Those are different routes altogether. The SFRA passes directly over LAX
between Santa Monica and Long Beach. It does not require ATC approval or
even ATC contact. You're right, however, that the LA TAC shows the route
and gives the procedures for using it. In fact you have to have the TAC in
your possession legally to fly the route.
