The purpose of this article is to provide a set of minimum
standards for the maintenance of environmental conditions necessary
for insuring the general health, safety, and well-being of the community.
No rezoning shall be permitted that will result
in the serious deterioration of environmental resources. Therefore,
a zoning petition shall be prepared to demonstrate to the Commission
how the anticipated development may be accomplished, so as to prevent
environmental deterioration. The following portions of this article
will be devoted to the development of minimum standards for the protection
of the environment.
Any construction, development, or use of land
in any zone shall be subject to the additional standards contained
in this article. To adequately satisfy themselves, that these standards
can be met, the Commission may require the following information from
a zoning petitioner prior to taking action on his petition.
General soil maps, interpretative text of soil
uses, general slope maps, percolation tests, test well logs, and any
other reasonable information the Commission deems necessary to determine
the suitability of the site for the uses anticipated, and to show
the susceptibility of natural features to erosion and pollution problems.
A general site layout showing how the site can
be developed without resulting in conditions which are in conflict
with the standards of this article.
Specifications and descriptions of any waste
treatment system, not part of the Village of Harristown treatment
system.
(A)
General standards for the prevention of erosion. No
development shall be permitted which would result in a major transfer
of topsoil to areas of streams, drainage systems, roadways, or other
lands by erosion. The Commission shall consider the erosion susceptibility
of the site, and the proposals of the developer to contain erosion
where erosion possibilities are suspected, prior to rezoning a parcel
of ground.
(A)
Purpose. The regulations contained in this article,
governing the development and use of land subject to flooding, are
established for the following purposes:
(1)
To avoid or lessen the hazards to persons, or
damage to property resulting from the accumulation or runoff of storm-
and floodwaters;
(2)
To protect the stream channels from encroachment;
(3)
To maintain the capacity of the floodplain to
retain floodwaters;
(4)
To provide for the development of floodplain
lands with uses not subject to severe damage by flooding and compatible
with the other uses permitted in the various zones;
(5)
To permit only uses and improvements on floodplain
lands that are not hazardous during flood periods;
(6)
To avoid the creation of new flood problems;
(7)
To prevent the filling of any stream channel
or the raising of any floodplain without a written special permit
from the Village of Harristown.

Definitions. For the purpose of this article and this
Code generally the following terms shall have these meanings:
The elevation of the one-hundred-year flood (the Intermediate
Regional Flood) as shown in Floodplain Information-Macon County, IL
prepared by the United States Army Corps of Engineers, February 1971,
or in the absence of such record those levels established by the Village
Engineer.
The continuous land area adjacent to the floodplain, the
elevation of which is greater than the flood base elevation by two
feet or less.
The continuous area adjacent to a lake, stream, or stream
bed the elevation of which is greater than the normal water level
or pool elevation, but equal to or lower than the flood base elevation;
also, any land of higher elevation, having an area less than the minimum
residential lot size established for the zone in which it is located
and surrounded by lands having an elevation equal to or less than
the flood base elevation.
A stream is any continuously flowing natural watercourse.
(C)
Building in floodplain areas. No building or structure
shall be erected with the elevation of a habitable floor, including
a basement floor, lower than two feet above the floodplain elevation.
All lands determined to be in the floodplain shall be subject to the
procedures and regulations established in this Section. However, nothing
contained herein shall prohibit the application of these regulations
to lands which can be demonstrated by competent engineering survey
to lie within any floodplain. Conversely, any lands which can be demonstrated
by a competent engineering survey to lie beyond the floodplain shall
not be subject to these regulations. All other structures which are
permitted to be constructed on the floodplain must be so constructed
that they will not be damaged by flood and will not represent a hazard
at the time of flooding.
