A displaced threshhold is also in use at LAX on the 25's.
In my opinion, busy Airport Blvd. would be much too close to for landings, if if the runway east of Foxtrot were used. Only take offs are aloud.
It is also used at runway 6R just east of echo 17. In this case I believe it is because of the proximity to Pershing Ave. and the dunes/knoll to the west, which actually used to be houses back in the day.
