Disadvantages: <br />The detisity of residential development is somewhat higher than for <br />Options 1 and 2; the lift station would be in a higher traffic area and <br />providing an access road may be more difficult since Troy Lane is a <br />private road. <br />The west end of the route is wooded, so some tree loss is unavoidable. <br />Pipe could be installed by directional boring to minimize tree loss, but <br />this construction technique is more expensive than open cut. <br />Construction would disturb about 300 feet of 18'*’ Avenue in Plymouth <br />along with an adjacent concrete sidewalk. <br />Easement costs are likely to be moderately high. <br />Estimated Cost:SI80,000-5200,000 <br />Option 4 <br />Description: This proposal involves vsithdrawing water from the southern tip of the <br />southeast bay of Mooney Lake. The w ater would be carried south under County Road 6, <br />then east along the south ditch adjacent to County Road 6. Fhe withdrawii water would <br />be discharged to Pinetree Pond (State protected water 27-822w). This option would <br />involve installation of approximately 1,900 feet ol force main and gravity pipe. <br />Advantages: <br />Disadvantages: <br />Easement costs are likely to be lower because most of the route is <br />within existing Hennepin County right-of-way. <br />There is little elevation change, which will minimize the size and cost <br />of the lift station. <br />The density of residential development is somewhat higher than for <br />Options 1 and 2; lift station would be in a higher traffic area and <br />providing an access driveway may be difficult. <br />The route f'om the lake to County Road 6 is wooded and very steep at <br />the lake. <br />The pipe will have to be jacked under County Road 6, which is <br />exoen.'Ive. <br />Ea-en ent costs are likely to be moderately high. <br />Estimated Cost:$210,000-5225,000 <br />Mooney Lake Outlet <br />Feasibility Study
