woodydebris webClient: US Forest Service

Waterways staff led an interdisciplinary team to assess existing conditions within the Blackwood Creek Watershed. Blackwood Creek is a major tributary to Lake Tahoe, drains a mix of steep volcanic and granitic terrain, has a high bedload transport rate, and was historically impacted by grazing, logging, and instream gravel mining. Key impacts identified during the study were excessive bank erosion and channel widening associated with channel incision and loss of floodplain connectivity and the presence of several fish passage barriers. To restore the physical processes that sustain channel morphology and biological function, an aggressive, long-term restoration strategy was proposed.

Side Channel Inlet with Buried Boulder Sill webClient: Wasco County Soil and Water Conservation District

Mill Creek is a moderately-sized tributary to the Columbia River that originates on the eastern slope of Mt. Hood and flows northeast through the City of The Dalles, Oregon. Urbanization along the lower two miles of Mills Creek in the City of The Dalles resulted in the simplification of the aquatic and riparian habitats. In 2011, The Dalles Watershed Council (DWC) commissioned an evaluation of the urbanized reach to assess land use impacts and identify opportunities for habitat restoration. Following the initial assessment, a preliminary engineering design was developed for the Honald/Buyers property. The preliminary design included excavation and connection of a historic side channel that had been partially filled, utilization of an existing side channel as a backwater alcove, installation of a precast spanning bridge across the reconnected side channel, and installation of large wood structures along the channels and floodplain to increase roughness and improve habitat conditions.

A 2007 geomorphic assessment of the Coldstream Canyon watershed identified opportunities to restore stream and watershed function along the lower one-half mile of Cold Creek, extending upstream from the confluence with Donner Creek. Waterways, in coordination with River Run Consulting, prepared final designs for the restoration of this reach.  Designs included inset floodplain bench excavation, re-contouring of steep banks and log/boulder barb installations to reduce bank erosion and expand and improve riparian habitat.  Waterways and River Run also provided permit support and construction oversight.

Client: South Coast Habitat Restoration

Waterways provided design and construction support services to South Coast Habitat Restoration to improve fish passage conditions and vehicular access at a private bridge that crosses Carpinteria Creek. The project site had a concrete-lined channel with drop structures that impeded the upstream migration of salmonids and an undersized bridge that could be overtopped during flood events. Site improvements included removing the concrete-lined channel, recontouring the banks, and revegetating the riparian area. The redesigned channel will provide hydraulic conditions conducive to fish passage. Waterways designed a 55’-span vehicular bridge to replace the undersized bridge. The new bridge can convey floods greater than the 100-year storm event. The construction phase of the project was funded by the Fisheries Restoration Grant Program through the California Department of Fish and Wildlife.

Waterways assisted CWS and DSL in the planning and design of a 20 acre mitigation bank in the Tualatin River Watershed to provide wetland, temperature, and salmon credits.  In addition to providing purchasable credits, the project simultaneously tested a function-based accounting system developed by the Willamette Partnership’s Counting on the Environment program (http://www.willamettepartnership.org). This program was developed with the help of public, private, and non-profit stakeholders to develop a shared accounting system for quantifying impacts and benefits to ecosystem services for application to ecosystem markets. The Partnership completed a test version for water temperature, wetlands, salmonid habitat, and upland prairie that was applied to pilot projects in the program. Half Mile Lane was one of the pilot projects that tested three of these services, and was the only pilot site thus far that resulted in real-world transactions. Therefore, this project tested not only the ecosystem credit calculator, but also the sequence of developing, selling and buying ecosystem credits.

09 029 1Client: Scappoose Bay Watershed Council

In 2000, the Scappoose Bay Watershed Council (SBWC) completed a watershed assessment for the streams and catchments that enter Scappoose Bay. The watershed assessment identified several areas of concern affecting watershed and ecosystem health. Of particular concern was the potential impact that incision has on channel and floodplain interaction and the ability of the stream to support and maintain good aquatic habitat. A 5 mile stretch of South Scappoose Creek that flows through the City of Scappoose was determined to have high priority for further assessment. It was identified as a priority for further assessment due to local concerns about erosion and flooding and the opportunities to enhance conditions for salmon and other organisms.

Waterways staff prepared engineering plans and specifications for stabilization of approximately 100 linear feet of stream bank on Corralitos Creek in Santa Cruz County, California. The bioengineered bank stabilization included fabric encapsulated soil lifts contained within a log revetment structure. Logs were selectively harvested by thinning redwoods from an adjacent grove, thus reducing the cost and environmental impact of the project. Our staff performed construction supervision to ensure successful implementation. Revegetation has been successful and the bank now provides quality habitat in addition to controlling bank erosion and sedimentation in the creek.

pads during constClient: USFS- Lake Tahoe Basin Management Unit

Waterways, in coordination with the USFS Lake Tahoe Basin Management Unit (LTBMU) and Swanson Hydrology, has developed designs to restore the mainstem and tributaries of Cold Creek in the High Meadow Complex (HMC) near South Lake Tahoe, California. The basic restoration objective is to increase soil moisture within approximately 70 acres of meadow area by modifying the morphology and hydrology of the streams in a manner consistent with natural geomorphic processes. Work involves re-constructing approximately 8,700 linear feet of channel and raising the elevation of the streambeds by 2 to 4 feet. The project will significantly increase the diversity and density of meadow wetland vegetation species and shift some areas from seasonally dry and sparse mesic meadows to wet meadow conditions.

The project’s three-year construction plan was completed in 2012, with Waterways providing on-site supervision.
