I'm planning to make public meetings and the like, but since I live in Oakland
and work in Marin, it's hard to commit 100% ahead of time. I think we should
put together a coordinated response to the draft EIR and if everyone likes it
we can present it as representing the community. A united front presenting an
intelligent analysis that is relevant to the issues as they are dealt with in
the planning process goes much farther than just presenting lots of bodies and
making emotional pleas.

I imagine a report with the following format:

1) describe why Coyote is a irreplacable resource for windsurfing

2) Challenge definition of 'significant impact' as being a reduction in wind
velocity of 10% or more.

3) Suggest another definition of significant impact

4) Challenge methodology/results of wind tunnel test

5) Suggest another means to estimate impact of buildings

6) Suggest mitigation Measures

It will be tough to come up a quantifiable definition of 'significant impact',
but that is the type of thing planning commisions want to see before they
force people to change designs or pay for mitigation. If we are going to pick
a percentage chnage in velocity, maybe 20-25% is more reasonable since that is
roughly ( in my estimation) the amount of change in wind velocity that pushes
one up or down a sail size.

Since we can't throw up an 11 story test building on a windy day, we need a
physicist/engineer type to challenge the consultants model or make our own
model. I am going to call some of the University's that have wind engineering
programs and see if any professor can be drawn in enough at least read the
draft EIR out of curiosity and go from there. If the model is bad science,
maybe we can find somebody with credentials to say so. If anyone has another
expert lead, go for it.

The only other way I can think of to estimate impact is to look at real world
cases like the hotel project in Aruba. Any other real world cases?

This is where we might have to rely on citing real world cases such as the the
hotel erected upwind in Aruba for lack of a way to quantif

- suggest another definition although it is tough to quantify.
- point out that beyond velocity there are issues of turbulence.
- point out that reduced wind velocity creates greater difference between
velocity at beach and velocity in channel which means more people over-rigged
outside (breaking gear or getting injured) or under-rigged inside (swimming
home).
