I've noticed, on a few AWT and Ross courses, flanking or rear plateaus on par 3's.
These plateaus are below the level of the putting surface, usually on elevated greens with fairly steep banks.
They usually extend out for about 5 yards.
Their architectural intent seems to be to serve as a safety net for marginally errant approaches.
Without these plateaus, balls missing the green would be deflected by the slope, far beyond the putting surface and usually into a very difficult lie/situation making recovery to the green difficult to impossible.
I have not noticed their (plateaus) presence on par 5's and par 4's to the degree they appear on par 3's.
Did AWT or Ross or other architects write about the introduction of this feature ?
Is it mostly an ODG's feature.
Is it a feature whose function has been diminished by modern day irrigation systems ?
Mike Policano, one of the most notable of these plateaus is at the rear of # 6 West at RCC.
Where else have you seen this feature ?
On par 3's ?
On Par 4's ?
On Par 5's ?
Has the incorporation of this feature into the green surrounds become a lost art ?
