The Technical Advisory Committee (TAC) was established to provide scientific and technical oversight for the Cache Creek Resources Management Plan (CCRMP) and the Cache Creek Improvement Program (CCIP).  The TAC collects and analyzes data, identifies maintenance needs and priorities, and provides critical review of the design and construction of improvement projects.  The TAC also works with a variety of local stakeholders in making recommendations regarding management of the riparian area. There are three to four TAC meetings a year, which are held "ad hoc" and are open to the public. More information regarding the TAC and TAC meetings can be found below.

The three subject matter experts who currently serve on the Cache Creek Technical Advisory Committee are:

Mark Tompkins, P.E., Ph.D. - TAC Geomorphologist & TAC Chair

Dr. Tompkins completed his undergraduate and Master’s degrees from the University of Illinois and earned his Ph.D. in Environmental Planning from University of California, Berkeley.  He is a registered Civil Engineer and has over 20 years of consulting experience in fluvial geomorphology, river restoration, flood management, hydrology, hydraulics, sediment transport, fisheries biology, environmental planning, and water resources engineering.

Paul Frank, P.E., CED - TAC Hydraulic Engineer

Mr. Frank is an ecological engineer experienced in river corridor, wetland, and watershed management planning, analysis, and implementation.  He has 17 years of engineering consulting experience practicing hydraulic, hydrologic, and flood analysis and modeling; fish passage design; sediment transport and fluvial geomorphology; and ecosystem conservation, restoration, and assessment planning. Mr. Frank has experience with designing and constructing multi-objective river and wetland design projects in North America, Europe, Asia, and the Middle East.  He is a state-wide recognized expert in hydraulic and sediment transport analysis and modeling, having developed models for hundreds of miles of river systems throughout California.

Andrew Rayburn, Ph.D - TAC Riparian Biologist

Dr. Rayburn obtained a B.A. in Biology from Austin College, a M.S. in Ecology and Evolutionary Biology from Iowa State University, and a Ph.D. in Ecology from Utah State University. He is a Certified Ecologist (Ecological Society of America) and a Certified Ecological Restoration Practitioner (Society of Ecological Restoration with 19 years of experience in applied ecology with a focus on ecological restoration, invasive species control, landscape assessment, geospatial analysis, and both riparian and upland ecosystems.
