These standards are based on a classification system (1-5) for the athletic field which is primarily based on the root zone material and the provision of drainage, irrigation and lights. Includes permitting hours and maintenance costs for field categories; a checklist to evaluate the condition of existing fields; and more than 20 diagrams outlining the approved field dimensions for most field sports using a turf surface.
