BIOLOGICAL RESOURCES
Bio 1.A.1: Tree Removal Within Nesting Season (approximately March 1 to August 31). No construction activities of any kind, including but not limited to tree and landscape removal, demolition, site grubbing, grading, etc shall occur until the following protocol is met.
The Project Sponsor, or designated representative shall retain a licensed biologist to conduct a preconstruction survey for protected birds on the site and in the immediate vicinity if any Project construction activities occur during nesting season. The survey shall be done no more than 15 days prior to the initiation of tree removal and grading and other construction activities. In the event that nesting birds are found on the Project site or in the immediate vicinity, Project Sponsor, Biologist or designated representative shall notify the City, locate and map the nest site(s) within three (3) days, submit a report to the City and the California Department of Fish and Wildlife ("CDFW"), establish a no-disturbance buffer of up to or exceeding 250 ft, and conduct on-going weekly surveys to ensure the no-disturbance buffer is maintained. In the event of destruction of a nest with eggs, or if a juvenile or adult raptor should become stranded from the nest, injured or killed, the qualified biologist shall immediately notify the CDFW. The licensed biologist shall coordinate with the CDFW to have the injured bird either transferred to a raptor recovery center or, in the case of mortality, transfer it to the CDFW within 48 hours of notification.
A tree permit per South San Francisco Municipal Code Section 13.30.030 (Tree Preservation Ordinance), shall be required prior to removal of a Protected Tree, defined in section 13.30.020 as: (1) Any tree with a circumference of forty-eight inches or more when measured fifty-four inches above natural grade; or (2) A tree or stand of trees so designated Project Sponsor or Designated
Representative (‘Project
Sponsor’) in collaboration with
Department of Parks and
Recreation to identify a licensed
biologist to conduct
preconstruction survey and
identify measures to protect
nesting birds, if found on site.

by the director based upon findings that it is unique and of importance to the public due to its unusual appearance, location, historical significance or other factor; or (3) A stand of trees in which the director has determined each tree is dependent upon the others for survival. Prior to removing trees, the Project Sponsor, or designated representative shall contact the Parks Division to determine if a removal permit is needed. The Project Sponsor, or designated representative shall obtain City issued tree removal permits prior to commencing any tree removal activities; or (‘Building Division’) for any
demolition permits.
Bio 1.B.1: Tree Removal Outside Nesting Season (approximately September 1 to February 28). No construction activities of any kind, including but not limited to tree and landscape removal, demolition, site grubbing, grading, etc shall occur until the following protocol is met.
Tree removal outside of nesting season would preclude the need for the measures identified in 1.A.1, above. A tree permit shall be required per South San Francisco Municipal Code Section 13.30.030 (Tree Preservation Ordinance)prior to removal of a Protected Tree, defined in section
13.30.020 as: (1) Any tree with a circumference of forty-eight inches or more when measured fifty-four inches above natural grade; or (2) A tree or stand of trees so designated by the director based upon findings that it is unique and of importance to the public due to its unusual appearance, location, historical significance or other factor; or (3) A stand of trees in which the director has determined each tree is dependent upon the others for survival.

Prior to the start of ground disturbing grading, demolition or construction, the Project Sponsor/designated representative shall ensure that a Worker Awareness Environmental Training (WAET) is conducted by a licensed archaeologist (Archaeologist) in the state of California. Training shall be scheduled in consultation with the Project Sponsor/designated Project Sponsor in collaboration
with the Planning Division shall
identify a licensed archaeologist
to conduct the WAET and

representative, construction manager and other key site personnel, and the City of South San Francisco. WAET training shall be required for all personnel participating in ground disturbing construction to alert them to the archaeological sensitivity of the Project area and provide protocols to follow in the event of a discovery of archaeological materials. The Project Sponsor/designated representative shall also ensure the occurrence of the following:
1.A.1.b: Archaeologist shall be on an “on-call” basis to review and identify any potential archaeological discoveries during ground disturbing grading, demolition and excavation operations and work shall stop within 50 feet of the find. Archaeologist shall be contacted for identification, evaluation and further recommendations consistent with California Environmental Quality Act and City of South San Francisco requirements.
1.A.1c: Grading, demolition and any other plans that require soil disturbance shall note that there is a potential for exposing buried cultural resources including prehistoric Native American burials on the site.
1.A.1.d: Archaeologist shall develop and distribute for job site posting an "ALERT SHEET" summarizing potential finds that could be exposed and the protocols to be followed as well as points of contact to alert in the event of a discovery.

Arch 1.B.1: Protocol in the Event of Discovery of Potentially Culturally Significant Soils, Objects or Remains 1.B.1.a: Stop work and contact the on-call archaeologist.
1.B.1.b: Should Archaeologist determine that any cultural resources exposed during construction constitute a historical resource and/or unique archaeological resource under CEQA, Archaeologist shall notify the appropriate parties of the evaluation and recommend mitigation measures to mitigate to a less-than significant impact in accordance with California Public Resources Code Section 15064.5. Mitigation measures may include avoidance, preservation in-place, recordation, additional archaeological testing and data recovery among other options. The completion of a formal Archaeological Monitoring Plan (AMP) and/or Archaeological Treatment Plan (ATP) that may include data recovery may be recommended by the Professional Archaeologist if significant archaeological deposits are exposed during ground disturbing construction. Development and implementation of the AMP and ATP and treatment of significant cultural resources will be determined by the project proponent in consultation with any regulatory agencies.
The treatment of human remains, and any associated or
unassociated funerary objects discovered during any soil-disturbing activity within the Project site shall follow the requirements of section 5097.99 of the Public Resources Code). This shall include immediate notification of the appropriate county Coroner/Medical Examiner, Project Sponsor and the City of South San Francisco.
1.B.1c: A Monitoring Closure Report shall be filed with the Applicant/Project Sponsor/designated representative and the City at the conclusion of ground disturbing construction if archaeological and Native American monitoring of excavation was undertaken.

Geology and Soils
Geology and Soils Mitigation 1: An updated geotechnical report(s) shall be provided to the City for peer review prior to any issuance of building, grading, grubbing or tree removal permits. The updated report(s) shall address the revised Project description and include all design measures requisite to be compliant with the California Building Code. The updated report(s) shall include at a minimum, structural design and construction specifications, including but not limited to, undergrounding of utilities addressing any construction requirements for potentially and/or corrosive soils, grading, site stabilization, drainage, utility and infrastructure design and placement, foundation design, retaining wall specifications, and soil compaction requirements and design. The report(s) shall be peer reviewed by the City’s consultant and revised accordingly until determined complete.
The maximum seismic protections identified to date are implemented through the provisions of the Title 15 of the City’s Municipal Code (Building Code) which was updated in 2021 (City Ordinance 1628-2021).
These measures are implemented through the building permit process and coupled with an updated geotechnical review would reduce Project impacts to less than significant.
