Construction

Fish Barrier Removal

We remove culverts that are impassible barriers to fish migration and replace those barriers with fish passable culverts or, in some cases with bridges.

Beaver Management

In cases where beaver activity is problematic, we will install “beaver deceivers” that level ponds upstream from beaver dams. In addition, we teach our clients other techniques on “how to live with beavers.”

Stream-bank Protection and Enhancement

Using “bio-engineered” techniques, we restore and enhance stream-banks reducing erosion and sedimentation while at the same time enhancing fish and wildlife habitat.

Log/Stump Fish Habitat Installation

One of the activities that we enjoy is the design and construction of fish and wildlife habitat structures from logs and stumps that result in habitat that would make Mother Nature proud.

Stream Channel Relocation

Unfortunately, sections of many streams have been placed in pipes preventing migration of fish…we design and construct new stream channels that result in streams seeing daylight again.

Fish Ladder Construction

Often culverts under roads are perched above streams below resulting in barriers to fish migration. The best solution to this circumstance is to excavate the barrier culvert and replace it with a fish passable culvert. However, this action necessitates removal of the overlying road. Often that action is not possible due to costs. In these situations, we design and construct fish ladders. Our most recent design is the winner of the
National Fish and Wildlife Foundations 2006 Radical Salmon Design Contest.

Wetland Enhancement/Restoration

Three factors determine the presence or absence of wetlands: Hydrophytic Vegetation (moisture loving plants), Hydric Soils (soils that are often wet) , and Wetland Hydrology (sufficient water for wetland plants during the growing season). So far, we have restored three-acres of wetlands from a parking lot that used to be a wetland, restored five-acres of wetland that were part of a golf course, and created a 1/4-acre riparian wetland next to a stream.

Stream De-watering and De-fishing

In advance of the installation of in-stream fish habitat structures or cleaning out culverts where streams pass under roads, it is generally a requirement of permitting agencies that the work area be “de-fished” and “de-watered” in advance. We have extensive experience tackling this challenge in a wide variety of circumstances.
