We Deliver Environmental Compliance with Expertise and Efficiency

Mark Thomas provides environmental compliance services for a wide variety of transportation projects, with proven experience preparing CEQA and NEPA documentation that meets agency expectations, stands up to legal scrutiny, and meets all regulatory requirements. Our focus is on implementation – we’re driven by helping projects succeed and getting shovels in the ground. To that end, we bring proactive and streamlined strategies to every project, identifying the most straightforward pathway to environmental clearance without sacrificing defensibility or technical expertise. We facilitate the key conversations that set projects on the right pathway – or get them back on track when help is needed.

Our team is fluent in Caltrans Local Assistance processes and the Standard Environmental Reference (SER), helping clients produce complete, review-ready deliverables and move efficiently from concept to approval. We maintain strong working relationships with key environmental and permitting agencies, supporting clear communication, streamlined reviews, and timely resolutions to comments.

Because our environmental services integrate seamlessly with planning and engineering, we help teams anticipate environmental constraints early, reduce schedule risk, and keep projects advancing. without surprises or avoidable delays.
