Ken Burton Trail Restoration Continues December 13

Wednesday, November 25th, 2015
MWBA and CORBA Trail Crew

Most of the Sunday, 11/22 crew after they arrived. Thanks guys and gals!

On Sunday, November 22nd, 2015, we had our third full trail restoration work day on Ken Burton trail with the Mount Wilson Bicycling Association. 23 volunteers made the 7 mile, 2000′ climb to pitch in. Bob trailers were used once again to get needed tools and supplies to the work site.

We continued on from where we finished last time. The crews worked feverishly for a solid four hours, clearing an additional 1600′ of trail. We’re making rapid progress, thanks in part to the excellent original construction by the Mount Wilson Bicycling Association in the 1990’s.

After: looking the other direction

The before and after is quite dramatic. Where the trail was previously completely obscured by brush, it is now in better shape than before the fire. Our crews are getting it down to a fine art. We’re using power hedge trimmers for the initial brush clearance, followed by swampers (who remove and stash the cut brush), then loppers and hand saws to fine tune the brush and stump removal.  The lead crew is followed by a tread crew, working to remove stumps and roots from the tread, and pull down slough to restore the original trail tread.  We’re cutting the trail to its original 36 – 48″ tread width where possible, knowing that it will narrow down again with time.

Our target for the day was to reach the Ken Burton Memorial, a plaque dedicated to USFS Battalion Chief Ken Burton, who was killed in a car crash in November 1985. For those who remember the trail, the memorial was just before the very first switchback descending into the Arroyo Seco canyon. We made it to the Memorial at about 1 p.m., leaving time for people to gather tools, load up trailers and ride back down for lunch at 2. Pat Phillips, a local Altadena resident and one of the original construction crew in the 1990’s, graciously hosted us for lunch afterwards.

We’ve also reached the first failed retaining wall structure. In my survey of the trail, only two sections of retaining wall structure failed out of the dozens used, a testament to the work of the original MWBA crew. Those dozens of structures have survived three major El Nino winters and one Station Fire.

So far we’ve cleared approximately .7 miles of the trail, about 1/3 of the work. We have a couple more days of very similar work before it will get especially thick and tough near the bottom. At that time we’ll need to coordinate with the Los Angeles Conservation Corps who are working on the Gabrielino trail, near where it meets the bottom of Ken Burton trail.

Thanks again to all the volunteers who came out to help. Our next work day is December 13 (weather permitting). Our tentative dates starting next year are January 10 and January 24, to be confirmed soon. The more people who contribute, the better our chances of riding this trail next summer!

 

State Parks Fire Road Maintenance Upcoming

Tuesday, November 17th, 2015

We have learned that in a couple of weeks, California Conservation Corps Crews under the direction of California State Parks will start brushing the East Topanga Fire Road in Topanga State Park as the first phase of road maintenance this fiscal year. The second phase of project will be re-grading the road to “out slope” the road for more natural drainage of the road. The notice below will be posted on the East Topanga Fire Road to inform the public of the maintenance project. This project is part of large scale project to “out slope” all  State Park Fire Roads in the Santa Monica Mountains to reduce sedimentation in the Santa Monica Bay. If you have any questions, please contact Dale Skinner at 310/699-1717.

Ken Burton Trail Restoration Has Begun

Tuesday, November 10th, 2015
The Ken Burton trail goes right up the middle of this picture. It's hard to find.

Earlier this year, CORBA used a generous grant from REI to help fund the restoration of the Gabrielino trail to Oakwilde Campground and the Ken Burton trail junction. Pooling resources with the Los Angeles Conservation Corps, CORBA helped fund a private contractor, Bellfree Contractors, to oversee volunteers and Conservation Corps crews, taking the lead on the project. The trailwork needed was so extensive it required the review and approval of Forest Service staff engineers. Much of the trail was completely gone, having been swept away in a massive landslide, or gouged into a ten-foot-deep, twelve-foot wide gully where once you could step over a trickle of water as it crossed the trail. That work was begun last spring, and Los Angeles Conservation Corps continue to work on the Gabrielino in the area. The Trail remains closed to the public beyond Paul Little campground/Brown Mountain Dam while restoration efforts continue.

Meanwhile, we were given permission to begin work on the Ken Burton trail earlier in summer. Work began in October with the trail being inspected, and in many cases searched for using older GPS tracks, by CORBA volunteers.  On Saturday, November 7th six volunteers came out to begin work on the trail. Just getting to the work site requires a 2000′ climb over 7 miles, with several steep, loose sections that are difficult without carrying tools. In one day’s work, we were able to clear brush from about a quarter mile of trail, and restore tread on just over half of that. The tread, once cleared of brush, is generally filled with loose slough that’s easy to clear, but is otherwise intact. A few retaining wall structures near the top have failed and will require digging out the old materials–iron posts, steel mesh, wire and screen–and replacing them.

