Managers are primarily responsible for checking on their field status - the county only monitors Park fields: ECL 5 and LLV. The league on occasion will make the call for all fields however, in most circumstances the managers will make the prudent call.
Coaches, parents, and others: When prepping fields for play or practice, do not sweep puddles into the grass as dirt goes along with it and do not remove any dirt (mud) from the fields as both these actions create holes from which future puddles are created. Should field be in this type of condition you probably should not be playing on the field. We know everyone has the best intentions, however please understand a lot of work has gone into these fields. You can help by dragging and raking fields following games/practices and filling in holes as necessary.
