Ah Rolling Hills... my high school home course (NLE) that I've clocked a few hundred rounds on (at least).
Some background on this project, which many thought would happen in 2006, not 2016. Rolling Hills formerly occupied a very small hilly property that wound its way between houses and the quarry mentioned in the article where the new course will mostly be.
According to the club site, this has remained the posted version of the layout for the last 3 years:
And here is the layout crudely overlaid and compared to the old course, as I knew it.
It is indeed surprising how under the radar this has been, however the above rendering does not inspire too much confidence, personally. If they are indeed sticking with the above routing, the southern-most 4 holes will not have the width most here would desire.
That said, it will still be a huge improvement over what was there before. Although a great course to beat our high school opponents on (teenagers have trouble figuring out that 3 iron is the play on par 4's, as was the case on the majority), the 6,200 yard, narrow, tree-lined course was not architecturally notable.
