The Bellmore-Merrick Central High School District is closing all school fields, effective April 2.
The fields have been open to the public amid the coronavirus outbreak, but groupings that were not following state guidelines have been spotted in the areas in recent weeks.
Use of the tracks will still be permitted as long as social distancing guidelines — 6 feet of space — are adhered to by walkers and runners alike, according to a letter to parents from Superintendent John DeTommaso.
Security will continue to monitor all fields seven days a week.
"Please know, that the BMCHSD Board of Education and I understand how incredibly difficult this whole crisis has been on all of our families," DeTommaso wrote. "We sincerely hope that our school fields can be opened up to the community in the not-so-distant future. We are all looking forward to seeing all of you again very soon."
