COST BENEFIT ANALYSIS OF <br /> TURF VS. SYNTHETIC TURF SOCCER FIELDS <br /> Consideration: an adult sized field (210' x 360') wherein two youth fields (160' x 240') can be <br /> perpendicularly aligned at each end. Overall playing surface constructed is 260' x 380', <br /> providing playing surface extending 10' out of bounds. In acreage, 98,900 SF = 2.27 acres. <br /> ESTIMATE COMPARISON <br /> ITEM DRAINED TURF FIELD SYNTHETIC <br /> 1. Mobilization $5,000 $5,000 <br /> 2. Layout engineering 1,000 1,000 <br /> 3.

The capital costs per game are <br /> as follows, based on scheduling fields to their realistic potential: <br /> Turf field, drained $152,317 for 260 games = $585.83 per game <br /> Turf field, undrained $87,876 for 175 games = $502.15 per game <br /> Synthetic unlighted $406,670 for 756 games = $537.92 per game <br /> Synthetic lighted $585,170 for 1248 games = $468.89 per game <br /> On the maintenance end, the drained turf fields need irrigation, mowing, fertilizing, overseeding, <br /> sand top dressing and aeration. The synthetic fields need occasional regrooming. It is estimated <br /> that the regrooming is the cost equivalent of aeration, fertilizing and overseeding, and that the net <br /> savings amount to the costs for irrigation and mowing and sand top dressing. <br />
