The term sustainability is often defined as the capacity to endure. Sustainability speaks to decision making that considers the impacts of the actions taken now, on future generations. When developing major infrastructure for the California High-Speed Rail Program, program designers must consider factors that safeguard the capacity of future generations to enjoy quality life:

  • Environmental
  • Economic
  • Political
  • Cultural

The California High-Speed Rail Authority (Authority) is committed to building a high-speed rail system that minimizes impacts to both the natural and built environment, encourages compact land development around transit stations, and helps California manage its pressing issues with climate change, traffic and airport congestion, and energy dependency. The Authority has adopted policies and published several documents that confirm a commitment to sustainable development.

2021 Sustainability Report

The 2021 Sustainability Report provides information on the progress the Authority is making in fulfilling sustainability commitments. Specifically, this report:

  • Details the characteristics of the program that – based on feedback from the public, state legislators and the Authority’s internal experts – most clearly express sustainability.
  • Outlines the commitments, methodologies, progress and results of the program’s comprehensive approach to designing, constructing and operating high-speed rail in a sustainable manner.
  • Reflects the priorities and concerns of the program’s many stakeholders – including community leaders, elected officials, partner organizations, Authority employees and contractors, sustainability peers and organizations – and the people who will travel on the system.
  • Discusses the results of the materiality assessment process performed in 2018. The Authority and the high-speed rail program have passed various project milestones since the process was completed in 2014/2015, making it prudent to validate and refresh material topics covered in our sustainability program and reporting.
  • Highlights our updated Sustainability Policy, which was adopted by the Board of Directors in April 2019. The updates to the policy included refinements to priorities, objectives and commitments, and a clear delineation by program phase.
  • Outlines the progress marked by several achievements.

Urban Design Guidelines

The California High-Speed Rail Authority’s Urban Design Guidelines are a comprehensive planning guide that provides domestic and international examples of station area design, urban design and transit-oriented development. This guide includes simple diagrams that analyze and explain successful public places and how each promotes livability and transit use.  Urban design implemented around high-speed rail stations can encourage destination stations and enhance the value for the surrounding community.

The Urban Design Guidelines report is intended to be used by cities and communities throughout the state’s 800-mile system as they work with their stakeholders and residents to create a vision for their high-speed rail station areas.

Sustainable Design Concepts

High-speed rail will provide the Central Valley with improved access to the rest of the state, putting the Central Valley’s residents only one to two hours away from California’s major employment and population centers. This change in the Central Valley’s geography of access will in turn impact the course of future development within the region. At the regional scale, the increased accessibility afforded by high-speed rail can serve to concentrate development in and around communities that have stations. Such demand can shift the impetus of new growth away from the Central Valley’s agricultural land and reorient it towards established urban centers.

Vision California

“Vision California” is an unprecedented effort to explore the critical role of land use and transportation investments in meeting the environmental and fiscal challenges facing California over the coming decades.  Calthorpe Associates is producing tools that can evaluate alternative physical visions for how California can accommodate anticipated growth. The project will model the consequences of varying land use and transportation scenarios, and quantify the benefits of a more sustainable, transit-oriented future for California–one that is anchored by a statewide high-speed rail network.

Urban Forestry Program

Honoring its commitment to zero-net direct greenhouse gas emissions in construction, the California High-Speed Rail Authority (Authority) is pleased to present the details of the first group of urban forestry projects. CAL FIRE, in partnership with the Authority, awarded $2.5 million in tree planting grants to offset greenhouse gas emissions associated with construction of the first portion of the high-speed rail system. In total, more than 7,000 urban trees were planted. A separate part of the agreement with additional funding also funded more than 1,800 acres of forestland planting. These trees will capture 143,000 metric tonnes of greenhouse gases over the project lifetime, while providing numerous environmental, social, and economic benefits to disadvantaged communities in the vicinity of the rail line between San Jose to Anaheim.

The urban forestry grants:

  • Funded tree planting projects to reduce greenhouse gas levels
  • Arrested the decline of urban forests and improved their structure and function
  • Increased climate change resilience
  • Improved the quality of the environment in urban areas
  • Optimized co-benefits to urban residents

The interactive Urban Trees Map shows the locations of the urban trees, a summary of the eco benefits they will provide over the project lifetime, and the most common species planted. You can click on a species to show its benefits or click on an individual tree for more information about it.

  • Tree Fresno – $1 million grant
    • 3,115 trees were planted in schools, parks, and in residential areas in disadvantaged communities in the greater Fresno region
    • An emphasis was placed on planting the largest trees possible, as these provide the greatest greenhouse gas benefits
    • Species were chosen wisely for drought tolerance and to make use of water-wise irrigation
    • Educational opportunities, including curricular activities, were provided with the tree plantings
    • Tree Fresno cared for the trees for the length of the grant and ongoing maintenance will be provided by the property owners
    • Plantings began in spring of 2018 and concluded in the spring of 2021
  • California Urban Forests Council – $1.5 million grant
    • 4,063 trees were planted in disadvantaged communities along the rail corridor, half in public areas and half in residential areas
    • CUFC worked to build a network of urban forestry support to create greener, cleaner communities by working with local partners in disadvantaged neighborhoods
    • Informational and outreach opportunities were provided to engage residents and train volunteers in tree care
    • Partners provided care for the trees for the length of the grant and ongoing maintenance will be provided
    • Plantings began in spring of 2019 and were completed a year later
