<br />Assumptions made in the above table:
<br />1) 2000 Census will confirm a year 2000 population of 7,800 persons living in about 2,800 homes, with an
<br />additional 220 homes vacant
<br />2) During the period 2000-2010, Orono will build approximately 600 new dwelling units, an average of 60
<br />units per year, significantly higher than in the past few decades due to the added higher density housing in the areas along Highway
<br />12. Of these 600, approximately 400 will be developed with sewer and 200 will be developed with septic systems. During the
<br />decade, approximately 85 existing homes will be connected to municipal sewer, for a net increase of 115 in homes using septic
<br />systems of. 1 he vacancy rate will remain at a constant 6%; and persons per household will drop to 2.65 by year 2010.
<br />3) During the period 2010-2020, Orono will build 320 new dwelling units, an average of 32 units per year.
<br />Of these 320, -tO will be developed with sewer and 280 will be developed with septic systems. During the decade, 110 existing
<br />homes will be converted from septic to sewer, for a net gain in septic systems of 170. and a net gain in sewered households of 150.
<br />The vacancy rate will stay at a constant 6%; and persons per household will drop to 2.50 by year 2020.

<br />Map No. 6 Figure__indicates the location of the Metropolitan Urban Service Area
<br />(MUSA) and the Metropolitan Setici SeiTicc Region within Orono for year 2000 and
<br />beyond.
<br />The MUSA and MSSR are consistent does not coincide with the boundary beuveen urban
<br />and rural Orono as exists in fact and as maintained by the policies and objectives of ^
<br />discussed elsewhere in this the Community Management Plan. As indicated in the
<br />preceeding table, forecast growih in sewer facility use will occur primarily within the
<br />Orono’s Urban Service Area, but may also o^cur in the Rural Ser\ ice Area as existing
<br />housing clusters are connected to the Orono-Long Lake Interceptor.
<br />Sewer facilities planning for urban Orono is oased upon inventory and analysis of the
<br />ten various contributing areas to the existing municipal system.
