Narrative:

2 minor problems, no violation, no near miss, no runway incursion. Taxi difficulties and lgb are one thing in the same, knowing this I had the runway diagram on yoke. Taxi from the FBO to runway 25L at taxiway D intersection for takeoff. Plate was reviewed. Simple except progressive instructions were required due to taxiway D at runway 25L not marked. If you look at the plate taxiway D and runway 34R at the east end of taxiway F, the expanse of pavement here is unmarked, with such close proximity to runway 30 it is a busy place. Is it possible to mark this more clearly? Next time I'll know, but I couldn't have been better prepared. Clearance delivery instructed me to depart runway 25L at taxiway D, depart east to the highway 91/605 interchange at or below 2500 ft MSL. The problem is if I turn downwind on runway 25L to the east as instructed I will not end up at the 91/605 interchange due to this confusion I requested takeoff clearance left downwind departure which would have sent me east as instructed. Once airborne I was first instructed to do a left 270 degrees, then a right turn to a heading of northeast which did put me over the 91/605. The problem is that I would have preferred more specific instruction from clearance delivery. I normally fly IFR to avoid these problems yet on a pristine summer night I thought this unnecessary. Maybe from flying IFR so much I expect specific instructions. I am a CFI and can't imagine how a low time pilot might handle this situation. I can fly the airplane any way they want, but I need to know.

Title: CFI RATED PLT OF C172 IS FRUSTRATED WITH CONFUSING CLRNCS AND INSTRUCTIONS FROM LGB TWR.

Narrative: 2 MINOR PROBS, NO VIOLATION, NO NEAR MISS, NO RWY INCURSION. TAXI DIFFICULTIES AND LGB ARE ONE THING IN THE SAME, KNOWING THIS I HAD THE RWY DIAGRAM ON YOKE. TAXI FROM THE FBO TO RWY 25L AT TXWY D INTXN FOR TKOF. PLATE WAS REVIEWED. SIMPLE EXCEPT PROGRESSIVE INSTRUCTIONS WERE REQUIRED DUE TO TXWY D AT RWY 25L NOT MARKED. IF YOU LOOK AT THE PLATE TXWY D AND RWY 34R AT THE E END OF TXWY F, THE EXPANSE OF PAVEMENT HERE IS UNMARKED, WITH SUCH CLOSE PROX TO RWY 30 IT IS A BUSY PLACE. IS IT POSSIBLE TO MARK THIS MORE CLRLY? NEXT TIME I'LL KNOW, BUT I COULDN'T HAVE BEEN BETTER PREPARED. CLRNC DELIVERY INSTRUCTED ME TO DEPART RWY 25L AT TXWY D, DEPART E TO THE HIGHWAY 91/605 INTERCHANGE AT OR BELOW 2500 FT MSL. THE PROB IS IF I TURN DOWNWIND ON RWY 25L TO THE E AS INSTRUCTED I WILL NOT END UP AT THE 91/605 INTERCHANGE DUE TO THIS CONFUSION I REQUESTED TKOF CLRNC L DOWNWIND DEP WHICH WOULD HAVE SENT ME E AS INSTRUCTED. ONCE AIRBORNE I WAS FIRST INSTRUCTED TO DO A L 270 DEGS, THEN A R TURN TO A HDG OF NE WHICH DID PUT ME OVER THE 91/605. THE PROB IS THAT I WOULD HAVE PREFERRED MORE SPECIFIC INSTRUCTION FROM CLRNC DELIVERY. I NORMALLY FLY IFR TO AVOID THESE PROBS YET ON A PRISTINE SUMMER NIGHT I THOUGHT THIS UNNECESSARY. MAYBE FROM FLYING IFR SO MUCH I EXPECT SPECIFIC INSTRUCTIONS. I AM A CFI AND CAN'T IMAGINE HOW A LOW TIME PLT MIGHT HANDLE THIS SIT. I CAN FLY THE AIRPLANE ANY WAY THEY WANT, BUT I NEED TO KNOW.
