"The field is a Kentucky Bluegrass irrigated field with a sand-soil root zone and an underground heating system containing nine boilers and 40 miles of underground piping. The heating system helps to keep the field from freezing and extends the growing season of the turf. Field has been designed to accommodate international soccer as well, with dimensions of 69 yards by 114 yards."
