permission to build jumps by council but what to build

[greasy reas]

just wondering if any one had a link to some information about dirt jumps to represent to a council. im looked at the the posts above and printed some pages off. the reason for this next tuesday some friends, parents and i have a meeting with the council about jumps being built in kangaroo valley. we have got permission to build there but the jumps need to be safe in council sense and they do not believe our jumps are safe and we are havng the meeting to discuss with them if they will help us build them with machinery. one point we are trying to bring up is the dumping of dirt to make table tops so novice riders can ride there and still jump. dont know if anyone is familier with tahmoor jumps but we are going to try to get a jump park built like that. manly after suggestions and ideas/ plans to present to the council on what would be the best way to have/ make the jumps. eg pis or diagrams of other jump parks

Search for Adelaide City Jumps. If you find something let me know. I used to have some amazing photos (somewhere....)
MTBA might also be able to help, have you tried them? What about local MTB clubs?

The approach that we'll be taking soon with land owners is to grade the jumps, same as you would with any technical trail and to very clearly signpost them with their gradings. You know, the green circle beginner stuff, blue square intermediate level, black diamond advanced level and double black diamond expert level.

If you have the space avaialble, make 4 sets. Beginner should all be low (1 foot or so) with rounded lips and totally rollable and all tabletops so that if you come up short you're okay.

Your intermedates should again be all tabletops but taller (2.5 feet?) with squarer lips.

You can put your 3 foot and up to 4 foot doubles in your black diamond run and your over 4 footers in the double black diamond.

Make sure that each run is clearly signposted and that you make it clear that dirtjumping has the potential to cause injury and that people should not attempt the advanced and expert runs unless they are sure of their capabilities (and that in doing so, they are intentionally and voluntarily taking part in an activity that has the potential to cause injury). Talk to your council about any skate parks they may have built and see what sort of legislation underlies the risk of injury for those facilities. It should be very similar.

I realise that putting in tabletops uses up a hell of a lot of dirt but it's really the only way to make beginner level jumps safe. The council may be able to help you out with supplying dirt so you don't have to dig every cubic foot out of the ground.

It seems that one of the biggest hassles councils have with dirt jumps is that unlike a skate park, dirt jumps can be modified by anyone once they've been approved and built. Try and establish a contact officer at the council and make sure that you inform them about any changes to the plan you intend to do at a later date (before you do it).

The advantage of spending your time putting beginner and intermediate lines in is that you won't have squids trashing the bigger lines to make them rideable.

Definitely check the Adelaide stuff. Brilliant city supported jump park that is maintained by the riders.
