Workers are building a stone wall around a Walt Disney World lake where an alligator killed a toddler earlier this summer.

Disney officials told the Orlando Sentinel for a story published Sunday that the barrier wall is part of the new security plan following the death of 2-year-old Lane Graves of Omaha, Nebraska. The boulder wall is going up along the beaches of the Seven Seas Lagoon where several resorts are located.

Disney also put up warning signs and ropes after Graves was dragged by an alligator into the lake on June 14. The boy's body was found 16 hours later and an autopsy showed he died from drowning and traumatic injuries.

The family decided not to file a lawsuit against Disney.
