1 NEW PARK AT LINDEN AND PINE PROJECT (NOVEMBER 2025)
MITIGATION MONITORING AND REPORTING PROGRAM
This Mitigation Monitoring and Reporting Program (MMRP) has been prepared for the New Park at Linden and Pine Project (project) pursuant to the California Environmental Quality Act (CEQA) Guidelines (California Code of Regulations, Title 14), which state:
Section 15097. Mitigation Monitoring and Reporting
(a) In order to ensure that the mitigation measures and project revisions identified in the EIR or negative declaration are implemented, the public agency shall adopt a program for monitoring or reporting on the revisions which it has required in the project and the measures it has imposed to mitigate or avoid significant environmental effects. A public agency may delegate reporting or monitoring responsibilities to another public agency or to a private entity which accepts the delegation; however, until mitigation measures have been completed the lead agency remains responsible for ensuring that implementation of the mitigation measures occurs in accordance with the program.
(c) The public agency may choose whether its program will monitor mitigation, report on mitigation, or both. “Reporting” generally consists of a written compliance review that is presented to the decision-making body or authorized staff person. A report may be required at various stages during project implementation or upon completion of the mitigation measures. "Monitoring" is generally an ongoing or periodic process of project oversight. There is often no clear distinction between monitoring and reporting and the program best suited to ensuring compliance in any given instance will usually involve elements of both.
The choice of program may be guided by the following:
(1) Reporting is suited to projects which have readily measurable or quantitative mitigation measures or which already involve regular review. For example, a report may be required upon issuance of final occupancy to a project whose mitigation measures were confirmed by building inspection.
(2) Monitoring is suited to projects with complex mitigation measures, such as wetlands restoration or archeological protection, which may exceed the expertise of the local agency to oversee, are expected to be implemented over a period of time, or require careful implementation to assure compliance.
(3) Reporting and monitoring are suited to all but the most simple projects.
Monitoring ensures that project compliance is checked on a regular basis during and, if necessary after, implementation. Reporting ensures that the approving agency is informed of compliance with mitigation requirements.
The MMRP table lists the adopted mitigation measures identified in the New Park at Linden and Pine Project Initial Study/Mitigated Negative Declaration (IS/MND). The table also describes the timing for mitigation measure implementation (e.g., when the measure shall be implemented) and the parties—such as the Construction Contractor and/or City of South San Francisco (City) and/or City Representative— that are responsible for ensuring implementation of all aspects of each measure. Additionally, the MMRP table identifies the conditions under which each measure will be considered complete.

Biological Resources
BIO-1 Minimize Impacts to Nesting Birds: The following measures shall be implemented to minimize impacts to nesting birds, as required by the Migratory Bird Treaty Act:
a. If project activities, including, but not limited to, tree removal or pruning, grubbing, and grading, are conducted during nesting bird season (February 15–September 15), the City of South San Francisco or its contractor shall conduct preconstruction nest surveys in and near the project site (within 500 feet for large raptors and 300 feet for all other birds) by a qualified biologist within 7 days of the start of construction. If nesting birds are identified during the preconstruction survey, then the City of South San Francisco shall modify the project as necessary (i.e., a nowork exclusion buffer of appropriate size [which, if implemented, shall be determined by a qualified project biologist] shall be erected around active nests) and/or delay the project as necessary to avoid impacts to the identified nests, eggs, and/or young. Disturbing active nests must be avoided until young birds have fledged.
