WARNING UNIT (THE DOMES AND THE ENTIRE 24"

LEVEL SURFACE) IS FOR ILLUSTRATION ONLY.

DETECTABLE WARNING UNIT DIMENSIONS:

THE SIZE OF THE DETECTABLE WARNING FIELD SHALL BE

24" IN THE DIRECTION OF TRAVEL AND SHALL EXTEND

THE FULL WIDTH OF THE CURB RAMP OR FLUSH SURFACE,

EXCLUSIVE OF SIDE FLARES.

DOME ALIGNMENT:

THE ROWS OF DOMES SHALL BE ALIGNED TO BE

TO A RAILROAD CROSSING SHALL BE 6'-0" MINIMUM AND

15'-0" MAXIMUM FROM THE CENTERLINE OF THE NEAREST

RAIL.
