Follow on Google News | Lessons learned from the Saint Francis Dam Disaster help prepare Ventura County Public Works AgencyBy: Consortium Media Almost 100 years later, Ventura County (VC) is still no stranger to flooding. Ventura County was declared a federal flood disaster area following the winter storms in late 2022 and early 2023. Since then, Southern California experienced the anomaly of being caught in the path of a tropical storm and unusual summer rain; it is probable that Ventura County may face another bout of heavy rain and flooding this coming winter. To prepare residents, the Ventura County Public Works Agency (VCPWA) just launched https://vcfloodinfo.org/ This website has many helpful resources to inform, educate, and prepare both local and non-local residents affected by flooding. Real-time storm data is linked from this to the VC Flood Warning System, allowing residents and first responders, such as Ventura County's Fire Department, to know the status of flooding in specific areas; this includes detailed instructions on how to set up the flood warning system on mobile devices, flood zone hazard-mapping, and the latest weather news. Additionally, sandbag information, flood insurance, FEMA floodplain mapping, elevation certificates, property protection suggestions, and more are available in multiple languages. The most significant dam the County of Ventura owns is the 168-ft-tall Matilija Dam in the Ventura River watershed on Matilija Creek north of Ojai. There has been extensive support for the dam's removal. Constructed in 1948, the dam's main purpose was to create a water supply reservoir. However, over several decades, the reservoir became filled with sediment and is no longer needed as Lake Casitas provides that needed water supply. Out of the original capacity of 7,000 acre-feet, only approximately 100-acre feet capacity remains behind Matilija Dam. The Matilija Dam Ecosystem Restoration Project is immense in terms of planning, cost, and size. It has been estimated it will cost $230 million to modernize downstream infrastructure. This includes flood protection, water supply reliability, community climate resilience, renewing access to prime spawning and rearing habitat in the Matilija Creek headwaters for the federally endangered southern California steelhead, and restoring natural sediment transport and ecosystem function to enhance floodplain, riparian, and near-shore coastal habitats. VCPWA has been working on this initiative since 1999 and in 2022, completed a new Santa Ana Bridge in Oak View as part of modernized infrastructure needed before dam removal. End
