Signs are popping up in some Arlington County parks telling patrons to play elsewhere. The signs simply read “Field Closed” — but there are no other measures to keep residents away from that portion of the park. So what gives?

Department of Parks and Recreation spokeswoman Susan Kalish said workers post the signs in some of the county’s sports fields and parks during the winter to allow the turf to rest. The signs are intended to discourage larger gatherings and sports games on the affected fields.

“It’s not like we don’t want people walking through the areas, but we want to discourage pick-up soccer games and things that could stress the grass,” said Kalish.

Kalish said because grass doesn’t grow at this time of year, any damage that would be done to turf during the winter wouldn’t be able to begin mending until spring. Preventing winter damage from occurring in the first place cuts down on the amount of mending necessary in the spring.
