Surfers' Point Update Spring 2019



Final Design moves forward:

On May 6, 2019, the City of Ventura approved a cooperative agreement with BEACON to contract with the consultant for final design and engineering of Phase 2 of the Surfers’ Point Managed Shoreline Retreat project.   BEACON approved the final agreement at their May 17 board meeting. This clears the way for work to begin under the $335,000 grant announced by the Ocean Protection Council last summer.

Phase 2 of the project will relocate the damaged bike path and parking lot back to Shoreline Drive as shown in this illustration:

Stewardship events:

Volunteers continue to help maintain the dunes at Surfers' Point.  The primary focus has been removing non-native "Sea Rocket" plants in the springtime before a new crop of seeds has set.  This strategy has been effective, as each year the quantity of this invasive plant is reduced.

In 2019,  Surfrider organized two Spring Dune Stewardship Workdays, held on March 10 and May 5.  Surfrider volunteers have been maintaining the restoration area by removing non-native weeds since 2011. Our work is paying off, and the dunes are looking great!

Santa Ana Bridge replacement awarded $13.4M grant


On May 13, the California Department of Fish and Wildlife announced a $13,426,938 funding award to Ventura County Watershed Protection District for the Santa Ana Bridge Replacement - a component of the Matilija Dam Ecosystem Restoration Project.  This is one of 38 projects statewide totaling $48.5 million to receive funding for multi-benefit ecosystem restoration and protection projects under its Proposition 1 and Proposition 68 grant programs.



The Santa Ana Bridge Project is the first major component of the Matilija Dam Ecosystem Restoration Project, which will remove the obsolete dam to restore habitat for the endangered Southern steelhead while allowing for natural transport of sand and cobble to Ventura County’s eroding beaches.   Dam removal will take advantage of high river flows to naturally remove the accumulated sediment that has rendered Matilija Dam obsolete. These renewed flows necessitate a number of downstream infrastructure components that must be completed prior to dam removal, including upgrades to flood control and water supply facilities, as well as the replacement of two bridges.  


The grant will fund replacement of the existing 210-foot long Santa Ana Bridge with a 350-foot bridge to open up a constricted section of the river in Oak View.   Widening the channel by 80 feet will improve water and sediment flows, facilitate natural ecosystem processes through restoration of natural sediment transport and deposition, and reduce the need for channel maintenance in the vicinity of the bridge following large storm events.  A new 6’ sidewalk and two 4’ shoulders on each side of the new bridge’s vehicle travel lanes will also facilitate safe passage for bicycles and pedestrians near the Santa Ana Boulevard crossing of the Ojai-Ventura River Trail.

The Ventura County Watershed Protection District has been planning this large scale ecosystem restoration project since 1999, and began restoration activities in 2008 with removal of giant reed (Arundo donax) and construction of a new trailhead at Baldwin Road.  Studies currently underway under another $3.3 million California Department of Fish and Wildlife Proposition 1 grant received by the county in May, 2017 will lead to design and construction of the other downstream improvements before dam removal.
