Bike Park

Valmont Bike Park opened recently in Boulder Colorado. The multiuse bike space has elements for the youngest rider to the most advanced. Talk about a learning landscape and it looks incredibly fun too!

Check out this video for more info.

All of these photos are from, Thanks!

Longevity of wood in Natural Playscapes

Wood is such an important material in natural play. It can be used in endless combinations and configurations; climbing, walls, fences, loose parts, edging, seating, etc. But wood is, at its essence, a natural material that degrades and changes fairly quickly with use and time. How long a wood element in a playground will last depends on a lot of factors; is it touching the ground, how much wear will it get, how big is it, has it been treated, what is the local climate, and what is the intended use or actual use.

I would like to think that wood should be used in a capacity that it is allowed to degrade and change, further exemplifying natural processes. But, with safety requirements this seems more of a dream then a functional reality. I believe this striving for long lived materials is what resulted in the plastic, fiberglass, and steel pieces we see today.

I recently visited a natural playground in Tampa Florida. The playground was designed by The Natural Playground Company. If you have not seen their work you should! They were not involved in the construction, so final wood choices and details were completed by the contractor. Ethan King from The Natural Playgrounds Company told me the following.
 "We find a minimum of 5 years before any degradation occurs(on wood pieces), typically closer to 10.  That's only 5 years less than traditional equipment.  Furthermore, rotting logs don't cause splinters so there really isn't any kind of a significant safety concern."
Natural Playgrounds Company now treats all their products with a treatment called soy seal. They recommend treating wood ever 6 months in tough climates. I have been using Timber Pro's internal wood stabilizer for park and play elements.

The Tampa play space is set in a unique Cottonwood grove. As an Oregonian it looked very 'Florida'  with lizards, hanging moss, and an overall mangrove feel. Most of the elements are wood and the overall feel was magical woodland like. Today I am going to take a closer look at the wood elements.

From Natural Playgrounds

The following pieces seem to be constructed from lumber or dimensional piecesinstead of logs. Overall they seemed to be holding up well.

Coat rack: made from a 4" x4" and round pegs

Climber post - made from a 6" round (maybe a fence post) and 1" pegs. It could still hold my weight!
Storage Cabinet - dimensional 1 and 2 by material

Dimensional lumber trellis and swing.

I like to think that larger natural logs would last longer based on their size, protective bark, and unaltered state. The following pieces proved me wrong.

This piece was more of a landscape feature. I am not sure what it looked like going in, but it is definitely on its way to biodegrading.
These stepping logs looked rough! Ethan at Natural Playgrounds let me know these were not supplied by them. His guess is that they were not hard wood. The contractor probably supplied and installed these.

This wall looked good and stable. The small branch hand holds had all fallen or rotted off the climbing wall. This kind of detail looks great at first but obviously needs a little more maintenance then the dimensional pieces. I would argue in this case it is worth the extra time to update the hand hold detail to look and function like it did at installation.

In this case study the dimensional lumber held up a lot better than the natural logs and wood pieces. This may be because of their treatment, use, or installation. It makes me wonder if this is a wide spread result and if I would find the same thing in the pacific northwest. I guess I better keep looking around!

Does anyone have photos of wood play elements 5+ years after installtion? I would love to see them.

Risk and Safety a Nice Collection of Writings

I think it is the ever increasing concern for risk and liability that really got me interested in playground design. It is not enough it simply design a fun or education or inspiring children's space. The space needs to meet guidelines that have been developed through a lot of research and thought. Guidelines that make a very small and fairly safe box within which play can happen. I think the challenge of design within the safety guidelines but outside the box may be one of the main things that attracts me to playspace design. Well, it is fun too.

On one of my favorite blogs Let the children play, the author has but together a wonderful collection of links and views on safety and risk in play. It is worth a review if these topics interest you. Her list of resources is below.

::: Outdoor Play: Does Avoiding the Risks Reduce the Benefits? Helen Little and Shirley Wyver

The ultimate aim for parents, teachers and other play providers should be to provide outdoor play environments where the risks of serious injury are reduced, but creativity, challenge and excitement are maintained

::: Putting Risk into Perspective Tim Gill

Perhaps most important of all, we need to reflect on our own childhoods, and remind ourselves of what it might have felt like for Amma, when she climbed the tree in her nursery higher than ever before

::: Wild Things Clare Warden

‘Many children are not allowed to explore and test themselves in play and to feel in control of being “out of control”.’

::: Risk and Challenge: Essential Elements in Outdoor Play Spaces

::: Risks, Dangers and Hazards

Unfortunately, some early childhood educators and managers have responded to these factors by urbanising early childhood centres, with prefabricated, pre-built playspaces. Underlying this trend is a relinquishing of the responsibility for creating safe and engaging natural outdoor playspaces for children.

::: The Benefits of Risk in Playgrounds

When we become overly concerned with eliminating every potential bump or bruise on the playground, we also eliminate the potential for healthy lifelong developmental skills

I still believe children’s environments should be as safe as necessary, rather than as safe as possible. And I still believe that falling down is a normal part of an active childhood.
::: Just try to Stop Us @ Teacher Tom
Can a child hurt himself with a piece of string? If I let my brain run freely through my nightmares, I can come up with a few horrific possibilities, but realistically it ain't gonna happen.

Sorry for me blogging absence. My husband and I adopted a baby girl two months ago and my eyes, arms, and mind have been full of here ever since.
