ex pected urban development and inereased sewage flows shown as reserve capacity in the tables on Page and in the CSPP Appendix. The 1999 review of Orono Sewer Connections (See Appendix ) included an analysis of expected development within each of the 31 existing MUSA areas as well as the areas proposed to be added to the MUSA. For purposes of sewer facilities planning, this expected growth is divided into f9t»r five categories: 1) INCREASED FLOW FROM EXISTING USERS. In the case of building expansion or increased occupancy, higher flows could be expected through existing service co inections. No new municipal sewer facilities are required. 2) INFILL URBAN DEVELOPMENT. In the case of development of existing vacant urban properties, new connections can be expected through existing service stubs. No new municipal sewer facilities are required. 3) NEW URBAN DEVELOPMENT. Certain areas within the existing and proposed Urban Service Area are und'^veloped or developed at less than the zoned densities. New sewer later <s can be expected to be e.xtended into these areas as identified on Map No. 11. Facilities plans for this growth are discussed below. 4) EXISTING UNSEWERED DEVELOPMENT. As of this datc,-thcfe are thfcc small pockets of ex isting residential dcvelopmenHvtthin the urban area which are not provided with scwcf lateral scfviee. Facilities plans for eonneetton-ef these units arc discussed beimv. Within Orono’s urban service area, virtually all existing developed areas ha\ e been provided with sewer lateral service. However, within the rural ser\ ice area a number of developed properties which are now (or arc proposed to be) within the MUSA have vet to be provided with municipal sewer laterals. 5} NEW SHORELAND DEVELOPMENT. A number of properties within Orono’s rural service area are also within defined Shoreland areas and have been incorporated into the MUS.A to allow their development at rural densities with municipal sewer. Sewer facilities planning for rural Orono is the function of the on-site management program. The Metropolitan Council’s Water Qutdity .Management Policy 13 (Pg W12/79) states that "THE PREFERRED METHOD OF WASTEWATER DlSPOSAfc FOR-NBW RURAL DEVELOPMENT IS THE INDlVlDUAh-QN SITE SYSTEM”. Consistent with this philosophy, and with Orono's commitment to maintenance of permanent rural area.s in the community, Orono has in 1978 pioneered in the establishment of a full- service On-Site Systems Management program designed to assure the continued performance of on-site systems. In terms of sewer facilities planning, the On-Site Systems Management Program can be divided into four categories of activity: CMP 6-44
