(1) Permits required. Except as exempted in this Chapter, no person shall do any grading without first obtaining a grading permit from the Community and Economic Development Building Official. A separate permit shall be obtained for each site, and may cover both excavations and fills.
(2) Application. The provisions of this Chapter are applicable to grading. Additionally, the application shall state the estimated quantities of work involved.
(3) Grading designation. Grading in excess of five thousand (5,000) cubic yards (3825 m3) shall be performed in accordance with the approved grading plan prepared by a civil engineer, and shall be designated as "engineered grading." Grading involving less than five thousand (5,000) cubic yards (3825 m3) shall be designated "regular grading" unless the permittee chooses to have the grading performed as engineered grading, or the Building Official determines that special conditions or unusual hazards exist, in which case grading shall conform to the requirements for engineered grading.
(4) Engineered grading requirements. 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 an individual licensed by the state to prepare such plans or specifications when required by the Community and Economic Development Building Official.
Specifications shall contain information covering construction and material requirements. 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 sheet of each set of plans shall give location of the work, the name and address of the owner, and the person by whom they were prepared.
The plans shall include the following information:
(a) General vicinity of the proposed site.
(b) Property limits and accurate contours of existing ground and details of terrain and area drainage.
(c) Limiting dimensions, elevations, or finish contours to be achieved by the grading, and proposed drainage channels and related construction.
(d) 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.
(e) 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 that are within fifteen feet (15') (4572 mm) of the property or that may be affected by the proposed grading operations.
(f) Recommendations included in the soils engineering report and the engineering geology report shall be incorporated in the grading plans or specifications. When approved by the Building Official, specific recommendations contained in the soils engineering report and the engineering geology report, which are applicable to grading, may be included by reference.
(g) The dates of the soils engineering and engineering geology reports together with the names, addresses, and phone numbers of the firms or individuals who prepared the reports.
(5) Soils engineering report. The soils engineering report 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 opinion on adequacy for the intended use of sites to be developed by the proposed grading as affected by soils engineering factors, including the stability of slopes.
(6) Engineering geology report. The engineering geology report 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 opinion on the adequacy for the intended use of sites to be developed by the proposed grading, as affected by geologic factors.
(7) Liquefaction study. The Building Official may require a geotechnical investigation in accordance with this Chapter when, during the course of an investigation, all of the following conditions are discovered, the report shall address the potential for liquefaction:
(a) Shallow ground water, fifty feet (50') (15 240 mm) or less.
(b) Unconsolidated sandy alluvium.
(c) Seismic Zones 3 and 4.
(8) Regular grading requirements. Each application for a grading permit shall be accompanied by a plan in sufficient clarity to indicate the nature and extent of the work. The plans shall give the location of the work, the name of the owner, and the name of the person who prepared the plan. The plan shall include the following information:
(a) General vicinity of the proposed site.
(b) Limiting dimensions and depth of cut and fill.
(c) Location of any buildings or structures where work is to be performed, and the location of any buildings or structures within fifteen feet (15') (4572 mm) of the proposed grading.
(9) Issuance. The provisions of this Chapter are applicable to grading permits. The Building Official 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. The Building Official may require professional inspection and testing by the soils engineer. When the Building Official has cause to believe that geologic factors may be involved, the grading will be required to conform to engineered grading.
