Surfers Point - cobble berm monitoring

One of the innovative components of the Surfers Point Managed Shoreline Retreat Project is the application of a buried cobble berm to provide shoreline protection for the bike path and parking lot that were moved inland.  The berm is 8 feet thick and approximately 80 feet wide and is buried beneath constructed and revegetated sand dunes.

As a reminder of why this project was constructed, here is a photo of the bike path in 1994:

Historically, the area of greatest erosion is immediately downcoast of the Ventura River levee, which acts as a groin in blocking littoral (along shore) sand transport.  This area continues to see dramatic seasonal changes as the beach comes and goes with changing wave climate.  The typical summer beach looks like this:

 While currently the winter beach looks like this:

So depending on when you visit the site, the "toe" of the cobble berm may or may not be evident.

The following is a collection of photos taken from the Ventura River Levee at the west end of the project site looking back towards the beach restoration area.  This series of photos shows the excavation of the parking lot and the importation of cobble and sand to create the buried cobble berm.    It also illustrates the seasonal changes and the evolution of the cobble berm in response to the changing wave climate and sand supply.  Note that the spur groin in the right foreground can be almost buried with sand in the summer months.

We will continue to photo document this aspect of the project to demonstrate the effectiveness of the cobble berm to adapt to future changes.

Matilija Coalition Update February 2014

Matilija Dam Ecosystem Restoration Campaign Update 2013-2014

Matilija Coalition:   One of the most common questions we are asked, whether at public events or just hanging out at the beach, is "when is that dam coming out?"   Although recent progress on actual dam removal has been painfully slow, there remains considerable interest and support within our community.

The Matilija Coalition continues to provide public outreach and education on Matilija Dam. We conducted 4 field tours in 2013, most notably the SERCAL conference (Society for Ecological Restoration California Chapter SERCAL conference 2013).   This month I was invited to give a short update to the Ojai Rotary Club.  We also work with classes from UCSB, Ojai Valley School, and Ventura College.  In 2014 we will also host a fieldtrip for Ventura High School AP science class and another AP Science group called "Get Inspired".

Dam Removal Update:
Unfortunately, little progress has been made since the 2004 federal feasibility plan was approved by Congress in 2007.  The original schedule had dam removal slated for 2012, but that date slipped by quickly with a lack of federal funding and fundamental problems with the plan.  As detailed design
progressed it was evident that actual costs for the $145M project were quickly surpassing $200M! We have been working with federal, state, and local agencies to resolve these issues since 2008.  Milestones in this effort are documented at 

In 2012, the Matilija Dam "Technical Advisory Committee (TAC)" completed a work plan for the next steps in resolving the issues with removing Matilija Dam.  The studies will include:

Task 1: Dam Removal Plans and Costs - to complete a screening and evaluation process of feasible dam removal and interim notch concepts, and ultimately to complete a conceptual design of up to two (2) preferred concepts that could move forward into permitting and implementation.

Task 2: Sediment Analysis of interim and dam removal schemes - evaluate the in-channel and reservoir-area responses to the proposed full dam removal initial options and concepts that will be screened and evaluated in Task 1, with a primary reliance on the simulation of sediment transport processes to evaluate downstream sedimentation and associated flooding risk, as well as (included in Task 1) geomorphologic changes, short- and long-term habitat impacts, and water quality.

Task 3: Robles Diversion Mitigation - develop methods to mitigate the impact to water supply through supplying water of acceptable quality during the period of turbidity impact. The work of Task 3 would be done in close collaboration with Tasks 1 and 2.

The completed TAC reports may be downloaded at

In 2013 a consultant team was selected to perform the additional studies recommended by the TAC.  A contract was recently approved by the Ventura County Board of Supervisors, with the work to be sponsored by the California Coastal Conservancy.  Work should begin in March 2014.  A meeting will be scheduled around the May time frame with the project "Design Oversight Group" in order to consolidate information and brainstorm dam removal alternatives.  The studies are anticipated to take about 18 months, at which point we should have a short list of potential project alternatives which will require still more engineering for implementation.

The Matilija Coalition will continue to advocate for the most cost-effective plan possible.  Recognizing that we are in an era of greatly reduced federal funding necessitates simplifying the project in order to reduce costs significantly.  For an example of the negative impacts of federal spending cuts, visit the beaches of Port Hueneme.

DamNation - the film

The world premier of the new dam removal film will be at the South by Southwest Music and Film Festival, March 7 - 16, 2014 • Austin, TX.  We eagerly anticipate local screenings to reinvigorate the conversation on Matilija Dam.

