We offer a variety of planning, survey, design, permitting, and construction support services to meet each of our client’s unique goals. Our aim is to combine the right blend of ecology and engineering and to provide successful solutions to modern environmental challenges that promote the wise stewardship of our natural environment.
Stream Restoration and Channel Design
Our channel designs balance habitat with stability and aesthetics to produce streams that look and function as though created by nature.
Confluence restores streams and rivers through a process-based design procedure that relies on a thorough understanding of the project vision, clear and concise goals, quantifiable objectives that support the project’s goals, and design criteria that justify each element. Whenever possible, we encourage post-project monitoring to measure the project’s success over time. This process has proven effective on our most challenging projects involving multiple stakeholders and landowners. In addition to restoring streams to improve fish and wildlife habitat, we have designed over a dozen stream remediation, relocation, and stabilization projects involving contaminated stream beds and floodplains.

We provide comprehensive wetland services, including delineation, monitoring, and mitigation planning and design.
Confluence’s wetland scientists combine their expertise in hydrology, soils, and botany to map, monitor, and restore wetland habitats. We understand the importance of protecting these fragile and vital components of the landscape and work hard with our clients to avoid or minimize wetland losses to development and effectively mitigate losses deemed unavoidable.

Water Resource Engineering
Our staff of Civil and Water Resource engineers are experienced in designing a variety of ecologically-sound and flood-resistant structures that provide benefits to fish and wildlife while improving our quality of life.
Our engineering team begins by understanding our client’s vision, followed by developing clear and concise goals, identifying all constraints that may factor into achieving those goals, and utilizing defensible design criteria to justify our designs. Nearly all of Confluence’s projects require close collaboration between our engineering and ecological staff, allowing us to generate solutions that are technically and scientifically sound.
