Woolsey and Hill Fire Closures (Updated 12/21)

Tuesday, November 27th, 2018

This past week has been devastating. Our hearts go out to all those who were impacted by the Woolsey Fire and the Hill Fire, which have ravaged our local mountains. We know that a good portion of CORBA’s membership are in areas affected by the fire. A few lost homes and property. CORBA’s storage shed near Malibu Creek State Park survived, though we weren’t able to confirm so until after Thanksgiving. We truly appreciate the firefighters and first responders who put themselves at incredible risk to battle these fires and save as much as they could.

With so much loss, it may sound a little selfish to be concerned about trails. Being able to go for a mountain bike ride can brighten your day and bring a sense of normalcy to these tumultuous times. But with most of the Santa Monica Mountains National Recreation Area closed, where can we ride? We’ve provided a listing below, with links to each park’s web site for the latest updates. We’ll do our best to keep this information current.

Please respect trail and park closures. Our land management agencies have their hands full with fire recovery and damage assessments. Trails in burned areas can be extremely hazardous, even after the fire is “out.”  Fine particulate ash is a lung irritant and can cause severe health problems. Burned, weakened trees can fall at any time, especially in the early days after the fire, or as the ground softens with rain and no vegetation. Once our first big rains hit, trails will be heavily damaged and may become impassable. Just don’t ride closed trails.

As soon as we are able, CORBA will be scheduling trailwork events to help restore trails that will be heavily damaged this coming winter. It might be some time before we can do trailwork or ride. Watch our meetup group or Facebook page for upcoming trailwork events in the new year.

Public Lands Update

Thursday, November 2nd, 2017

This year we have seen legislation introduced to further protect and enhance our local open spaces and public lands.

HR3039, the San Gabriel Mountains Forever Act. Judy Chu introduced this bill in June. The bill would establish two new units of Wilderness within the Angeles National Forest. CORBA worked for two years with wilderness advocates to ensure these newly-proposed designations would not impact trails used by mountain bikers. The bill establishes the Condor Peak Wilderness and Yerba Buena Wilderness units, separated by the Condor Peak Trail. Condor Peak trail and Trail Canyon trail to the waterfall and campground would remain open to bicycles under this new designation.

Rim of the Valley

Rim of the Valley Corridor Preservation Act, S1993/HR4086.

This bill by Adam Schiff/Diane Feinstein would expand the boundary of the Santa Monica Mountains National Recreation Area to include open spaces around the Conejo, Simi, San Fernando, La Crescenta and Verdugo valleys. It does not change any land ownership or management but allows the National Park Service to partner with current land managers to improve habitat, wildlife corridors, and recreational opportunities. It puts into action the findings of the Rim of the Valley Corridor Study. It does not impact bicycle access to trails and could improve recreational opportunities.

H.R. 2323: San Gabriel Mountains Foothills and Rivers Protection Act. This act introduced by Judy Chu would establish the San Gabriel National Recreation Area as a unit of the National Park System. The NRA would cover river corridors and open spaces from the Angeles National Forest border through the San Gabriel Valley. It does not create any new federally-managed public land. It would allow the National Park Service to partner with existing land managers to improve habitat, biodiversity, and recreational access. It would also expand the boundary of the San Gabriel Mountains National Monument to include areas of the Angeles Front Country that are currently outside the Monument.

While these bills have been introduced, it remains to be seen whether they will make it out of their respective committees.

CORBA’s mission includes the protection of the places we play. Nationally, as the current administration proposes major changes to environmental regulations, national monument boundaries (our San Gabriel Mountains National Monument is not expected to be a target of boundary reductions), forest management practices, permitted uses, we stand ready to speak up for our local public lands and the recreational opportunities they provide and we all cherish.

CORBA Supports Wildlife Crossing – Meeting October 12

Saturday, September 16th, 2017

Caltrans is moving forward with the Liberty Canyon Wildlife Crossing across the 101 Freeway, west of Liberty Canyon.  The have released three draft alternatives, for public comment, and will be discussing them at a public meeting on October 12.

Public Meeting

October 12, 2017 – Public Hearing

When: October 12, 2017 6:00pm-8:00pm


King Gillette Ranch Auditorium
26800 Mulholland Hwy
Calabasas, CA 91302

Public Comments

The public comment period will be open from
September 11, 2017 to October 26, 2017.
You’re welcome to submit written comments by
October 26, 2017 to or to the address below:

This is a project that CORBA has fully supported. The wildlife crossing will improve the viability of our wildlife populations, especially our renowned mountain lions,.

Alternative 1 crosses the 101 freeway with a 165′ long bridge. Alternative 2 provides an extension that continues over Agoura Road.  Altternative 2 is further broken down into two ‘Build” alternatives: Option 1, a 48′ wide bridge and Option 2, a 54′ wide bridge.  Though more expensive, we have to support the option that gives wildlife the greatest chance of successfully crossing, Alternative 2, Option 2.

We’re especially excited that all the alternatives include a 5’ wide multi-use trail, linking open spaces and trail networks north and south of the freeway. This would allow one to ride or hike from the Santa Monica Mountains to the Simi Hills.

The Santa Monica Mountains Trail Master Plan is still under development, and we expect to see this crossing included in the TMP, with multi-use trail options linking the two trail networks. There has been no update on the status of that plan.

We urge all mountain bikers to email your support to The Deparment of Transport has all the information at 

Here is CORBA’s letter of support. Feel free to copy all or part and customize for your own comments.

Re: Support for Proposed LIberty Ccanyon Wildlife Crossing

Dear Mr. Kosinski,

On hehalf of the Concered Off=Road Bicyclists Association (CORBA), I am pleased to offer our full support for the proposed Liberty Canyon Wildlife Crossing. CORBA is an all-volunteer membership based 501c3, and a Chapter of the International Mountain Bicyclists Association.

Specifcially, We support Alternative 2, providing the safest passage for wildlife and trail users over both the 101 Freeway and Agoura Road. Further, we support Design Option 2 providing a 54′ wide bridge. We feel this option provides the greatest potential for successful wildlife crossings, and the most room for trail users, wildlife and vegetation.

We are especially pleased to see a 5′ wide multi-use natural-surface trail included. We fully support linking trail networks north and south of the freeway, from the Santa Monica Mountains to the Simi Hills. We also urge that the trails approaching the bridge and the trail over the proposed bridge be designed with ample sightlines and a few wider passing zones to minimize conflicts between trail users or wildlife.

The new trail connectivity this project enables will provide additional recreational opportunities for hikers, equestrians and mountain bikers alike, in addition to its many crucial benefits for wildlife.

Thank you for the opportunity to provide these comments.
