This section is included in your selections.

A. The soils investigation required by SMC 16.28.020 shall include the following:

1. Field exploration, including test borings and soil samples in sufficient number and extent, in the opinion of the Geotechnical Engineer, to adequately evaluate the surface and subsurface soil nature, distribution and strength for the development proposed.

2. Testing of soil samples by an approved testing laboratory to provide the parameters required by the Geotechnical Engineer to complete the report.

3. A log of all borings, classifying the soil strata by type and depth, to be included in the report.

B. The geotechnical report required by SMC 16.28.020 shall include the following:

1. The nature and extent of any seismic or geologic hazard, the effect of the seismic or geologic conditions on the proposed development, and an assessment of the risk such hazards pose the occupants of the proposed project.

2. An assessment of existing slope stability.

3. Measures needed to mitigate seismic or geologic hazards and to reduce identified hazards to acceptable risk levels in the opinion of the Geotechnical Engineer.

Recommendations for grading procedures and design criteria for erosion control and corrective measures shall be included.

4. Recommendations for site design to minimize seismic or geologic hazards and erosion.

5. Data regarding the nature, distribution and strength of existing soils, building foundation and roadway design criteria, surface and sub-surface drainage criteria and recommended provisions by the Geotechnical Engineer.

6. Recommendations for supervision and observation of grading and other recommended construction work.

7. A plan which shall be drawn to scale, and shall be of sufficient size and clarity to show existing details and the nature and extent of all proposed improvements. The plan shall include the following information:

a. Name and address of owner;

b. Name, address, professional status, license number, phone and fax number of the person who prepared the plan;

c. Location and Assessor’s parcel number of the proposed site;

d. North arrow, scale and the name and location of the nearest public road intersection;

e. Existing contours of the site. Contours shall be sufficiently detailed to define the topography over the entire site (generally at two-foot intervals);

f. Delineation of fault zones, landslides and areas of instability; delineation of springs or other subsurface water conditions;

g. Location of any buildings, structures, trees, and other landscape features on the property and the locations of any buildings, structures or trees on adjacent property within 15 feet of adjoining property lines;

h. Proposed measures to mitigate any seismic or geologic hazards including building setbacks, foundations, surface and subsurface drainage devices, grading, erosion control, retaining walls, special construction techniques, etc.;

i. Phasing of proposed work, as appropriate;

j. A statement by the Geotechnical Engineer regarding the suitability of the subdivision design for the site.

C. The Geotechnical Engineer shall review and approve the final drawings for grading and other geotechnical work for the subdivision as to compliance with the recommendations of his or her report. All grading and geotechnical related work during construction shall be performed under the observation of the Geotechnical Engineer, and subject to periodic testing as recommended in the geotechnical report or required by the City Engineer. Upon completion of all grading and geotechnical construction work, the Geotechnical Engineer shall submit a final report to the City Engineer describing, in detail, all work performed, reconciling the actual work performed with the plans, if different, and expressing a professional opinion that all required work was satisfactorily completed.
