加州高鐵管理局（管理局）作為聯邦牽頭機構的角色是根據地面交通項目交付計劃授權的，也稱為 國家環境政策法 (NEPA) 任務，根據美國法典第 23 篇第 327 節以及 2019 年 7 月 23 日聯邦鐵路管理局 (FRA) 與加利福尼亞州 (州) 之間通過加利福尼亞州運輸署行事的諒解備忘錄 (MOU) 和權威。諒解備忘錄規定，FRA 就諒解備忘錄中確定的鐵路項目指定並承擔 FRA 遵守 NEPA 和其他聯邦環境法的責任，包括環境審查、諮詢和其他必要行動的責任。為履行諒解備忘錄規定的職責，國家被視為 FRA。這些指定的聯邦職責由管理局履行，並由加利福尼亞州交通局和州監督。諒解備忘錄中分配給國家的鐵路項目包括管理局的項目、直接連接到加州高速鐵路系統和 ACE 車站的某些鐵路項目向前 project within the Altamont Corridor Express system. The Stockton Diamond project is sponsored by the San Joaquin Regional Rail Commission (SJRRC) and is a part of the ACE向前 項目套件。
項目狀態： As of July 28, 2022, the Authority and SJRRC have completed the NEPA process for the Stockton Diamond Grade Separation Project (Project), and the Final EA and FONSI are available on the Stockton Diamond website at the link below. After the close of the 30-day public comment period for the Draft EA on April 27, 2022, the Authority and SJRRC continued the NEPA process and reviewed comments, provided responses, and prepared the Final EA. Please refer to the SJRRC project website for complete Project documents and information, including current status of all Project phases.
聖華金地區鐵路委員會 (SJRRC) proposes to construct the Stockton Diamond Grade Separation Project (Project), a critical passenger and freight mobility project that would construct a grade separation of the existing at-grade crossing of BNSF Railway (BNSF) and Union Pacific Railroad (UP) freight rail lines at the existing Stockton Diamond rail intersection. The SJRRC is the lead agency under the California Environmental Quality Act (CEQA) and joint lead agency under the National Environmental Policy Act (NEPA). The California High-Speed Rail Authority (Authority) is the federal lead agency under the NEPA Assignment Program.
On August 19, 2020, SJRRC officially launched the environmental review process for the Stockton Diamond Grade Separation Project (Project) with a Notice of Preparation (NOP) for an Environmental Impact Report (EIR). When the NOP was issued, the environmental document was presented to stakeholders and the public as a joint CEQA/NEPA document. SJRRC, as the CEQA Lead Agency in coordination with the Authority as the NEPA Lead Agency, under assignment from the FRA, was to prepare an EIR/Environmental Assessment (EA). Due to funding deadline considerations, the CEQA/NEPA document was split, and SJRRC prepared an EIR for the Project, which was adopted by the SJRRC Board on June 4, 2021. SJRRC and the Authority then jointly prepared a Draft EA and Final EA for the Project in conformance with NEPA. SJRRC is the Project sponsor and joint lead agency under NEPA.
The Project is located just south of Downtown Stockton near South Aurora Street and East Scotts Avenue in the City of Stockton in San Joaquin County, California. The area of impacts is bounded by Robert J. Cabral Station to the north; the UP Stockton Yard to the south, located approximately at East Fourth Street; South Pilgrim Street to the east; and South Grant Street to the west (See Figure 1 below).
The Project would construct a grade separation of the BNSF and UP rail lines by elevating the UP mainline tracks over the BNSF mainline tracks to reduce rail congestion and allow passenger and freight rail traffic to flow uninterrupted through the crossing. Currently, the BNSF Stockton Subdivision and the UP Fresno Subdivision consist of two main tracks each, and they intersect each other at a level, at a grade crossing known as the Stockton Diamond. This rail intersection is the busiest at-grade railway junction in California. The at-grade crossing experiences substantial congestion and delays service for passengers and freight throughout the Central Valley—and for freight on the broader national network. The current, at-grade configuration of the tracks results in critical delays to passenger and freight trains in the area, including those serving the Port of Stockton. Train congestion also causes vehicle delays at roadway-rail crossings and creates potential motor vehicle, rail, bicycle, and pedestrian conflicts. Reducing those conflicts improves safety, access, and mobility for City of Stockton residents through crossing closures, as well as bike, pedestrian, and roadway improvements at multiple roadway/railway grade crossings.
The SJRRC owns and operates the Altamont Corridor Express program of passenger rail projects that connect Stockton and San Jose. 聖華金聯合權力機構 (SJJPA) manages the Amtrak San Joaquins intercity passenger rail service. The current ACE and San Joaquins intercity passenger rail services are constrained by the at-grade Stockton Diamond Interlock at-grade crossing, which can reduce reliability and on-time performance for both passenger and freight rail service. The grade separation would help improve the operational performance for SJRRC and the SJJPA as they provide service between the Central Valley, Sacramento, and San Francisco Bay Area. Transit in San Joaquin County is also important to the region and includes a system of bus rapid transit, intercity and interregional bus transit services, ACE commuter rail service, and San Joaquins intercity rail service.
The Project’s public benefits would extend to motorists, pedestrians, rail passengers, freight shippers, and residents throughout the region. Additional benefits would include reduced fuel consumption, lower freight rail transportation costs, and improved travel times and reliability. As described and explained in the EA, the Project would result in overall beneficial effects on long-term air quality, traffic and transportation, and visual quality and aesthetics in the Project Study Area.
