BACKGROUND

The Columbia Memorial Space Center is embarking on a second building expansion project (Project) to create a hub of creative and critical thinking for the youth and families of Southeast Los Angeles. This Project intends to create an integrated campus that includes a new building dedicated to bringing the community together through hands-on, minds-on learning to serve the region. The expansions includes: (1) a 39,725 square-foot building that will house the Space Shuttle “Inspiration” along with several exhibits, (2) a 15,300 square-foot building that will include two youth STEM classrooms, and (3) outdoor gathering spaces.

To date, there has been significant work to get the project ready for construction bid, including:

In January 2022, LPA, Inc, the project Architect, began the design of the Project.

Also in 2022, Rachlin Partners LLC/Huckabee, the Project Management/Construction Management firm, began providing its management services.

In 2023, UltraSystems, Inc, the Environmental Consultant, began the environmental analysis of the Project.

In 2024, Knight Building Systems, the Pre-Engineered Metal Building (PEMB) manufacturer, began its design of the PEMB structure for the building.

On June 9, 2026, the City Council approved a Construction Contract with Bernards Bros for the construction of the expansion.

Today, the contractor, Bernards, is preparing to mobilize for construction while Knight Building System is currently completing the fabrication of the PEMB structure offsite.

ANALYSIS
Environmental Services Professional Services Agreement
Construction of the Project will require ongoing compliance with the Mitigation Monitoring and Reporting Program (MMRP) adopted with the Initial Study/Mitigated Negative Declaration certified for the Project. The MMRP includes mitigation measures addressing biological resources (MM BIO-1), cultural and paleontological resources (MM CUL- 1 through MM CUL-3 and MM GEO-1), and tribal cultural resources (MM TCR-1 through MM TCR-7). Implementing these measures requires a qualified environmental consultant to perform preconstruction nesting bird surveys, deliver Worker Environmental Awareness Program (WEAP) training, provide on-call archaeological and paleontological response, coordinate Native American monitors, and document compliance throughout construction. Because these services are professional in nature and require specialized technical qualifications, the City procured a specialized consultant with the required expertise to provide these services.

On March 2, 2026, staff issued Request for Proposals No. 25-006 for Environmental Mitigation Monitoring and Reporting Program Services for the Space Shuttle Exhibit and Education Building. Proposals were received through PlanetBids on March 23, 2026. The City received five (5) proposals from the following firms: Chambers Group, Inc.; ECORP Consulting, Inc.; Eyestone Environmental; Sapphos Environmental, Inc.; and UltraSystems Environmental, Inc.

An evaluation committee comprised of City staff reviewed and scored each proposal using the criteria identified in the RFP, weighted as follows: Project Understanding and Approach (30%), Experience with Similar Projects (30%), Qualifications of Project Team Members (30%), and Overall Quality and Completeness of Proposal (10%).

Based on the evaluation, staff recommends award of the Environmental Services Professional Services Agreement to Chambers Group, Inc. Chambers Group is a California-based, SBE-certified firm with over 46 years of environmental consulting experience and a long-standing record of mitigation monitoring on complex, high-profile public projects. Chambers Group's relevant experience includes ongoing archaeological, paleontological, and tribal cultural resources monitoring at the San Onofre Nuclear Generating Station decommissioning and similar MMRP implementation assignments throughout Southern California. They have demonstrated that they are capable of administering the MMRP and providing the specialized monitoring services required to maintain compliance with the Project's environmental commitments.

Special Inspection Services Professional Services Agreement Chapter 17 of the California Building Code requires special inspection and materials testing for designated structural systems, including the steel, concrete, masonry, and seismic force-resisting elements incorporated into the Space Shuttle Exhibit and Education Building. The project plans identify continuous and periodic inspections that must be performed by an approved special inspection agency, in addition to laboratory testing of soils, concrete, reinforcing steel, structural steel, masonry, and other materials. Because these services are professional in nature and require specialized technical qualifications, the City procured a specialized consultant with the required expertise to provide these services.

On March 18, 2026, staff distributed a Request for Proposals for Special Inspection and Materials Testing Services to on-call firms. Proposals were received on April 8, 2026. The City received three (3) proposals from the following firms: G3 Quality, Inc.; MTGL, Inc.; and Willdan Geotechnical Services.

An evaluation committee comprised of City staff reviewed and scored each proposal using the criteria identified in the RFP, weighted as follows: Project Understanding and Approach (30%), Experience with Similar Projects (30%), Qualifications of Project Team Members (30%), and Overall Quality and Completeness of Proposal (10%).

