BACKGROUND:
Per San Francisco Building Code Section 106A.4.1.2 (SFBC), as the subject property lies within the Edgehill Mountain Slope Protection Area, a heightened review with Mandatory Submittal and Review of Reports will be required thereto, by the establishment of a Structural Advisory Committee, .as defined by Building Code Section 105A.6 for “all permit applications” submitted to this Department of Building Inspection with the purpose as identified in Building Code Section “106A.4.1.2.2 Purpose Because landslides, earth movement, ground shaking and subsidence are likely to occur on or near the Edgehill Mountain Slope Protection Area, causing severe damage and destruction to public and private improvements, the Board of Supervisors finds that the public health, safety and welfare is best protected if the Building Official of Building Inspection causes permit applications within the Edgehill Mountain Slope Protection Area for either (1) construction of new buildings or structures or (2) alterations that involve a substantial increase in the envelope of an existing building or structure, to be peer reviewed for structural integrity and effect on hillside stability.”

The building construction permit applications are proposing a substantial increase in the envelope of an existing building along a very steep slope along the hillside, and are subject to the requirement of review by Structural Advisory Committee. The Structural Advisory Committee (SAC) will convene to review and provide expert professional opinions concerning items as stipulated in SFBC Section 105A.6.3 and 106A.4.1.2. (attached herein).

The subject permit application is under the jurisdiction of the 2016 edition of the San Francisco Building Code, being the version prevailing at time of permit application with governing language originally legislated by Ord. No. 258-08 eff. 12/8/2008.

As the subject permit application should have been subject to the SAC heightened review before approval and issuance per SFBC Section 106A.4.1.2.4, site permit was issued in error and its reinstatement and approval of the pending construction addendum will be subject to the approval recommendation by the SAC.

The SAC met on March 22, 2021 2 pm, and will meet again to follow-up and review the responses by the applicant team to the SAC review comments issued during the prior review meeting.

This meeting will be held on Tuesday, May 25, 2021, at 1:30 P.M.

NOTE ON PUBLIC COMMENT
The Structural Advisory Committee (SAC) will take public comment on all items appearing on the agenda at the time the item is considered by the SAC. For general public comment (Item No.3), the public may address the SAC on any issues which are in the general subject matter under the jurisdiction of the SAC, other than the calendar items. Each member of the public has up to 2 minutes to comment on an item.

As this SAC review involves complex technical geotechnical, geological, and structural issues and considerations. to facilitate an efficient progress in the review, agenda items 4 to 7 may take place in interlaced fashion for various areas of review concerns as appropriate as determined by the call of the Chairperson.

Per SFBC Section 106A.4.1.2.2, due to the potential of landslides, earth movement, ground shaking and subsidence at or near the proposed site with steep slope area as mapped with potential landslide and/or landslide area within, that could cause severe damage and destruction to public and private improvements, the Board of Supervisor finds that the public health, safety and welfare is best protected if the Director of Building Inspection causes permit applications for the subject alteration building permit application with substantial increase in the envelope of the existing building subject to a heightened design review by independent experts for structural integrity and effect on hillside stability in addition to all other applicable laws and regulations.
Per SFBC Section 106A.4.1.2.3, SAC will perform the design review to provide the Director of Building Inspection with a written report concerning the following review considerations, as applicable:
the safety and integrity of the proposed design and construction;
the effect that grading construction activity related to the proposed project will have on the safety and slope stability of the area during the construction sequence, and after the construction at subsequent development stages, and interim measures to mitigate any potential sliding and erosion of the site;
the validity and appropriateness of the geotechnical/structural design concepts and criteria;
the adequacy of the geotechnical and geological investigation and study and the appropriateness of the recommended design parameters;
the evaluation of the grading design in preparation of the planned future building/structure development, to determine the appropriateness of its capability to perform satisfactorily without failure; any perpetual limitation of the site to be imposed regarding the level of future development, such as the future excavations, and/or vertical and horizontal additions from the original plan.
the constructability of proposed structural details and construction sequencing and methods;
the sufficiency of the proposed inspection, testing and monitoring to be provided prior to, during, and after construction.
items to be reviews will include but not limited to geotechnical and geological investigation and study, designs, details, drainage, erosion during and after construction, construction/erection methods, appropriateness and adequacy of the proposed shoring design, quality control and special inspection specified.
