TRAKS Cangkul Day In Bukit Kiara - Sunday, 16 June 2013

image

  • Date: 16 June 2013
  • Time: 08:00 am
  • Venue: Bukit Kiara
  • Meet At: 4-Ways

As most of you have been noticing, our trails are getting a little more challenging with each passing day. Simple climbs are becoming quite rutted, and one the easiest of all of our trails has now caused someone to have a lovely stack which resulted in a few broken bones.

The simple solution to preventing heavy erosion is by making sure there are water bars along the trail, At the top of each climb, similarly make sure that there is a channel to prevent water from gushing down the steeper sections. If you keep your eyes open, you’ll notice that there are actually such things on ALL of our trails, but these have become filled with sand, leaves and other debris which make them hard to see. Clearing them will be the primary purpose of this day.

We will meet at 4-Way at 8 am where you’ll receive instructions on what to do. We’re hoping that all of those who have adopted a trail under the “Kiara Adopt A Trail” effort will also show up and be the lead for their particular sections. If they aren’t available, then a nominee will be found to lead. 

If you have your own cangkul, please bring one along. If you don’t know what one looks like, please see above!!! Mr. Cock is the most prevalent brand in Malaysia and can be bought for less than RM 30 at hardware stores. Ace Hardware may be a wee bit more. We will bring a stack of them, but no where near enough to tackle the number of people we hope will show up.  Our trails need you.

Between now and 16 June, a few of us will start tackling the trails further afield from 4-Way. If you’re interested in helping out on any of the weekends between now and 16 June, post a message in reply to this thread and we’ll let you know when/ where.

We will also begin planning for some of the more serious work that is required. On our list is the repair of the bridge on Snakes & Ladders, the descent and climb on Cheeky Creek, the climb out of Wasteland towards Bar-a-kuda and more. Hopefully the rains will start abating to help us out!

The “Wasteland” Trail @ Bukit Kiara: A Short History By Stanley Ng

Sure, we have some really cool sounding names for the trails around Bukit Kiara. Too cool in fact, you might ask? All the trails earned their respective names for a good reason, take for example “Pure Quill” was named when the trail builder(s) in the form of Tony Stapleton (and company) spotted a porcupine nearby while building the trail. Yes a porcupine, who would’ve expected to see such creatures in our own backyard? The “2K” trail was named that because, well, it was originally 2kms in distance when it was first built!! Now as for trails such as “Boner” and “Clenched Sphincter”, let’s just leave it at that…

Do you know why “Wasteland” was named as such? Take a short walk with me down (an equally short) memory lane, and have a look at these:

Get the idea yet? A lot of the dead twigs sticking out of the ground in the photos above used to be the top branches of trees, just to give you an idea of how deep the valley used to be!

In 2009, when the developers started leveling the hill to build the new bungalows that now overlook Sri Hartamas, they needed to build an access road to go up the hill in order to cut it. What do they do with the excess soil? It all got conveniently dumped over the side. And I mean ALL of it. Right beneath it lays “Boulder”, which was the link between “Plan C” to “Upper Short”, and even though it was easily a 10-15 foot drop, it was completely blotted out of memory. And it didn’t stop there. The valley that lay below Boulder got completely filled up as well. This resulted in the end (or start, depending on which side you rode in from) of “Bar-A-Kuda” getting cut off as well, effectively severing 2 main trails that provided access from the Sri Hartamas side into TTDI.

And so the Penghulu jumped into action, looking for a way to reconnect the trails. First was a gallant but alas futile attempt to connect the end of “Bar-A-Kuda” directly to the broken tarmac section just below the new bungalows, but that ended up being named “Slide Zone” for a good reason. The soil took very long to settle, and was perpetually shifting, hence the Penghulu was forced to focus his efforts further down the valley, or “Wasteland” as we know it today.

The only obstacle in between the valley was a small stream crossing, which meant a bridge was needed to span across the 2 banks. This resulted in the birth of ‘Bridge V1.0’ (which was really a skinny!!).

In the following months to come, the skinny started to rot, as any normal untreated wood would in our extremely ‘mild’ weather conditions. This brought about the need for a replacement bridge. By now, the TnT fund was starting to kick off, and there was enough money to allow our Penghulu to utilize it to construct a proper bridge with good, local hard wood. Thus, ‘Bridge V2.0’ was born.

image

Of course, in between the years till today, the supporting columns which had been hand built with rocks and clay (all natural resources that Mother Nature has provided), had started to fall apart from heavy rains and strong river currents, and we’ve had to rebuilt/reinforce them at least a couple of times now.

