I'm a contractor working on a project for a state agency. We are compiling lists of data sources for socioeconomic information specific to the California Delta. The information about location of airports, number of planes, number of flights is helpful in doing project impacts analysis in the Delta. I'd appreciate contact from an administrator or knowledgable official that can help me answer some questions.

despite the name airport-data, we don't have that kind of FAA related information. This is mainly an aircraft spotter/hobbiest site, not an actual site that could give you complete info about airports.
Your best bet for what you are looking for is to go to Airnav.com and then enter the various California airport codes. For example here is Van Nuys -
