Central Park Apartments
Sustainable Communities Environmental Assessment MMRP-1 Mitigation Monitoring and Reporting Program
This document is the Mitigation Monitoring and Reporting Program (MMRP) for the Central Park Apartments Project (proposed project) proposed in the City of Pasadena. The purpose of the MMRP is to ensure that the required mitigation m easures identified in the Sustainable Communities Environmental Assessment (SCEA) are implemented as part of the overall project implementation. In addition, the MMRP provides feedback to agency staff and decision-makers during project implementation, and identifies the need for enforcement action before irreversible environmental damage occurs.
The following table summarizes the mitigation measures for each issue area identified in the SCEA for the proposed project. The table identifies the actions required for the measure to be implemented, the time at which the monitoring is to occur, the monitoring frequency, and the agency or party responsible for ensuring that the monitoring is performed. In addition, the table includes columns for compliance verification. These columns will be filled out by the monitoring agency or party and would document monitoring compliance. Where an impact was identified to be less than significant, no mitigation measures were required.
This MMRP will be used by City staff or the City’s consultant to determine compliance with permit conditions. Violations of these conditions may cause the City to revoke the operating permit.

CULTURAL RESOURCES
Pasadena General Plan EIR Mitigation Measure: 4.1 : If cultural resources are discovered during construction of land
development projects in Pasadena that may be eligible for listing in the California Register for Historic Resources, all ground disturbing activities in the immediate vicinity of the find shall be halted until the find is evaluated by a Registered Professional Archaeologist. If testing determines that significance criteria are met, then the project shall be required to perform data recovery, professional identification, radiocarbon dates as applicable, and other special studies; and provide a comprehensive final report including site record to the City and the South Central Coastal Information Center at California State University Fullerton. No further grading shall occur in the area of the discovery until Planning Department approves the report.

certificates, list of exact monitoring locations, data
collection protocol, alarming and alerting protocol,
reporting protocol, and maintenance and service
outage protocol. Any of the measures can be removed

x Examples of measures that may be specified for
implementation during demolition or construction include, but are not limited to:
o Prohibition of certain types of impact equipment;
o Requirement for lighter tracked or wheeled
equipment;
o Specifying demolition by non-impact methods, such as
sawing concrete;
o Phasing operations to avoid simultaneous vibration
sources; and
o Installation of vibration measuring devices to guide
decision making for subsequent activities. Monitoring
shall be conducted, at minimum, during all ground-
disturbing significant impa ct construction activities
(i.e., demolition, shoring excavation, and foundation
work). Warning thresholds, as specified in the
monitoring plan, shall be below the specified vibration limits to allow the Contractor to take the necessary
steps to reduce vibration, including but not limited to halting/staggering concurrent activities, utilizing
quieter or lower-vibratory techniques, or reducing the
speed or intensity of equipment. A monitoring record
that documents all alarms and includes information
regarding compliance with these vibration measures
shall be provided to the City of Pasadena upon request.
MM NOI-2: To the satisfaction of the City of Pasadena, in the unanticipated event of discovery of vibration-caused damage, the Professional Structural Engineer and the Project Historical Architect shall document any damage to the existing Green Hotel Apartments and/or restaurant buildi ng located at 84 South Fair Oaks Avenue caused by construction of the project and shall recommend necessary repairs.