Amazingly though, it is still the same wooden bridge you see on “Wasteland” today, and it was only the supporting columns and the banks that have needed some TLC, as was evident in the recent bout of wet weather.

image

The recent ‘mini trail day’ in early Feb 2013 was an impromptu call to get a small group to focus on rebuilding the support columns, with excellent results.

‘Refurbished’ in Feb, 2013

So there you have it, the beauty and history of “Wasteland” in a nutshell. What was very evident in the photos is the amount of erosion that has taken place over the years. I did not think much of it until Phil Bee pointed it out when he re-shared these old photos with some of us again.

The work crew from 2013, note the amount of erosion that has gone on underneath the bridge!

The main culprit is the stream that wends its way under the bridge, and we all know how much rain we get in KL, not to mention the recent bout of extremely bad weather as well. In the photos, the area under the left span of the bridge does seem to fare much better without the stream going through.

If this amount of erosion was caused solely by natural causes, can you imagine the impact of bikes on wet and muddy trails? Not forgetting riders who drag their rear brakes just because they don’t know how to control their ride?

Learn the right riding techniques, come out and do some trail work, and then you will really get to enjoy your ride!

Bridge on Wasteland, Bukit Kiara - back in action! All the King’s Engineers and All the King’s Banglas, put the bridge back together again.

Many thanks to Philip Bee, Michael Tighe, Alan Knowles, Laurent Ane, Farizul Zulkifli, Conrad Fawcett, Cheryl , Steve (Cannondale) and the other Aussie bloke on the Polygon, plus the others who passed through and helped in one way or another.

Snakes & Ladders

Bukit Kiara Damage Report, 28th Jan. 2013 - By Phil Bee

So after a few weeks of lovely dry weather, we were hit by some pretty massive storms on Thurs & Friday last week.

Some of you probably have seen a pic on FB of the snakes bridge - well here’s some more. Thanks to the good blokes who first cleared the branches on Saturday to at least make the bridge passable. They posted on FB, I don’t know their names…

First up the bridge on Wasteland is getting dodgier by the day - although each half is squint it is still solid enough, however this time around the middle support pile has collapsed a bit, and the Plan C side support pile has slipped some more. Will need work pretty imminently.

As you ride along Snakes & Ladders toward the bridge there are a number of little landslides which have dumped waterlogged soil on the trail, no biggie but a bit messy. The bridge however - well the big landslide up the hill has given way some more. A rubber tree which was formerly in the hillside has come down into the gulley, and smashed into the bridge itself. Amazingly though the bridge is relatively intact - the long beams themselves twisted over sideways partially and have bent - however one is completely intact, and the other only split a little.

We worked today to get the weight of the tree off the bridge so it should last OK. It is solid when you walk on it, but unridable due to the curve it now has…! Also half the top timbers came off, we hammered some of them back on, to make it walkable before we left (not shown in the pics).

The side of the landslide above is also mobile. The remaining trunk & branches of the tree is going to come further down the valley over time so we’ll likely have to chop it again, and again as it comes toward the bridge. The far bank has also caved in a further 1ft.

Elsewhere there’s another tree down further along Snakes & Ladders (can ride under currently). Coming up the road from horse club/Apollo, there’s a big landslide, which similarly brought down a rubber tree from above - this time smashing into the metal fence, which didn’t survive nearly as well as our snakes bridge. Riding from there up to Bar-A-Kuda there are several more of these landslides - maybe 10 of them. JLN have some slope stabilisation work to do there.

On the plus side - we opened up Sticky Corner to traffic today. Despite the rain it is fairly solid now - a little soft in the middle few meters but elsewhere OK. Could do with some traffic to bed it down.

We’re going to need some rocks to armour the water drain down the left side - it’s eroding already, but is at least off the trail now.

TRAKS Trail Day, 13 Jan. 2013: Rebuilding Twin Peaks @ Bukit Kiara

By Stanley Ng

Done and Dusted! Thank you all who came out this morning, despite the dark clouds which was followed by the rain. I sure hope you all had fun plodding around in the mud!! You guys were all amazing!!

We covered Twin Peaks from bottom to the top and then down TnT as well! Without all of you and your commitment, this would not have been possible.