Based on the evaluation, staff recommends award of the Special Inspection Services Professional Services Agreement to G3 Quality, Inc. G3 Quality is a California-based, SBE-certified firm with over 25 years of experience providing special inspection and materials testing for public agency projects, with local laboratory and inspection resources in Cerritos supported by additional facilities in Redlands, Bakersfield, and Sacramento. They have demonstrated that they are capable of delivering the special inspection and materials testing services required to verify code compliance and support successful Project delivery.

Full construction is anticipated to begin in summer 2026 and be completed by December 2027, with an expected grand opening in Summer 2028.

The second building expansion project represents a key milestone of Phase 1 of the Columbia Memorial Space Center Capital Campaign program. Completion of the construction of the second building expansion and the concurrent restoration of the Space-shuttle Inspiration, which will be housed within the facility, constitutes the completion of Phase I of the project. Phases II and III will follow thereafter. Funding for the follow-on phases of the project, to raise the approximate need of $20 million, is currently underway.

RE: RFP No. 25-006 Environmental MMRP for the Space Shuttle Exhibit and Education Building Dear Matthew Baumgardner,
Chambers Group, a California-based firm with over 46 years of experience with headquarters in Costa Mesa and offices in Los Angeles and San Diego, is excited to submit our proposal to serve as a qualified Cultural Resources consultant for the Environmental Mitigation Monitoring and Reporting Program (MMRP) for the Space Shuttle Exhibit and Education Building Project (Project) for the City of Downey (City).

This project resonates deeply with Chambers Group because our history with the Space Shuttle program began at its very inception. Starting around 1978, and continuing through the early 1980s, we supported environmental monitoring efforts tied to the construction of infrastructure required to receive Shuttle components at Vandenberg Air Force Base. Working in remote coastal environments and demanding marine conditions, our team delivered rigorous environmental documentation that satisfied regulatory concerns while keeping a nationally significant project moving forward. That work required real-time problem solving under challenging field conditions—remote access across gated pasturelands and notoriously rough coastal waters—where divers and small craft operations continuously adapted to wind, surge, and safety constraints while still producing defensible documentation for resource agencies. This early experience established a culture we continue to bring to projects today: be prepared, stay calm under pressure, and deliver compliance work that stands up to scrutiny.

Chambers Group appreciates that successful MMRP implementation is both technical and practical—it requires clear planning, consistent communication, and fast, field-tested decision-making when site conditions change. Our team will support the City’s construction schedule through MMRP implementation, delivering disciplined project management and compliance mitigation support that protects the City’s commitments.

For this Project, our Cultural Resources team can promptly respond and provide the appropriate cultural resources support, as well as provide Native American coordination and consultation support. Our experienced staff is well-versed in supporting the review and preparation of California Environmental Quality Act (CEQA) documents/checklists and any related cultural resources services. We bring a highly skilled team of experts in these fields with local experience, able to provide the City with legally defensible documents and archaeological support in compliance with all established measures.

We are excited to propose for this project not only because it is an important community investment, but because it reflects our history— where disciplined environmental compliance and practical problem solving helped enable one of the most iconic programs in American aerospace. We look forward to partnering with the City of Downey and helping deliver the Space Shuttle Exhibit and Education Building with complete and well-documented environmental compliance.

Understanding of Need
Ability to conduct cultural resources compliance and monitoring activities for projects in construction phases
As a comprehensive environmental consulting firm with over 46 years of experience, Chambers Group, Inc., is a Small Business Enterprise (SBE). We offer a full complement of dedicated staff members who have successfully executed hundreds of cultural resource projects in full compliance with the National Historic Preservation Act (NHPA), the National Environmental Policy Act (NEPA), and CEQA including the full range of cultural resources services.

Federal, state, and municipal agencies have been relying on Chambers Group to keep them in compliance with applicable federal, State, and/or local cultural resource laws, regulations, and guidelines for four decades. We deliver scientific objectivity and credible, easily readable, and legally defensible technical environmental documents. Our expertise enables us to advise clients on complex federal, state, and local regulations and legislation.

Our Cultural Resources Department has a full complement of experienced technical and support staff, including Secretary of the Interior Qualified Archaeologists, Historians, and Architectural Historians, as well as human osteologists/biological anthropologists, and a deep bench of experienced on-call cultural resource professionals. Chambers Group staff are highly regarded experts in the cultural resource management industry and regularly contribute to the science and practice of archaeology within the context of project compliance and construction monitoring.

