[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.
