Transportation Planning Support

ENPLAN provides environmental services for transportation improvement projects throughout northern California. Our multidisciplinary team of seasoned professionals can provide full environmental compliance for a broad range of transportation improvement projects. We offer particular expertise in conducting environmental studies and documentation for Caltrans “Local Assistance” projects. Given our extensive experience over the past 30 years, we are very familiar with regulatory agency personnel and procedures.

We are known for completion of succinct and accurate reports that meet local, state, and federal agency standards, and have successfully completed environmental studies for over 75 Caltrans/FHWA-funded projects.
