First officer of a B737-300 complains of the noise abatement procedure out of lgb that conflicts with the VFR corridor flown by VFR traffic transiting the lax TCA class B airspace. Had an near midair collision while on a vectored climb southwest of lgb with a C172.

Narrative:
Our clearance out of lgb was runway heading to 1500 ft MSL, left turn heading 180 degrees. After completing the turn to 180 degrees, retracting the flaps and contacting socal departure, the controller advised traffic 12 O'clock and 2 mi. When we reported no contact, he called for a heading of 210 degrees. Rolling out on that heading, we received an RA from TCASII to 'reduce climb, monitor vertical speed.' I swung my head right (as non flying first officer) and saw the C172 at 4 O'clock and slightly above us. I could almost make out the numbers on his fuselage. The lgb noise abatement procedure and the socal VFR corridor do not mix and designers need to rethink both. Sna departures into the corridor cannot be helped, but lgb is a different story.
Original NASA ASRS Text
Title: FO OF A B737-300 COMPLAINS OF THE NOISE ABATEMENT PROC OUT OF LGB THAT CONFLICTS WITH THE VFR CORRIDOR FLOWN BY VFR TFC TRANSITING THE LAX TCA CLASS B AIRSPACE. HAD AN NMAC WHILE ON A VECTORED CLB SW OF LGB WITH A C172.
Narrative: OUR CLRNC OUT OF LGB WAS RWY HDG TO 1500 FT MSL, L TURN HDG 180 DEGS. AFTER COMPLETING THE TURN TO 180 DEGS, RETRACTING THE FLAPS AND CONTACTING SOCAL DEP, THE CTLR ADVISED TFC 12 O'CLOCK AND 2 MI. WHEN WE RPTED NO CONTACT, HE CALLED FOR A HDG OF 210 DEGS. ROLLING OUT ON THAT HDG, WE RECEIVED AN RA FROM TCASII TO 'REDUCE CLB, MONITOR VERT SPD.' I SWUNG MY HEAD R (AS NON FLYING FO) AND SAW THE C172 AT 4 O'CLOCK AND SLIGHTLY ABOVE US. I COULD ALMOST MAKE OUT THE NUMBERS ON HIS FUSELAGE. THE LGB NOISE ABATEMENT PROC AND THE SOCAL VFR CORRIDOR DO NOT MIX AND DESIGNERS NEED TO RETHINK BOTH. SNA DEPS INTO THE CORRIDOR CANNOT BE HELPED, BUT LGB IS A DIFFERENT STORY.
