After inspection and approval of rg eens by Owner, apply seed material and rake in. DO NOT seed until irrigation water is available at each green. Page Four ]3. Greens are to be kept moist at all times once watering starts. Greens shall be mowed where grass is 1/2" to 3/4" tall. Mower height is to be 1/2"• 14. Retain and protect all underground sprinklers and sprinkler piping. 15. Seeding of green embankments and approaches shall be with the same seed mixture as the fairways. These areas shall be seeded 40 feet from the greens in all directions and before watering of the greens begins. 16.

DetaileC drainsge•system plan for a putting green, Installation of Subsurface system Typically, the system.consists of 15- to 20- foot lateral spacing of drain lines.in herringbone arrangement. The drain lines are 4 inches in diameter and of flexible corrugated drain pipe. The plastic drains have gained wide acceptance due to their ease of installation and comparatively low cost. The collection pipe is PVC drain. The first phase in installation involves siting, surveying and staking of drainage lines, and proper labeling for desired depth of cut. The trench should be no deeper than is necessary to achieve the needed slope for proper drainage. The suggested minimum fall is 0.5 percent; the range is up to 3 or 4 percent. The, trench width and depth shall be 8". The soil .dug during trenching may be distribute 'over the subgrade in a manner which establishes a crown between the drain lines or it may be removed from the site. A 2 inch layer of gravel is placed in the bottom, of the trench before the drain lines are put down. Prior to back- filling, all main and lateral lines should be checked with a level to insure that the grade or fall provides adequate drainage. On colllction of drain line installation,~including appropriate tees and end caps, the trenches are backfilled with 1/2" gravel. It is important to avoid displacement of joint coverings during backfilling. This usually involves shoveling of gravel on the joint covers, tee, and connections before backfilling is completed with mechanical equipment: CHERRY LANE GOLF COURSE GREEN CONSTRUCTION GENERAL CONDITIONS The Contractor who is installing the new "greens" and his subcontractors and their subcontractors shall be bound by the following General Conditions.
