Arroyo Simi Channel Improvements
Owner: Ventura County Watershed Protection District
Location: Simi Valley, CA
Value: $6.3 Million
Year: 2007 – 2008
The objective of the project was to increase the capacity of the flood control channel and culvert to contain a 100-year flood event providing protection to the adjacent residential properties.
The project required replacing the existing 34′ wide trapezoidal channel with a 42′ wide rectangular channel running through a residential neighborhood with very limited right of way. The existing channel lining was completely removed and replaced with a reinforced concrete channel.
