College Lake is a naturally occurring ephemeral water body located along Salsipuedes Creek, a tributary to the Pajaro River in Santa Cruz County, California. In the current condition, the lake is managed so that it is inundated during the rainy season, and then is pumped dry in the early spring so that farming can occur on the lake bed. A number of agencies have expressed … Continue reading College Lake Improvement and Watershed Management Project »

Creek restoration in the Arcade Creek Park Preserve involves creek bank terracing and stabilization and eucalyptus and Himalayan blackberry removal. Re-contouring of creek banks to reduce slopes and application of biotechnical treatments will be implemented to limit future erosion. Replanting of natives will follow eucalyptus and blackberry removal to further stabilize banks as well as enhance habitat. Three priority restoration sites have been identified through … Continue reading Arcade Creek Park Preserve Restoration Project »

cbec has been contracted by the California Department of Fish & Wildlife to assess the feasibility for fish passage barrier construction at multiple sites along Sagehen Creek, CA. The proposed barriers will prevent non-native fishes from recolonizing Sagehen Creek following the eradication of non-natives and the reintroduction of Lahontan cutthroat trout, a state and federally listed species endemic to the Lahontan Basin. Fish passage barrier … Continue reading Feasibility Assessment for Barrier Construction along Sagehen Creek »

cbec was contracted (as a subconsultant to Interfluve) to assist in the design and creation of habitat enhancement features on Dry Creek below Warm Springs Dam in Sonoma County for the benefit of rearing salmonids under an altered hydrologic regime. The Dry Creek Habitat Enhancement Project is intended to ultimately provide six miles of improved rearing habitat, and make up an important component of a … Continue reading Dry Creek Habitat Enhancement Project »

cbec was contracted to develop solutions to enhance aquatic and wetland habitat while also reducing the frequent flooding of Pescadero Creek Road at Butano Creek. The project encompasses portions of the Pescadero Marsh Natural Preserve, managed by California State Parks, as well as the reach of Butano Creek upstream of the Marsh that is privately owned. A number of listed species (e.g. coho salmon, steelhead, … Continue reading Develop Solutions to Enhance Habitat and Reduce Flooding Reduction Along Butano Creek »

While working at the University of Idaho, Boise – Center for Ecohydraulics, Mr. Campbell was principal investigator and researcher in leading a multi-year assessment to quantify the hydroregime of created and natural vernal pools at two established restoration / mitigation sites where created pools have been constructed adjacent to natural pools. The objectives of this study were to identify the hydrologic differences between created and natural … Continue reading Hardpan Vernal Pool Hydrology »

This project is the initial step in the SCRE Habitat Restoration and Enhancement Feasibility Study. The study was developed through the support of the California Department of Fish and Wildlife, the U.S. Fish and Wildlife Service, California State Parks, and the Wishtoyo Foundation’s Ventura Coastkeeper Program. This project was aimed at exploring the feasibility of expanding and enhancing estuarine habitat for steelhead and other native … Continue reading Santa Clara River Estuary Habitat Restoration and Enhancement Feasibility Study »

cbec and H.T. Harvey and Associates (HTH) are performing a multi-disciplinary assessment of the Coon Creek watershed to support the development of the Placer County Conservation Plan, assess anthropogenic disturbances, and develop and prioritize restoration and conservation measures. As part of this project, cbec and HTH are characterizing hydrologic, geomorphic, water quality and ecological conditions in the 112 square mile watershed, starting at the headwaters … Continue reading Coon Creek Watershed Assessment »

The Sacramento Flood control Agency (SAFCA) is undertaking a project to repair nine erosion sites on the Sacramento River east levee. Levee repairs will provide a 200-year level of flood protection while adding ecological value to the riverbank. cbec is providing design assistance that includes coordinating data collection efforts and advising repair designs. We performed field reconnaissance to identify bank erosion sites in need of … Continue reading Sacramento River East Levee Erosion Repair Design Assistance »

cbec is currently developing designs for a restoration project that will reconnect a one mile incised reach of Butano Creek, a tributary to Pescadero Creek, to its adjacent floodplain. The objectives of the restoration are to: Allow for more frequent and longer duration inundation of the floodplain. Increase sediment deposition on the floodplain and reduce the amount of sediment being delivered to downstream areas. Promote … Continue reading Butano Creek Floodplain Reconnection and Restoration Design »
