diameter. If larger than eight-inch-diameter sanitary sewers are required
to handle the contemplated sewage flows, the costs of such larger
sewers shall be prorated in proportion to the ratio which the total
sewage of the proposed subdivision, certified survey map, or condominium
is to the total sewage capacity to be served by such larger sewer,
and the excess cost shall be either borne by the Town of Barton or
assessed against the total tributary sewer area.
E.
Sanitary sewer availability and requirements for installation. The
subdivider or condominium developer (as applicable) shall install
sanitary sewers in accordance with this chapter and specifications
of the Town, including the Town's "Standards and Specifications for

(as applicable) to construct either individual or common wastewater
holding facilities sufficiently sized and placed to accommodate the
subdivision, certified survey map, or condominium. Said wastewater
holding tanks shall be constructed pursuant to Chapter 25, titled
"Sanitary Code," of the Washington County Code, as amended, and in
such a manner so as to make available wastewater holding facilities
to each lot of the land division.
The subdivider or condominium developer (as applicable) shall
construct stormwater drainage facilities adequate to serve the subdivision,
certified survey map, or condominium in conformance (as applicable)
with the adopted county development plan or elements thereof; all
applicable Washington County codes pertaining to stormwater management;

required by the Town of Barton based upon recommendation of the Town
Engineer. These facilities may include curbs and gutters, catch basins
and inlets, storm sewers, road ditches, open channels, water retention
and detention structures, basins, and settling basins. All such facilities
shall be of adequate size and grade to hydraulically accommodate the
maximum potential volumes of flow and shall be so designed as to prevent
and control soil erosion and sedimentation and to present no hazards
to life or property. In addition:

except for the added cost of installing storm sewers greater than
those which are necessary to serve tributary drainage areas lying
outside of the proposed subdivision, certified survey map, or condominium.
(2)
The cost of such larger storm sewers shall be prorated in proportion
to the ratio which the total area of the proposed subdivision, certified
survey map, or condominium is to the total drainage area to be served
by such larger sewer, and the excess cost shall either be borne by
the Town of Barton or assessed against the total tributary drainage
area.
A.
Adequate water supply facilities to be made available. When public
water supply and distribution facilities are available to the subdivision