On Sunday, November 8, we worked with the Mount Wilson Bicycling Association’s and had a crew of about 18 come out to begin work. Several volunteers stepped up to haul bob trailers full of tools, no easy feat with over 2000′ of climbing. With hedge clippers doing the initial clearing, followed by a rake or Mcleod to clear the cut brush, followed by a loppers and pick-mattocks to pull roots, and finished off with a nice outsloping by Mcleod, we had it down to a system. The brush on day two was much thicker than the day before, but we were able to clear about another quarter mile of trail, and with the extra hands, do another quarter mile of basic treadwork.

Brush was thick and the trail difficult to find in places.

After both days of trailwork the crews enjoyed a great meal and some local hospitality. Many thanks to everyone who came out for the work. This trail is special to many people, having been built by mountain bikers, the Mount Wilson Bicycling Association, in the early 90’s. Special kudos to Brad, Burt, Mike, Robin, and Steve who came out both days!

We left almost a half mile of the trail looking like this in one weekend.

We’ll be back out on the trail this Sunday, November 22, again with Mount Wilson Bicycling Association. And if there’s enough interest (and the weather/fire danger cooperates), another crew could head up on Saturday instead (or in addition!). At the moment, we’re approaching capacity on Mount Wilson Bicycling Association’s Facebook Event. For that reason this weekend’s trailwork isn’t being added to CORBA’s meetup calendar. However, a tentative third weekend on Sunday, December 13 is in the works. Stay tuned for details. The Forest Service requires our volunteers to wear long pants, long sleeves, gloves and hard hats which we supply (and with the thick brush, all that gear is a good idea). These can be carried up in backpacks for the ride up and changed into before we start work.

Some of the crew prepare to head back down after a solid days work.

Ken Burton trail is closed to the public. Although we’ve started on it, it’s still dead-end with miles of hike-a-bike through heavy unrideable brush and poison oak once you get beyond our short restored section. People have gotten lost trying to find the trail. We’ll continue working on Ken Burton through the winter and coming Spring, with the goal of having it, and the Gabrielino back to Paul Little and JPL, ready to open by the end of Spring 2016. The more involved you stay, the more likely the Forest Service will open the Brown/Burton/Gab loop, an old favorite of many long-time mountain bikers.

How we get it done. Bob trailers can haul tools for six people.

Photos and Report on Backbone Trail Restoration on Oct 31, 2015

Saturday, October 31st, 2015

On Hallowe’en day, 16 CORBA volunteers along with a half dozen from the Santa Monica Mountains Trails Council hiked up the Backbone Trail from Mulholland Hwy towards Etz Meloy for the third time in a year to cut back the overgrowing brush and improve the drainage.

IMG_1174It seems like all mountain bikers love this 2.5-mile long trail that twists and meanders, climbing gently and constantly up 600′ vertically.

I had hoped that we would have enough people to complete the brushing along its entire length, and the word is we succeeded – almost! There is still one very small gap that hasn’t had the brush cleared, but that section of the trail isn’t badly overgrown.

The CORBA crew focused on cutting back the brush, but the SMMTC crew also worked on the tread – cleaning and fixing the drains and spreading the slough across the trail to level it out. (Slough is the dirt that falls onto the inside edge of the trail from the hillside directly above, resulting in a narrowed trail because people don’t ride or hike on the uneven and loose slough.)

The CORBA volunteers included five students from Calabasas area high schools mountain biking teams, and two of their parents. The teams like their members to give back to the trail community. These kids did a great job helping to restore the trail, as did all the volunteers. Thanks for your help; everybody who uses the trail will appreciate your work when they don’t get scratched up from the brush that used to grow into it!

Building a new trail in Wildwood Park during the COSCA Annual Trailwork Day on Oct 17, and photos

Monday, October 19th, 2015

IMG_0816163 volunteers, including 16 from CORBA, built 3/4 miles of new trail, and an alternate access to the bottom of the Lizard Rock Trail in Wildwood Park in Thousand Oaks, for the COSCA (Conejo Open Space Conservation Agency) Annual Trailwork Day. The new trail bypasses the steepest segment and has a better view because it faces more to the west, away from the Hill Canyon water treatment plant.

Volunteers started arriving at Santa Rosa Valley County Park shortly before 7:30, registered and picked up their package of goodies before getting on one of the shuttles that took them 1.3 miles to the trailhead. There they formed into crews of ten or so, each with it’s own experienced crew leader, grabbed tools and hiked up the trail to the work area. Once there, the crew leaders explained to the other volunteers what the work would be, how to use the tools effectively to accomplish that, and above all, how to work safely so there wouldn’t be any injuries.

