CMP Part 4C. Comnrehensive Sewer Policv Plan <br /> Orono has sufficient land available in the Rural Area for the level of rural <br /> unsewered development currently forecasted. Likewise, Orono has sufficient land <br /> in the existing urban area and in the few areas re-guided in 2000 from rural to <br /> urban development, to allow for the forecast levels of urban development. The <br /> urban and rural development forecasts have been derived from careful analysis of <br /> available land on a parcel by parcel basis, taking into account recent development <br /> trends and the City's intended development types and densities for each parcel. <br /> In the period 1980-1999 Orono added approximately 500 new residential <br /> connections to the municipal sewer system, the majority of which were the result <br /> of installation of sewer lines to serve existing residential development. Many of <br /> the neighborhood housing clusters served were adjacent to a metropolitan <br /> interceptor and made use of interceptor injector stations. <br /> In the period 2000-2008 an additional 400 new residential units were connected to <br /> the municipal system. Approximately half of these were connections for new <br /> multi-family dwelling units; most of the remainder were connections of existing <br /> homes in neighborhoods where new sewer laterals had been installed. Infill <br /> development in the urban area accounted for a small number of these additional <br /> units. <br /> During the period 2008-2030, anticipated residential connections will be from <br /> three primary sources: 1) new urban-density residential development occurring <br /> along the Highway 12 corridor in north central Orono; 2) connections of existing <br /> homes in neighborhoods previously retrofitted with municipal sewers to solve <br /> sewage treatment problems; and 3) additional retrofitting of neighborhoods within <br /> the Shoreland areas added to the MUSA in 2000. The primary impacts will be to <br /> the LS-60 interceptor service area. While Orono's other interceptor service areas <br /> will experience only modest flow rate increases, Orono flows to LS-60 are <br /> eapected to double by 2030, primarily due to new residential development, but <br /> partially due to additional commercial and institutional development. Because <br /> most of the planned urban-density housing in this area is expected to be <br /> completely developed by 2020, Orono's total flows are expected to be at the high <br /> end of Met Council's flow estimates for 2010, but nearer the low forecast for <br /> 2020 and 2030 (see Table 4C-12). <br /> Orono's projected sewer facility use and capacity needs are indicated in Table <br /> 4C-13. Population and household projections are included. These are based upon <br /> actual building permit records during 2000-2007 as well as on City expectations <br /> for future development based on current and planned zoning and extension of <br /> sewers to the areas added to the MUSA in 2000. Future capacity needs for <br /> potential future MUSA expansions under the criteria listed herein, are not <br /> included in these projections. <br /> City of Orono Community Management Plan 2008-2030 Page 4G�3 <br />
