Reclamation & Erosion Control
Client: RCD of Santa Cruz
A watershed assessment prepared for the East Branch of Soquel Creek identified limiting factors for steelhead and coho production which included high sediment loads, lack of pools, low summer base flows, and high water temperatures. In 2013, the Resource Conservation District of Santa Cruz County contracted with Waterways to prepare a feasibility analysis and engineered designs for biomechanical bank stabilization of a large eroding cutbank and the creation of habitat enhancements along approximately 1,500 feet channel banks that were covered with unvegetated riprap, resulting in lack of habitat complexity or riparian cover.
Client: Kennewick Man, LLC.
The Brookside Apartments are located adjacent to Kelly Creek just upstream of the Kane Drive culvert crossing in Gresham, Oregon. Kelly Creek, which flows through mixed low density residential and commercial areas before flowing into the pond at Mt. Hood Community College, has incised and is prone to lateral erosion and channel widening. This contributed to bank erosion along the right bank of Kelly Creek at the apartment property during high creek stage in 2017. This erosion threatens the stability of an adjacent apartment building.
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.
Client: Resource Conservation District of Santa Cruz County
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.
Client: Sandy Riverfront RV Resort, LLC.
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.
