Indiana Insights: What Are NEPA Assessments?

Delays Don’t Always Happen In The Field!

If your project involves federal funding, NEPA is often part of the path forward. While environmental assessments can feel complex and overwhelming, they keep projects moving when done correctly.

NEPA assessments evaluate a project’s potential effects on the surrounding wildlife, environment, and cultural resources. Some of the factors that are evaluated and could affect the project design include:
• Air quality, noise, and flammable and explosive hazards;
• Wetlands, floodplains, and natural resources;
• Historic preservation and community impacts; and
• Contamination, hazardous materials, and site history.

Each factor must be evaluated for potential effects, documented for compliance, and coordinated with agencies before a project can move forward. That’s why timing matters.
When environmental reviews start early:
• Projects stay aligned with funding requirements,
• Agency coordination goes smoother, and
• Risks are identified before they become delays.

If environmental assessments are delayed:
• Approvals get held up,
• Funding can be at risk, and
• Schedules can slip, preventing closing on financing and delaying the start of construction.

NEPA isn’t just a box to check. It’s about responsible design, protecting the environment, and supporting healthier communities. SME can help guide teams through the process, coordinate with agencies, and keep projects moving forward with confidence.
