For Fontana, here is the short version.
The 1/4 mile track used to be on the south side of the property, but they moved it to the north side of the property back in 2005. The track owners obviously got approval to do the move, but a tiny number of residents and businesses started complaining about the noise.
What I can't wrap my head around is the following---a couple sets of rail road tracks are in-between the track and the effected nearby houses, businesses. Also, these houses and businesses are in an industrial zoned area. There is far more noise generated EVERYDAY by the metro link and freight trains because of the railroad crossing that is a little bit further east then the starting line.
Add to the fact that the PSCA events only run 5 times a year. The monthly street legal drags are for street cars that don't make any noise that the residents can hear. They compromised a few times, by having a decibel meter at one of the properties, and PSCA hasn't ran the PRO ant TT5 cars for a couple years. Now the county wants an environmental impact study and a sound wall built---and until the environmental impact study is done, no more racing of any kind.
That is to the best of my knowledge what is going on at this track.
Famoso (Bakersfield--McFarland actually) I sure is safe for many more years, surrounded by farmland. Barona in on Indian reservation land, so no worries there. And Vegas certainly isn't going anywhere.
I wish I could move to Texas or somewhere back east. All of the major drag races are back that way with plenty of tracks. Taxes and housing prices are less to almost anywhere else.
Here is a few pictures of the track where the railroad tracks are right on the other side of the banners on the fence. The railroad tracks are heavily used. The area on the other side of the railroad tracks is where the complaints are coming from, and that is an industrial zoned area, with even a huge recycling center for scrap metal.
