Re: Pacific Electric Trail – PE Trail Eligibility as a Historical Resource Support
Dear Mr. Emrani,
As requested by Caltrans per the Cultural Studies review in the memorandum dated October 21, 2025, the Alta Team with support from Sapphos Environmental, Inc., will address Caltrans Cultural Studies Office (CSO) additional round of comments on the ASR, HRER, HPSR, and APE; cultural resource assessments of eligibility for inclusion in the National Register of Historic Places (NRHP) presented in California Department of Parks and Recreation (DPR) 523-series forms. The additional research and supporting documentation for Caltrans will satisfy the Cultural Studies (HPSR, ASR, HRER, and APE) NEPA review process.
We recognize the importance of staying on schedule and are committed to integrating this scope and fee into the project seamlessly. Unless otherwise noted, this amended scope is an extension of the current scope and fee, not a replacement for agreed-upon activities.
Should you have any questions or desire additional information please do not hesitate to contact Vincent Hellens at (213) 797- 4445 or [email protected].
Sincerely,
Vincent Hellens
Project Manager

Task 1.1.3 – Project Management and Meetings
Sapphos will provide additional project management for the environmental components of the project, including coordination with Alta, Caltrans, and the City to complete the requested revisions to the environmental documentation as part of this scope of work.
Sapphos will attend up to two (2) coordination meetings with Alta with or without the participation of Caltrans and/or the City. The contract can be amended if Sapphos is requested to attend additional meetings with Caltrans, the City, and Alta or any participant combination thereof. Sapphos will provide up to three (3) bi- monthly status updates and up to five (5) monthly emails documenting action items at project meetings.
Sapphos will prepare up to five (5) additional monthly status reports (MSR) and associated invoices to document the progress of the project. Attendance of any Planning Commission, City Council, or historic preservation meetings with the City, beyond those already identified, is not part of this scope, and a contract amendment would be required.
Task 1.1.3 Deliverables:
• Up to three (3) bi-monthly status updates
• Participation in up to two (2) virtual coordination meetings with the Alta with or without the participation of Caltrans and/or the City
• Up to five (5) monthly emails documenting action items from project meetings • Up to five (5) additional MSRs and accompanying invoices

Revisions to Technical Reports
Sapphos will respond to the October 21, 2025, Caltrans CSO Memorandum containing additional comments for revision of the Historic Property Survey Report (HPSR), Historic Resources Evaluation Report (HRER), and Archaeological Resources Survey Report (ASR).
Archival Research
Caltrans has requested Sapphos to conduct in-person archival research at the Southern California Railroad Museum located at 2201 S A Street, Perris, California. Sapphos will coordinate with museum staff to schedule time to access archival materials housed on-site about the Pacific Electric Railway and discuss the built environment resource with museum staff and volunteers who have expertise on the Pacific Electric Railway. It is

understood that archival research gathered in this work effort will be incorporated into the Pacific Electric Railway DPR.
Additional Outreach
Caltrans has requested Sapphos to conduct further coordination efforts to contact key historians with knowledge of the Pacific Electric Railway via an alternative telephone contact number versus email and phone number used during outreach efforts as part of the preparation of the technical documentation. Sapphos will conduct one (1) additional outreach effort to reach the staff at the Pacific Electric Railway Historical Society via telephone and email using the information provided by Caltrans CSO in the October 21, 2025, CSO Memorandum as part of this work effort. Sapphos anticipates that the alternative contact information provided by Caltrans with its additional round of comments will succeed in making contact. Sapphos will document these additional outreach efforts in the appropriate sections of the technical documentation, Section 2 of the HRER and HPSR Attachment D, Public Consultation, and relevant DPR forms.
Revisions to Department of Recreation (DPR) 523 Forms
Sapphos will respond to the additional round of comments provided by Caltrans CSO on October 21, 2025, for all DPRs. In addition, Sapphos will respond to Caltrans CSO requests for additional research and revision to DPRs for (1) the Pacific Electric Railway San Bernardino Line; (2) the PE Rialto Station or Depot in Rialto on Riverside Avenue (south side of the tracks); (3) the Rialto Park Cemetery; (4) Bud Bender Baseball Park; (5) Assembly of God Church; (6) 112 N Olive Avenue; and (7) the Rialto Police Department at 128 N Willow Avenue. The revised DPR forms will be compiled and will accompany the HRER and HPSR.
Sapphos anticipates that following completion of these revisions and resubmittal to Caltrans, Caltrans will then submit the documentation to the State Historic Preservation Office (SHPO) for review and comment or concurrence. Sapphos anticipates participating in two (2) rounds of comments during the SHPO review process.
Task 1.2.3 Deliverables:
• One (1) electronic copy in PDF of Revised ASR, HPSR, HRER, and associated DPR forms with revisions incorporated for submittal to Caltrans CSO
One (1) electronic copy in PDF of Revised ASR, HPSR, HRER, and associated DPR forms with revisions addressing first round of SHPO review
One (1) electronic copy in PDF of Revised ASR, HPSR, HRER, and associated DPR forms with revisions addressing second round of SHPO review

Assumptions
• In response to Caltrans comments dated October 21, 2025, and subsequent meeting with Caltrans cultural resources PQS to clarify needed revisions, Sapphos Environmental, Inc.’s (SEI) built environment team needs to further the evaluation of the Pacific Electric Line by conducting in-person archival research at the Southern California Railway Museum, and extending the effort to communicate with the Pacific Electric Railway Historical Society beyond the three efforts made to date. The results of archival visit and outreach will be included in the existing DPR for the Pacific Electric Railway Line. • Caltrans is requesting additional research and reconsideration of Sapphos proposed assessment of significance for four resources (i.e., Rialto Park Cemetery, Bud Bender Baseball Park, Assembly of God Church, Rialto Police Department). If resources within the Area of Potential Effect (APE) are determined to be historic properties eligible for listing on the National Register of Historic Places as a result of additional research efforts for these four resources, a Finding of Effects (FOE) report will be required for concurrence with SHPO. The FOE was approved as an optional task under Sapphos Contract Amendment #2. Therefore, if the FOE is determined to be necessary by Caltrans or SHPO, no additional cost is required.
• SHPO policy is to complete reviews within 30 calendar days from date of receipt of each submission.
Sapphos has no control over SHPO’s schedule and cannot guarantee SHPO review will entail 30 days. • Sapphos assumes up to five (5) additional MSRs and associated invoices based on the SHPO process and anticipated schedule. Any additional months of MSR and invoicing will require a contract amendment.