The Team has experience with the preparation and implementation of all varieties of Cultural Resources Management Plans (CRMPs), (mitigation, monitoring, discovery, and treatment plans), archaeological monitoring, and working in tandem with Native American monitors to ensure compliance with tribal cultural resources mitigation requirements as well.

Chambers Group employs a fully digital workflow for data collection and management to improve the quality of data collected in the field while simultaneously making the process more efficient. The result is our ability to deliver a higher-quality product to our clients at a better value. Our platform streamlines data collection, eliminates re-work and error, and produces report-ready data from the start, resulting in rapid deliverable turnaround times, improving upon traditional data collection and reporting methods.

Chambers Group's digital platform allows a seamless communication interface with the entire Chambers Group team—in the field and in the office. All phases of project work use an interconnected, real-time workflow and are virtually failsafe.

Chambers Group develops and implements necessary mitigation, monitoring, or treatment plans as necessary on a project-by-project basis. We can develop and implement Cultural Resources Worker Environmental Awareness Programs (WEAP) through the preparation and production of a presentation that serves as a tool for construction contractors and Cultural Resource Monitors to use in worker environmental education program training. The program instructs construction personnel about sensitive cultural resources, related procedures, and protocols to follow before any emergency or maintenance activities. The effectiveness of the training program is monitored through performance tracking and feedback.

In addition to the presentation, Chambers Group can compile detailed information on all mitigation measures and requirements that can be provided to Construction Supervisors and monitors. Also, the team can prepare an abbreviated cultural resource WEAP manual/pamphlet (2-3 pages), which provides a summary of cultural/paleontological resource mitigation requirements, including photos and descriptions of the types of resources to likely to occur within project areas. These manuals can be distributed to all project personnel during their training presentation at the initial environmental orientation and can include contact information for applicable City staff, Native American monitor(s), and Chambers Group personnel.

To ensure the recognition of potential cultural resources by non-technical construction personnel, Chambers Group will provide cultural resources sensitivity training for personnel working on project construction. The purpose of this training will be to instruct project personnel on the sensitivity of cultural resources in the project area, protocols for stopping work and notification in the event of findings, and to provide an overview of the laws that govern cultural resources, as well as to introduce them to the Tribe’s perspective on potential impacts. Individuals from potentially affected tribes will be invited to contribute to this training.

A cultural resource discovery could be prehistoric or historic in age. Examples include:
• An accumulation of shell, burned rocks, or an area
of charcoal or very dark stained soil with, or without, artifacts (such features could be cultural middens
or hearths).
• Bones or small pieces of bone (human or
faunal remains).
• Stone tools or waste flakes (projectile points,
arrowheads, or debitage).
• Clusters of tin cans or bottles (refuse
dumps), historic construction materials or
agricultural equipment that appear to be
older than 50 years.
• Buried railroad tracks, decking, or other industrial
materials such as machine parts, storage
containers, water tanks, or other buildings that
appear to be older than 50 years.

Chambers Group’s In-house laboratory facilities
Chambers Group has a secure, 2,400-square-foot laboratory near our Costa Mesa office. The lab space includes a large sink with a sediment trap, size-grading equipment, microscope, artifact photography station, computer workstations, artifact racks for cataloging and analysis, and storage space for housing collections while projects are still in progress. We also have a large reference library for artifact analysis and identification. Having our own lab (instead of outsourcing) allows us to expedite processing, control the process, and maintain the project schedule.

Scope of Services
Task 1: Project Management and MMRP Administration
This Project Management task includes a nominal number of hours to address the necessary Project Management support throughout the Project construction phase(s) that will require compliance with the Project Mitigation Measures (MMs), as outlined in the RFP. This task includes time and costs for up to 50 hours of Project Management to support the necessary coordination and communication to execute all tasks outlined below, in addition to the requested general MMRP administration support for the City. This includes time for necessary task tracking, budget management, invoice reviews, and related coordination. This task also includes time for the Chambers Group Project Manager to support the City with the necessary coordination and communication with the tribal monitor(s) to help ensure compliance with MM Tribal Cultural Resources (TCR)-1 through 7.

As the RFP and related documentation provided did not include Project construction schedule details, this task scope and cost assume a duration of up to 3 months of ground disturbing construction activity (up to 60 days; assuming standard 5-day work weeks, 8-hour workdays, and no weekend, holiday, or overtime work).