IMG_0841Most of the new trail was across a steep slope so our job was to dig out the dirt to form a nearly level trail tread. The brush had previously been cut back and the exact path of the trail marked by bright orange flags so we would know where to dig. The area that my crew was working happened to have relatively few rocks mixed in with the dirt so the work went very quickly, but most of the other crews had a lot of rocks to dig out. The most time-consuming part of the work was pushing the excavated dirt far enough down the hill from the trail so that it would be clear to visitors that it wasn’t part of the firm trail tread.

My crew finished our section in about an hour and a half, so we moved down to the bottom of the trail to help there. The work was the same but went quite a bit more slowly because we had a lot more rocks to deal with and we weren’t as fresh as at the start. But as other crews finished their sections, they came down and pitched in too. Overall, we got the trail finished about a half hour sooner than planned for.

Everybody headed back to Santa Rosa Valley County Park, either by shuttle bus or on foot, for the barbecue that the COSCA rangers famously prepare for the volunteers every year. The lunch was followed by a give-away of trail-related items, the most significant being a new mountain bike donated by Giant Bicycles in Newbury Park. Both the lunch and gifts were to thank the volunteers for their hard work.

All the volunteers did a great job! Besides CORBA, there was a strong representation from the Santa Monica Mountains Trails Council, high-school mountain bike teams from Newbury Park and Calabasas, several Meetup groups, geocachers and others organizations. It takes the support of these organizations and the participation from the volunteers to make the trailwork day the success that it always is. I know COSCA appreciates their effort and we at CORBA heartily thank everybody for their contributions!

Third (and final?) restoration day on the Backbone Trail between Mulholland and Ezt Meloy to be Oct 31

Monday, October 19th, 2015

On two previous occasions in the past year, CORBA and the Santa Monica Mountains Trails Council crews have teamed up to tackle overgrowing brush and drainage issues on the section of the Backbone Trail that climbs from Mulholland Highway to Etz Meloy Fireroad. This 2.5-mile long sections is a favorite for mountain bikers because of the gentle grade, swooping turns and great views of the Malibu coastal area.

With the heavy rains that El Nino is expected to give us this year, we really would like to get this trail finished to prevent water erosion damage. And we could use lots of help from volunteers!

For details and to register so we’ll know how many people to plan for, please visit our Meetup trailwork signup page. Remember, CORBA will take you to lunch afterwards to thank you for your help!

Report on the 34th Annual Santa Monica Mountains Trail Days, April 24-26, and photos

Wednesday, April 29th, 2015

For the most extensive trailwork weekend of the year, 150 volunteers signed up on Saturday, the first day of the 34th annual SMM Trail Days, to help restore trails in Point Mugu State Park (Sycamore Canyon). Another fifty signed up for the following Sunday. The theme for the weekend was to restore trails damaged by the December floods.

On Saturday, the workers split into about 10 crews. Most of them worked on trails in the State Wilderness, east of the main Sycamore Canyon Trail. The CORBA crew of 17 shuttled to the bottom of Guadalasca and hiked to their work area. We were to build rideable paths in three locations where stream crossings had been destroyed. At the first location, the stream had left a culvert half exposed. Some rocks had been piled against it, making a bit of a ramp to help ride across, but it was still quite a hazard. We left some of our crew there to build up more rocks over the exposed culvert to smooth the crossing. When we hiked back down, were we ever surprised to find that they had completely covered the culvert, filling up the bottom of the stream bed to a few inches above the top of the pipe, and the width of the culvert, about 15 feet! You would never have known that the culvert was almost washed away in that flood!

IMG_0735CompBefore we got to the second work site, we encountered a tree that had fallen across the trail. It had burned in the Springs Fire (May 2013) and had just fallen a few days earlier. We spent about 20 minutes pushing it to the side of the trail.

IMG_0816At the second site, the water had eroded the banks, leaving a vertical drop of about four feet down to the stream bed on both sides, with a gap of about 10′ between. Here, another group was to build a ramp down to the level of the stream bed, then another ramp up the other side. This work took special care because environmental regulations do not allow us to move dirt from the bank into the course of the stream, even though it’s completely dry. (This is to keep dirt from clouding the stream and ocean, interfering with the ability of fish to migrate and reproduce.) When building the ramps, the team carefully dug into the dirt, dragged it away from the bank and put it into buckets. The buckets were carried up the trail where the dirt was used to fill in ruts.

IMG_0800The remainder of the CORBA crew continued hiking up the trail almost another mile to the third work site. Here the flood had again destroyed the crossing, leaving a drop of about four feet at the edge of the trail. We were to realign the trail to move it a few feet away from this drop. Again, we had to carefully remove the dirt from the edge of the stream, relocating it into ruts up the trail by way of buckets.

The first and third team finished before the end of the work day, so they went to the aid of the second team. They had the biggest project by far; however, there was only so much that could be done at once due to the confined area of the work.

