To expand on my previous post, the ditch added to the fifth hole at Saratoga was inspired by places like Royal Worlington and Swinley Forest and created an interesting "hazard" that gets in players heads, but as a grass ditch, can also be be played out of. The great part was, within days of its creation, it dried up a green area that had been a quagmire for as long as anyone could remember, and it is way cooler than any catch basin and pipe will ever be!
As a bonus, beyond improving the turf conditions by drying up that area, it allowed an unsightly and annoying cart path to be removed near the green, as the area is now dry enough for cart traffic without the the path.
The mounds we created were primarily built with old dirty bunker sand we removed while redoing the bunkers. Among other things, it allowed us to create extremely economical, period appropriate and textured hazards ( course was originally built in 1897) with virtually no maintenance cost, while providing/ keeping separation between holes after removing a bunch of trees that destroyed views and created uninteresting one dimensional golf.
