III. Sanitary Sewer The proposed sanitary sewer for the North Long Lake area is shown on Figure 2. The proposed sanitary sewer for the Long Lake Country Club areas is shown on Figure 3. From the review of the project site, the routes shown on the figures are recommended from a construction standpoint. The North Long Lake area would be served by construction of a lift station on Long Lake Boulevard near the shore area of Long Lake. A force main would be installed along Long Lake Boulevard and continue west along North Sixth Street where it would tie into a manhole in the Long Lake Country Club area. Because of the steep slopes and difficulty to construct sanitary sewer along the lake, five of the homes on the south side of Long Lake Boulevard will be served with grinder pumps and force main to the gravity sewer. An option to provide gravity sewer in the back of the lots along Long Lake using directional boring is not economically feasible. If open-cut construction methods were to be used there would be too many trees lost and a high ground water table along the lake may make the constniction cost prohibitive. Proposed storm sewer improvements for the North Long Lake area are also shown on Figure 2. The existing catch basin on the north side of Long Lake Boulevard would be removed and a new catch basin and manhole with a pipe extending towards the lake would be constructed. The upgrading of the storm sewer will be completed in accordance with policies adopted in the comprehensive storm sewer plan. The Long Lake Country Club area would also be serve by construction of a lift station at the south end of Lake View Terrace. A force main would be installed along Country Club Road and then south along North Brown Road were it would tie into an existing manhole in the Sugarwood Development. Alternate layouts for the forcemain to serve North Long Lake and Long Lake Country Club are shown on Figures 2 and 3. These layouts would reduce the project cost slightly. The drawback for these two alternate layouts is the easements that would be required to construct the forcemains may be difficult to obtain. Sanitary Sewer Improvements I
