<br /> Map 4C-2 indicates the location of the Metropolitan Urban Service Area
<br /> (MUSA) within Orono for year 2010 and beyond. The MUSA does not
<br /> coincide with the boundary between urban and rural Orono as discussed
<br /> elsewhere in this Community Management Plan. As indicated in the preceding
<br /> table, forecast growth in sewer facility use will occur primarily within Orono's
<br /> Urban Area, but may also occur to a limited extent in the portions of the Rural
<br /> Area that are within the MUSA.
<br /> Sewer facilities planning for urban Orono is based upon inventory and
<br /> analysis of the various con�ributing areas to the existing municipal system.
<br /> The review of Orono Sewer Com�ections (See Tables 4C-3 and 4C-4) includes an
<br /> analysis of expected development within each of the 4� existing MUSA areas as
<br /> well as the areas proposed to be added to the MUSA. For purposes of sewer
<br /> facilities planning, this expected growth is divided into five categories:
<br /> 1) INCREASED FLOW FROM EXISTING USERS. In the case of building
<br /> expansion or increased occupancy, higher flows could be expected
<br /> through existing service connections. No new municipal sewer facilities
<br /> are required.
<br /> 2) INFILL URBAN DEVELOPMENT. In the case of development of
<br /> existing vacant urban properties, new connections can be expected through
<br /> existing service stubs. No new n�unicipal sewer facilities are required.
