Strategies for Meeting Today’s Faster NEPA Schedule Requirements

Reflections From the Successful Environmental Process for Austin’s Light Rail Project

Earlier this year, the Austin Transit Partnership (ATP) hit a significant milestone when the proposed 9.8-mile Austin Light Rail project became the first major transit project to complete a Federal Transit Administration (FTA) Final Environmental Impact Statement and Record of Decision process (FEIS/ROD) in under two years. This achievement stands as one of the fastest major FTA environmental reviews in recent history. It also demonstrates the United States Department of Transportation’s commitment to meeting the mandates established in the Bipartisan Infrastructure Law and Fiscal Responsibility Act of 2023 for a streamlined environmental review.

Similar large transit projects have taken four to five years to advance through the federal National Environmental Policy Act (NEPA) requirements. Austin’s experience set a new national benchmark for transit projects and the broader infrastructure industry. It also proved that new federal timeline commitments — one year for an environmental assessment (EA), two years for an EIS — can be met.

As the NEPA lead on the Austin Light Rail project, HDR worked closely with ATP to develop and execute an approach that led to this success. By focusing on proactive preparation, strong stakeholder coordination, adaptability to evolving project conditions, and a commitment to leveraging the NEPA process for community engagement, the team met all NEPA requirements and kept the new light rail program on schedule under FTA’s New Starts Capital Investment Grant funding program.

More Public Transit Needed — Quickly

Austin’s population isn’t just growing, it’s booming.

According to the most recent U.S. Census Bureau estimates, as analyzed by local tracking organizations, the Greater Austin metropolitan area is adding roughly 159 new residents every day. This surge of new residents has increased congestion on the region’s roadways. Austin commuters lost an average of 64 hours to gridlock in 2024, trailing only Houston at 77 hours and Dallas at 69 hours among Texas metros, according to the Texas A&M Transportation Institute’s 2025 Urban Mobility Report.

The region’s transit and transportation infrastructure has not kept pace with this growth. Rising travel demand has resulted in longer travel times, decreased mobility and additional travel costs for residents and businesses.

In response to these challenges, Austin voters in 2020 approved a public transit expansion initiative called Project Connect. The tax initiative provides local funding that will be used to leverage federal dollars for a new light rail network and critical systemwide infrastructure enhancements. ATP, a local government corporation, was created to implement the new transit initiatives. With support from the City of Austin and CapMetro, the region’s public transportation provider, ATP quickly got to work on advancing the region’s first light rail system. Navigating the federal environmental process was one of the first steps to accessing federal funding.

Unlike highway projects that benefit from automatic federal funding allocations each year, transit agencies must compete nationally for capital funding. Based on competitive FTA project evaluation criteria, the stronger the project, in terms of cost effectiveness and achieving timely planning milestones, the better the chance for securing federal funding. Federal selection for these funds heavily favors transit projects based on the project’s readiness to advance from planning to construction. Efficient planning that meets federal requirements (e.g., meeting the two-year NEPA deadline) signals that a project is highly viable, significantly strengthening its competitiveness in a volatile federal funding market.

Proactive Preparation and PEL Study Process

The two-year NEPA deadline begins with the publication of the Notice of Intent (NOI) to prepare an Environmental Impact Statement (EIS) in the Federal Register. Completing time-consuming tasks prior to the publication of the NOI is critical to meeting that deadline. For the Austin Light Rail project, early preparation for the NEPA process and an expedited and collaborative review of thousands of pages of technical analysis was essential before initiating the EIS.

To address limited federal staffing availability for document review, FTA relied on supplemental review staff to avoid delays that could result from staffing constraints. In addition, regularly scheduled project progress meetings that included FTA, FTA review support staff, ATP and HDR helped the team maintain the schedule. These frequent meetings fostered a shared sense of partnership, built trust, promoted collaboration and leveraged the team’s collective technical experience and commitment to the shared goal.

At HDR’s recommendation, ATP and FTA agreed to use the Planning and Environmental Linkages (PEL) study process before initiating the EIS analysis. PELs are often used to eliminate time-consuming early planning requirements, identify long-lead technical issues before they impact the NEPA schedule, build stakeholder consensus, evaluate alternatives and reduce project risks. For Austin, the PEL process allowed adoption and incorporation, by reference, of the pre-NEPA alternative analyses, and early project scoping activities, which reduced NEPA redundancy and saved time once the EIS process began.

ATP also established a comprehensive community engagement program early in the planning process. The program included typical engagement activities such as establishing community action committees, holding public meetings in different segments of the corridor, regular online project updates and providing project information at community events. The Austin program’s success was driven by early engagement that cultivated public interest and ownership and maintained momentum throughout the project.

Engaging stakeholders at multiple levels from the beginning enabled ATP to effectively scope the project, increase public understanding and minimize the project learning curve during NEPA, leading to more efficient and focused input during the formal NEPA review process.

Stakeholder-Informed Planning Reviews

Once the NEPA process begins, delays are not an option. Decisions must be made quickly to keep things moving forward. This requires early buy-in from everyone involved in the review process, along with clearly defined expectations and deadlines.

For Austin, early community engagement established a steady cadence that built consensus throughout the planning process. Internal coordination and document review were strengthened through an approach that prioritized clarity and efficiency. At HDR’s guidance, ATP worked closely with key project partners, including CapMetro and the City of Austin to:

• Develop a well-defined project that curtailed the potential for scope changes during the environmental review
•  Explain the purpose of NEPA and the importance of each reviewer’s input upfront
• Define the appropriate level of design and highlight issues typically addressed during the NEPA phase
• Establish clear review schedules and protocols for HDR-recommended rolling review of chapters prior to submittal to FTA
• Outline next steps following each review cycle

NEPA documents typically rely on 30% design. This can be confusing for reviewers who only occasionally work on NEPA documents and might respond with comments about construction permits or specific project requirements that won’t apply until years later. Without clear upfront guidance, time is wasted addressing comments on elements that are not yet within scope of the current planning effort.

By setting clear expectations for internal review protocols, the team minimized delays often caused by misunderstandings about the NEPA phase and the applicability of feedback. This approach enabled a more efficient review process and helped keep the project on schedule.

NEPA and Informed Consent

NEPA requires federal funds to be used only for public projects that are thoroughly studied, with potential impacts disclosed, alternatives evaluated and meaningful opportunities provided for public involvement in decision-making. At its core, this reflects the principle of informed consent — providing clear, complete information so affected parties can make well-informed decisions. By going through the NEPA process, community members were able to weigh in on how the light rail system would best serve them as well as the project’s aesthetics and design.

The Takeaway: Invest, Align and Integrate

The success of Austin’s light rail EIS demonstrates that speed and rigor in the NEPA process are not mutually exclusive. With strong leadership, early preparation and a commitment to transparency, even the most complex transit EIS projects can advance efficiently while maintaining public trust and meeting the two-year NEPA completion deadline.

Accelerating the NEPA process is not about cutting steps. It’s about doing them smarter — investing early in planning, aligning stakeholders, and integrating engagement and analysis from the outset. Establishing clear expectations, leveraging tools like PEL and maintaining flexibility as projects evolve can significantly reduce timelines without compromising quality or transparency.

As ATP’s NEPA lead, HDR translated these principles into action. Through proactive preparation, disciplined coordination and adaptive problem-solving, HDR supported a streamlined yet thorough review process that met federal requirements. This effort demonstrates a replicable path forward for delivering complex infrastructure projects efficiently, responsibly and with public trust at the forefront
