About this file

This document is a Mitigation Monitoring and Reporting Program (MMRP) for the Holly Street Bridge Seismic Retrofit Project, prepared by the City of Pasadena in coordination with the California Department of Transportation (Caltrans). The MMRP outlines comprehensive mitigation measures and monitoring requirements across multiple environmental and resource categories to ensure compliance with the Initial Study findings. The program establishes specific timing requirements for implementation, identifies responsible parties for each mitigation measure, and provides a framework for verification of compliance throughout the project lifecycle. Mitigation measures are organized into eight primary categories: Biological Resources (six measures addressing species protection, nesting bird surveys, habitat preservation, and vehicle speed restrictions), Cultural Resources (two measures implementing the Secretary of Interior's Standards for historic property treatment and protocols for archaeological discoveries), Hazards and Hazardous Materials (ten measures addressing asbestos, lead, aerially deposited lead, groundwater contamination, electrical transformers, treated wood waste, and fire prevention), Water Quality (one measure requiring NPDES permit compliance and storm water pollution prevention), Public Services (one measure for emergency response coordination), Recreation (one measure for coordination with park events), Transportation/Traffic (one measure requiring a traffic management plan), and Tribal Cultural Resources (five measures establishing tribal monitoring, consultation protocols, and procedures for unanticipated discoveries of human remains).

Responsibility for implementing and financing mitigation measures is distributed among the City of Pasadena, Caltrans, the Resident Engineer (serving as the City's Construction Manager), and the Construction Contractor. The document specifies that mitigation measures designated as contractor responsibility shall be incorporated into various bid items on the project's Bid Item List. Timing for mitigation implementation spans from prior to construction through post-construction phases, with ongoing monitoring requirements during active construction. Key pre-construction requirements include biological surveys for special status species and nesting birds, environmental testing for hazardous materials including asbestos and lead, groundwater contamination assessment, and retention of a Native American Monitor/Consultant approved by the Gabrieleno Band of Mission Indians-Kizh Nation. During construction, real-time compliance monitoring is required, including the presence of the Caltrans Architectural Historian for historic property oversight, maintenance of no-disturbance buffers around sensitive resources, and daily tribal monitoring logs documenting ground-disturbing activities and any cultural materials encountered. The project is federally funded through the Highway Bridge Program administered by Caltrans, establishing federal compliance requirements for all construction management and environmental monitoring activities.

Biological Resources

BIO-1: Construction personnel shall attend biological awareness training provided by a City approved Project Biologist prior to working within the Project area. The biological awareness training shall include a description of special status species and habitats and provide direction to construction workers if any special status species are observed during construction.

Prior to Construction

City of Pasadena

BIO-2: If any special status wildlife is encountered during the course of construction, work within the vicinity of the wildlife would stop. Work in the vicinity of the wildlife would not re-commence until the wildlife has been relocated by a qualified biologist, or has left the construction area of its own volition. The City, or a City representative, would contact CDFW to determine the most appropriate methods of relocation.

During Construction

City of Pasadena/ Resident Engineer/ Construction Contractor

BIO-3: If vegetation removal or initial work on the super structure of the bridge is to take place during the nesting season (February 1st - August 31st), a pre-construction nesting bird survey must be conducted within 1 week prior to the start of construction. The survey must include all vegetation and potentially suitable structures within the Project vicinity plus a 100-foot buffer. If construction pauses during nesting season for longer than 1 week, another nesting bird survey is required before work can be re-initiated during the nesting season.

A minimum 300 foot no-disturbance buffer would be established around any active nests of raptor species. A 100 foot no-disturbance buffer would be established around any active nests for other migratory birds.

If an active nest is discovered during construction, the contractor must immediately stop work in the nesting area until the appropriate buffer is established. The contractor is prohibited from conducting work that could disturb the birds (as determined by the Project biologist and in coordination with wildlife agencies) in the buffer area until a qualified biologist determines the young have fledged. A reduced buffer can be established if determined appropriate by the Project biologist and approved by CDFW.