At about 2:00 pm, everyone hiked back down the trail to catch the shuttles back to the staging/camping/bath/eating area at the Danielson Multiuse camp. We spent the afternoon relaxing and chatting. Meanwhile, the State Park Staff volunteers were stoking the wood-fired grill and making other preparations for the barbecue dinner, consisting of tri-tip, chicken, veggie burgers, baked beans, salad and garlic toast.

Dinner was followed by the raffle, where almost everyone (and perhaps everyone) won an outdoor recreational objet de swag of some sort. The people whose tickets were drawn first won some really, really good prizes!

The work day on Sunday is always a lot smaller than Saturday, so we broke up into just three crews. The CORBA crew of 10 returned to Guadalasca to finish off the middle stream crossing. It was a bit of a race to get it finished by 11:40, as the shuttle was to pick us up at noon at the bottom of the trail, but we did it, just scraping by! We moved a huge amount of dirt, digging out those two ramps, and filled in a lot of ruts on the nearby trail.

Both days, dozens of mountain bikers passed through our work area. Most of them thanked us for our work as they went by, recognizing that they wouldn’t have to carry their bikes across the streams when we were finished. A few stopped to ask how they could find out about future trailwork events so they could help out too.

View the photos of Sunday trailwork on Guadalasca in CORBA’s photo gallery.

Back at the staging area, we had a lunch of leftovers, followed by another raffle drawing for Sunday’s volunteers. We departed the park about 1:30 – time for a shower!

Thanks to the CORBA volunteers and the many others who put on and attended this event, helping to keep these popular State Park trails in great condition!

Another successful COSCA Trail Work Day held March 21st

Monday, March 23rd, 2015

Over 100 volunteers, including 16 from CORBA, gathered in the Hill Canyon region of Wildwood Park in Thousand Oaks to help with the 2015 COSCA Spring Trail Work Day. The volunteers broke into six crews and worked on three different trails.

Crews 1 and 2 worked on the Gas Line Road, a dirt road that leads from Hill Canyon to the Canyon Overlook Trail that was build during the 2012 Spring COSCA Trail Work Day. Most people cleared loose rocks from the road and filled in some ruts, while a few built a short access singletrack from the parking area at the bottom.

Three crews worked the bottom of Lizard Rock Trail, leveling the tread where ruts had started to form, clearing overgrowing brush, building a reroute of a few hundred feet, and building a long ditch to keep water off a chicane. The latter is where the CORBA crew worked, and spent most of their effort.

Among the CORBA volunteers were five members of the Calabasas high school mountain biking club and two parents. There was another contingent from Newbury Park High School working with one of the other crews.

The final crew worked on the Eagle Point Trail, clearing dirt from the many steps and doing brush removal.

The Santa Monica Trails Council trail crew did much of the preparatory work, and fielded crew leaders for all crews except for CORBA’s.

All the volunteers gathered back at the parking area about noon for the barbecue provided by the COSCA rangers. The turn out was unexpectedly large, about double previous years; even so there were plenty of burgers (beef and veggie), hot dogs, chips and sodas for everybody.

Thanks to the CORBA volunteers and others for helping to keep the local trails in great condition!

Report on Feb 28 Bark Park Trail Restoration, and Photos

Tuesday, March 3rd, 2015

The New Millennium Loop trail system in Calabasas is very popular among mountain bikers and others, but it has very little if any maintenance since the trails were built a number of years ago as part of The Oaks gated community. In general, they have held up pretty well, but nature is taking its relentless toll.

Recently, high-schoolers with the SoCal High School Cycling League, with help from CORBA and the Santa Monica Mountains Trails Council, have been helping to restore these trails. On January 31, they helped complete a new trail along the Historic Loop segment that bypasses the swamp. This past Saturday, February 28th, ten kids from Calabasas and Newbury Park mountain bike clubs and 5 young sailors from Naval Base Ventura County, with guidance from CORBA and Trails Council trail crew leaders, repaired about 0.8 miles of the Bark Park Trail.

With the heavy rains in December, ruts started to develop along the trail and a sinkhole about 6′ long and 3-4′ deep appeared. We were going to fix that and address the drainage issues on the trail above it that caused it to appear. Sometime in the couple of weeks before our trailwork day, someone filled in the sinkhole, saving us some time, but we still needed to widen and level the trail around where it had been. Also, the tread had to be repaired so the water would run off it, rather than down it and enlarging the ruts.

Over the next few hours, about 15-20 drainage nicks were built and parts of the trail were restored to their original flat but slightly out-sloped state, to enable rainwater to run straight off the outside edge. Three switchback drains were also cleared of vegetation and silt to restore them to their original condition.

When we were finished, we moved to nearby Sharky’s for a hearty lunch of Mexican food.

You can see more photos of the event in our Bark Park trailwork photo gallery. Thanks to the high-schoolers and sailors who came out to help – everyone did a great job!
