Narrative:

My aircraft was given position and hold on runway 32, B737 Y cleared for takeoff on runway 1L. Runway 32 has 4250 ft to intersection, runway 1L has 6200 ft to intersection. I estimate B737 Y crossed runway 32 100-200 ft AGL. I was given takeoff clearance as the B737 Y crossed my runway, which I declined, and told the controller I wanted a 1 or 2 min delay for turbulence. He reissued the clearance about 1 min later, and I departed without incident, but , I did observe crossing runway 01L at about 200 ft AGL. I feel that an encounter with the B737 Y wake would have been uncomfortable at best and possibly catastrophic at such a low altitude. There has been much publicity about avoiding wake turbulence recently. I feel that local controllers should be more cognizant of the potential risks of close tolerance departures at intersecting runways.

Title: SMT X POSSIBLE WAKE TURB FROM B737 Y.

Narrative: MY ACFT WAS GIVEN POS AND HOLD ON RWY 32, B737 Y CLRED FOR TKOF ON RWY 1L. RWY 32 HAS 4250 FT TO INTXN, RWY 1L HAS 6200 FT TO INTXN. I ESTIMATE B737 Y CROSSED RWY 32 100-200 FT AGL. I WAS GIVEN TKOF CLRNC AS THE B737 Y CROSSED MY RWY, WHICH I DECLINED, AND TOLD THE CTLR I WANTED A 1 OR 2 MIN DELAY FOR TURB. HE REISSUED THE CLRNC ABOUT 1 MIN LATER, AND I DEPARTED WITHOUT INCIDENT, BUT , I DID OBSERVE XING RWY 01L AT ABOUT 200 FT AGL. I FEEL THAT AN ENCOUNTER WITH THE B737 Y WAKE WOULD HAVE BEEN UNCOMFORTABLE AT BEST AND POSSIBLY CATASTROPHIC AT SUCH A LOW ALT. THERE HAS BEEN MUCH PUBLICITY ABOUT AVOIDING WAKE TURB RECENTLY. I FEEL THAT LCL CTLRS SHOULD BE MORE COGNIZANT OF THE POTENTIAL RISKS OF CLOSE TOLERANCE DEPS AT INTERSECTING RWYS.
