Matilija Dam meetings February 2020

On February 11, 2020 two meetings were held to update stakeholders on progress being made on the Matilija Dam Ecosystem Restoration Project.  Technical studies have been underway since 2018 with support from a $3.3 million grant from the California Department of Fish and Wildlife.

As the earlier studies suggest, removal of the dam and release of the impounded sediment has implications for much of the infrastructure downstream including bridges, levels, and water supply components.  The current work has been focused on the feasibility of the new dam removal method, analyzing the sediment transport, and re-evaluating the downstream infrastructure needs.

The Technical Stakeholder Group met from 12:30 pm to 4:30 pm at Ventura County's Saticoy Operations Yard.  The agenda was filled with technical presentations from the project consultants:

1. Welcome and Introductions – WPD – Peter Sheydayi
2. Dam Removal Contract - AECOM and Stillwater Sciences
      a. Field Investigations
      b. Dam Structural Evaluations
      c. Sediment and Hydraulic Analysis
      d. Predictability of Flushing Event
      e. Re-evaluation of downstream Project Components and Real Estate Plan
      f. Short-term Water Supply Mitigation Alternatives Refinement
      g. Long-term Water Supply Mitigation Alternatives Refinement (Robles)

6. Coastal Sediment Studies – Integral
7. CEQA Update and Permit Plan – Aspen
