SECTION 101.0 SCOPE
| |||
101.1 Title: These regulations shall be known
as the "Land Disturbance Code" of St. Louis County, Missouri, hereinafter
referred to as "this code".
| |||
101.2 Introduction: On construction or land
disturbance sites, 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 necessitate 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.
| |||
101.3 Purpose: The purpose of this code is
to safeguard persons, protect property and prevent damage to the environment
in St. Louis County. This code 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 St. Louis County.
| |||
101.4 Scope: This code provides for the safety,
health and welfare of the public by regulating and controlling the
design, construction, use and maintenance of any development or other
activity that disturbs land surfaces or results in the movement of

notification shall be subject to the penalties enumerated in Sections
104.4 and 104.4 and 104.4.1.
| |||
104.2.1 Notice of Violations on Highways and Traffic
Projects: The notice of violation will consist of the site
Storm Water Pollution Prevention Plan (SWPPP) construction site inspection
report delivered to the contractor by the resident engineer or their
assign. Any person having been notified that a violation exists and
who fails to abate the violation within seven calendar days after

the provisions of this code or shall start any work requiring a permit
without first obtaining a permit therefore, or who shall continue
any work in or about a structure after having been served a stop work
order, except for such work which that person, firm or corporation
has been directed to perform to remove a violation or unsafe conditions,
or any owner of a property or any other person who commits, takes
part or assists in any violation of this code or who maintains any
property on which such violation shall exist shall be guilty of a
misdemeanor punishable by a fine of not more than $1,000.00 or by

| |||
104.4.1 Contractor Non-compliance on County Projects: The County may choose, at its option, to use County forces or hire
a contractor or use other methods to correct the land disturbance
violation after seven calendar days or less from the notice of violation
date, if the Missouri Clean Water Act may possibly be violated. Weather-related
non-compliance might be tolerable. The County may deduct that amount
incurred to correct the land disturbance violation from the contract
obligation.
| |||
104.4.2 No-Permit Penalty: In addition to the
penalties set out above, the following procedure shall be followed
where a County department identified in Section 103 determines that
work has been started prior to the acquisition of a permit required
by this code:
| |||
1.
|
The department shall issue a stop work order.
| ||
2.
|
The department Director shall notify the violator of his/her
assessment regarding the appropriate penalty amount to be assessed
against the violator, which shall not exceed one thousand dollars
($1,000.00) for each day that work occurs without a permit. In making
the assessment, the department shall consider whether the violator
has previously violated this code and whether the occupation or experience
of the violator indicates that he/she knew or should have known that
a permit was required. In no case will a no-permit penalty be assessed
against a property owner unless he/she actually performed the work
involved.
| ||
3.
|
At the violator's option, he/she may deposit the assessed penalty
amount in escrow (certified check or cash only) with the department,
in which case the violator's right to a hearing will be preserved.
| ||
4.
|
No-permit penalties are appealable to the Building Commission
in the same manner as other decisions of the department. The department
may revise its assessment upon notice to both the Building Commission
and the violator at any time prior to the hearing. Likewise, at any
time prior to the hearing, the violator may accept and pay the recommended
penalty amount and the hearing will be canceled.
| ||
5.
|
At the hearing before the Building Commission, said Commission
shall afford both the department and the alleged violator an opportunity
to present any evidence or make any statements they wish to have considered.
| ||
6.
|
Following the hearing the Building Commission shall determine
whether a permit was required:
| ||
a.
|
If the Building Commission determines that a permit was required,
an appropriate penalty amount shall be assessed, taking into account
the same considerations as noted above. The stop work order shall
remain in full force and effect until such time as the penalty amount
is paid and the violator has complied with all other regulations pertaining
to the issuance of permits.
| ||
b.
|
If the Building Commission determines that no permit was required,
the department shall immediately cancel the stop work order.
| ||
104.5 Abatement of Violation: The imposition
of the penalties herein prescribed shall not preclude the County Counselor
from instituting appropriate action to prevent unlawful construction
or to restrain, correct or abate a violation, or to prevent illegal
use of a property or to stop an illegal act.
| |||
104.6 Permit Suspension or Revocation: When
a land disturbance activity is conducted in violation of the requirements
of this code or the terms of the permit in such a manner as to materially
adversely affect the safety, health or welfare of persons or materially
be detrimental or injurious to property or improvements, the Department
of Public Works or the Department of Highways and Traffic may suspend
or revoke such permit.

be given to the owner of the property involved or to the owner's agent
or to the person doing the work and shall state the conditions under
which work will be permitted to resume. Any person who shall continue
any work in or about the property after having been served with a
stop work order, except such work as that person is directed to perform