Per the RFP, this support shall include regular reporting to the City to confirm ongoing compliance with the MMRP and detailing monitoring actions, responsible parties, and enforcement statuses. Chambers Group assumes that this can be provided with weekly email summary updates to inform the City of ongoing compliance and related activity for the previous week’s activity. Based on the duration assumptions applied, this task includes up to 12 weekly summary updates to the City. If the construction schedule exceeds the Docusign Envelope ID: 07318251-3690-814C-803E-374EB0D49006

RFP No. 25-006 MMRP for the Space Shuttle Building and

assumed 3-month duration, or if Project Management support exceeds the assumed nominal number of hours included with this task for any reason, a change order will be required to address the additional costs.

Assumptions
• The City will provide Chambers Group with confirmation on the Project footprint and all Project-related technical study documentation to inform the services requested and proposed herein. • The City and/or its contractors will provide Chambers Group with more detailed construction schedule information to inform the requested MMRP administration support proposed.

Task 2: Biological Resources Monitoring
Task 2A: Nesting Bird Survey and Report
We understand that a preconstruction nesting bird survey is required per MM BIO-1. Qualified Chambers Group biologists will conduct a preconstruction survey for nesting birds protected by the Migratory Bird Treaty Act (MBTA), California Department of Fish and Game(CDFG) Code 3503 and 3503.5, Federal Endangered Species Act (ESA), California Endangered Species Act (CESA), and other regulations within the proposed Project area and will include a buffer area of 500-feet.

If work occurs during the nesting bird breeding season (generally from February 15 through August 31) of any given year, Chambers Group will conduct a nesting bird survey within the Project site within 7 days before the start of construction activities, to locate any active nests or nest building behavior within and immediately adjacent to the Project site. The survey will be conducted within the Project site and will include a 300-foot buffer for passerines and a 500-foot buffer for raptors, where feasible (Survey Area). Any private property or areas not safely accessible on foot will be surveyed using binoculars. Any active nests or nest building behavior observed during the survey will be documented, and corresponding GPS coordinates will be recorded. Photographs will also be taken to document the active nests observed within the Project site and vicinity. Active nests will be identified by the presence of eggs or young in the nest, white-wash around or below the nest, and/or adults actively bringing nesting material or food to a nest. If an active nest or nests are found, the biologist will map and delineate an avoidance buffer: construction activities shall stay outside of a suitable avoidance buffer (e.g. 300-foot buffer around the active nest, and a 500-foot buffer for common raptors). If the avoidance buffer impedes construction, the avoidance buffer may be able to be reduced depending on the tolerance of the species to the work occurring, and at the discretion of the qualified biologist (agency approval may also be required). No construction shall occur within the avoidance buffer until a qualified biologist has determined that the nest is no longer active. Weekly monitoring will be conducted to determine the status of the nest and determine when the nesting is complete so project activities within the avoidance buffer can resume under Task 2B. Chambers Group will provide an email regarding the results of the nesting bird survey within 24-hours of the survey and will provide GPS coordinates of any active nest location.

Following the preconstruction nesting bird survey, Chambers Group will prepare a summary report documenting the results of the survey. The report will include GPS coordinates for the location of active nests that were present, if found. If no nests were observed, the report will state that no impacts to active nests are anticipated for the proposed project. The report will include up to three graphics including a vicinity map, an active nest location map (if found), and photographs of the site. Chambers Group will recommend protective measures to minimize disturbance to these species during construction activities. If an active nest is observed, the species, nest status, and estimated fledge date will be included in the report. In addition, Chambers Group will discuss areas within the Project site that may be more prone to nests and provide recommendations on how to deter birds from nesting in these areas. The report will contain up to 5 pages of text, including maps and figures.

Schedule and Deliverables: The preconstruction nesting bird survey will be conducted after receiving the notice to proceed. A preconstruction nesting bird survey will be conducted no more than 7 days prior to the Docusign Envelope ID: 07318251-3690-814C-803E-374EB0D49006

start of construction. Following the preconstruction nesting bird survey, a draft report of the survey efforts will be provided to the City within one week of the survey.

