Not only is WSC growing, we made strides to invest in our employees by becoming an employee-owned company with the addition of an Employee Stock Ownership Plan; providing tuition reimbursement to four employees; and supporting the WSC Rocks Committee which plans camping trips, happy hours, and other fun staff events. All the hard work paid off in 2016 as WSC carried a 94 percent retention rate, and was recognized by Inc. Magazine as a Best Places to Work firm.

New hires in order of date hired:

WSC was recently named the construction management consultant for the largest dam removal project in the United States, the $450 million Klamath River Dam Removal Project, which involves the decommissioning of four hydroelectric dams and along a 373-mile stretch of the Klamath River in Southern Oregon and Northern California.

The non-profit Klamath River Renewal Corporation will oversee the project if it is approved by the Federal Energy Regulatory Commission (FERC). Iron Gate Dam, Copco No. 1 Dam, Copco No. 2 Dam, and J.C. Boyle Dam will be decommissioned, and there will be localized river restoration where the dams are deconstructed.

WSC will soon begin providing construction management support during the early stages of the project and throughout the physical removal of the dams, which is expected to begin in 2020.

WSC is a national leader in the field of dam removal and will bring the experience of serving as the program and construction management consultant on the largest dam removal in California, the $83 million Carmel River Reroute and San Clemente Dam Removal and River Restoration Project. That project is in the final closeout period and will serve as a model for future projects as other old dams reach the end of their useful lives and are torn down due to safety and environmental concerns.

The removal of San Clemente Dam, which was owned by California American Water Company, was the culmination of a massive public-private partnership which will result in approximately 25 miles of spawning and rearing habitat for endangered South-Central California Coast Steelhead Trout and improved habitat for threatened California Red-Legged Frogs. WSC will remain the construction management consultant during a 10-year period of monitoring and habitat establishment, which is already underway.

San Clemente Dam was removed in December 2015 and work continued into 2016 when the Old Carmel River Dam was removed and a stretch of the Carmel River was restored. Other key milestones in 2016 included : The removal of Sleepy Hollow Ford low water crossing and the construction its replacement, the 150-foot Sleepy Hollow Bridge; demolition of the Carmel Valley Filter Plant, water tanks, chlorine storage plant, and Dam Keeper’s House; and the completion of the Tularcitos High Road Access Route.

California American Water Company will donate 925 acres of land to the U.S. Bureau of Land Management for public use after the development of a long-term management plan.

Every year ending in five or zero, California water providers are required to prepare Urban Water Management Plans (UWMPs) to enable long-term resource planning and project existing and future water demands. Water suppliers that either provide over 3,000 acre feet of water per year or serve more than 3,000 urban connections are required to submit a UWMP to California’s Department of Water Resources (DWR). Each UWMP evaluates supply, supply reliability, demand, demand management measures, supply and demand comparisons, recycled water, and optionally climate change impacts, for the next 20 years. For more information, see DWR’s website.

In the preparation of their Guidebook for the 2015 UWMPs, DWR called on WSC to contribute as part of their Guidebook Advisory Committee and through support in developing energy intensity calculation methodologies.  WSC has leveraged this insight and knowledge to bring value-added services to all of our clients, as well as confirm that each submitted UWMP will be accepted by DWR.

For the 2015 round, WSC will be submitting 17 UWMPs for various districts across California in July. WSC has been hired by the Cities of Arroyo Grande, Victorville, Riverside, Pismo Beach, Lompoc, and Camarillo, California American Water Company (Sacramento, Monterey, Ventura, Los Angeles and San Diego Districts), Soquel Creek Water District, San Lorenzo Valley Water District, Rincon Del Diablo Municipal Water District, and Big Bear City Community Services District. Additionally, WSC will be completing a Regional Urban Water Management Plan (RUWMP) for the San Bernardino Valley Municipal Water District. This RUWMP will consist of ten individual agencies whom will have a chapter dedicated to addressing their approach to meeting their individual agency requirements for normal, single dry year and multiple dry year scenarios.

For the 2005 and 2010 round, WSC submitted 13 UWMPs, all deemed completed and accepted by DWR without the need of revisions.  WSC will continue to coordinate with DWR staff to ensure each agency’s 2015 UWMP is deemed complete, and is confident that all UWMPs will be accepted by DWR without the need for revisions.

Submitted 2010 UWMPs are available on DWR’s website, as well as summaries of 2010 UWMP Data.

WSC's 2015 UWMPs

Nearly six years ago, WSC began working with California American Water Company (California American Water), the California State Coastal Conservancy, the National Marine Fisheries Service, and several project stakeholders on the removal of the San Clemente Dam and restoration of the Carmel River. At the time of project inception, the San Clemente Dam was over 90 years old and nearly 95% filled with sediment, causing the San Clemente Dam to be deemed seismically unsafe by the California Division of Safety of Dams. In addition to reaching the end if its useful life, the San Clemente Dam posed several environmental concerns, including negative impacts to native species like the South-Central California Coast Steelhead Trout (Steelhead) and the California Red-Legged Frog. After thorough analysis, the Project Team concluded that the dam was to be removed in efforts to improve fish passage, repopulate native species of plants and animals, and ensure the safety of the local community. As a unique approach, the $83 million project was jointly funded by public and private parties, including California American Water, the California Coastal Conservancy, and the National Marine Fisheries Service, among others.

As of December 2015, the San Clemente Dam was completely removed and the Carmel River began flowing along its new course, including 56 carefully engineered resting pools for the spawning Steelhead.  The completion of this project has spurred the efforts to study and remove dams throughout the country. More information about the project and the conversation it has spurred can be found in the San Francisco Chronicle’s Article about the project.

By early February 2016, an adult Steelhead was spotted migrating upstream into the new Carmel River. Redds, or nests that female Steelhead build for their eggs, have also been seen past the original site of the San Clemente Dam, showing unprecedented progress. Fish experts predict that the number of migrating Steelhead could more than double in its first year.  To learn more about the potential effects on the Steelhead and future action to be taken to aide their recovery, take a look at the Monterey Herald’s article.

The project site was filmed throughout the construction period and is continuing to be streamed live on the web to show changes with the seasons and water flow.  California American Water has created a series of videos on the progress of the dam removal. The first segment, New Life for the Carmel River, provides a visual background on the San Clemente Dam in relation to its original state and the future of the project. The second segment, San Clemente Dam Removal Update – Year 2, shows the progress made on the dam removal from the beginning of construction to the end of the second year of construction. The third and last segment, San Clemente Dam Removal Update – Year 3, features the final stages of the removal of the dam and construction of the new 25 mile section of the Carmel River, as well as the intended impact of this project on the local community and environment.

Final tasks are being addressed and the project is scheduled to be completed by Spring 2016.  Following project completion and an observation period, California American Water will donate the surrounding land to the US Department of the Interior’s Bureau of Land Management for public ownership into perpetuity.

The removal of the San Clemente Dam and the re-routing and restoration of the Carmel River marks the largest dam removal project in California’s history, and is precedent-setting for future dam removals nationally, and worldwide.  Like the San Clemente Dam, numerous dams all over the country are at risk of sediment build-up and structural instability, and ultimately reaching the end of their useful life.  The knowledge and insight gained throughout this project will be utilized to address this growing concern.  Additional details regarding the impact of aging dams and steps being taken to remove dams throughout the country can be found in the Engineering News-Record’s article.

WSC is thrilled to have been the Project and Construction Manager for this project for the last six years, and our team looks to build on the success of this project, bringing innovation, experience and leadership to address complex challenges throughout the water industry.
