Narrative:

Upon departure from ont, prado 6 departure, we were given a vector off the departure that took us near an area of parachute operations. Socal departure, frequency 134.0, assigned us 13000 ft due to 4 parachute jumper aircraft at 14000 ft. The frequency was so saturated that the controller said something to the effect of, everyone listen, nobody talk. our TCASII display showed one of these parachute jumper aircraft at approximately 2.0 mi and descending (approximately 13800 ft) when we received an RA to, descend, descend. it appeared on the TCASII display that the aircraft was coming our way. Due to haze and smog, we never visually acquired the aircraft. We responded to the RA and descended to approximately 12000 ft. When we were able to get on the very congested frequency to notify the controller of our RA, he responded with something like, yeah, thatsouth the traffic I told you about. it seemed by his tone, that this was normal operations to have air carriersouth and parachute jumpers this close. I feel this is a safety concern to vector air carriersouth close to a known area of frequent parachute jumping. I also feel that the congestion on the frequency meant that this controller had an unusually high workload.

Title: B737 DEP FROM ONT EXPERIENCED TCASII RA WITH JUMP ACFT WHILE ON VECTORS FROM SCT AT 1300 FT.

Narrative: UPON DEP FROM ONT, PRADO 6 DEP, WE WERE GIVEN A VECTOR OFF THE DEP THAT TOOK US NEAR AN AREA OF PARACHUTE OPS. SOCAL DEP, FREQ 134.0, ASSIGNED US 13000 FT DUE TO 4 PARACHUTE JUMPER ACFT AT 14000 FT. THE FREQ WAS SO SATURATED THAT THE CTLR SAID SOMETHING TO THE EFFECT OF, EVERYONE LISTEN, NOBODY TALK. OUR TCASII DISPLAY SHOWED ONE OF THESE PARACHUTE JUMPER ACFT AT APPROX 2.0 MI AND DSNDING (APPROX 13800 FT) WHEN WE RECEIVED AN RA TO, DSND, DSND. IT APPEARED ON THE TCASII DISPLAY THAT THE ACFT WAS COMING OUR WAY. DUE TO HAZE AND SMOG, WE NEVER VISUALLY ACQUIRED THE ACFT. WE RESPONDED TO THE RA AND DSNDED TO APPROX 12000 FT. WHEN WE WERE ABLE TO GET ON THE VERY CONGESTED FREQ TO NOTIFY THE CTLR OF OUR RA, HE RESPONDED WITH SOMETHING LIKE, YEAH, THATS THE TFC I TOLD YOU ABOUT. IT SEEMED BY HIS TONE, THAT THIS WAS NORMAL OPS TO HAVE ACRS AND PARACHUTE JUMPERS THIS CLOSE. I FEEL THIS IS A SAFETY CONCERN TO VECTOR ACRS CLOSE TO A KNOWN AREA OF FREQUENT PARACHUTE JUMPING. I ALSO FEEL THAT THE CONGESTION ON THE FREQ MEANT THAT THIS CTLR HAD AN UNUSUALLY HIGH WORKLOAD.
