Anyone know the details of the sand being pumped onto the beach at Rockaway and how it will affect the sand bars?

This flat spell has rough so today I headed to 90th street just to get wet and drop in on some shin high bombs. One of the lifeguards said they were "fixing the sand" and that the beach was closed and that only 67th street was accessible. The concept of God's ocean being "closed" really bothers me but whatever. Anytime the Army Corps of Engineers is involved, you gotta worry about a good wave being turned into a closeout lapping on the beach. Just curious if anyone knows the plan.
