The verdict is in and it's.....no verdict.
I was there yesterday and sat through the discussions between the judge and the racetrack legal team and the home owners legal team. They are at an impasse. The track is willing to suspend drag racing immedietely and build the wall, IF, the judge ruled that after the wall was built, the drag strip can go ahead full bore (including nostalgia fuel cars just like at Bakersfield). The home onwers say that if the wall will mitigate the sound problems, build it and if it works, great and if it doesn't, it's back to square one.
It's a catch-22 situation. It's foolish (and would be a poor business decision) for the track to spend upwards of a million bucks on a wall if it doesn't adequately protect the home owners, and there is no way to prove that it will, short of building the wall. The judge has specific sound measurment DB's he is working with and nobody is certain that the proposed wall will keep the noise under those DB's.
My experience of the judge after listening to him is that he is quite familier with drag racing, and the economics of the whole situation, but the acceptable noise level is still the acceptable noise level. As I understand it, these are state levels, not local or county levels
