MITIGATION MONITORING AND REPORTING PROGRAM
Infinite 131 Project
City of South San Francisco
State Clearinghouse No. 2023110023
1 The environmental impact report (EIR) for the Infinite 131 Project (proposed project or project) identifies the mitigation measures that will be implemented to reduce the environmental impacts associated with the proposed project. The California Environmental Quality Act (CEQA) requires a public agency to adopt a monitoring and reporting program for assessing and ensuring compliance with any required mitigation measures applied to proposed development. As stated in Section 21081.6(a)(1) of the Public Resources Code:
The public agency shall adopt a reporting or monitoring program for the changes made to the project, or conditions of project approval, adopted in order to mitigate or avoid significant effects on the environment.
Section 21081.6 also provides general guidelines for implementing mitigation monitoring programs.
The mitigation monitoring table lists those mitigation measures that may be included as conditions of approval for the project. To ensure that the mitigation measures are properly implemented, a monitoring program has been devised that identifies the timing and responsibility for monitoring each measure. The first column identifies mitigation measures that were identified in the EIR. The second column, entitled “Action Required,” refers to the action that must be taken by the implementing party, usually the project applicant, to ensure implementation of the measure. The third column, entitled “Monitoring Timing,” refers to when the monitoring will occur, ensuring that the action will be completed. The fourth column, “Monitoring Responsibility,” refers to the agency responsible for overseeing or ensuring that the mitigation measure is implemented. The fifth column, entitled “Compliance Verification,” is where the Responsible Agency verifies that the measures have been implemented.

In recent years, due to the large volume of
submissions generated by environmental
mitigation requirements, NPS and the

indicating that they will not accept formal
submissions under the HABS, Historic
American Landscape Survey (HALS), and
Historic American Engineering Record
(HAER) programs unless the resource being
documented is a rare, unusual, or
exceptionally high-quality example of its
type. Therefore, documentation at a similar
level and formatting—HABS like, with
standard photography, written narrative,
measured drawings—shall supplement
documentation standards without formal
submission to NPS for review and approval.
Instead, the prepared documentation shall
be prepared informally for distribution to

striping for pedestrian crosswalks and
“YIELD TO PEDS” signs would be
incorporated where necessary and
within project limits.
4. Signalization of the San Mateo
Avenue/Shaw Road/Tanforan Avenue
Intersection: The project shall
implement a new traffic signal at the
intersection of San Mateo Avenue/Shaw
Road/Tanforan Avenue. This traffic
signal would facilitate access to the
project site via Shaw Road while
reducing potential for multimodal
conflicts. The traffic signal shall be
accompanied by accessible sidewalk
and curb ramp upgrades at the
intersection as well as associated signal
and intersection/sidewalk
modifications at the adjacent San Mateo
Avenue/South Linden Avenue
intersection.
5. Engineering Study of a New
Southbound U.S. 101 Off-ramp
Connecting to the Utah Avenue
Overpass: The project shall fund an
engineering study of a new
southbound U.S. 101 off-ramp
connecting to the proposed Utah
Avenue overpass as envisioned in the
general plan and Lindenville Specific
Plan. The engineering study shall be
led by the City. As currently

envisioned, the overpass would not
include a southbound off-ramp. A
second off-ramp would facilitate more
direct access to the overpass and
address long-term queueing concerns.
The off-ramp would be accompanied
by a new street connection between
Utah Avenue and Produce Avenue
north of the project site.
6. Engineering Study and Fair-share
Contribution toward a New Trail
Crossing of U.S. 101 South of the Project
Site: The project shall fund an
engineering study for a new Class I
shared-use path crossing of U.S. 101 to
connect the Bay Trail with Shaw Road.
The engineering study shall be led by
the City. An engineering study of the
planned U.S. 101 crossing has not yet
occurred, and a preferred alternative
alignment has not been determined.
The engineering study will consider
potential trail crossing alignments,
incorporate the preferred alternative
alignment into its site plan, and
quantify a fair-share contribution
toward construction of the crossing.
The mitigation shall be completed by the
applicant prior to the project receiving a
certificate of occupancy. If the City
implements these improvements in advance
of the project’s construction, the project
shall reimburse the City for the cost of
construction. If another development

implements these improvements and/or
engineering studies prior to the project’s
construction, the project shall be
responsible for a fair-share reimbursement
of construction costs to the developer
leading these improvements. This funding
will ensure that transportation facilities
serving the project site are appropriately
sized to handle multimodal travel demand
associated with the project, as envisioned in
each plan.
