In 1992, Robert Trent Jones oversaw an extensive renovation of the golf course. The course greens were replaced with Penn Links bent grass greens for smoother playability. The contours of six holes were modified to make the course more player friendly. The most extensive renovations were the relocation of the 11th green and building a new tee box for hole #8.

In April 2001, the Dunes Golf and Beach Club announced the completion of a $6 million renovation project which included modifications to the golf course. On the course, the driving range was expanded 30 yards in length and 40 yards in depth which more than doubled the number of stations from 18 to 40. This significant renovation has provided ample room for day-to-day practice and is now capable of servicing a full field tournament. In addition to the changes made to the driving range, golfers have noticed modifications to the 18th hole, where a new tee box was added. This new tee box offers an option of playing the par 4 hole as a dogleg left or playing from the original tees as a dogleg right. The club also added an extra hole to the course between the 13th and 14th holes. This “alternate hole” is substituted when another hole is closed for maintenance. It will guarantee that eighteen challenging holes will always be open for play. In December 2003 the course reopened after A-1 bentgrass was installed on the greens, replacing the Penn Links bentgrass. Rees Jones, the son of Robert Trent Jones, also restored all the greens to their original shape and made minor alterations to the first, eighth, 13th, 16th and 18th greens so as to remain consistent with the course’s original design. While the new greens are slightly faster than the old ones, they are still fair and challenging to players of all levels.
