Potrero Ridge Trail Completed During the COSCA Spring Trailwork Day

Tuesday, March 29th, 2011

View of the new trail (green) from the north-west. Other trails in Newbury Park are yellow, Dos Vientos Trails are blue, and the Los Robles West and Rosewood Trails are magenta.

On Saturday March 26, about 55 Conejo Open Space Conservation Agency (COSCA) volunteers, including a dozen from CORBA and a half dozen from the Santa Monica Mountains Trail Council (SMMTC) trail crew, gathered to complete the eastern end of the Potrero Ridge Trail. This completes the multiuse trail that connects Newbury Park to Dos Vientos by dirt. Now when makling a loop of the trails in Newbury Park, Dos Vientos and Rancho Sierra Vista/Satwiwa, the section between Wendy Drive and Reino Road can be done on dirt. Before, we needed to use 1.35 miles of road/sidewalk.

Construction on this 1000 feet of trail began in the fall of 2009. Originally, there were plans to work on this trail during the 2009 COSCA fall trailwork day, so the brush was cut out along the path of the future trail. However, all the volunteers worked on the nearby Mountain Creek Trail instead, and it was mostly completed, with only one or two rocky or otherwise difficult sections still needing work. (That trail was finished during the 2010 Spring trailwork day.)

The fallback plan was for the COSCA rangers to rough the trail in with a sweco during the winter of 2009/2010, but the weather did not cooperate. The large amount of rain we had that winter kept the rangers busy fixing up other trails that were damaged by rain runoff. The rest of the year was too dry to effectively use the sweco.

During the 2010 COSCA fall trailwork day, the connector trail between the Santa Rosa Trail and the Lower Santa Rosa Trail (AKA Baseline Trail) in the Santa Rosa Valley was constructed.

Finally this trail’s time had come! Volunteers worked for three hours on Saturday morning with near-perfect weather. It was cloudy and cool, and it had rained a couple of days before so the soil was moist, making it easy to dig and pack without making any dust.

Some of the hillside that the trail traversed was quite steep, so the trail had to be dug deep into the hillside to reach the desired width of three to four feet. And parts of the hillside were very rocky, requiring the liberal use of rock bars in some places. But the volunteers worked hard, taking breaks as they liked, to complete the work in less than three hours. On average, each volunteer was responsible for building 25 feet of trail!

See photos of the work in our 2011 COSCA Spring Trailwork Day photo gallery.

After the work was completed, volunteers gathered at the top of the hill for grilled hamburgers, hot dogs and veggie burgers. CORBA gave out 15%-off coupons from REI to all attendees. After lunch, those who signed up through CORBA gathered for a drawing of prizes, ranging in value from $2 to $20. Everyone won a prize, and everyone who wanted one got a patch kit, tire levers, and a bell.

Thanks to all the volunteers and COSCA staff who helped get this new section of trail on the map and on the ground!

Trail Work on Rogers Road Trail Halted

Wednesday, November 10th, 2010

CORBA has learned that the recent trail work that has begun on Rogers Road Trail approximately two miles from Temescal Ridge Fire Road (western terminus in Topanga State Park) has been temporarily halted. This has happened in large part to intense input from the public and CORBA, and a request from CORBA for State Park officials to re-examine the necessity and scope of the work before continuing. We have been told by both the maintenance and ranger departments that officials have met internally and are reviewing the protocol and standards for this work. Additional meetings will be taking place this week to determine how and when additional trail work on Rogers Road Trail may take place. At this time it is unclear when the work will resume and at what level, and/or if it will continue the full length of trail to Will Rogers State Historic Park.

Please stay tuned to this web site for further updates.

CORBA Adopted Trail Damaged by Water Spill

Tuesday, August 31st, 2010

by Danusia Bennett-Taber 

COSCA Los Robles West Potrero trailhead. The spill-induced rut is much worse a little further up the trail.


A power outage at a local water facility caused substantial damage to our COSCA (Conejo Open Space Conservation Agency) adopted trail – Los Robles West / Potrero trailhead section. On Saturday August 21st hundreds of gallons of water poured down this trail  opening huge ruts and even damaging the parking lot. 

COSCA is trying to find the responsible party so they can repair this damage. Until that happens, be aware of this damage and ride safely. 

CORBA has adopted Conejo Open Space Los Robles Trail West (aka Space Mountain to Potrero Rd.)

Saturday, May 22nd, 2010

"Space Mountain" gets its name from the radio towers at the top of the Mountain.

CORBA is proud to announce our adoption of the Los Robles Trail West (aka Space Mountain to Potrero Rd.) under COSCA’s Adopt-a-Trail program. This program allows individuals, civic groups and private companies to adopt trails. Adopting entities agree to provide maintenance for their selected trails on a quarterly basis, as well as regularly monitor conditions on the trail. This is great news for users of this trail. It is a favorite of mountain bikers locally and from all over Southern California. Los Robles West is unique for its tolerance to rain. Good drainage and low clay soil make it ridable after even heavy rainfall, so it is heavily used during the winter. But “good drainage” is not “perfect drainage,” and heading into the summer there are often some rutted sections in need of repair, as well as brush clearance is always required after spring growth. The Thousand Oaks area is fortunate to have a large selection of Conejo Open Space trails open for multiple use. Unfortunately a shortage of resources limits the maintenance performed by the land managers. CORBA is stepping in here to help fill the shortfall.  We hope to engage local trail users to help provide ongoing trail maintenance to this trail. We are looking for volunteers and trail crew leaders to help maintain our newly adopted trail. If you would like to get involved please email us, or call us at 818-206-8213.
