stable stream channel alignment
steps and pool construction
stream classification
two-stage channel design
urban streams
water quality

Rootwads (Large Woody Debris)
We've installed almost a thousand. We've learned where they will work and where they won't. We are assessing many of our projects and documenting the benefit of rootwads as refuge for fish.

Step Pools are great solutions for highly entrenched, high gradient stream channels. The construction of steps and pools can also provide grade and energy controls at culvert outlets.

Soil Bio-Engineering and Vegetation
From steep slopes to river banks, we've learned a lot from our more-than-40 projects that have a true soil bio-engineering component and from the handful of professionals with more field experience than we have. We have also learned, as with other buzz-word terms, that 'soil bio-engineering' is commonly used inappropriately by many consultants.

Where we have used massive quantities of vegetation to reinforce the soil mantel and create a living system are the projects we consider to have a soil bio-engineering emphasis. Not all or our restoration projects required that emphasis and many are constructed in a season that does not support that technique.

Nevertheless, all or our projects emphasize soils and vegetation as a major component of the restoration process. We go to great lengths to better understand plant development by measuring and controlling soil compaction, by lab analysis of soils and compost, by collecting light and photosynthetic data.

We pride ourselves in the density and diversity of native plants that develop on our projects. We enjoy salvage harvesting of native plants and can offer certified nursery stock.

Public Involvement
The public loves to be a part of our projects, to be a part of the restoration process, to be part of a healing process.

Natural Channel Design
Within the larger channel that accommodates tile outlets and conveyance is a smaller channel that supports the ecosystem during the low flow periods that are the most stressful for aquatic organisms.

Riffles and Pool Sequences
Riffles are the life blood of the stream. The riffle area is a natural grade control that accelerates the water column producing a variety of flow velocities (critical and supercritical) which oxygenate the stream and volatilize pollutants. This provides the fast currents and clean substrates that are essential for the colonization of bacteria, periphyton, macro-invertebrates and spawning beds for fish. That acceleration of flows also creates the pools or deep water areas that are essential for sustaining fisheries during low flows. This creates a vertical sinuosity that is predictable (the riffle, run, pool sequence) and manages energy within the channel. That energy component is important to the streams ability in efficiently transporting sediment and bed materials downstream. Constructing riffles and runs in degraded channels restores the variety of flow velocities and micro pools necessary to support aquatic ecosystems.
