Narrative:
The lax class B airspace has a northeast corner that always creates a problem when descending from the ese to bur or vny. A victor airway (V186) cuts through the corner but has a floor of 4000 ft, a top of 12500 ft and an MEA of 5000 ft. High mountains are to the north and sometimes turbulence spills over them. On top of trying to avoid this corner, approach is concerned with big jets descending from the northeast which are in conflict with aircraft able to cruise at night altitudes and subsequently descending in this same airspace to the east of the lax class B. Trying to navigation around this tight corner with the distraction of multiple 'heavies' to look for can easily put a VFR flight (even with advisories but no class B clearance) into this class B corner. Things are moving fast at 200 KTS. I'm not sure I missed this corner or not! It's too tight and should be redesigned.

Title: PLT RPT OF POSSIBLE ENTRY INTO CLASS B NEAR VNY, BUR, CA. RPTR CITES AIRSPACE DESIGN AS PROB DURING TFC WATCH AVOIDANCE PERIODS.
Narrative: THE LAX CLASS B AIRSPACE HAS A NE CORNER THAT ALWAYS CREATES A PROB WHEN DSNDING FROM THE ESE TO BUR OR VNY. A VICTOR AIRWAY (V186) CUTS THROUGH THE CORNER BUT HAS A FLOOR OF 4000 FT, A TOP OF 12500 FT AND AN MEA OF 5000 FT. HIGH MOUNTAINS ARE TO THE N AND SOMETIMES TURB SPILLS OVER THEM. ON TOP OF TRYING TO AVOID THIS CORNER, APCH IS CONCERNED WITH BIG JETS DSNDING FROM THE NE WHICH ARE IN CONFLICT WITH ACFT ABLE TO CRUISE AT NIGHT ALTS AND SUBSEQUENTLY DSNDING IN THIS SAME AIRSPACE TO THE E OF THE LAX CLASS B. TRYING TO NAV AROUND THIS TIGHT CORNER WITH THE DISTR OF MULTIPLE 'HEAVIES' TO LOOK FOR CAN EASILY PUT A VFR FLT (EVEN WITH ADVISORIES BUT NO CLASS B CLRNC) INTO THIS CLASS B CORNER. THINGS ARE MOVING FAST AT 200 KTS. I'M NOT SURE I MISSED THIS CORNER OR NOT! IT'S TOO TIGHT AND SHOULD BE REDESIGNED.
