Waterways performs annual cross section surveys at seventeen permanent monitoring sections established along the San Lorenzo River, from Highway 1 to the river mouth.   This project assists the City of Santa Cruz in meeting flood protection requirements and habitat restoration goals by quantifying changes in channel elevation, form, and vegetation cover.  The monitoring data is presented in an annual report discussing the geomorphic and hydrologic trends, and providing adaptive management recommendations to the City’s riparian vegetation and sediment management operations.

Waterways provided geomorphic assessment, land surveying, and engineering design services for ecological enhancements to a degraded reach of Sycamore Creek, at the confluence with Uvas Creek. The design included recontouring channel banks and the creation of inset floodplain benches to reduce erosion. Native vegetation was established on graded areas. Hydraulic control structures installed at the project included periodic boulder weirs and stilling pools for energy dissipation and a sheetpile cutoff at the project terminus. The detailed grading plan allowed for the retention of mature riparian trees within the project footprint.

Waterways staff assisted Granite Construction Company with planning, design, and permitting of a proposed off-channel gravel extraction project on the Kunzler Ranch property, located at the confluence of Ackerman Creek and the Russian River, in the Ukiah Valley of Mendocino County. Waterways has conducted hydrologic, hydraulic, and geomorphic analyses to assess flooding impacts, habitat development potential, and channel stability at the proposed project site, under both project-life and reclamation phases.

Waterways staff worked with the City of St. Helena and a team of consultants to design, permit, and construct a multi-objective flood control project that provides 100-year flood protection for residential properties along the Napa River, restores important floodplain and aquatic habitat, and improves public access.  Specific elements of the project include a geomorphically-based floodplain terrace, shoreline restoration involving removal of an existing gabion and rip-rap bank protection structures and replacement with a natural point bar shoreline configuration, bioengineered bank stabilization structures, FEMA certified levee setbacks and floodwall construction, relocation of homes from the floodplain, and approximately 2,500 ft of pedestrian trails with interpretive signage.

The Town of Truckee has partnered with the Truckee River Watershed Council and Truckee Development Corporation in a multi-objective redevelopment project that seeks to revitalize the downtown and the adjacent rail yard, reduce flood risks for businesses and residents, and improve the natural environment. The focus of this project is restoration of Trout Creek and development of open space that connects residents and visitors of the Truckee area to important natural resources. Waterways is leading a team of consultants tasked with enhancing habitat values and functions of Trout Creek.

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.

Independence Lake holds one of only two known wild, self-sustaining populations of Lahontan cutthroat trout in the world - a species that has been lost from 99% of its historic range.  Waterways staff are proud to have assisted The Nature Conservancy in their efforts to protect and restore this critical habitat through the planning and design of a barrier to exclude non-native fish from the lake. 

PA210029webClient: Necanicum River Watershed Council


Waterways was hired to develop an engineered solution to address a high priority fish passage site on the South Fork Necanicum.  The project site consists of a 6-foot high diversion dam and intake structure.  The objectives of the project were to provide unimpeded passage for all species and life histories of salmonids present in the South Fork, meet NMFS and NOAA Fisheries fish screening guidelines, and provide a reliable source of water to the City of Seaside according to their existing water right.  Specific project tasks include preparing a set of alternatives for review by a technical advisory team, preparation of preliminary engineering drawings for the selected alternative, preparation of a water management plan that identifies potential changes in the operation and management of the diversion as a result of the modifications, and preparation of the final engineering drawings.
