After unsuccessful attempts to keep the Islanders in Nassau County, they left the Coliseum, their home since joining the NHL in 1972, when their lease expired following the 2014-15 season and moved to Barclays Center in Brooklyn. The Coliseum has experienced a $165 million renovation and holds 13,900 fans for hockey, down from 16,234 prior to the move.
In January, it was announced the Islanders would return to their original home for 60 games (now 61; their game against the Toronto Maple Leafs on Feb. 28 has been moved from Barclays Center) through the 2020-21 NHL season. New York state then committed $6 million in enhancements at the Coliseum to meet NHL requirements, specifically investing in ice plant redundancy and dehumidification, and media and broadcasting cabling infrastructure.
The Islanders, who are scheduled to move into a new arena at Belmont Park in Elmont, New York for the start of the 2021-22 NHL season, contributed an additional $4 million to renovate their locker room and facilities.
