[Ord. No. 1100 §I, 3-20-2006]
A.
During
the construction process, soil is highly vulnerable to erosion by
wind and water. Eroded soil endangers water resources by reducing
water quality and causing the siltation of aquatic habitat for fish
and other desirable species. Deposits of eroded soil also necessitates
maintenance 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. Construction
activities also utilize materials and generate wastes which, if not
properly controlled, can pollute receiving waters.
B.
The
purpose of this Chapter is to safeguard persons, protect property
and prevent damage to the environment in the City of Breckenridge
Hills. This Chapter will also promote the public welfare by guiding,
regulating and controlling the design, construction, use and maintenance
of any development or other activity that disturbs or breaks the topsoil
or results in the movement of earth on land in the City of Breckenridge
Hills.

any of the provisions of this Chapter shall be required to bear the
expense of such restoration.
C.
Project Closure Requirements. Any site development escrows
or bonds will be not be fully released to the site operator or permittee
until all of the following have been completed:
A.
Purpose. The purpose of this guidance manual is to provide
direction to municipal officials and staff for implementing the provisions
of municipal ordinances pertaining to regulation of land disturbance
activities and related stormwater controls. This guidance will help
promote efficient plan reviews and processing of permit applications
so as to benefit the community and to ensure compliance with the terms
of the City of Breckenridge Hills State issued MS4 NPDES permit. Certain
requirements of Section 4.2.4 of the MS4 permit, as referenced below,
are addressed within this guidance manual.
B.
General Provisions. The Department of Public Works shall
be responsible for enforcing the provisions of the Grading, Erosion
and Sediment Control Ordinance No. 1100. The Department of Public
Works shall review all permit applications submitted pursuant to that
ordinance and shall issue permits with such conditions as deemed appropriate
to enable compliance with the grading ordinance and other related
ordinances. The Department shall conduct all required inspections
of permitted sites and shall be responsible for initiating enforcement
actions when violations are identified.
Persons who intend to disturb land within Breckenridge Hills
will be reminded, at the time of initial contact with municipal officials,
of the need to obtain a separate land disturbance permit from the
Missouri Department of Natural Resources for any construction or land
disturbance activity that will result in disturbance of one (1) acre
or more of land. Persons intending to disturb such acreage must be
informed that site work may not commence until the State permit has
been obtained. Any municipal permit, for sites one (1) acre or above,
will also contain this requirement as a permit condition.
C.
Water Quality Considerations (See Section 4.2.4.2.4 Of The MS4 Permit). During review of site plans, Storm Water Pollution Prevention Plans
(SWPPP) and other documents submitted as part of the permit application,
Department staff shall consider the potential water quality impacts
of the project both during the construction/land disturbance phase
and after site development is fully complete. Department staff should
consider the provisions within the Missouri Water Quality Standards,
the Missouri Impaired Waters list (303(d) list), the Federal Endangered
Species Act, the National Historic Preservation Act and proximity
to water bodies identified by MDNR as "Valuable Resource Waters" (see
attached listing). To the maximum extent practicable under State and
local laws, the Department shall include such conditions in permits
as are appropriate to prevent or minimize impacts on water quality.
Department staff shall solicit comments or advice, when deemed appropriate,
from the Missouri Department of Natural Resources, the Missouri Department
of Conservation, the Soil and Water Conservation District and such
other State and national regulatory bodies as may have expertise related
to a specific project or area.
D.
Public Inquiries/Complaints (See Section 4.2.4.2.5 Of The MS4 Permit). The Department of Public Works shall maintain a system for recording
and tracking inquiries and complaints received from the public regarding
proposed and active land disturbance sites within Breckenridge Hills.
The following information shall be logged, on a standard form, for
each inquiry/complaint:
1.
Date;
2.
Name, address and telephone number of the inquiring/complaining party;
3.
Nature of inquiry/complaint, including all pertinent information
related thereto; and
4.
Follow up action. If an inspection is performed,
all information regarding the date and time, inspector's name, findings
and any mitigation or enforcement actions initiated shall be recorded.
|
|
All inquiries or complaints must be logged. However, it is up
to the sole discretion of the Department of Public Works, with such
consultation with other departments or agencies as may be deemed appropriate,
as to whether any follow up action is deemed appropriate. If no follow
up action is deemed necessary, a short explanation shall be recorded
on the standard inquiry form.
|
E.
Inspections/Reports (See Section 4.2.4.2.6 Of The MS4 Permit). The Department of Public Works shall inspect each permitted site
at the frequency as necessary to insure compliance with this Chapter
and to follow up on public inquiries/complaints or to follow up on
previously identified deficiencies. The results of all inspections
shall be recorded in written reports and maintained in the project
file. Inspections shall be carried out in such a way as to determine
whether the site operator is complying with all provisions of the
City of Breckenridge Hills permit.
Department staff shall ensure receipt of all site operator notifications
and site operator self- inspections as required by the permit. Staff
shall take such follow up actions as may be deemed necessary based
on the content of received notifications and reports.
F.
Transfer Of Ownership — Individual Lot Or Lots. City
of Breckenridge Hills ordinances require a permit, as well as controls
for sediment, erosion and other construction site pollutants for disturbed
areas of land in excess of twelve thousand (12,000) square feet disturbed
as part of a common plan or sale. That language means the lot(s) when
sold to an entity for construction (unless sold to an individual for
purposes of building their own private residence) are also subject
to ordinance requirements because they are part of the common sale.
A current permittee who intends to transfer ownership of a lot or
parcel of the overall permitted area is still responsible for the
terms of the Breckenridge Hills permit and the SWPPP and erosion control
on that site unless the new owner applies for and receives a separate
permit for land disturbance activities. If the current permittee is
to retain the permit and responsibility for control of sediment and
other pollutants at the site, then the owner should obtain a copy
of an Individual Lot Certification (ILC) from the lot owner(s). The
ILC should be properly completed and signed and retained with the
SWPPP.
Entire tract. If the entire tract is sold to
a single entity, then the Breckenridge Hills permit shall be terminated
and the new owner shall submit an application for a new permit immediately.
G.
Reference Sources. The staff will provide every permit applicant
with the following list of reference and guidance documents which
may be employed in development of the SWPPP. For activities requiring
State land disturbance permits, the first two (2) documents listed
are considered mandatory references for all applicants.