People just started showing up one after another, I couldn’t keep track anymore nor remember new names after a while. If I miss out your name or your friend, please add or tag yourselves and your friends to this post just so we know and can appreciate your efforts.

In no particular order:

  • Scott Roberts, Liz Chin Roberts, Michael Tighe, Philip Bee, Steve Thoma, Laurent Ane, Joel Maclou, Eric James Bubeck, Lee Wai Yuan, Michael Phoon, Chris Khoo, Julian, Riza,
  • (The PCC crew) Pete, Gerard, Simon, Dorothy, Debbie, Choy, Yong Hong Chye, etc)
  • (D&P crew) Nick, Tee Senior, Yoroshikune, Jimmy, Tattoo, Michael, Chang, Alex, etc.
  • Johari, Norway, Ian, Mark Shine, Mark Bedford, Winston, Eric Chu, William Lai, Dick, Shang, Steve Yap, Kennex Khong, Megat Faiz, Andreas Thompson, Rob Schorr, Paul Lee + 2 friends, Jasmine (??) and partner, HP, Visan + 2 friends.

Thank you very much everyone! Water bars were built and/or rebuilt, ruts were filled, Sticky Corner was repaved. A special mention to Steve Thomas and Caesar Ang for providing all the (extra heavy) bags of aggregate to be incorporated into the trails to hopefully allow it to last longer!

Now here’s the most difficult part. PLEASE STAY OFF TWIN PEAKS until it has had time to dry off and bed in properly!! I bet you even as I’m typing this, there’s tyre tracks on the soft water bars already!! If we get a few days of dry weather, it should have a chance to dry up properly and then it’ll all be fun again!

Pat Brunsdon’s Top 10 Rules For Trails In Malaysia

Pat Brunsdon in Sungai, Bukit Kiara, Malaysia

1. The “Half Rule”

The trail grade (percent slope) should be no more than half the grade of the sideslope/hillside that it contours along. For example, if the hillslope the trail runs along is 16%, then the grade of the trail should be no more than 8%. If the slope exceeds this half rule, water will funnel down the trail and cause erosion.

2. Maximum Average Slope Of 10%

Trails should not have a sustained average grade of more than 10%; that is, rise or fall of no more than one metre in 10 metres. Even if a trail passes rule No 1 (the half rule), it can still fail Rule No 2. It’ll suffer from erosion because it’s too steep.

3. Maximum Peak Slope Of 15% To 20%

It’s possible to have a very steep section for short stretches. Local soil types will dictate how steep this can be. Special protection may have to be added to prevent erosion such as extra water bars, steps or rock armouring.

4. Grade Reversal

Trails should not have sections that are continuously up or down for more than 50m. Instead it should wiggle its way up or downhill with short sections where the grade is reversed (see illustration). This forms a natural water diversion so that it doesn’t build up too much velocity or volume.

5. Outslope

Trails should be built so that the surface slopes downhill by about 5%. This allows water to flow off the trail at all points rather than flow down the trail or be allowed to form puddles on it.

6. No flat Trails

If possible, a trail should always have a slight slope, either up or down. This allows water to flow off it rather than being allowed to form puddles. A no-flat trail will be dry within minutes after it stops raining.

7. Minimal Environmental Impact

Trails should be built with minimum environmental impact — good erosion control, no cutting of trees or roots, etc. A good trail will go around trees, preferably on the uphill side to minimise potential damage to the roots. Extra soil and rock can be added to roots to protect them from wear. Special care should be taken when passing through streams and wet areas such as using bridges, rock armouring or elevating the trail, etc.

8. Maximum Interest, Fun and Sustainability

A good trail will make the most of natural features like rock outcroppings, notable trees and other features (see illustration). In general, it should be routed to maintain a trail user’s interest. It should provide maximum fun to walk, run or ride without encouraging excessive speed by careful use of natural terrain features and direction changes. An area should have a selection of trails of different levels of challenge to cater to users of different interests and ability. Trails should be routed to avoid environmentally or culturally sensitive sites.

9. Natural Construction

Trails should only be built with natural materials, preferably those occurring in the vicinity. No concrete, steel or tarmac.

10. Maintenance

A well-designed and built trail requires less maintenance. But regular maintenance such as clearing deadfall, making sure drainage is working and cutting back encroaching undergrowth is needed.
