As police were determining the death of Kyzr Willis, 7, was a tragic accident, the mayor's office was announcing changes to the way the Curley Community Center in South Boston runs its summer program for kids, when they re-open on Monday.
Staff will be required to conduct headcounts every hour - and when children move through entrances and exits.
The center will be required to have at least two counselors on duty for every 10 kids under 6 and two counselors for every 10 children 7 or older.
Children will be organized into lines before being moved from one activity location to another, with a counselor at the front and back and a third to walk alongside the line.
All children will be required to wear life vests while in the water. Only 10 children will be allowed in the water at one time - and they have to be accompanied by at least two counselors.
The city will install 34 new security cameras at the Curley center by Tuesday.
The headcount procedures, child staff ratio and line supervision procedures will be enforced broadly across all BCYF drop-in programs across the city. All counselors are banned from using phones and other electronic devices during their shifts, unless required in an emergency - or while they're on break.
