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.
