[Ord. No. 17-0244, 4-24-2017]
A. Without inspection and maintenance of siltation/erosion control measures,
erosion and siltation control measures will not remain effective for
long periods of time. Without proper training of inspection staff
and effective records of results of inspections, it is difficult to
determine what maintenance is required.
B. The Inspector Needs To Fully Understand The SWPPP. The SWPPP is more
than just words and symbols on a piece of paper; it is a blueprint
for contractors to follow. The inspector must know the implementation
schedules, know where and when BMPs are to be installed, know what
BMPs are to be maintained or eliminated and fully understand the limitations
of BMPs.
C. The contractor needs to be informed by their inspector or an independent
inspector, if used, of any non-compliance or violation issues. It
is recommended that the inspector meet at least weekly with the contractor(s)
to avoid problems that might lead to non-compliance issues. Also,
the inspector must be cognizant of his/her responsibilities relative
to identifying where modifications to the SWPPP are needed and recognize
when it is necessary to involve owners, designers and regulatory personnel
in modifications to the SWPPP or concerns about the operation of the
SWPPP. Open and regular communication with all companies and agencies
is essential.
D. The inspector also needs to be aware of appropriate contacts regarding
maintenance of BMPs or other concerns. At some points of the project,
the developer's land development personnel may be the sole contact,
at other stages of construction, it may be necessary to communicate
with personnel responsible for building construction.
E. General inspection guidelines follow to provide some additional guidance
to the inspector. These guidelines are provided as a tool for the
inspector's use and do not attempt to address all items that can be
included on a specific SWPPP. The importance of reporting the results
of inspections and follow up with appropriate personnel cannot be
stressed enough.
[Ord. No. 17-0244, 4-24-2017]
A. The inspector is responsible for:
1.
Inspecting the site to ensure proper installation, operation
and maintenance of BMPs;

1.
The location and type of control measures;
2.
The construction requirements for the control measures;
3.
Spill prevention and cleanup measures; and
4.
Inspection and maintenance record keeping requirements.
C. The inspector should determine the following from the inspection:
1.
The effectiveness of each BMP;
2.
The maintenance that needs to be performed on the BMP; and
3.
The need for revisions to the SWPPP.
D. General items to inspect:
1.
BMPs installed in timely fashion;
2.
BMPs installed/performing correctly;
4.
Has maintenance been performed;
5.
Is the BMP still effective;
7.
Note areas where grading activities have started/stopped;
8.
Areas stabilized within fourteen (14) days of work being halted;
9.
Removal of BMPs that are no longer required; and
10.
Evaluate need for revision to SWPPP.
E. Areas To Inspect:
2.
All recently stabilized areas;
3.
All locations where an erosion/silt control device is installed;
4.
Off-site areas/outfall points including adjacent roadways;
5.
Operational storm sewer inlets;
8.
Concrete washout areas; and
9.
Temporary toilets on site.

(B) below;
2. The Planning and Zoning Commission ("Commission") shall have the power to vary or modify the standards contained in this Chapter, with the exception of standards outlined in Section
505.950(A)(1) detailed in accordance with exceptional conditions stated in Subsection
(B) below.
B. To be granted a variance, an applicant must show the following:
1.
The variance requested arises from a condition which is unique
and peculiar to the property in question and is not created by an
action or actions of the property owner or applicant.
2.
Where, by reason of exceptional narrowness, shallowness, shape
or topography or other extraordinary or exceptional situation or condition
of a specific piece of property, the strict application of the provisions
of the regulations complained of will constitute peculiar and exceptional
difficulties to or exceptional and demonstrable undue hardship upon
the owner of the property, as an unreasonable deprivation of use as
distinguished from the mere grant of a privilege.
3.
The variance requested will not cause substantial detriment
to the public health, safety, morals and general welfare of the community
nor will it cause damage to other property in the area.
4.
The granting of the variance will not substantially impair the
intent, purpose and integrity of the zone plan as embodied in the
UDO.
C. In granting a variance, the Commission or Director:
1.
May impose such conditions, safeguards and restrictions or require
improvements upon the premises benefited by the variance as may be
necessary to reduce or minimize any potentially injurious effect of
the variance upon other property in the neighborhood and to carry
out the general purpose and intent of these regulations.
2.
Shall require the variance, where appropriate, to be recorded
with the County Recorder of Deeds by the Planning Division and any
costs of recording be paid by the applicant to be effective.
3.
May require the applicant to guarantee the installation of required
improvements. The guarantee shall be secured by an instrument acceptable
to the County in an amount that shall be based on a general estimate
of cost for the required improvements as determined by the Director
and shall be enforceable by or payable to the County in the sum equal
to the cost of constructing the required improvements. In place of
a security instrument, the Board may set the effective date for the
variance as subsequent to completion of the conditions, safeguards
and restrictions.
4.
In lieu of the secured guarantee or delayed effective date,
the Commission or Public Works Director may specify a time limit for
completion of the required improvements and in the event the improvements
are not completed within the specified time, the Commission may, at
a regularly scheduled meeting and after notice to applicant, revoke
the approval of the variance.
5.
Shall issue an order stating the findings of fact and conclusions
of law for reaching the decision.
