FDG is celebrating 20 years of serving our communities!
We would like to take this moment to thank all of our customers we have worked with over the last 20 years. Our client relationships are what drives our firm to continue to expand and improve so we can continue to provide cost-effective and reliable engineering designs. In our 20 years Firwood Design has accomplished an extensive variety of projects ranging from street improvements, industrial site improvements, utility infrastructure upgrades, public park enhancements , stream stabilization projects to fish ladders to name a few. Without our marvelous staff, we would have not been able to accomplish our successful projects.
We are looking forward to continuing to provide reliable engineering designs for the communities around us.

Reliable Design to the Smallest Detail

With years of finding creative solutions that comply with a variety of permitting and regulatory needs, our engineers thrive at bringing your environmental and civil projects to life and overcoming unexpected obstacles. We serve individuals, companies, and communities across Oregon, Washington, Idaho, and Montana, prioritizing helpful collaboration with all stakeholders and always charging an equitable rate.

“… we are very impressed with the excellent service we are receiving from FDG. From the friendliness on the phone every time we speak to you, to the Application Checklist that Kelli recently sent that lets us know where we are in the process… we feel we are being represented by true professionals.”

— Alfred Bookman, Vancouver Washington Resident

“I have a long history of working with Kelli and Firwood Design. What I like best about working with Firwood is that they are local. That means we have easier access to them than someone outside our community. They are always there to answer any questions that we have. It also means that they have more knowledge about the community compared to a firm from outside the state. I can’t compare them to anyone else! “

— Ulla Brunette – District Secretary, Government Camp Sanitary District

“I have been working through Kelli Grover and her company Firwood Design Group for going on 9 years, and all the projects I have had Firwood involved in have been fantastic. They come through every time with great work and satisfy the requirements the county or city needs to complete the land use applications.”

— Dale Burkholder – Principal Real Estate Broker
