Good irrigation systems can't be over-emphasized. The trend is toward completely automated systems. Installing an irrigation system is a relatively simple procedure. An automatic system can conserve water, reduce labor expenses and allow watering during night-time hours. More and variable pin placements are possible with larger greens and alleviate problems caused by heavy play.
Gentle undulations permit the use of tri-plex mowers and reduce the risk of scalping.
The green should be designed, if possible, to drain in more than one direction. It is possible to enlarge a green, but the best way is to reconstruct it entirely. It is less a task to install additional drainage than is supposed. Critical areas can be retiled and backfilled, and the sod replaced within one day. Many courses find a detailed planting program an excellent method for replacing maturing trees and supplementing existing plantings.
