There has been much discussion surrounding the new pot bunker that was built on #18 over the last winter. The bunker was put in with the concept of it being a true hazard, and to force players to make a decision with respect to their lay-up shot on the finishing par-5. With it's placement in the 120-130 yard landing area it more than accomplishes the goal of making players think long and hard about the strategy of how to play their finishing hole.
One thing most people other than the Chambers Bay maintenance staff hasn't thought of, is how the ten foot deep bunker with short-mowed turf extending down the vertical walls was going to be maintained. Here's a couple of pictures that start to explain the challenges this bunker presents which have nothing to do with golf.
Some of the other maintenance plans for Chamber's Basement include the installation of low-precipitation landscape irrigation heads around the top edge to help with the irrigation issues we're facing with regards to this unique section of the course.
