Disadvantages: <br />Density of residential development is somewhat higher than for <br />Options 1 and 2; lift station would be in higher traffic area and <br />providing access road may be more difficult, since Troy Lane is a <br />private road. <br />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 />Would disturb about 300 feet of 18 “* Avenue in Plymouth along with <br />an adjacent concrete sidewalk. <br />Easement costs are likely to be very high. <br />Estimated Cost:$180,000-$200,000 <br />Option 4 <br />Description: This proposal involves withdrawing water fi^om the southern tip of the <br />southeast bay of Mooney Lake. The water would be carried south under County Road 6, <br />then east along the south ditch adjacent to County Road 6. The withdrawn water would <br />be discharged to Pinetree Pond (State protected water 27-822w). This option would <br />involve installation of approximately 1,900 feet of force main and gravity pipe. <br />Advantages: <br />Easements 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 />Disadvantages: <br />The density of residential development is somewhat higher than for <br />Options 1 and 2; lift station would be in higher traffic area and <br />providing an access driveway may be difficult. <br />The route from 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 />expensive. <br />Easement costs are likely to be very high. <br />Estimated Cost:$210,000-5225,000 <br />^1
