Stream Systems

Restore the Stream.
Protect What's Around It.

Streams take a beating. Development, aging infrastructure, and poor drainage turn healthy channels into eroding gullies that undermine roads, wash out banks, and destroy habitat.

We restore them. Our designs stabilize channels using natural patterns and native vegetation rather than concrete and rip-rap. Through careful hydraulic and geomorphic analysis, we create solutions that slow erosion, reconnect streams to their floodplains, and rebuild habitat for fish and wildlife.

Whether we're working in a tight urban corridor or restoring miles of degraded channel for a mitigation bank, the goal is the same: a stable stream that meets regulatory requirements, protects nearby infrastructure, and costs less to maintain over time.

Stream assessment and prioritization
Natural channel design and stabilization
Floodplain reconnection and enhancement
Riparian buffer restoration and native planting
In-stream habitat improvement structures
Bank stabilization using bioengineering techniques
Mitigation planning and crediting support
Regulatory permitting and compliance assistance

We start with the stream itself. Field assessments and hydraulic modeling tell us how it's failing and why. Then we design a solution that fixes the problem without creating new ones downstream.

That means working through the details: permit requirements, property constraints, infrastructure conflicts. We know what regulators need to see and how to get projects approved without endless revisions.

The streams we restore stay fixed. They handle floods, support aquatic life, and require minimal maintenance because they're designed around how water actually moves through the landscape.
