Post general kiteboarding discussion topics here!
Ok as a 3rd kiter for more than 10 years I want to point out a topic up we like to ignore - or at best dont want to think about. The 3rd upper launch eroded dramatically over the years. Now, as google earth offers a time sider and a ruler I measured the beach length of their images 1993 to 2012.
So here we have the 93 image
and here the 2012
now with the line tool I measured the minimum beach length of the cove to the stones. So we get this graph.
We loose 9 meters per year. And quite linear. With the remaining 31 meters minimum we have till 2016 when the cove actually will touch the stones. We have to act either with the city or without. Now what do you think is the option of choice?
I totally agree that we need to do something and am willing to help. Every year this comes up, and every year a few naysayers jump in to say we can't do anything without the city and talking to the SFBA about what they are doing, blah, blah, blah... I'm all for following protocol but not at this pace. I rather ask for forgiveness than permission in this instance. As pointed out, we won't have upper launch for much longer if we don't take action.
Does anyone have any erosion control experience? What needs to be done? Two lines of sandbags? One at the line shown in 1993 and another close to the current line?
I am familiar with this type of work.
You would have to get numerous environmental impact studies done, draw up plans, get permits, find funding, get a licensed company to perform the work, have it inspected... etc etc etc.. i wouldn't hold your breath.
If a sandbag or two a day and some carpet mysteriously appeared to create a barrier it likely would be done faster. It would require thousands of them to even halt the erosion much less reverse it and would be illegal
Rip rap encased in wire mesh and/or bay dredgings dumped there strategically would be the real fix. Then maybe a nice lawn area and entry ramp to turn it into a real Kite Park. Millions of and years to do.
Unfortunately thats the reality of it.
just saying... wait.. i didn't say that

Ditto on loscocco's comment. A not insignificant effort that holds at least several years of committed work and some money to consider.
G - I believe there are multiple jurisdictions involved, have a check in with the SFBA folks.
