Environmental permitting can be complex and time-consuming. Our team makes the process straightforward by helping clients navigate local, state, and federal environmental regulations with confidence and accuracy. From wetland delineations and critical area reports to Clean Water Act and NEPA compliance, we keep your project on schedule and in compliance. We work directly with regulatory agencies to anticipate challenges before they become delays, ensuring your permits are complete, defensible, and approved as efficiently as possible.

Our permitting program is led by a Senior Wetland Scientist and Professional Wetland Scientist (PWS), and Aaron Gibson, a seasoned environmental compliance specialist with extensive experience across Oregon and Washington. Their experience in wetland science and regulatory policy makes for one of the most trusted names in permitting throughout the region. They bring technical precision, agency insight, and real-world experience to every project. When clients receive letters from regulatory agencies or need guidance on complex environmental approvals, clients call ERSM to get things resolved quickly, correctly, and with integrity.
