    Awesome to see that there are organizations in CA progressive enough to support and facilitate the construction of such trail features.

    Did a few Clementine,Culvert,Confluence loops today...and what a change!
    These guys have the equipment to get it done...
    They are doing an awesome job....love the use of the long PVC pipe to keep the flow line.
    And looked like FATRAC was involved too...

    I don't remember hearing anything about it either until we were out there riding. Fatrac and forest trail allience were out there with ASRA.

    The Culvert Project is a collaborative effort that is currently supported through:

    - FATRAC
    - Forest Trails Alliance
    - REI
    - Auburn and some Sacramento area bike shops

    A special call out for Auburn Bike Works in Auburn as their staff have been involved from this project's inception and they have recruited many of their riders to work on this project.

    This project will take place over the course of the next 12-18 months. If you would like to stay on top of what is happening, I'd recommend you join the following Google Group:

    ASRA Culvert Trail Improvement Project | Google Groups

    I post updates there on a regular basis.

    I am still a mile high after this weekend. In the 20 years I have been pursuing trail building the combination of a killer alignment to work with and the great people that came out made this my favorite trail building experience EVER!!!

    Our vision in creating a community based trail building organization came to maturity with this project. It has been our goal to connect to and empower organizations like ASRA and FATRAC with the equipment and skills to aid in producing tangible results. FTA is a Petr-dish of sorts for the mad bacterium of the twisted single track mind. It is our goal to continue to grow this organization with both the blood of the possessed and the steel of the machines that will shape our tomorrows inspirations.

    If you believe in what is possible, consider shaving a sliver of the value of your suspended mount and invest it in FTA. No Paid Staff. All $ goes to dirt. 8 projects underway this year bringing 13 miles of new single track your way (if we can raise the money for the NEPA environmental costs). If $ is short, shed sweat instead and come and join one of our 10 day trail builds this spring!

    Zachi, are you doing the NEPA, using a consultant, or are you paying for FS staff? Assuming it's on USFS land of course...

    I have to research that flow pipe thing...first I've heard of it.

    Steve,

    Thanks so much for putting this together! This was the most productive trail work day I’ve been on and I can see how the new changes will get some “wee!” responses. I can’t wait to ride it myself.

    I was also very impressed with the Forest Trails Alliance professionalism; from design, sustainable issues to conflict resolution - if someone needs a team working on trails - these are the guys.

    And special thanks to State Parks for being open to making this trail more than just a straight line through some rocks.

    Pics for those who could not make it.

    Delicious burm.... & FLOW sticks guide the replacement trail through the old straight

    The trail workers let a few of us ride the new section on Sunday and it was awesome. Love the two new tabletops. Great work by everyone involved!

    The FLOWSTICKtm is a fantastic tool we utilize, one of many secrets...

    I can howl like a coyote, that is the closest skill to doing environmental work I possess. Each land manager and project is unique, the USFS uses their own in-house team which is much cheaper.

    But this is just the tip of the iceberg with the spice available when you create an organization filled with obsessive trail lovers like me that is all about creativity, empowerment and flowy trail. It is our goal to have FTA be the sharpened tip of the spear that regional mountain biker groups (acting as the shaft and power) can utilize for projects. Please consider helping us shape this idea and vision into an effective tool for our area. It is through education of the bigger picture that we can create team approaches to projects like this and open doors of opportunity with land-managers.

    Things that you can do to help;
    • Help us raise money.... no money goes to payroll or staff, all volunteer… but we do need $$ for environmental fees, insurance and to invest in equipment (most of the equipment was on loan)
    • Be a part of our crew… support the vision by wearing the colors and gear, our goal is to create a workforce image for public relations and convincing land managers to give us opportunities
    • Help us market our vision…. Flyers, events, and especially need creative talent for our new website…
    • Ride more…. And listen for opportunities to support the vision for sweeter trails

    there should be a 'Wd40 to rear rotor application station' at the top of the trail - mandatory for any dh or 'all mountain' bikes.

    Do these trails have to follow the 5% rule imposed by the forest service like they did over in Forest City?

    Auburn State Recreation Area is administered by State Parks, not the USFS. I believe that State Parks manages the land pursuant to a contract with the U.S. Bureau of Reclamation. The land was originally acquired by the federal government for the potential construction of the Auburn Dam.

    A big shout out to everyone who came out and helped this weekend!!! This was such an awesome accomplishment in only 2 days!! I want to personally thank Steve, John and Zachi for their dedication and expertise on this project. It is really great that we were able to get the group of people together that we did and sustain the project momentum. I can't wait for the next phase, to here more great input from everyone.

    Trail Standards adopted by different agencies identify an average grade to build to. The USFS in our area uses 5% for this magic number. Although we initially thought we would be limited, it almost doubles the down hill runs on our trails without loss of the needed gravity to inspire speed.

    It has trained us to be way more smart about avoiding designs that kill speed for no reason. The culvert trail has no limits and has grades that are up to 30%. Our goal is to compensate heavy grade by designing features that spend this capital like berms and jumps. The biggest issue with grade and fast speeds is the need to increase erosion measures while not interrupting flow. Non intuitive design causes braking bumps.

    This is the most challenging trail I have ever worked on. God help us get it right!

    This trail (Culvert) connects to the Confluence trail which are both fun. There are a few options, but you can't go wrong with climbing Clementine- to Connector (across the the street) to Forest Hill Divide Loop ( counter clock wise ) back to Connector to Fuel Break (which gets you to the Culvert Trail. It's a good mix of flowy, scenic single track and finish with a more technical down hill.

    Zachi and the rest of the crew have also done a great job in Forest City (between Nevada City and Downieville) and surrounding communities. If you haven't checked out the flowy bike friendly singletrack there you are really missing out! Well worth riding, volunteering, joining and donating!!!

    thanks for your hard work!

    I got to ride it today and it was very slow, probably due to the ruts/mud, but looks like a lot of work went into it!

    Is there any way you can fix that section of failed berms on FDLT that fatrac put in a few years ago? I'd donate some money if you could fix that horrible section.

    Good job! Some footage so far

    Was up in Auburn Sat and Sunday riding and was very impressed with the massive amount of work the voulentters have done. They have definitely held true to keeping the trail fun and fast. I have some chest mount GoPro footage of some of the riding we did, with a glimpse of the fantastic work. Keep it up guys!

    If it is the same section I am thinking of it is way over grade (30%) with the berms on either side??. I love the area and trails and think this could be the beginning of some cool efforts to dial in the trails including this spot. Convincing the state parks that we have an competent effective working group that can build and design effective trail is our first goal to open more possibilities. While I love to build in the sierras with the SBTS bros, winter makes this area the sweet retreat!

    Our goal is to fatten the Culvert with some sweet flow that resolves serious erosion and other issues. We want to build not only killer trail but a strong group of skilled advocates. Make sure you join the project group ' asra-culvert-trail-improvement-project@googlegroups.com ' and come out and join the effort.

    Build it, Ride it
