affairs. (b) Legal, engineering, and planning assistance will continue to be on a retainer basis. Waste Management and Water S92ply. Sanitary Sewerage System. At present centralized sanitary sewerage facilities serve only the Hoffman s Corner area of the community and a short segment of Schuneman Road north of T.N. 61 (see. Figure 10).. Vadnais Heights has. provided sanitary sewers along the municipal border with Gem Lake. A new beltline interceptor sewer line was completed in 1976 along the eastern border of Gem Lake. The City Engineer has designed and updated to 1981 a Comprehensive Sewer Map for the future development of the City (see Figure 10). This design includes existing and proposed alignments of sanitary sewer lines as. well as the diameter and capacity of each section of pipe. Policies: (a) It is the policy of the City to extend sewer mains as needed as shown in Figure 10. (b) On -site sewage disposal systems will not be allowed where there exist service limitations such as wetness, low soil percolation. tests and other unfavorable .soil conditions. (.See Figure 11, Gem Lake Soil iMlap.) (c) Further written I orking agreements with Vadnais Heights will be sought as necessary to coordinate required extension of sewerage service through. their territories. (d):Appropriate on -site disposal regulations will be adapted and enforced in those areas not served by :the centralized sanitary sewer system. Stagi.nq of Sewerage Facilities. The next areas to be served in Gem Lake will be in the "South District" See Figure 10), with the first action occurring in the east central portion of that District in the '82-'85 'period. Other sewer main extensions shown in Figure 10 will be. provided only if a ;professional engineering assessment in conjunction with the implementation of the on -site sewage disposal ordinance and policy a) 'above identifies the need for such extensions. The estimated average day sewer flow for 1990 is 0.073 MGD. This results from the existing per day flow of 0.041 MGD and the estimated flow of 0.032.MGD from the new L-D8 District coming in in the '82-'85 period; On -Site Waste Disposal.. Gem Lake. will adopt an on -site disposal ordinance modeled after the present Dellwood Minnesota Ordinance, providing regulation consistent with WPC-40 for construction, maintenance, inspection and manitor- ing of on -site systems, to apply to Those areas not served by the central sanitary sewer system. (See Chapter 8 "Plan Implementation.) Water Supply System. At present there is no public water d?stribution system within Gem Lake. All residential" and non-residential development within the community is served by privately developed wells. Public water distribution mains are located in White Bear Lake, and in Vadnais Heights. Policies: (a) A centralized water distribution system should be developed within Gem Lake based on a comprehensive water service plan. The system might either be developed based on a well supply within Gem Lake or by attachments to either the Vadnais Heights or White Bear Lake system or both. (b.) 'dater service should be extended at the same time in the same priorities as the sanitary sewerage service in order to minimize street reconstruction and traffic disruption. Storm _Dra nacre_ System. 'There is no storm drainage system within Gem Lake other than ditches alongside roads within the corporate limits. Two portions of Gem Lake drain internally into depressions with no surface outlet (see Figure 3 ` -46-
