Narrative:

While on approach under radar vectors from slc approach control, an RA was encountered around 12700 ft descending to assigned altitude of 11000 ft. Other aircraft was climbing out of slc near ffu VOR. The RA directed a descent of 1000-1500 FPM. After approximately 10 seconds conflict was over. I believe the controller misjudged our rate of turn and descent rate. I don't think departures should climb out through arrival traffic. Supplemental information from acn 386975: while turning through approximately 100 degrees we received a TA followed closely by an RA requiring 1000- 1500 FPM descent rate. In approximately 10 seconds clear of conflict was annunciated. I believe the controller misjudged the separation that would occur when issuing our turn and descent as the other aircraft was climbing after departing slc sbound. Supplemental information from acn 387933: vectored through runway 34R localizer when given a heading to intercept the runway 34R slc localizer and a descent from 14000 ft direct 11000 ft. Passing through at 13000 ft descending, a TA at 10 O'clock position, at 2.5 NM, 200 ft below climbing was noted. Very shortly an RA issued to descend at 1300 FPM. Conflict lasted about 10 seconds.

Title: A WDB DSNDING INTO SLC, UT, IS GIVEN A VECTOR FOR SPACING WITH A DEPARTING ACFT. AS THE WDB MAKES A TURN IT RECEIVES TCASII RA AND DSNDS TO AVOID THE TFC.

Narrative: WHILE ON APCH UNDER RADAR VECTORS FROM SLC APCH CTL, AN RA WAS ENCOUNTERED AROUND 12700 FT DSNDING TO ASSIGNED ALT OF 11000 FT. OTHER ACFT WAS CLBING OUT OF SLC NEAR FFU VOR. THE RA DIRECTED A DSCNT OF 1000-1500 FPM. AFTER APPROX 10 SECONDS CONFLICT WAS OVER. I BELIEVE THE CTLR MISJUDGED OUR RATE OF TURN AND DSCNT RATE. I DON'T THINK DEPS SHOULD CLB OUT THROUGH ARR TFC. SUPPLEMENTAL INFO FROM ACN 386975: WHILE TURNING THROUGH APPROX 100 DEGS WE RECEIVED A TA FOLLOWED CLOSELY BY AN RA REQUIRING 1000- 1500 FPM DSCNT RATE. IN APPROX 10 SECONDS CLR OF CONFLICT WAS ANNUNCIATED. I BELIEVE THE CTLR MISJUDGED THE SEPARATION THAT WOULD OCCUR WHEN ISSUING OUR TURN AND DSCNT AS THE OTHER ACFT WAS CLBING AFTER DEPARTING SLC SBOUND. SUPPLEMENTAL INFO FROM ACN 387933: VECTORED THROUGH RWY 34R LOC WHEN GIVEN A HEADING TO INTERCEPT THE RWY 34R SLC LOC AND A DSCNT FROM 14000 FT DIRECT 11000 FT. PASSING THROUGH AT 13000 FT DSNDING, A TA AT 10 O'CLOCK POS, AT 2.5 NM, 200 FT BELOW CLBING WAS NOTED. VERY SHORTLY AN RA ISSUED TO DSND AT 1300 FPM. CONFLICT LASTED ABOUT 10 SECONDS.
