I got an altemiter from my son and had some bussiness in Irwindale so i stopped by the drag strip and measured the altitude at the starting line and finish line. I stayed 20 min at each place to get an avg.
Starting line.....383 ft above sea level
Finish line........375 ft above sea level
avg it out........379 ft above sea level

I did a google and came up with 750' above sea level.

You probably already know this, but the factory REC navigation systems display elevation. I don't know about the RER's.

Yes theres about 4-5 diff weather site and there all diff altitudes so thats why i got the altemiter. The weather site i use measures the temp 1 mile from the drag strip and says its 420 so its got to be close.
