The Resource Conservation District of Santa Cruz County (RCD) retained Waterways to prepare a sediment source analysis and action plan for the recently acquired Geyer Quarry property. The Land Trust of Santa Cruz County purchased the property in 2008 to provide protection to a portion of the unique and delicate Sandhill ecosystem that extends from the Bonny Doon through the Scotts Valley area of the Santa Cruz Mountains. Mining activity, road construction, logging, and off‐highway vehicle (OHV) use have exposed steep, denuded hillslopes in many locations throughout the parcel. These eroded areas deliver excessive volumes of sediment to the San Lorenzo River and its key tributaries (in this case Bean Creek and Zayante Creek). The large sediment inputs to the tributary channels negatively impact salmonid habitat.

Waterways Consulting has provided planning, design, and construction implementation support (e.g., staking, field modifications, and supervision) for the installation of 3 ponds located on the Watsonville Slough Farm property, owned by the Land Trust of Santa Cruz County. The ponds were created either as a stormwater or sediment control facility or for habitat enhancement.

 

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 excavating an inset floodplain bench, re-contouring steep banks, and installing log/boulder barb to reduce bank erosion and expand and improve riparian habitat. Waterways and River Run also provided permit support and construction observation.

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 construction observation.

Waterways recently provided planning, design and construction management services for Phase 1 of the Arroyo Burro Open Space Restoration Project. The project area is located within the Arroyo Burro Open Space Preserve, owned by the City of Santa Barbara. Pre-project conditions within the approximately 20 acre project area were characterized by a deeply incised channel with actively eroding banks that was disconnected from historic floodplains. Ongoing bank erosion threatened to undermine a section of Las Positas Drive and several large oak and sycamore trees. Exotic vegetation had colonized the former floodplains and streambanks.

American Rivers performed an assessment of Alpine Meadows in the Carson River watershed, and identified Faith Valley as its highest priority meadow restoration due to its impairments and its popularity with recreational users for fishing, hiking, and camping. American Rivers hired Waterways to complete a baseline conditions assessment and develop designs for habitat improvement. The baseline assessment included topographic survey, modeling, geomorphic mapping, botanical and other assessments. The assessment determined that the primary cause of impairment in Faith Valley is channel incision and associated detrimental impacts, including bank erosion, lowered groundwater table, and degradation of meadow plant assemblages.

This “Working Lands” project balances habitat improvement with improving or maintaining existing agricultural uses in a 300-acre sheep and cattle ranch on the tidal floodplain along the Coquille River in coastal Oregon. Conversion to pastureland at the site began in the early 1900s with the clearing of native forest, construction of levees and linear drainage ditches, and installation of tidegates, which were in disrepair and prevented active tidal flows and fish access to critical vegetated floodplain habitat. Waterways was contracted by the US Fish and Wildlife Service and the Coquille Watershed Association to support USFWS, ODFW, and the Coquille Watershed Association to design, permit, and implement the project. The project area is privately owned by a local family and will continue to function as a ranching operation following project completion. The project involves excavating new tidal channels, filling drainage ditches, installing large wood, re-establishing fish access to the floodplain, and building two large concrete box culverts with muted tidal regulator (MTR) controlled tide gates to allow managed tidal flows.

Mill Creek is the largest tributary of San Vicente Creek, in Santa Cruz County, an important stream for steelhead and coho salmon on the central California coast. Mill Creek drains a small, steep watershed containing a localized area of granitic rocks within the highly erosive marine sediments that dominate the Coast Range. Because of this, Mill Creek is an important source of resistant spawning gravel, which is limiting for fish in many watersheds in the central Coast Range. Within the recently-acquired San Vicente Redwoods Preserve, two dams on lower Mill Creek impound gravel and prevent fish passage.

Clackamas County Water Environment Services (WES) is one of the agencies responsible for wastewater and stormwater management in the greater Portland metro area. To better understand the effects of management activities on watershed health and the status of aquatic resources in the district, WES contracted with Waterways to develop monitoring methods and carry out monitoring of aquatic resource and physical habitat conditions in its management region, which consists of small and medium sized tributaries in the lower Willamette, Clackamas, and Tualatin Rivers, in northern Clackamas County, OR. In close cooperation with WES, Waterways led the development of geomorphic monitoring approaches, site selection, establishment of monumented cross sections and initial monitoring of 25 to 30 stream reaches in 2009. Each monitoring event includes long profile and cross section surveys, bulk bed material sampling, pebble counts, large wood inventory, measurements of pool size and frequency, documentation of active bank erosion, and general geomorphic observations. These data are complimented with macroinvertebrate population analysis of the same reaches by Mike Cole (Cole Ecological), a regional expert in stream macroinvertebrates. WES retained Waterways to lead monitoring events in 2009, 2011, 2014, and 2017.

Waterways staff developed a restoration plan for an area in the Watsonville Slough near Ramsay Park. Initial assessment of the Project Area identified an old landfill adjacent to Ramsay Park as a high priority site to restore wetland habitat and provide for public access. The Ramsay Park site was part of a larger restoration planning process that identified and prioritized a range of sites in the area (including the landfill site). A complete restoration plan for the Ramsay Park was developed that included removal of fill, restoration of wetland and upland habitat, and public access trail and signage. Waterways’ tasks included hydrologic and ecological assessments, a biotic report, wetland delineation, engineering plans, and a design report. The design aimed to create a wetland setting with irregular shorelines, suitable vegetation and natural wetland features that would serve to restore and enhance wildlife habitat and wetland functions on site.

RodriguezClient: County of San Luis Obispo

Waterways was contracted by the County of San Luis Obispo Public Works Department (Utilities Division) to provide assessment, design and construction observation services for the improvement of fish passage conditions and the protection of a waterline in Arroyo Grande Creek at the Rodriguez Bridge crossing. Our work also included preparation of a design report and response to comments from NMFS fish passage engineers.

Just upstream of Rodriguez Bridge there was an exposed concrete encased water supply line within the bed of Arroyo Grande. Channel scour on the downstream side of the encasement had nearly undermined the encasement, potentially leading to structural failure of the pipeline, and leaving a 3 foot hydraulic drop that created a partial barrier to fish passage.

In 2000, the Scappoose Bay Watershed Council (SBWC) completed a watershed assessment for the streams 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 five mile stretch of South Scappoose Creek that flows through the City of Scappoose was determined to be a high priority reach 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.

The Sandy River RV Resort (Resort) is located just upstream of the confluence of Beaver Creek and the Sandy River in the City of Troutdale. Beaver Creek, which flows through mixed low density residential and commercial areas with multiple road crossings before flowing into the Sandy River, is prone to lateral erosion and channel widening. This contributed to bank erosion along the right bank of Beaver Creek at two sites on the Resort property during high creek stage in 2017. This erosion threatened the Resort infrastructure in addition to being a source of sedimentation to the stream which impacts threatened aquatic species and their habitat.
