In 1975, the City of Orono directed the City Engineers at <br />that time, Mccombs-Knutson Associates, Inc., to conduct a <br />preliminary engineering study of sanitary sewers for the Stubbs <br />Bay (NE) area. That study included groundwater sampling which <br />was interpreted by the Enqineer as indicatinq surface and shallow <br />groundwater contamination. The study proposed that a collection <br />system be constructed to serve Tonka Avenue, Crestview Avenue, <br />and Eastlake Street. <br />Two alternatives for treatment and disposal were reviewed. <br />Thy first involved pumping to the proposed Long Lake -Orono <br />Interceptor at Fox Street between Old Crystal Bay Road and Willow <br />Drive. The interceptor was never installed in that location, <br />hence that is no longer a viable alternative. The second <br />proposal was to construct a community drainfield, sized to serve <br />a total of 42 houses or 15,700 gallons per day. The proposed <br />location was an open field at the southwest corner of Leaf Street <br />and Bayside Road, which has now been subdivided into residential <br />lots. <br />The drainfield proposed at the time would not be feasible <br />under current standards, mainly due to the seasonal high water <br />table found at that site. A review of the Hennepin County Soil <br />Survey maps indicates that the soils on the north sides of Stubbs <br />Bay are generally not well suited for septic systems and a large <br />volume system would likely experience problems. In order to find <br />the area and soils potentially suitable for a community <br />drainfield, one would have to go east of Leaf Street or north of <br />Watertown Road, in either case requiring a collection system and <br />long force main in addition to the community drainfield. <br />Estimated costs of treatment/disposal system serving only <br />the 37 unit Stubbs Bay NE sub -area: <br />26,200 s.f. drainfield at $3.00/s.f. _ $78,600 <br />6 acres land at $10,000/acre raw value = 60,000 <br />Septic/settling tanks, 13,000 gallon capacity = 10,000 <br />Site work = 30,000 <br />Total $178,600 <br />or $4,700/unit in addition to the cost of collection system and <br />forcemain to the site. <br />21 <br />
