the watershed, by year 2010. Under the high growth-decentralized land use plan
future scenario, the land devoted to urban uses is projected to increase to
about 5.3 square miles, or about 15 percent of the total watershed by year 2010.
It is important to note that the 85 to 89 percent of the watershed remaining in
rural uses is partly comprised of primary environmental corridor lands consist-
ing of the best remaining natural resource features, and as recommended in the
year 2010 regional land use plan, and is proposed to be preserved, largely in
open space uses through joint State-local zoning or public acquisition.       In
addition, certain other lands classified as wetlands and floodplains outside the
primary environmental corridors are, in some cases, precluded from being devel-
oped by State and Federal regulations.    Thus, the demand for urban land will
have to be satisfied primarily through the conversion of the remaining agricul-
tural and other open lands of the watershed from rural to urban uses.      Rural
land uses may be expected to decline collectively from about 31.2 square miles
in 1990 to about 30.7 square miles in the year 2010 under the intermediate
growth-centralized land use plan and to about 29.3 square miles under the high
growth-decentralized land use plan, decreases of about 2 and 6 percent between
1990 and 2010 for the two year 2010 plans considered.
POINT SOURCE POLLUTANT CONTROL PLAN ELEMENTS
This section describes the recommendations and status of implementation of the
current initial regional water quality management plan, as well as current plan
recommendations for the abatement of water pollution from point sources of
pollution in the Sauk Creek watershed--including consideration of private sewage
treatment plants, points of public sewage collection system overflows, and
industrial wastewater treatment systems and discharges.       This section also
includes a status report on the public sanitary service areas located in the
watershed.
Public and Private Wastewater Treatment Systems and Sewer Service Areas
Existing Conditions and Status of Plan Implementation: In 1975, there were no
public sewage treatment facilities located in the Sauk Creek watershed.      One
private sewage treatment plant serving the Cedar Valley Cheese Factory in the
Town of Fredonia was in operation in 1975, as shown on Map XIV-3. The status of
implementation in regard to the private sewage treatment plant in the Sauk Creek
watershed, as recommended in the initial regional water quality management plan,
is shown in Table XIV-3. As indicated in Table XIV-3, the private plant serving
the Cedar Valley Cheese Factory was recommended to be maintained and upgraded to
provide effluent quality which would be determined on a case-by-case basis as
part of the Wisconsin Pollutant Discharge Elimination System (WPDES).
The initial regional water quality management plan recommended that all of the
sanitary sewer service areas identified in the plan be refined and detailed in
cooperation with the local units of government concerned. There were two sewer
service areas identified within, or partially within, the Sauk Creek watershed,
Fort Washington, and Fredonia. Currently, these areas have undergone refine-
ments as recommended. The boundaries of the sewer service areas, as currently
refined, are shown on Map XIV-3. Table XIV-4 lists the plan amendment prepared
for each refinement and the date the Commission adopted the document as an
amendment to the regional water quality management plan. The table also identi-
fies the original service area names and the relationship of these service areas
to the service areas names following the refinement process. The planned sewer
