Natural and man-made features were the primary
controlling items. These included the two
lakes, Link River, main ridge lines, the railroad
and the "A" canal. Any of these items would be
costly to cross. For this reason the local
distribution system for a district should fall
within these boundaries and only major supply
lines would cross thera at carefully selected
points. City political boundaries did control
the district locations to a degree, mainly to
simplify future administration.
Figure 2 is a generalized map of the urban
area showing the approximate district boundaries.
The district areas increase with distance from
the central business district, due to the reduction
in heating (population) density in the
suburban areas. Heating loads for each district
have not been determined, however it is estimated
that the majority are approximately equal.

Heating District Boundaries
Based on discussions with City planning
officials, a priority was given each district
as to its probable inclusion into the system.
Thus districts labeled "1" on Figure 2 would be
developed first. "2" second, and so forth. Districts
with priorities "1" and "2" have their
boundaries fairly precisely determined for planning
purposes, whereas priorities "5" and "6" have
more flexible boundary locations due to the possible
effects of future growth before these districts
come on-line.

A probable development schedule for each of
the priorities would be as follows:

It should be noted that two of the Districts
immediately adjacent to the Commercial District
were given a low "4" priority for development.
This recognizes the fact that a great portion of
these districts are already heated by individual
wells, thus some of its heating needs are already
being met by geothermal. Future development may
be based on either expanding the service load of
each existing well (from one to four houses, for
example), or by providing a heating district
similar to the other districts.
Production Field Locations
Several areas near or in the urban area have
potential as production well sites. Each area
was evaluated as to certain desirable characteristics,
which included:
1. proximity to users so as to minimize supply
pipeline lengths;
2. elevation head to provide gravity feed;
3. availability of public land for development;
and
4. information on geothermal fluids existing in
or adjacent to the site.
Based on the above criteria and geologic information,
seven areas have potential to supply the
necessary fluids for the near term or future
development of the area. In many cases, additional
geological, geophysical exploration, and/or
drilling need to be performed to verify the
existence and characteristics of the resource.
Figure 3 is a map to the same scale as the
geologic map indicating the seven sites. The
numbers also indicate the order of recommended
investigation and development of the sites. Site
1 is discussed in detail.
