[Zoning Regs. §19.060; Ord. No. 1014 §3, 6-12-1998]
A. Grading Permits Required. No person shall do any grading without first obtaining a grading permit from the zoning enforcement person after following the procedures set forth in Section
405.630. A separate permit shall be required for each site.
B. Grading Definition. "Grading" is defined
to be the change in elevation of twelve (12) inches or more within
one (1) calendar year. Except that within the floodway or floodway
fringe areas, any change in elevation which costs in excess of five
hundred dollars ($500.00) shall require a grading permit.
C. Fees. The fee for said permit shall be two percent (2%)
of estimated cost.
D. Bond. Every applicant shall be required to state the location
of the fill material being used to fill the excavated site. If the
location of the fill material requires the applicant to haul the fill
material over the City streets of Platte City, Missouri, then the
applicant shall post a bond to cover any damages to the City streets
as a result of the hauling process. The amount of the bond shall be
determined at the discretion of the Board of Aldermen.
E. Fills.
1. General. Unless otherwise recommended in the approved
soils engineering report, fills shall conform to the provisions of
this Section. In the absence of an approved soils engineering report,
these provisions may be waived for minor fills not intended to support
structures.
2. Fill location. Fill slopes shall not be constructed
on natural slopes steeper than two (2) to one (1).
3. Preparation of ground. The ground surface shall
be prepared to receive fill by removing vegetation, non-complying
fill, topsoil and other unsuitable materials scarifying to provide
a bond with the new fill and, where slopes are steeper than five (5)
to one (1) and the height is greater than five (5) feet, by benching
into sound bedrock or other competent material as determined by the
soils engineer. The bench under the toe of a fill on a slope steeper
than five (5) to one (1) shall be at least ten (10) feet wide. The
area beyond the toe of fill shall be sloped for sheet overflow or
a paved drain shall be provided. When fill is to be placed over a
cut, the bench under the toe of fill shall be at least ten (10) feet
wide but the cut shall be made before placing the fill and acceptance
by the soils engineer or engineering geologist or both as a suitable
foundation for fill.
4. Fill material. Detrimental amount of organic material
shall not be permitted in fills. Except as permitted by the Building
Official, no rock or similar irreducible material with a maximum dimension
greater than twenty-four (24) inches shall be buried or placed in
fills.
Exception: The Building Official may permit
placement of larger rock when the soils engineer properly devises
a method of placement, continuously inspects its placement and approves
the fill stability. The following conditions shall also apply:
a. Prior to issuance of the grading permit, potential rock disposal
areas shall be delineated on the grading plan.
b. Rock sizes greater than twenty-four (24) inches in maximum dimension
shall be four (4) feet or more below proposed finished grade, measured
vertically.
c. Rocks shall be placed so as to assure filling of all voids with fines.
5. Compaction. All fills shall be compacted to a minimum
of ninety percent (90%) of maximum density as determined by U.B.C.
Standard No. 70-1. In-place density shall be determined in accordance
with U.B.C. Standard 70-2, 70-3, 70-4 or 70-5.
6. Slope. The slope of fill surfaces shall be no steeper
than is safe for the intended use. Fill slopes shall be no steeper
than three (3) horizontal to one (1) vertical.
7. Drainage and terracing. Drainage and terracing shall
be provided and the area above fill slopes and the surfaces of terraces
shall be graded and paved as required by applicable Building Codes.
F. Steep slopes (topography having an incline in excess of fifteen percent (15%)) will not normally be permitted to be used for development. However, on review, the Planning Commission may permit limited development if a conditional use permit is obtained by the proper procedures set forth in Article
XXII.
[Zoning Regs. §19.070; Ord. No. 1014 §3, 6-12-1998]
All grading and filling must be completed within one hundred
eighty (180) days of the date of the issuance of the grading permit.
[Zoning Regs. §19.080; Ord. No. 1014 §3, 6-12-1998]
When required by the zoning enforcement person, each application
for a grading permit shall be accompanied by two (2) sets of plans
and specifications and supporting data consisting of a soils engineering
report and engineering geology report. The plans and specifications
shall be prepared and signed by a civil engineer when required by
the zoning enforcement person.
[Zoning Regs. §19.090; Ord. No. 1014 §3, 6-12-1998]
A. Plans
shall be drawn to scale upon substantial paper or cloth and shall
be of sufficient clarity to indicate the nature and extent of the
work proposed and show in detail that they will conform to the provisions
of this Code and all relevant laws, ordinances, rules and regulations.
The first (1st) sheet of each set of plans shall give the location
of the work and the name and address of the owner and the person by
whom they were prepared. The plans shall include the following information:
1. General vicinity of the proposed site.
2. Property limits and accurate contours of existing ground and details
of terrain and area drainage.
3. Limiting dimensions, elevations or finish contours to be achieved
by the grading and proposed drainage channels and related construction.
4. Detailed plans of all surface and subsurface drainage devices, walls,
cribbing, dams and other protective devices to be constructed with,
or as a part of, the proposed work together with a map showing the
drainage area and the estimated runoff of the area served by any drains.
5. Location of any buildings or structures on the property where the
work is to be performed and the location of any buildings or structures
on land of adjacent owners which are within fifteen (15) feet of the
property or which may be affected by the proposed grading operations.
6. Specifications shall contain information covering construction and
materials requirements.
[Zoning Regs. §19.100; Ord. No. 1014 §3, 6-12-1998]
A. The soils engineering report required by Section
405.650 shall include data regarding the nature, distribution and strength of existing soils, conclusions and recommendations for grading procedures and design criteria for corrective measures, including buttress fills, when necessary, and opinions and recommendations covering adequacy of sites to be developed by the proposed grading, including the stability of slopes.
B. Recommendations
included in the report and approved by the zoning enforcement person
shall be incorporated in the grading plans or specifications.
[Zoning Regs. §19.110; Ord. No. 1014 §3, 6-12-1998]
A. The engineering geology report required by Section
405.650 shall include an adequate description of the geology of the site, conclusions and recommendations regarding the effect of geologic conditions on the proposed development and opinions and recommendations covering the adequacy of sites to be developed by the proposed grading.
B. Recommendations
included in the report and approved by the zoning enforcement person
shall be incorporated in the grading plans or specifications.
[Zoning Regs. §19.120; Ord. No. 1014 §3, 6-12-1998]
The zoning enforcement person may require that grading operations
and project designs be modified if delays occur which incur weather-generated
problems not considered at the time the permit was issued.
[Zoning Regs. §19.125; Ord. No. 1014 §3, 6-12-1998; Ord. No. 1454 §10(19.125), 1-11-2006]
Any persons commencing work before permit issuance on a building,
structure, plumbing, electrical, gas, mechanical systems or grading
work before obtaining the necessary permits shall be subject to a
penalty of five hundred dollars ($500.00) that shall be in addition
of the required building permit fees.
