A new development is starting along the north side our yard and there is going
to be extensive grading. What was 45 acres of hills and fields will now be
graded into sharp slopes with 1 acre flat pads on each 5 acre lot. Already
there have been huge tractors with spiked rollers out to clear the brush, which
had resulted in the horse trail, which was compacted and hard now being 6-9
inches of fine dust, which flies into the air at the slightest disturbance.
Needless to say, I'd rather the lot remains wilderness, but it looks like
progress will have it's way.

So I need to come up with a fast growing tall, thick hedge that will keep out
the dust as much as possible.

We're zone 9, southern California.

Any suggestions.
