The USGA Mid Am will be held at Charlotte CC in 2018. My Carolina GC will help out with qualifying medal rounds for two days. The USGA has specified [edit that to "suggested"] new mowing patterns for our course, which will be put in place next spring, more than a year before the event. I don't have the details, but we've been told that in general some of the fairways will be narrowed (boo! -- from me) and some of the chipping areas around the greens expanded. We do have pretty wide fairways now -- one result of which is that drives can run further off line and result in worse lines to the greens. Apparently this design feature does not appeal to the USGA, at least in some cases. We already have pretty large chipping areas around the greens.
In short, it will be interesting to see the result of the USGA's requirements [edit that to "suggestions"]. It will change the course somewhat, but whether it will be an "improvement" remains to be seen. Not to pre-judge, but while it may make the course somewhat more challenging for the expert golfers, if it makes less fun for the members, then it will not be an "improvement" (which is the downside of a club getting involved with this sort of event).
Our Superintendent has promised to post the changes per [sugested by] the USGA, and if he does so, I'll try to link to them.
As an aside, I'll be interested to learn if the USGA has any similar "suggestions" or requirements for Charlotte CC's course.
