Upon completion of the rough grading work, and at the final completion of the work under the grading permit, but before the issuance of building permits or release of grading bonds or issuance of a certificate of use and occupancy, the Town Engineer may require:
a. An as-graded grading plan prepared by the civil engineer or other qualified person which shall include corrected original ground surface elevations, if necessary, graded ground surface elevations, lot drainage patterns, engineered slope inclination, and location of all surface and subsurface drainage facilities (final grading).
b. A written approval by the civil engineer certifying the grading as being substantially in conformance with the approved grading plan and specifically approving the following items as appropriate to the project and stage of grading:
1. Construction of line and grade for all engineered drainage devices and retaining walls (rough and final grading).
2. Staking of property comers for proper building location (rough grading).
3. Setting of all monuments in accordance with the recorded tract map (rough or final grading).
4. Location of permanent walls or structures on property comers or property lines where monumentation is not required (final grading).
5. Location and inclination of all engineered slopes (rough and final grading).
6. Construction of earthen berms and positive building pad drainage (rough and final grading).
7. Construction of line and grade for all curbing (final grading).
c. A soil engineering report prepared by the soil engineer, including type of field testing performed, certification of utility trench and retaining wall backfill, 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 approved soil engineering investigation report. Each field density test shall be identified, located on a plan or map, the elevation of test and finish grade elevation shown, and the method of obtaining the in-place density described, using either Uniform Building Code Standard 70-2, ASTM D1557 or the approved equal. The soil engineer shall provide a written approval certifying the adequacy of the site for the intended use, as affected by soil engineering factors, The Town Engineer may require that the soil tests or testing be performed by an approved testing agency.
d. A geology report prepared by the engineering geologist, including 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 as to the adequacy of the site for the intended use as affected by geologic factors and, when required by the Town Engineer, shall submit an as-built geologic map.
e. Any other reports, progress reports, or certifications deemed necessary by the Town Engineer due to the unusual nature of the project or method of construction, or as a result of reviewing the reports required herein.
