_ 2 III. Development Framework Issues •The Development Framework map indicates that Orono is as urban fringe community (see Attachment A). The southern part of Orono around Lake Minnetonka is shown as "planned urbanization, 1975" although actually only the south- western part of the city has local sewer service. The northeastern section of the city around Long Lake and Wayzata is designated "additions, 1976-1980", and the northwest is shown as a "general rural use region". The northeast area is designated as an addition to the Urban Service Area because this was to have been part of the service area of the Orono -Long Lake interceptor as planned in 1974 when the land analysis for Develop- ment Framework was done. The chronology of events in Part II indicates that sewer facilities planning got ahead of land use planning in the Orono area, and was embodied in the Development Framework map. Now that local land use planning has been done, there is need to bring metropolitan plans into line with it if legiti- mate metropolitan interests and policies are not jeopardized by doing so. A principle of Development Framework is that the Metropolitan Urban Service Area shall contain sufficient land suitable for development to accommodate all urban development in the region through 1990 without creating undue land price inflation. The land analysis in the Framework, particularly Table 6 on page 32, indicates that there is ample land for development in the southwest Minneapolis sector even without the additional MUSA in Orono. An area in Chanhassen which will be added to the MUSA by 1980 will be sufficient to make up any deficit which might occur in the sector. Therefore, expanding the MUSA in Orono could be postponed until about 1990 without upsetting the principles of the Framework. Therefore, to make the Framework compatible with municipal planning, staff recommends that the Framework be amended by removing the addition to the MUSA in Orono. Orono's comprehensive plan, adopted'in 1974, contains policies favoring permanent low density development throughout the city, except in the urban area in the southwest corner. Orono has concluded from engineering studies that urbanization would lead to large amounts of polluting stormwater runoff which cannot all be fil- tered by the natural wetland system, and that development on two -acre lots is essential to preserve the quality of Lake Minnetonka. In 1974, the Council reviewed Orono's comprehensive plan and recommended the following: "That Orono revise its plan to include consideration of development beyond its first stage plan and commit itself to further investigation of controls and techniques to accommodate growth without undue environmental hazard." Since the MUSA will possibly have to continue to expand after 1990, and since Orono lies squarely in the path of growth in the I-394 corridor, the City is a logical place to expect urban growth after 1990. The City (&hould be aware of this and should also note that the staff's recommendation to alter the MUSA in Orono is of necessarily an endorsement of permanent low density development in the City nor of 2 -acre lot sizes. Additional investigation is needed of the relationship bete -en urban development in•.the Lake Minnetonka water- shed and the water quality of the lake. Orono's comprehensive plan submitted pursuant to the Metropolitan Land Planning Act should consider techniques for preserving the option of urban -density development sometime in Orono's future. IV. Waste Management Policy Plan An interim comprehensive sewer plan must include at a minimum: (1) a schedule of extensions of the local collection system over the next 3-5 years (including estimated number of connections and flow); (2) identi- fication of. an interim service boundary; (3) an indication of how unsevered areas will develop and what methods of waste disposal will be permitted; and (4) adoption of MWCC rules and regulations. The Orono CSP deals with all of these items. A. Local Collection System Extensions and Interim Service Area In addition to the main sewered portion of the City in the southwestern corner, there are several small pockets of development in Orono that are now sewered or shown in the CSP as potentially re- ceiving service in the future. All of these are in the rural service area. The largest pocket in- cludes the Hackberry Hills subdivision, the Orono Industrial Park, and Orono High School, all of which presently receive service through the Long Lake system. The CSP indicates that service to Hackberry Hills is temporary; it does not but should indicate the permanent service solution and when this will be programmed. Other severed areas lie adjacent to Wayzata on the east and presently receive service from Wayzata. The CSP states that there is capacity in the local sewers for more flow than presently generated but that the 2 -acre minimum lot size makes it unlikely that capacity will be used. The other area show for future sewer service is the Morningside area of Medina which was included in the approved interceptor service area on a limited basis. The City has stated its understanding that service to Medina must come through local lines and be negotiated between Medina, Orono and Long Lake. The City has also indicated by resolution its opposition to the proposed Vo - Tech school in Medina which was not approved by the Council for inclusion in the interceptor service area. The Orono CSP also identified 15 isolated areas of existing development presently served by on-site disposal systems. The CSP indicates that, as a general policy, the City will implement one of the following solutions when it determines there are pollution or sewage disposal problems in any of the 15 areas. (1) regulate future building to what can be satisfactorily handled by private, on-site disposal systems;
