30 acres for a high school? something sounds wrong. How much of that is ACTUALLY TURF.
I think what the OP is saying is the ENTIRE property is 30 acres (plus 16 for the other properties) but there is parking lots, basketball courts, buildings etc.
How much is the measured turf??
I used to maintain Yale University, and they did not have 30 acres of turf to mow. I doubt this High School has that much mowable turf so that is the misconception we are dealing with here, sight unseen.
