(a) General.
(1) All grading operations for which a permit is required shall be monitored and tested by a testing laboratory acceptable to the city at a frequency acceptable to the City Engineer. The cost and expense of such testing shall be borne by the permittee.
(2) The city, upon at least 36 hours' prior notification from the permittee or his or her agent, shall inspect the work at the following stages of the work and shall either approve the portion then completed, or shall notify the permittee or his or her agent wherein it fails to comply with the requirements of this chapter:
A. Initial. When the site has been cleared of vegetation and unapproved soils have been scarified and/or removed, benched or otherwise prepared and before any fill is placed;
B. Rough. When rough grading has been completed and approximate final elevations have been established; and
C. Final. When all grading has been completed, all drainage facilities installed and slope planting completed and all certifications filed with the city.
(3) In addition to the inspections specified in this section, the city may make such other inspections as it deems necessary to determine that the work is being performed in compliance with the requirements of this chapter.
(b) Testing.
(1) The geotechnical engineer or testing laboratory shall perform sufficient testing during the grading operations to adequately certify that the grading is performed in accordance with the approved plans, specifications and as required by this chapter.
(2) Regular, representative compaction tests and soils samples shall be made on all fills and submitted to the city. The test results, including the dry density, moisture content, location, elevation and sampling date of each sample taken shall be reported, along with sufficient data to correlate with laboratory analyses submitted. A sketch of the locations shall be provided.
(c) Final reports and as-built plans. Upon final completion of the work, the following reports and drawings and supplements thereto shall be submitted to the city: A summary geotechnical report prepared by the geotechnical engineer, including locations and elevations of field density tests, summaries of field and laboratory tests and other substantiating data and comments on any changes made during grading and their effect on the recommendations made in the investigation report. The report shall include a final description of the geology of the site, including any new information disclosed during the grading and the effect of same on recommendations incorporated in the approved grading plan. A certification shall be provided as to the adequacy of the site for the intended use as affected by soil and geologic factors.