Task 2B: Nest Monitoring and Reporting (as needed)
Biological monitors will be available on an as-needed basis. The biological monitor will implement and document compliance with Project avoidance and minimization measures listed in the MM’s and environmental resource agency permits. Measures to be implemented when monitoring may include the following:
• Delineate an avoidance buffer around an active nest or a “no activity” buffer zone. • Conduct periodic monitoring of the active nest and determine when nesting is complete so project activities can resume.
• Document that construction activities comply with the MMs.

For each day the biologist is in the field or required for on-call activities, a daily log will be completed to document biological monitoring activities, protected species observations, protective mitigation measures implemented, or any other relevant biological data. Representative photographs will be taken during monitoring efforts.

Assumptions
• The daily rate for Task 2A assumes eight field hours and includes vehicle use and fuel, personal protective equipment, data management, GIS time, and project management time. If additional time is required to complete the surveys, Chambers Group will discuss the additional scope and provide a change order if necessary.
• Task 2A includes one nesting bird survey. If additional surveys are needed, Chambers Group can provide a change order.
• The cost for Task 2B includes a total of 5 half-days of nest monitoring for one biological monitor. The daily rate assumes three field hours and includes vehicle use and fuel, personal protective equipment, data management, GIS support, and project management time. If additional nest monitoring days are required, Chambers Group will discuss the additional scope and provide a change order if necessary. • This scope of work does not include a Nesting Bird Management Plan (NBMP)or Nest Buffer Reduction Plan. If required, Chambers Group will be pleased to prepare these Plans as a separate scope of work.
• This cost estimate does not include protocol-level surveys for listed or otherwise special status species, coordination with federal or state agencies in the event active nests or special status species are found in the Project area, or the preparation of a special status species management plan. If required, Chambers Group will be pleased to provide these services under a separate cost and scope of work.
• Chambers Group assumes that, by receipt of notice to proceed, full access to the Project area will be provided, including keys to locked gates. Should Chambers Group staff be denied access to the property at the time prearranged, the additional costs incurred by our staff will be billed separately on a time-and-materials basis.
• The cost and schedule are based on our best judgment of the requirements known at the time of the proposal and can be influenced favorably or adversely by agency coordination needs and other circumstances. Chambers Group will endeavor to perform the services and accomplish the objectives within the costs and schedule; however, if the scope of work or schedule changes, Chambers Group reserves the right to revise our costs accordingly.

• GIS data must be submitted in one of the following formats: (1) All Environmental Systems Research Institute (ESRI), AutoCAD compatible; (2) AutoCAD (.dwg or .dxf); or (3) Microstation (.dgn).

Acceptable image formats include: (1) TIF, (2) JPG (J-Peg), (3) SID (Mr. SID), and (4) ECW. If data cannot be exported to one of these formats and it is necessary for Chambers Group to translate the file into a different format, the additional time will be billed on a time-and-materials basis.

Task 3: WEAP Support
Per the RFP and MM CUL-1, Chambers Group cultural resources specialists, under the direction of the Secretary of the Interior’s (SOI) Qualified Archaeologist and Society of Vertebrate Paleontology (SVP) Qualified Paleontologist, will prepare a WEAP Training brochure to be distributed to all Project contractors, subcontractors, and supervisors. The brochure will include pictures and information to help contractor staff in identifying characteristics of cultural and paleontological resources with potential to occur within the Project site, as well as conveying the required avoidance and applicable notification protocols to protect resources if any potential resources are encountered during construction. In addition, the brochure will include general best management practices (BMPs) and relevant contact information. A WEAP Training sign-off sheet will be filled out by each member attending the WEAP training and will be submitted to the City. The draft WEAP document will be submitted to the City for final approval.

Per MM CUL-1 all Project Personnel (including temporary contractors and subcontractors) shall receive WEAP training on the first day of construction activities, conducted in-person on the Project site by a SOI Qualified Archaeologist or SVP Qualified Paleontologist. As such, the cost estimate provided for this task includes the necessary time and related costs for travel to and from the Project site and conducting in-person WEAP training by a single Chambers Group Qualified individual (SOI Qualified Archaeologist or SVP Qualified Paleontologist).

Deliverables: This task scope and cost include preparation and production of up to 50 copies of the WEAP training brochures, and the necessary sign-off sheets utilized to document WEAP training to remain on-site throughout the duration of construction activity. Chambers Group will submit a draft brochure to the City within 2 weeks of receiving Notice to Proceed (NTP). A final version of the WEAP brochure will be submitted within 1 week after receiving all City comments.

