Chip,
Rees was first hired in the 90's to oversee a bunker re-building project. At that time, he replaced many of the Gordon bunkers, which were sand-faced, with grass faces on the slopes. He did some other things, including some containment mounding that I do not care for, but to be fair, in the 90's he was NOT asked to restore, and the original plans were never considered. At the same time, we passed a resolution saying that any future changes had to be 1) recommended by our architect and 2) approved by a vote of the membership.
When we began our restoration process in 2005, Rees was given specific instruction to restore in the Banks style, and that is how he approached the project. I know he takes a beating here, but he and his lead guy, Keith Evans, really did a good job. In addition to putting back "Banks-style bunkers" they also recommended taking out mounding.