"This powerful film odyssey across America explores the sea change in our national attitude from pride in big dams as engineering wonders to the growing awareness that our own future is bound to the life and health of our rivers. Dam removal has moved beyond the fictional Monkey Wrench Gang to go mainstream. Where obsolete dams come down, rivers bound back to life, giving salmon and other wild fish the right of return to primeval spawning grounds, after decades without access. DamNation’s majestic cinematography and unexpected discoveries move through rivers and landscapes altered by dams, but also through a metamorphosis in values, from conquest of the natural world to knowing ourselves as part of nature."

Surfers Point Winter 2014

A boardwalk is the most recent addition to the Surfers' Point Managed Shoreline Retreat project.  Designed to provide access around the 'cobble garden,' the boardwalk is constructed with weatherproof plastic decking and adds a finished touch to the bike path.  We have received positive comments from the 'regulars' at the beach, and people seem to be enjoying the little detour off the paved path.

The project also appears to be functioning well during winter "king tides" and storm surf.  This aerial overview shows the wet sand from high tide early in the day as well as the exposed cobble berm on the west (left) side of the project.

 The managed retreat project was designed to mimic and enhance the natural function of the beach which changes throughout the year.  The erosion of the beach in winter months is expected with high tides and surf, and wave action naturally sorts the sand and cobble.

This cobble, which was buried beneath sand just a month ago, extends beneath the dunes all the way back to the bike path.  The 'cobble berm,' which is is up to eight feet thick, provides a significant mass of natural river rock to protect the bike path from extreme events and future sea level rise.

The aerial photos below were taken at extreme low (minus) tide, and clearly show the cobble in the intertidal zone - it is this cobble that provides the foundation for the marine delta that creates the "point" at the mouth of the Ventura River.

Beach erosion and federal funding

Our coastal neighbor, Port Hueneme, has been in the news a lot this year due to beach erosion which is threatening streets and infrastructure built along the shoreline.  Over the summer the city began reinforcing the seawall that protects the road, but didn't have money to complete the project.  The California Coastal Conservancy recently approved $2M for additional construction. The aerial photo below shows the extension of the rocks along the beach toward the pier.

The aerial photos below from show the loss of sand from 2010 to 2013:

This dramatic erosion is the direct result of federal budget cuts which eliminated funding for the required biannual harbor dredging.   Harbor jetties block the constant movement of sand down the coast, so  regular dredging is required to keep the harbor mouth open and bypass sand.  Hueneme beach is entirely dependent on sand that is dredged from Channel Islands harbor.

This aerial overview shows the sand that has collected in the trap created by the offshore breakwater at Channel Islands harbor. If this maintenance is not completed beaches "downstream" are starved of sand and rapidly disappear.

Ventura Harbor has been suffering the same problem.  This photo was taken while the dredge was operating in February 2013.

These photos show how much sand has built up in the Ventura Harbor sand trap.

aerial overview of Ventura Harbor shows sand buildup between north jetty and breakwater 

After nearly a year of meetings and conversations with the Army Corps of Engineers the Ventura Harbor received $2.5 million of the $5.9 million it needs to dredge. That money only paid for about 235,000 cubic yards in 2013, or less than half the 600,000 cubic yards sand required annually to keep sand moving down the coast.

The budget crisis prompted the Ventura Port District to consider an offer to sell sand to Broad Beach in Malibu, a beach that eroded in response to removal of natural sand dunes.  But BEACON director Brian Brennan said "The erosion agency isn’t about to just hand over the Ventura Harbor sand, because it is vital to protecting properties on coastlines in Oxnard and Port Hueneme. Those beaches need to be replenished with sand annually." (see Ventura Harbor's excess sand may be treasure for Malibu residents)

According to a recent Port Commission newsletter, Ventura Harbor anticipates about $3.7 million in federal funding, enough to dredge up to 400,000 cubic yards in February or March.  Because this is still partial funding it will result in accumulation of another 200,000 yards to the ongoing buildup in the sand trap and downcoast deficit.

This article in the VCStar sums it up:

The problem is Congress has not allocated enough money to replenish the badly eroded beach with more sand, something the U.S. government is obligated to do.
That obligation was made decades ago when the Port of Hueneme was built. The port project interrupted the normal flow of sand down the coast that had replenished not only Hueneme Beach but many other local beaches as sand washed away.
Hueneme Beach is supposed to be replenished with sand every two years through dredging by the U.S. Army Corps of Engineers. The sand is taken from a sand trap located at the mouth of Channel Islands Harbor.
In the most recent dredging, the corps was unable to pump the 2.5 million cubic yards of sand required by the beaches because of what federal officials called budget restraints.
Port Hueneme Mayor Ellis Green said...Port Hueneme’s lack of sand “is a man-made problem,” 
“The solution to this problem is simple,” he said. “The federal government needs to fulfill its obligation and pump the sand that is now in the sand trap to our beaches.”