Assumptions
• This proposal assumes that all Project-related archaeological and paleontological technical study documentation prepared for the Project can be provided by the City. This documentation may be utilized to inform the WEAP and on-call mitigation support as needed. • This proposal assumes a single Qualified Staff (SOI Qualified Archaeologist or SVP Qualified Paleontologist) shall provide a single in-person WEAP training at the onset of applicable construction activity. If both Qualified staff individuals are required or if additional WEAP trainings are required by Chambers Group staff, a change order will be required to address the additional costs.

Task 4: On-Call Cultural/Paleontological Resources Mitigation Support Per the RFP and MM CUL-2 and GEO-1, Chambers Group will provide the applicable Qualified Staff (SOI Archaeologist and/or SVP Paleontologist) to provide the necessary initial response and mitigation support in the event of an inadvertent discovery of archaeological or paleontological resources during construction. This includes initial on-site assessments and related consultation support to maintain compliance with the related Project MMS pertaining to cultural and paleontological resources.

Per the RFP, Chambers Group understands archaeological and paleontological monitoring is not needed unless a potential resource is uncovered during project activities. In the event of discovery, we will deploy an SOI Qualified Archaeologist and/or SVP Qualified Paleontologist to the Project site. The applicable Qualified staff will conduct the necessary initial significance assessment and related protocols, notification, and/or consultation requirements to ensure compliance with CEQA and the Project MMs and recommend the next Docusign Envelope ID: 07318251-3690-814C-803E-374EB0D49006

appropriate steps based on the initial assessment of the discovery. This includes setting up the 30 or 50-foot exclusion zone around discovery, in conformance with applicable MMs (CU-1, TCR-1). This on-call support applies to MM CUL-3 and TCR-7, and the potential discovery of human remains as well. Chambers Group staff are well-versed in implementing the necessary legal protocols and procedures if a discovery of human remains is encountered during construction.

The cost estimate includes a single response event and initial assessment of inadvertent discovery by the applicable Qualified staff, to be applied as needed to address potential discoveries during Project ground disturbing construction activities. The cost estimate includes time and costs for initial request response coordination, the necessary time and related costs for travel to and from the Project site, time for discovery assessment, and all related on-site consultation and notifications, as well as follow-up email notifications for documentation purposes.

If the discovery is determined significant, and avoidance is not feasible, all subsequent requirements will be determined via consultation between Chambers Group Qualified staff, the City, any participating Native American entities as necessary, and shall be based on the nature and disposition of the discovery. As such, any further support, including any necessary resource documentation or the preparation and implementation of any necessary mitigation, treatment, or data recovery plans, and all associated reporting shall require a change order. If additional response events are subsequently required, the same costs estimated for this on- call support can be applied to a change order.

Assumptions
• This task scope and cost assume up to one single response event, by the applicable Qualified Staff.

This cost can apply as needed to subsequent change orders, if additional responses are required due to the unanticipated discovery of resources.
• This proposal does not include cultural or paleontological resources testing, data recovery, technical reporting, monitoring, or similar programs.

Chambers Group is providing archaeological and paleontological monitoring for cultural and tribal resources coordination support for onshore work at the San Onofre Nuclear Generating Station (SONGS). Services include, in accordance with the final Mitigation and Monitoring Plan (MMP), archeological monitors during all ground disturbing activities that may exceed 3 feet, and paleontological monitors during all ground disturbing activities.

In June 2013, Southern California Edison (SCE) submitted a Certification of Permanent Cessation of Power Operations to the Nuclear Regulatory Commission (NRC), certifying that the company has permanently ceased power operations of SONGS Units 2 and 3. As part of the Decommissioning General Contractor environmental team, Chambers Group has assisted with environmental permitting and compliance strategies, including key CEQA and NEPA-related documents.

Since decommissioning activities commenced in 2019, Chambers Group has provided all archaeological and paleontological compliance monitoring required in conformance with all applicable Project mitigation measures and related mitigation plans and programs adopted for the Project. This includes compliance with all agency requirements for monitoring, associated daily reporting, and coordination as needed with all necessary agency personnel. Chambers Group archaeological and paleontological monitors also support the Air Quality mitigation compliance by conducting the necessary air quality monitoring services. Chambers Group began this compliance support under contract with a different entity. As of January 2025, Chambers Group has been providing archaeological, paleontological, air quality, and biological resources compliance mitigation support under contract with SDS. To date, Chambers Group has successfully completed all necessary contracted mitigation support without any reported incidents of non-compliance and has helped the Project successfully stay on schedule and avoid unnecessary impacts to protected resources.

