concern by area residents that the general drainage system that ran through Shorewood Oaks just west of Freeman Park overflowed during heavy rainfall. This problem was exacerbated by the overflow of storm water to the area from Freeman Park. Mr. Willenbring then outlined three alternatives to reduce overflow or reduce infIltration of water to the area. One of the alternatives involved Don Aslesen, of Shorewood Oaks, whose overflow seemed to be more extensive than in the past. Mr. Willenbring stated, while he had not noticed a change in his observations, he wanted all parties present to understand the drainage pattern currently being utilized was part of the drainage plan approved for the Shorewood Oaks subdivision at its inception. The fIrst option for remedy involved placement of gutters on Mr. Aslesen's home with the water being routed to the street to avoid percolation into his foundation. The second alternative involved a paved overflow route from Freeman Park between the two homes where water currently overflowed, and onto Shorewood Oaks Drive. This paved route would be constructed of approximately 6 to 8 feet of bituminous from the drainage apron area noted near Freeman Park to the curb line of Shorewood Oaks Drive.

The third option included conduction of water through an open swale where the storm water overflowage would run into an open channel along the western border of Freeman Park and directing the water to an outflow area north of Shorewood Oaks subdivision. Mr. Willenbring noted this channel could also house a large storm water pipe at additional expense for materials, labor. His cost estimates assumed did not include easements and other property control matters. In response to Council's question, Mr. Willenbring explained the third option included direction of water to the proposed Freeman Park Wetland Interpretive Area project. Engineer Brown explained with regard to water quality, he had hoped the water would flow to the Interpretive Area; however, he was concerned for the timing of the project as it related to application and implementation of grant monies obtained for the proj ect. Discussion ensued regarding the options presented and how the proposed third alternative would potentially impact the homes and park in that area. Don Aslesen, of Shorewood Oaks Drive, thanked the Council for hearing this issue and working to find a solution to the problem. He stated he was content to assume responsibility for the water that fell on and around his house; however, he was more inclined to favor the second alternative of laying asphalt pavement with curbs to try to get the overflow to the street where it could be directed appropriately. Bill Healy, of Shorewood Oaks Drive, reviewed the history of the issue as it related to his property. He stated he thought it important to reduce infiltration of water to the home sites as well. . Engineer Brown stated he believed Mr. Healy was amenable to having a six foot wide trail along his property. Engineer Brown stated he wanted to be certain that all parties involved knew that the water currently drained as it should according to the original drainage plan for the Shorewood Oaks subdivision, and whatever alternative was chosen, the drainage flowed as it should in that part of the City. Engineer Brown went on to explain the trail would not decrease the amount of infiltration to the area, but would merely redirect the flowage to the street where it could be routed to an appropriate spot. He stated he believed this alternative to be cost effective. Discussion ensued regarding the specific outflow pattern to be established by the bituminous drainage trail. Mr. Willenbring stated he was uncertain that a faster overflow rate would be attained with the trail approach. The overflow water would not infiltrate the ground in that area, however, and he was hoping to be able to utilize berm and ridge concepts along with the trail idea to maximize the direction of the overflow. Discussion ensued regarding the potential timeline for the project. Mayor Love stated he liked the dual use of the solution in that it provided an overflow area that would benefit the residents in that area, and would also provide an additional paved trail entrance to Freeman Park for the local residents. Without objection from Council, Engineer Brown stated he would present additional information on this topic at the next Regular Council meeting . . . .
