Confluence prioritizes three core values: client service, staff support and satisfaction, and consistent delivery of quality work. We believe empowering employees to pursue their passions is key to supporting these three pillars.

Our team includes fish and wetland scientists, built and natural environment planners, regulatory and permitting specialists, and GIS and remote sensing experts. We ensure that each project is staffed with an outstanding team that can successfully deliver strategic solutions. Read more about our services here.

Our mission: To improve our community through effective and efficient solutions to our clients’ complex needs, while fostering a positive work place of innovation and opportunity.

For over 10 years Confluence’s Eric Doyle has been working with the Confederated Tribes of the Colville Reservation to develop EDT model platforms for multiple subbasins.

September – The State of Louisiana reached another major milestone to bring the Mid-Barataria Sediment Diversion project one step closer to construction. The Army Corps of Engineers released on September 19 the final environmental impact statement for the $2 billion project, which will fight land loss by diverting water and sediment from the Mississippi River into Barataria Basin. Permits could be obtained as early as December, to put the project on track to begin construction in early 2023. Kudos to the state leadership and Coastal Protection and Restoration Authority for guiding this project. Confluence is honored to be part of the project team.