Prior to/During Construction

Resident Engineer/

BIO-4: Within 24 hours prior to the start of construction, the Project biologist shall survey chaparral habitats within the Project area for presence of Coastal whiptail. The surveys shall be conducted by walking 5 meter (≈15 foot) transects and pausing periodically to scan the surrounding exposed soils with binoculars for presence of the species.

No further grading shall occur in the area of the discovery until Planning Department approves the report.

Hazards and Hazardous Materials

HAZ-1: Prior to the start of any construction work on the bridge, the City or its contactor shall test for asbestos in the bridge concrete and bearing pads. The requirement for this testing shall be included in the Project Special Provisions. Remediation of asbestos is required in accordance with South Coast Air Quality Management District (SCAQMD) Rule 1403 prior to demolition or renovation. Under the federal asbestos NESHAP, 40 CFR § 61, Subpart M incorporated into California air quality regulations by California Health and Safety Code Section 39658(b)(1) and in compliance with NESHAP regulations, a certified asbestos consultant (CAC) must make definitive conclusions regarding the presence of ACM. The contractor shall hire a CAC to conduct the testing prior to construction.

If hazardous concentrations of asbestos are identified in any structural elements of the Holly Street Bridge that would be impacted during construction, the CAC shall prepare an asbestos remediation and disposal plan. This plan will identify specific measures to be taken during construction to contain asbestos containing materials, ensure worker and public safety, and identify a method for handling, transportation, and disposal of the asbestos containing materials at an appropriate hazardous waste disposal facility.

Prior to Construction

City of Pasadena/

HAZ-2: Prior to the start of construction, the City shall test exposed soil for aerially deposited lead (ADL) adjacent to Holly Street, Linda Vista Avenue, and North Arroyo Boulevard where such soil would be impacted by construction activities. If soil tests identify hazardous concentrations of ADL as defined by the State of California Department of Toxic Substances Control (greater than 80 milligram of lead per kilogram of earth), the City, or its construction contractor, shall prepare a Lead Compliance Plan prior to the start of construction. This plan must outline

Remediation of lead paint is required in accordance with South Coast Air Quality Management District (SCAQMD) Rule 1403 prior to demolition or renovation. A Lead Compliance Plan and Work Plan for the safe testing, removal, storage, transportation, and disposal of lead paint is required prior to the start of removal work by a contractor to ensure work is performed in compliance with health and safety requirements of Title 8 regulations and managed and disposed in compliance with Title 22 regulations. If initial testing identifies lead or chromium is present in paint on the bridge, the contractor will follow the requirements of the Lead Compliance Plan and Work Plan which will provide methods for safe removal, transportation, and disposal of the lead/chromium materials at an appropriate hazardous waste disposal facility.

Prior to Construction

Resident Engineer/

HAZ-4: A site investigation shall be performed to detect any groundwater contamination, including VOCs and perchlorates, within the Project area. The site investigation shall be performed at any locations where excavations would reach a depth of at a minimum of 15 feet below ground surface (bgs) where construction workers would potentially be exposed to groundwater during construction. The site investigation would involve collection of groundwater samples (groundwater is expected to be encountered during geotechnical borings) and testing the samples in a laboratory for VOCs and perchlorate contamination.

If the groundwater testing identifies VOCs or perchlorates, a Contaminated Groundwater Remediation and Disposal Plan shall be required prior to the start of construction. This plan shall outline procedures to ensure worker safety from hazardous groundwater contaminants, as well as identify how the groundwater and saturated spoil soils would be safely contained on-site, or transported to a hazardous waste disposal facility during Project construction.

Resident Engineer/

TCR-3: Unanticipated Discovery of Human Remains and Associated Funerary Objects – Section 5097.94 of the Public Resources Code and Section 7050.5 of the California Health and Safety Code protect Native American burials, skeletal remains and grave goods, regardless of age and provide method and means for the appropriate handling of such remains. If human remains are encountered, work shall halt in that vicinity and the county coroner shall be notified immediately. At the same time, an archaeologist shall be contacted to evaluate the situation. If the human remains are of Native American origin, the coroner must notify the Native American Heritage Commission within 24 hours of such identification. Further provisions of PRC 5097.98 are to be followed as applicable.

