1. Per the geotechnical addendum, the existing landslide meets County minimum factors of
safety based on the analysis for cross-section CC -CC'. However, using the slide plane
strength parameters provided, independent analysis of the existing landslide shown on
cross-section DD-DD' indicates factors of safety below County standard. Verify and
address the possible adverse effect to the proposed grading, structures and offsite
properties. Recommend mitigation as necessary.
2. Independent analysis of the most critical active wedge on the retaining wall indicates
a higher design equivalent fluid pressure. At -rest condition must also be considered
in the design equivalent fluid pressure of proposed basement walls. Verify and
recommend mitigation as necessary.
3. Add the following note on the grading plans:
Per the geotechnical engineering report, temporary vertical cuts exposing daylighted
bedding planes shall be a maximum height of 5 feet.
4. As previously requested, show the following on the grading plans:
a. Approximate limits and depths of existing uncertified fill with the following
note, 'Fill is uncompacted and unsuitable for the support of structures,"
b. Limits and depths of removal and recompaction of all unsuitable materials under
proposed slabs, if applicable.
Location of private sewage disposal system.
c.
5. The Geotechnical Engineer must review the grading plans and sign and stamp the plane in
verification of his recommendations. Original manual signature and wet stamp are
required.
G. Submit two sets of grading plans to the Soils Section for verification of compliance
with County codes and policies.