Chambers Group prepared all environmental documents to satisfy CEQA in support of the City of Newport Beach’s Sunset Bridge pedestrian and bicycle bridge overcrossing at Superior Avenue near the intersection at Pacific Coast Highway in Newport Beach. The Project was to improve pedestrian and bicycle safety and access to Sunset Ridge Park, provide additional parking to better serve organized sporting events, and provide a small recreational component within undeveloped portions of the site.

Since construction of the bridge would be partially funded with federal Congestion Mitigation and Air Quality (CMAQ) funds, federal environmental clearance, mandated by the NEPA, was also required. Technical Studies (air quality, Greenhouse Gas (GHG), energy and noise analyses, initial site assessments, hazardous materials analysis, visual assessment, and photo simulations) and an Initial Study/Mitigated Negative Declaration (IS/MND) were prepared as appropriate CEQA documentation to provide the public and responsible agencies with information about potential environmental impacts associated with the Project. As a part of the NEPA documentation, Chambers Group was responsible for coordination with the California Docusign Envelope ID: 07318251-3690-814C-803E-374EB0D49006

Department of Transportation (Caltrans) Local District and the resulting preparation of a Categorical Exemption (CE) as the appropriate form of documentation.

After providing the appropriate Cultural and Paleontological resources technical studies in support of the Project, Chambers Group supported the City by developing the necessary CRMP and PRMMP. Chambers Group subsequently provided all support to implement the CRMP and PRMMP, including providing both archaeological and paleontological monitors throughout excavation, grading, and trenching activities. During monitoring, significant paleontological resources were identified, and all necessary mitigation and treatment were carried out in compliance with the applicable mitigation measures and protocols outlined in the PRMMP.

This included bulk sediment sampling that was performed with the ongoing construction activities without any unnecessary work stoppage or impact to the ongoing construction schedule.

The City and Project team were recognized by the American Society of Civil Engineers Orange County Branch 2025 for the Outstanding Bridge Project. The City formally dedicated the new Project with a ribbon- cutting ceremony in October 2024.

Camp Bashor Campground, Otay Lakes, San Diego County, CA Client: San Diego-Imperial Council of the Boy Scouts of America (BSOA), Mark Claussen, PE, 858-254- 8765, [email protected]
Total Fees: $541,358.55; Dates: 11/2018 – 10/2024
The Boy Scouts of America Camp Bashor Project (formally known as the Otay Lakes Campground) is located at 2270 Wueste Road in Chula Vista, California, San Diego County. The Project is situated within a 69-acre parcel of County property, south of Otay Lakes County Park. Chambers Group provided cultural resources, Native American monitoring services, and final reports for the San Diego-Imperial Council of the BSOA, in Otay Mesa, San Diego County (County), California.

Chambers Group completed all initial technical studies for the proposed improvements to the Project in support of the IS and MND CEQA review prepared by Chambers Group. Chambers Group assessed the Proposed Project for potential impacts to cultural resources (including archaeological, historical, and tribal cultural) and paleontological resources. These studies were reviewed and approved by County of San Diego Subject Matter Experts (SMEs) and approved with all recommended mitigation related to each respective discipline.

Chambers Group was also employed to provide all required compliance with the adopted mitigation measures pertaining to cultural and paleontological resources. Before construction, Chambers Group provided cultural, paleontological, and tribal cultural resources sensitivity training to all construction personnel and monitors not trained in archaeology. The cultural training informed personnel of avoidance measures and procedures to be followed in the event of unanticipated discovery. Chambers Group Inc also provided the WEAP training to new on-site contractors.

Chambers Group archaeologists performed monitoring during the grading, excavation, and other ground- disturbing activities related to the construction of the Project. Activities included the development of new camping facilities, an archery range, a fire ring, and an amphitheater with an approximately 150-square-foot stage and seating for approximately 100 people. Six challenging outdoor personal experience (COPE) stations were constructed in addition to a permanent zipline structure.

During the activities of the Project, several previously undocumented cultural resources were observed, assessed, and appropriately documented. Because the proper procedures and mitigation measures were recommended by and executed correctly by our team, there were no unnecessary impacts to resources throughout all related construction activities. Additionally, because some of the newly identified resources were determined to be tribal cultural resources through the necessary County and tribal consultation, Chambers Group assisted with the repatriation that was coordinated with the Jamul Indian Village.
