The Central Valley Floodplain Evaluation and Delineation (CVFED) program is aimed at improving the quality and accuracy of flood hazard data and mapping in California’s Central Valley. Principal objectives of CVFED are:

  • Support risk identification and notification.
  • Prepare floodplain delineation maps to support informed land use planning.
  • Provide hydrology and hydraulics support for preparation of the Central Valley Flood Protection Plan (CVFPP) and associated feasibility studies.
  • Provide information to support project design.

Ford Engineers worked with 4 other consulting firms to analyze the Upper and Lower Sacramento River regions and the Lower San Joaquin River region of the Central Valley and support overall project management. We did the following:

  • Provided input and review of the analysis approach and contractor task orders.
  • Facilitated coordination between contractors and resolved critical issues.
  • Processed topographic and bathymetric data.
  • Established the hydraulic model development strategy.
  • Developed HEC-RAS and FLO-2D hydraulic models of channels and floodplains.
  • Applied the models to estimate 200-yr and 500-yr water surface profiles.
  • Developed informational floodplain maps.
  • Provided technical review.

The results of this project are now being used in the development of the 2017 CVFPP.