backcountry hazard - ticks and lyme disease

Mountain biking Middle Lion Trail, Sespe Creek watershed
 - Mountain Bike Action Magazine Nov 2013

Our area has some amazing backcountry.  So when the surf is flat, there's still lots of things to do.  I have hiked and biked the local trails for decades, and generally spent a lot of time outdoors.  Apart from the usual cuts and bruises (and a mild concussion), I've always stayed fairly safe. No rattlesnake, scorpion, or shark bites.  But last April, a ride on the trail pictured above changed my life.

Hard to imagine something so tiny has the potential
 to wreak so much havoc
Over the years I must have been bitten by hundreds of ticks.  But this time I got a bad one.  I'd always heard of Lyme Disease, and was aware of the potential hazard from ticks.  If caught soon, ticks can be removed fairly easily.  But left on the body for too long, a tick will embed itself under the skin to feed on your blood.  Along with anticoagulants and anesthetics, it can inject a potentially life threatening bacteria into your body - a spiral-shaped bacteria (spirochete) called Borrelia burfgdorferi.

Common on the East Coast of the United States, Lyme Disease is becoming more prevalent in our area.       Some attribute this spread to our intrusion on natural processes and climate change.  It seems everyone I talk to knows someone affected by it.  Unfortunately mistreatment and misdiagnosis is the norm, which can lead to long term disability and even death.

I will be ok, but it will take many months to recover.  Although my initial diagnosis and treatment was inadequate, I am now under the care of  a LLMD (Lyme Literate MD.)   But this was only because I knew exactly what happened and received good referrals.  Those less fortunate endure years of misdiagnosis and an endless misery that I would wish on nobody.

According to the International Lyme and Associated Diseases Society (ILADS):

  • Up to fifty percent of ticks in Lyme-endemic areas are infected with Lyme or other tick-borne diseases. With odds like that, if you have proof or a high suspicion that you've been bitten by a tick, taking a "wait and see" approach to deciding whether to treat the disease has risks. The onset of Lyme disease symptoms can be easily overlooked or mistaken for other illnesses. Once symptoms are more evident the disease may have already entered the central nervous system, and could be hard to cure. This is one case in which an ounce of prevention really is worth a pound of cure.

I post this information so people will be aware that Lyme Disease is a serious problem in Southern California, and that although your general practitioner may not be 'lyme literate,' there are doctors who can help.


The film "Under Our Skin" exposes the horrors of Lyme and the controversy and conflicts surrounding the disease.  The full feature is here:

Coastal Resilience - Ventura County

The Nature Conservancy is the lead in a study to assess potential changes to our coastline with future sea level rise and other climate change effects.

According to the website, The Nature Conservancy is leading Coastal Resilience Ventura - a partnership to provide science and decision-support tools to aid conservation and planning projects and policymaking to address conditions brought about by climate change.  The primary goals of Coastal Resilience Ventura are assessing the vulnerabilities of human and natural resources, and identifying solutions that help nature help people.

The recent report outlines a Catalogue of Local Sea Level Rise Planning Tools.  Key recommendations are:

  • Sea Level Rise should be included in General Plan
  • Sea Level Rise in should be included Local Coastal Program (LCP) Update
  • Sea Level Rise in should be included Zoning Code Updates
  • Sand Dune and Wetlands as Barriers and Buffers
  • Flexible Options: Managed retreats, Transfer of Development Rights (TDR), and project siting and design considering sea level rise

Another product of this project is a web mapping tool to help illustrate potential inundation areas from sea  level, tides, waves, and river flooding.

Surfers' Point Managed Shoreline Retreat project - 9-23-2013           aerial composite by Rick Wilborne

These aerial photos provide a wide angle view of the entire project site.  Despite a dry year, the progression from February to September shows that native plants are doing well in the constructed dunes.  Repeated weeding has kept invasive weeds under control.  The seasonal difference in the high tide line is also evident.  The toe of the cobble berm is visible on the west end (left of photos) in February, but buried during the summer.

A boardwalk will be constructed in December, an additional part of the master plan that is being funded by the California Coastal Conservancy.  We will seed the area around the boardwalk with purchased and collected seeds after construction is complete.

Photos below are from the volunteer workday on Saturday morning, November 2.  We continue to weed non-native plants (mainly sea rocket, ice plant, bermuda grass) from the dune restoration area.  Volunteers also collected seed from some of the established plants and broadcast throughout the dune areas.
