Environmental Permitting Services

Our environmental permitting team understands permit strategy, environmental compliance, and code requirements.    (NEPA, SEPA, BA, QAPP).  Red Barn has some of the region's leading experts in fish passage design.  We have experts in developing rating matrices on what to next improve or where to invest public funding within a program.  We can provide local jurisdictions with the permitting support they need to get in-water permits on time.  We are knowledgeable about WSDOT risk assessments conducted for projects, and our staff brings 15 years of WSDOT culvert experience.

Our team is here to help public sector clients design and implement a permitting strategy that ensures an expedited process for infrastructure needing replacement.
