[Ord. No. 14-04-09 §1, 4-21-2014]
A.
Grading,
erosion control practices, sediment control practices, and waterway
crossings shall be adequate to prevent transportation of sediment
and other pollutants from the site.
B.
For sites that disturb less than one (1) acre unless otherwise exempted under Section 407.030, the owner/developer/contractor must provide a sketch plot plan indicating the overall layout of buildings and other impervious areas, indicate flow direction with arrows and show the location of construction site best management practices. This plan does not necessarily need to be prepared by a registered professional engineer.
C.
For
sites that disturb greater than one (1) acre, the owner/developer
shall provide a Stormwater Pollution Prevention Plan (SWPPP) and associated
drawings prepared by a registered professional engineer. The design
and construction guidance in KC-APWA 5100 shall be followed insofar
as it is applicable. Additional guidance for construction site runoff
control can be found in MDNR's "Protecting Water Quality Field Guide".
Stormwater Pollution Prevention Plans must meet MDNR's requirements
set forth in the General Operating Permit for Construction or Land
Disturbance Activity.
D.
All
construction shall meet the criteria set forth below insofar as they
are applicable as determined by the Director.
[Ord. No. 14-04-09 §1, 4-21-2014]
A.
Clearing
and grading of natural resources, such as forests and wetlands, shall
not be permitted, except when in compliance with all other City regulations.
B.
Clearing
techniques that retain natural vegetation and retain natural drainage
patterns shall be used to the maximum extent practicable.
C.
Clearing,
except that necessary to establish sediment control devices, shall
not begin until all sediment control devices have been installed and
have been stabilized.
D.
Cut
and fill slopes shall be no greater than 2:1, except as approved by
the City to meet other community or environmental objectives.
E.
Phasing
shall be required on all sites disturbing greater than thirty acres,
with the size of each phase to be established at plan review.
F.
Other
measures may be required in order to ensure that sediment is not tracked
onto public streets by construction vehicles, or washed into storm
drains.
[Ord. No. 14-04-09 §1, 4-21-2014]
A.
Soil
must be stabilized within fourteen (14) days of clearing or inactivity
in construction, unless otherwise authorized, and shall be effectively
maintained throughout the duration of any inactivity.
B.
Soil
stockpiles must be stabilized or covered at the end of each work day
unless otherwise protected from allowing sediment to leave the site.
C.
Techniques
shall be employed to prevent the blowing of dust or sediment from
the site.
D.
Techniques
that divert upland runoff past disturbed slopes shall be employed.
[Ord. No. 14-04-09 §1, 4-21-2014]
A.
Sediment
controls shall be provided in the form of settling basins or sediment
traps or tanks, and perimeter controls.
B.
Where
possible, settling basins shall be designed in a manner that allows
adaptation to provide long term stormwater management.
C.
Adjacent
properties shall be protected by the use of a vegetated buffer strip,
in combination with perimeter controls wherever possible.
[Ord. No. 14-04-09 §1, 4-21-2014]
A.
When
a wet watercourse must be crossed regularly during construction, a
temporary stream crossing shall be provided, and an approval obtained
from the U.S. Army Corps of Engineers and the Missouri Department
of Natural Resources if deemed a jurisdictional stream.
B.
When
in-channel work is conducted, the channel shall be stabilized before,
during and after work.
C.
Stabilization
adequate to prevent erosion must be provided at the outlets of all
pipes and paved channels.
[Ord. No. 14-04-09 §1, 4-21-2014]
A.
A temporary
access road or driveway shall be provided at all sites.
B.
Regardless
of the amount of land disturbance at a particular site, it shall be
the responsibility of the permit holder and/or property owner to ensure
streets open to the public surrounding a permitted site are kept free
of debris and sediment throughout construction. Upon notification
that a problem exists, the permit holder and/or property owner shall
remedy the issue within 24 hours.
[Ord. No. 14-04-09 §1, 4-21-2014]
A.
Concrete Truck Washout. Concrete truck washout shall not
discharge surplus concrete or drum wash water on the site in such
a manner that promotes contact with storm waters discharging from
the site.
B.
Construction Waste. All construction waste material shall
be collected, deposited, and stored in a manner to prevent contact
with storm waters discharging from the site and shall be disposed
of by a licensed solid waste management contractor. No waste shall
be buried on the site.
C.
Sanitary Waste. A licensed sanitary waste management contractor
shall collect all sanitary waste from portable units that will be
maintained on a regular basis for any site that cannot provide other
means of sanitary waste disposal.
D.
Petroleum Products. All construction equipment and vehicles
shall be monitored for leaks and receive regular preventative maintenance
to ensure proper operation and reduce the risk for leaks or spills.
Petroleum products shall be stored in clearly labeled and tightly
sealed containers or tanks. Any soil contaminated by fuel or oil spills
shall be removed and disposed of properly.
E.
Fertilizers. Fertilizers shall be applied following manufacturer's
recommendations. Fertilizers shall be stored in a covered area or
in watertight containers. Partially used products shall be properly
sealed and stored to avoid spills or leaks.
F.
Hazardous Materials. Storage areas for hazardous materials
such as oils, greases, paints, fuels, and chemicals, shall be provided
with secondary containment to ensure that spills in these areas do
not reach waters of the State. All hazardous waste materials shall
be disposed of according to state regulation or the manufacturer's
recommendations.
