Is there an "idle" speed for the web?

Is there a web site which lists every speed limit on every street in Los Angeles?

• My friend just got a ticket and the police officer informed him the speed limit was 30, not 35, even though it appeared to be clearly a commercial street. Short of going to Los Angeles City Hall, and manually researching the maps etc, is there a site that lists all the speed limits, or is there a streamline approach to research the posted speed limits?
