Narrative:

Air carrier X requested a lower altitude than FL330 because of reported turbulence ahead. I coordinated with 2 slc sectors, and then cleared air carrier X to FL290. On the descent air carrier X may have violated the airspace of a third sector for about 3 mi and about 700 ft. Better sector boundary displays on sector maps and pvd's may have prevented this occurrence.

Title: OPDEV. UNCOORDINATED PENETRATION OF AIRSPACE.

Narrative: ACR X REQUESTED A LOWER ALT THAN FL330 BECAUSE OF RPTED TURB AHEAD. I COORDINATED WITH 2 SLC SECTORS, AND THEN CLRED ACR X TO FL290. ON THE DSCNT ACR X MAY HAVE VIOLATED THE AIRSPACE OF A THIRD SECTOR FOR ABOUT 3 MI AND ABOUT 700 FT. BETTER SECTOR BOUNDARY DISPLAYS ON SECTOR MAPS AND PVD'S MAY HAVE PREVENTED THIS OCCURRENCE.
