[Ord. No. 1548 §1, 12-4-2006]
During the construction process, soil is highly vulnerable to
erosion by wind and water. Eroded soil endangers the water resources
by reducing water quality and causing the siltation of the aquatic
habitat. Eroded soil also necessitates repair of sewers and ditches
and the dredging of lakes. In addition, clearing and grading during
construction cause the loss of native vegetation necessary for terrestrial
and aquatic habitat. As a result, local regulations are necessary
to safeguard persons, protect property and prevent damage to the environment
in the City of Oak Grove, Missouri.
[Ord. No. 1548 §1, 12-4-2006]
A. To
provide builders, developers and property owners with soil erosion
and sediment control standards and regulations. The regulations and
standards herein shall accomplish the following:
1. Establish standards for soil erosion and sediment control.
2. Minimize soil erosion and sedimentation during land development,
building, landscaping and other land disturbing activities.
3. Minimize pollution of streams, ponds and lakes.
4. Encourage management of natural resources.
5. Preserve the beauty of the community and the value of the land.
6. Reduce maintenance costs of public and private improvements and services.
7. Promote and protect the health, safety and welfare of the public.
8. Establish cash escrows to guarantee the performance and maintenance
of erosion and sediment control devices and measures.
9. Erosion and water runoff are inevitable, but their harmful effects
are not.
B. Land
management practices that pollute waterways or contribute to erosion
shall not be tolerated.
C. The
City does require that job sites and public streets be kept clean.
D. Buildings
shall be designed to fit the site rather than altering the site to
fit the building.
E. Every
effort shall be made to preserve mature trees.
F. Grading
and other land disturbing activities shall be minimized. Sites shall
be graded only where necessary to provide safe access and to accommodate
construction.
G. Enforcement
of this Chapter shall be administered by the City's Codes Enforcement
Department, the Public Works Department and the Police Department
based on their interpretation of these regulations.
[Ord. No. 1548 §1, 12-4-2006]
The following words, terms and phrases, when used in this Chapter,
shall have the meanings ascribed to them in this Section, except where
the context clearly indicates a different meaning:
BMP OR BEST MANAGEMENT PRACTICE
The preferred methods and products that will correct or control
erosion, sedimentation or water quality degradation on a specific
site for particular site conditions.
BUFFER
A small area of permanent vegetation bordering a field, stream
or lake, running through cropland, protecting the soil from wind and
water erosion, slowing water runoff and trapping sediment and other
pollutants.
CHANNEL
A natural stream or excavated ditch that conveys water.
CHANNEL STABILIZATION
Protection of the sides and bed of a channel from erosion
by controlling flow velocities and directions or by lining the channel
with vegetation, rip-rap, concrete or other material.
CITY
City of Oak Grove, Missouri.
CLEARING
Any activity that removes the vegetative surface cover.
CRITICAL AREAS
Regions highly susceptible to erosion such as areas subjected
to concentrated water flow.
DIVERSION
A channel and adjacent ridge or earth constructed to redirect
surface runoff water from one area to another for disposal at a non-erosive
velocity.
DRAINAGE WAY
Any channel that conveys surface runoff throughout the site.
EROSION
The wearing away of the land by the action of wind, water
or gravity.
EROSION AND SEDIMENT CONTROL PLAN
A set of plans prepared by or under the direction of a licensed
Professional Engineer. The plan indicates the specific measures and
sequencing to be used to control sediment and erosion on a development
site during and after construction.
EXCAVATION OR CUT
The removal, stripping or disturbance of soil, earth, sand,
rock, gravel or other similar substance from the ground.
EXISTING GRADE
The vertical location of the existing ground surface prior
to excavation or filling.
FILLING
The placing of any soil, earth, sand, rock, gravel or other
substance on the ground.
FINISHED GRADE
The final grade or elevation of the ground surface conforming
to the proposed design.
GRADING
Excavation or fill of material, including the resulting conditions
thereof.
LAND DISTURBING ACTIVITIES
Activities that destroy or remove the vegetation that covers
the soil at a construction site. These activities include clearing,
grubbing and grading.
MDNR
Missouri Department of Natural Resources.
NATURAL WATERCOURSE
A channel formed in the existing surface topography prior
to changes made by unnatural conditions.
OPEN CHANNEL
A constructed ditch or channel designed for water flow.
PERIMETER CONTROL
A barrier that prevents sediment from leaving a site by filtering
sediment-laden runoff or diverting it to a sediment trap or basin.
PHASING
Clearing a parcel of land in distinct phases, with the stabilization
of each phase completed before the clearing of the next phase.
SEDIMENT
Solid material, both mineral and organic, that is in suspension,
is being transported or has been moved by erosion and deposited in
a location other than the point of origin.
SEDIMENT BASIN
Depressions, formed from the construction of a barrier or
dam, created to retain runoff long enough to allow excess sediment
to settle out.
SITE
A parcel of land or a contiguous combination thereof, where
grading work is performed as a single unified operation.
SITE DEVELOPMENT PERMIT
A permit issued by the City for the construction or alteration
of ground. Improvement and structures for the control or erosion,
runoff and grading should be included with the permit.
STABILIZATION
The use of practices that prevent exposed soil from eroding.
START OF CONSTRUCTION
The first land-disturbing activity associated with a development,
including land preparation such as clearing, grading and filling;
installation of streets and walkways; excavation for basements, footings,
piers or foundations; erection of temporary forms; and installation
of accessory buildings such as garages.
STREAMBANK
The top of the natural incline bordering a stream.
TOPSOIL
Surface soil usually containing organic matter; the soil
most capable of growing vegetation and crops.
VEGETATION
Plant life or total plant cover of an area.
WATER QUALITY
The chemical, physical and biological characteristics of
water, usually with respect to its suitability for a particular purpose.
WATERCOURSE
Any body of water, including, but not limited to lakes, ponds,
rivers, streams and bodies of water delineated by the City of Oak
Grove, Missouri.
WATERWAY
A channel that directs surface runoff to a watercourse or
to the public storm drain.

person, firm or corporation may excavate, grade, develop or disturb
land until an Erosion and Sediment Control Plan has been submitted
and approved and a land disturbance or building permit has been issued.
B. If
any conflict arises with these or other City, State and Federal regulations,
the more restrictive provisions shall govern.
