rural development forecasts have been derived from careful analysis of available land on a parcel bv parcel basis, takine into account recent development trends and the City ’s intended development types and densities for each parcel. In the period 1980-1999 Orono added approximately 500 new residential connections to the municipal sewer system, the majority of which were the result of installation of sewer lines to serve existing residential development. Many of the neighborhood housing clusters served were adjacent to a metropolitan interceptor and made use of interceptor injector stations. In the period 2000-2020. a poiuon of the anticipated residential connections will be from the few remaining urban-densitv housing clusters in the rural area: but the majority of new connections will be from newurban-densitv residential development occurring along the Highway 12 corridor in north central Orono. The primary impacts will be to the LS-60 interceptor service area. While Orono’s other interceptor sei^vice areas will experience only modest flow rate increases. Orono flows to LS-60 are expected to more than double bv 2010. primarily due to new residential development, but partially due to additional commercial and institutional developemnt. Because most of the planned urban-densitv housing in this area is expected to develop in the next 10 years. Orono’s total flows are expected to be at the high end of Met Council’s flow estimates for 2010. but nearer the low forecast for 2020 (see Table ). The combina tion of thg-^v; factors , plus the interceptor injector statio n ca paci ty, will permit connection of certain exis ting housing clusters al ong the interceptorroute plus providing-cap a city fernonTesidential urban development, all within the confines of €>rono^s land use plan and the interceptor design ca pa city. Orono’s projected sewer facility use and reserve capacity needs-is are indicated in the following table. Two populati on Population and household projections are shown: the first is based upon the Nletiv^politan Council's projected population level: the second (lower) figure is the City of Orono's projection included. These are based upon actual Kiiilding pemiit records for the last ten years , as well as on City expectations to: future development based on current and planned zoning. CMP 6-42 I
