Boise's historic River Club is being rebuilt by architect Brian Curley, and its new bunkers will be lined using the ZLine system.

Boise, Idaho, April 21, 2026 - Boise's River Club was originally known as the Plantation Country Club and founded in 1917 - it is the oldest golf course in southern Idaho.

Like many older clubs, it is constrained by its surroundings, bordered by the Boise River on one side and State Street on the other.

At 120 acres, the site is relatively tight for a modern golf course. When the course changed hands in 2018, the new owner proposed selling some frontage along State Street to fund improvements, requiring a creative design approach.

The club has already upgraded its swimming pool and added pickleball and bocce ball courts. Architect Brian Curley was brought in to reconstruct the golf course, shortening the layout so that the previous middle tee yardage becomes the new back tee length. Par will be reduced from 69/70 to 68, with redesigned holes intended to create a more engaging playing experience.

Construction is now underway and, due to a mild winter in Boise, the project is ahead of schedule.

The course's new bunkers will be lined using the ZLine system. Course superintendent Nate Cahill said the product was selected primarily for its ability to prevent contamination of bunker sand.

"Being right alongside the Boise River, we have river rock in our soil, and it finds its way into our bunkers," Cahill explained. "The selection of ZLine was mostly about preventing that, though its ability to move water away quickly when we get rain events was also an issue."

"Some other bunker liners have a fairly narrow installation window in terms of weather conditions - we can install ZLine in any weather. ZLine came out and trained the team in about a day and a half, and about three-quarters of our new bunkers have already been lined."

"It is a very straightforward product to install, which makes our life a lot easier. There is plenty going on, so not having to worry about the bunker liner is a good thing."
