ULDC Certification

The Urban Levee Design Criteria (ULDC) provides engineering criteria and guidance for the design, evaluation, operation, and maintenance of levees and floodwalls that provide an urban level of flood protection (i.e., 200-year level of flood protection) in California, as well as for determining design water surface elevations (DWSE) along leveed and unleveed streams.

We provide assistance for agencies subject to meeting the ULDC requirements. This support includes:

  • Evaluation and application of the ULDC criteria
  • Reporting on adequate progress
  • ULDC certification
