A. A soils study shall be performed to aid in the analysis of the application for permit. Test borings shall be performed on the proposed mining site to determine the subsurface conditions which exist at the site. The number of test bores required shall be determined by the amount of land affected by the mining operations. Three (3) test bores shall be excavated for each site. One additional test bore will be required for each acre of land affected by the mining operation. Test bores shall extend to five feet (5') below the lowest limits of the proposed mining excavation or to the water table. The following information shall be noted at each test bore location:
1. Depth of bore.
2. Depth to high water mark.
3. Depth to water table.
4. Soil stratification and soil type within each stratification. Thickness of each strata.
B. A sieve analysis shall be performed at each test bore on all materials to be removed from the site. A gradation curve shall be developed based on the sieve analysis. All test results shall be submitted to the City for use in reviewing the application for permit. (Prior Code § 7-7-13)
