Supplemental Historical Resources Evaluation Report IV Mount Vernon Avenue Bridge Project Summary of Findings The San Bernardino County Transportation Agency (SBCTA), in cooperation with the California Department of Transportation (Caltrans), is proposing to replace the existing Mount Vernon Avenue Bridge (Bridge Number 54C-0066) over the Burlington Northern Santa Fe (BNSF) rail yard in the City of San Bernardino (City), San Bernardino County (County), California. See Attachment A of the Supplemental Historic Property Survey Report (SHPSR) (Number 2), Figures 1, 2, and 3 for the Project Vicinity Map, Project Location Map, and Area of Potential Effects (APE) Map, respectively. The purpose of the proposed project is to provide a bridge that is structurally safe, meeting current seismic, design, and roadway standards. The purpose of this Supplemental Historical Resources Evaluation Report (SHRER) is to identify built environment cultural resources in the APE and to evaluate them for significance pursuant to the National Register of Historic Places (National Register). Preparation of an HRER was originally completed in August 2001 for the proposed bridge replacement project. The State Historic Preservation Officer (SHPO) concurred with the findings of the 2001 Historic Property Survey Report on March 1, 2002. “Cultural resources,” as used in this document, refers to all historical and archaeological resources, regardless of significance. The term “historic property” is defined in the National Historic Preservation Act of 1966 as: “any prehistoric or historic district, site, building, structure, or object included in, or eligible for inclusion on the National Register.” Due to modifications in the bridge design, an SHPSR (Feldman 2007) was prepared, which required changes to the 2001 APE. The results of the 2007 study found that a residence located at 240 North Mount Vernon Avenue that was previously determined eligible for the National Register in 2001 had been demolished in 2003 as a result of a separate action not related to the current undertaking. Documentation relating to the demolition of the historic property was prepared by Caltrans District 8 Cultural Studies staff. No additional properties in the 2006 APE required evaluation. Caltrans approved a Finding of Effect for the undertaking in 2007. Because SHPO did not formally concur with Caltrans’ proposed Adverse Effect finding, Caltrans assumed concurrence and proceed with a Memorandum of Agreement, signed by SHPO in 2009 and later by Caltrans in 2011. Given the length of time since the original 2001 Historic Property Survey Report (HPSR) and the first SHPSR, which was signed in 2007, supplemental Section 106 compliance documents are now required. This SHRER has been prepared to take into account proposed improvements/refinements to the project design since the first SHRER in 2007, which requires Supplemental Historical Resources Evaluation Report S-I Mount Vernon Avenue Bridge Project Summary of Findings additional changes to the APE. As part of this SHRER, built environment resources were identified and evaluated for the National Register, as required by Title 36 of the Code of Federal Regulations Part 800, the regulations for implementing Section 106 of the National Historic Preservation Act of 1966, as amended (Section 106). This SHRER has been prepared in accordance with the First Amended Programmatic Agreement among the Federal Highway Administration, the Advisory Council on Historic Preservation, the California State Historic Preservation Officer, and the California Department of Transportation Regarding Compliance with Section 106 of the National Historic Preservation Act, As It Pertains to the Administration of the Federal-Aid Highway Program in California (Section 106 PA) executed on January 1, 2014. The current investigation resulted in the identification of two previously evaluated historic properties within the APE that were addressed in the previous HPSRs: (1) the Atchison, Topeka and Santa Fe (ATSF) Railway Passenger and Freight Depot (Map Reference Number [MRN] 9), and (2) the Mount Vernon Avenue Bridge (MRN 26). (1) The existing ATSF Depot (Depot) is located west of downtown San Bernardino at 1170 West 3rd Street. The impressive Mission Revival style building (with Moorish influence) was constructed in 1918. In 1975, the Depot was designated a California Point of Historical Interest (CPHI-53). It was later determined eligible for inclusion in the National Register at the local level under Criterion A, for the role the ATSF played in the development of the City and as the headquarters for the
