SFO GND CTLR DESCRIBED POTENTIAL RWY CROSSING INCIDENT WHEN INTRAFAC COORD WITHIN THE CAB FAILED.

Narrative

MD80 COORDINATED TO USE TXWY Z AFTER A CITATION DEPARTED RWY 28R. WHEN CITATION WAS AIRBORNE AND I WAS GOING TO ISSUE INSTRUCTIONS TO MD80; I OBSERVED CRJ2 POSITIONING ON RWY 28R; WITH TFC ON 5 MI FINAL. I CONFIRMED WITH CAB COORDINATOR; WHO MADE ORIGINAL COORD; WHO SAID YES CROSS W END NOW. AS I BEGAN ISSUING CLRNC; THE CRJ2 BEGAN DEP ROLL. RADAR COORDINATOR THEN ALERTED LCL CTL THAT TFC WAS CLRED AROUND THE W END. AS LCL CTL CANCELED CRJ2 TKOF CLRNC; I WAS ABLE TO STOP MD80; SO NO ONE ACTUALLY CONFLICTED. POSSIBLE FACTORS: 1) IN MY OPINION THIS WAS A SITUATION WHERE DURING LIGHT TFC TOO MANY POS WERE OPEN; TOO MANY PEOPLE INVOLVED. I BELIEVE HAD I DONE THE COORD WITHOUT A COORDINATOR PRESENT IT WOULD HAVE STUCK BETTER IN THEIR MEMORY. 2) THE LCL CTLR; MYSELF; AND THE CAB COORDINATOR WERE ALL ON FIRST POS OF THE WORK WK AFTER OUR WEEKEND; AND IN OUR FIRST HR OF WORK OF THE WK. 3) THE INCONSISTENT USE OF TXWY Z BY ALL THE CTLRS. BECAUSE OF THE FAA AND ARPT ARE UNWILLING TO MAKE MANDATORY THE USE FOR ALL ACFT TO GET ACROSS RWY 28L/R.