Identification and Initial Assessment: Native American human remains are defined in PRC 5097.98 (d)(1) as an inhumation or cremation, and in any state of decomposition or skeletal completeness. Funerary objects, called associated grave goods in PRC 5097.98, are also to be treated according to this statute. Health and Safety Code 7050.5 dictates that any discoveries of human skeletal material shall be immediately reported to the County Coroner. The Resident Engineer shall be responsible for contacting the County Coroner.

A work exclusion zone shall be placed around the discovery and within an area reasonably suspected to overlie adjacent human remains until the coroner has determined the nature of the remains. If the coroner recognizes the human remains to be those of a Native American or has reason to believe that they are those of a Native American, he or she shall contact, by telephone within 24 hours, the Native American Heritage Commission (NAHC) and PRC 5097.98 and CEQA Guidelines 15064.5(e) shall be followed. This includes the NAHC designating and contacting the Most Likely Descendent (MLD). Once notified, the MLD has 24 hours to make recommendations to the City regarding the preferred treatment of the remains and any associated grave goods.

Should a MLD not be identified or should the MLD not respond within 24 hours, then the City shall follow CEQA Guidelines 15064.5(e)(2). It is the City’s responsibility to keep the remains secured until reburial or other appropriate treatment can occur Work may not resume in the discovery area until the remains have been removed and the MLD, or in the absence of a MLD, a qualified archaeologist, has lifted the work exclusion zone limitations.

TCR-4: Gabrieleño Band of Mission Indians-Kizh Nation Human and Funerary Remains: If the Gabrieleno Band of Mission Indians – Kizh Nation is the designated MLD, the following treatment measures shall be implemented. To the Tribe, the term “human remains” encompasses more than human bones. In ancient as well as historic times, Tribal Traditions included, but were not limited to, the burial of funerary objects with the deceased, and the ceremonial burning of human remains. These remains are to be treated in the same manner as bone fragments that remain intact. Associated funerary objects are objects that, as part of the death rite or ceremony of a culture, are reasonably believed to have been placed with individual human remains either at the time of death or later; other items made exclusively for burial purposes or to contain human remains can also be considered as associated funerary objects.

TCR-5: Treatment Measures: In the case where discovered human remains cannot be fully documented and recovered on the same day, the remains will be covered with muslin cloth and a steel plate that can be moved by heavy equipment placed over the excavation opening to protect the remains. If this type of steel plate is not available, a 24-hour guard should be posted outside of working hours. The Tribe will make every effort to recommend diverting the project and keeping the remains in situ and protected. If the project cannot be diverted, it may be determined that burials will be removed. The Tribe will work closely with the qualified archaeologist to ensure that the excavation is treated carefully, ethically and respectfully. If data recovery is approved by the Tribe, documentation shall be taken which includes at a minimum detailed descriptive notes and sketches. Additional types of documentation shall be approved by the Tribe for data recovery purposes. Cremations will either be removed in bulk or by means as necessary to ensure complete recovery of all material. If the discovery of human remains includes four or more burials, the location is considered a cemetery and a separate treatment plan shall be created.

Once complete, a final report of all activities is to be submitted to the Tribe and the NAHC. The Tribe does NOT authorize any scientific study or the utilization of any invasive diagnostics on human remains.

Each occurrence of human remains and associated funerary objects will be stored using opaque cloth bags. All human remains, funerary objects, sacred objects and objects of cultural patrimony will be removed to a secure container on site if possible. These items should be retained and reburied within six months of recovery.

Prior to the continuation of ground disturbing activities, the City and the Tribe shall consult on a location for the respectful reburial of the human remains and/or ceremonial objects. The location of reburial/repatriation shall be within the project footprint or other area which can be protected in perpetuity from all ground disturbing activities. There shall be no publicity regarding any cultural materials recovered or reburied.
