[Ord. No. 2974 §1(Art. 16 §251), 11-2-2004]
A. In any area that is located outside a designated floodplain but where
a stream is located to the extent possible, no building or fill may
be located within a distance of the stream bank equal to five (5)
times the width of the stream at the top of the bank or twenty (20)
feet on each side, whichever is greater.
B. Use Franklin or Crawford County Soil Survey detailed field sheets,
map unit descriptions and soil and water feature table to assist with
on-site evaluations.
[Ord. No. 2974 §1(Art. 16 §252), 11-2-2004]
All activities or uses in floodway or floodplains will be governed by the provisions contained in Chapter
405 of this Code.
[Ord. No. 2974 §1(Art. 16 §261), 11-2-2004]
A. To the extent practicable, all development shall conform to the natural
contours of the land and natural and pre-existing manmade drainage
ways shall remain undisturbed.
B. To the extent practicable, lot boundaries shall be made to coincide
with natural and pre-existing manmade drainage ways within subdivisions
to avoid the creation of lots that can be built upon only by altering
such drainage ways.
[Ord. No. 2974 §1(Art. 16 §262), 11-2-2004]
A. All developments shall be provided with a drainage system that is
adequate to prevent the undue retention of surface water on the development
site. Surface water shall not be regarded as unduly retained if:
1.
The retention results from a technique, practice or device deliberately
installed as part of an approved sedimentation or stormwater runoff
control plan; or
2.
The retention is not substantially different in location or
degree than that experienced by the development site in its predevelopment
stage, unless such retention presents a danger to health or safety.
B. No surface water may be channeled or directed into a sanitary sewer.
C. Whenever practicable, the drainage system of a development shall
coordinate with and connect to the drainage systems or drainage ways
on surrounding properties or streets.
D. Use of drainage swales rather than curb and gutter and storm sewers
in subdivisions may be used when approved by the Engineering Department
and in accordance with department specifications. Private roads and
access ways within unsubdivided developments shall utilize curb and
gutter and stone drains to provide adequate drainage if the grade
of such roads or access ways is too steep to provide drainage in another
manner or if other sufficient reasons exist to require such construction.
E. Construction specifications for drainage swales, curbs and gutters
and storm drains are contained in Appendix C to this Chapter.
[Ord. No. 2974 §1(Art. 16 §263), 11-2-2004]
A. All developments shall be constructed and maintained so that adjacent
properties are not unreasonably burdened with surface waters as a
result of such developments. More specifically:
1.
No development may be constructed or maintained so that such
development unreasonably impedes the natural flow of water from higher
adjacent properties across such development, thereby unreasonably
causing substantial damage to such higher adjacent properties; and
2.
No development may be constructed or maintained so that surface
waters from such development are unreasonably collected and channeled
onto lower adjacent properties at such locations or at such volumes
as to cause substantial damage to such lower adjacent properties.
[Ord. No. 2974 §1(Art. 16 §264), 11-2-2004]
A. No zoning or conditional use permit may be issued and final plat
approval for subdivisions may not be given with respect to any development
that would cause land disturbing activity subject to the jurisdiction
of the Missouri Department of Natural Resources unless it has certified
to the City, either that:
1.
An erosion control plan has been submitted to and approved by
Missouri Department of Natural Resources; or
2.
The Missouri Department of Natural Resources has examined the
preliminary plans for the development and it reasonably appears that
an erosion control plan can be approved upon submission by the developer
of more detailed construction or design drawings. However, in this
case, construction of the development may not begin (and no building
permits may be issued) until the Missouri Department of Natural Resources
approves the erosion control plan.
B. For purposes of this Section, "land disturbing activity" means any use of the land by any person in residential, industrial,
educational, institutional or commercial development and highway and
road construction and maintenance that results in a change in the
natural cover or topography and that may cause or contribute to sedimentation.
Sedimentation occurs whenever solid particulate matter, mineral or
organic, is transported by water, air, gravity or ice from the site
of its origin.
[Ord. No. 2974 §1(Art. 16 §265), 11-2-2004]
Developers shall be required to obtain all permits, including
four hundred four (404) permits, for all work to be performed in or
adjacent to waters of the United States. Written proof shall be supplied
with permit applications.
