Climate Pledge Arena is the oldest arena in the NHL.

The arena was previously most notable as the long-time former home of the [[Seattle SuperSonics]] of the [[National Basketball Association]] (NBA). The SuperSonics first played at the facility, then known as the '''Seattle Center Coliseum''', from their founding in [[1967–68 Seattle SuperSonics season|1967]] to [[1977–78 Seattle SuperSonics season|1978]]. After a seven-season stint in the higher capacity [[Kingdome]], they returned to the arena in [[1985–86 Seattle SuperSonics season|1985]]. The facility underwent an extensive renovation after the [[1993–94 Seattle SuperSonics season|1993–94]] season, which necessitated the relocation of SuperSonics home games to the [[Tacoma Dome]] for the [[1994–95 Seattle SuperSonics season|1994–95]] season,<ref name=crnvntac>{{cite news |url=https://news.google.com/newspapers?id=QfhPAAAAIBAJ&sjid=ggkEAAAAIBAJ&pg=6827%2C5224406 |work=The Spokesman-Review |agency=Associated Press |title=Coliseum renovation to send Sonics to Tacoma |date=March 17, 1994 |page=C5}}</ref> and it was renamed '''KeyArena''' after [[KeyBank|KeyCorp]] bought the naming rights in 1995. The SuperSonics left KeyArena in [[2007–08 Seattle SuperSonics season|2008]] amid a [[Seattle SuperSonics relocation to Oklahoma City|controversial relocation]] to [[Oklahoma City]]. The arena was also known for hosting minor professional hockey teams, first as home to the [[Seattle Totems]] of the original [[Western Hockey League (1952–1974)|Western Hockey League]] and the [[Central Professional Hockey League|Central Hockey League]] from 1964 to 1975, followed by the [[Seattle Thunderbirds]] of the current [[Western Hockey League]] from 1989 to 2008.

The arena was the first publicly financed one in the area that was fully supported by earned income from the building.<ref>{{cite web|last=Bhatt |first=Sanjay |url=http://seattletimes.com/html/businesstechnology/2014001650_keyarena22m.html |title=Business & Technology &#124; KeyArena's name to change; bank drops sponsorship &#124; Seattle Times Newspaper |publisher=Seattletimes.com |date=January 21, 2011 |access-date=December 18, 2012}}</ref> Arena finances were bolstered for several years by a payment following the settlement with the SuperSonics in 2008, but the lower level of activity and revenue during the time between the departure of the Sonics and the arrival of the Kraken left little reserve beyond basic building maintenance.<ref>{{Cite web |url=http://www.seattle.gov/financedepartment/11adoptedbudget/documents/CENfromARTSCULTUREANDRECREATION.pdf |title=Archived copy |access-date=June 30, 2012 |archive-date=July 28, 2012 |archive-url=https://web.archive.org/web/20120728062954/http://www.seattle.gov/financedepartment/11adoptedbudget/documents/CENfromARTSCULTUREANDRECREATION.pdf |url-status=dead }}</ref> The naming rights deal with KeyCorp concluded at the end of 2010, but the building maintained the KeyArena name until its 2018 closure for the redevelopment.

==History==

===Seattle Center Coliseum===
[[File:Seattle World's Fair Coliseum under construction, 1961.jpg|thumb|left|The structure under construction in 1961]]
The arena opened in 1962 as the '''Washington State Pavilion''' for the [[Century 21 Exposition]], the work of architect [[Paul Thiry (architect)|Paul Thiry]]. After the close of the Exposition, the Pavilion was purchased by the city of Seattle for $2.9 million and underwent an 18-month conversion into the '''Washington State Coliseum''', one of the centerpieces of the new [[Seattle Center]] on the former Exposition grounds. When the newly renovated Coliseum opened, the Seattle University men's basketball team became the arena's first major tenant. In 1964, the facility was renamed the '''Seattle Center Coliseum'''. That same year, the [[Seattle Totems]] moved into the Coliseum.<ref>{{Cite news|last=Baker|first=Geoff|date=2 December 2018|title=More than the Metropolitans: Before NHL arrives, a comprehensive Seattle hockey history|work=[[The Seattle Times]]|url=https://www.seattletimes.com/sports/hockey/more-than-the-metropolitans-ahead-of-nhl-vote-a-comprehensive-seattle-hockey-history/|access-date=11 July 2020}}</ref> The Coliseum became home to its most famous resident, the [[Seattle SuperSonics]], beginning with their inaugural season in 1967 and remaining as host throughout most of the team's lifetime.<ref>{{cite web|url=http://www.buyselltix.com/nba/stadium/supersonicsStadium.php|title=KeyArena – Seattle Supersonics Stadium|publisher=Buyselltix.com|access-date=July 13, 2008|archive-date=July 4, 2008|archive-url=https://web.archive.org/web/20080704135032/http://www.buyselltix.com/nba/stadium/supersonicsStadium.php|url-status=dead}}</ref>

[[File:Seattle Center Coliseum at night, circa 1963 (44058938905).jpg|thumb|left|Seattle Center Coliseum at night, circa 1963]]
The Coliseum in this incarnation hosted two [[NBA Finals]], in [[1978 NBA Finals|1978]] and [[1979 NBA Finals|1979]], both between the [[Washington Bullets]] and SuperSonics. The Bullets won in 1978, prevailing in {{nowrap|game 7}} in Seattle. The Sonics retaliated the following year, winning in Game 5 on the Bullets' home court, thus capturing the franchise's only championship<!-- to date-->. Upon the opening of the new [[Kingdome]] in 1976, which first hosted the [[NFL]]'s [[Seattle Seahawks|Seahawks]] and [[North American Soccer League (1968–84)|NASL]]'s [[Seattle Sounders (NASL)|Sounders]] followed by [[MLB]]'s expansion [[Seattle Mariners|Mariners]] in 1977, the Sonics would begin playing a small number of home games at the stadium. For the championship [[1978-79 NBA season|1978-79 season]], the basketball club moved into the Kingdome full-time. They would call it home through the 1984–85 season, after which the team returned to the Coliseum. During those 7 years, the Sonics would occasionally play home playoff games at the Coliseum or [[Hec Edmundson Pavilion]] so as to not interfere with the Mariners' regular season home schedule. They would continue to play occasional games at the Kingdome through the late 1980s and early 1990s.

The arena hosted the [[NBA All-Star Game]] once, in<!--on January 15,--> [[1974 NBA All-Star Game|1974]]; the [[1987 NBA All-Star Game|1987]] game had included [[NBA All-Star Weekend|NBA All-Star Saturday]] festivities on February 7, where former Sonics star [[Fred Brown (basketball)|"Downtown Freddie" Brown]] was the MVP of the [[NBA All-Star Legends Game|legends game]], [[1986–87 Boston Celtics season|Boston Celtics]] star [[Larry Bird]] won the [[Three-Point Contest|three-point contest]], and [[1986–87 Chicago Bulls season|Chicago Bulls]] star [[Michael Jordan]] won the [[Slam Dunk Contest|slam-dunk competition]].<ref name=nothunus>{{cite news |url=https://news.google.com/newspapers?id=Aa1QAAAAIBAJ&sjid=fOEDAAAAIBAJ&pg=4040%2C1685875 |work=Eugene Register-Guard |title=Nothing unusual in NBA: Bird, Jordan still the best |last=Edes |first=Gordon |date=February 8, 1987 |page=7B}}</ref> The NBA All-Star Game itself for 1987 in Seattle was held at the [[Kingdome]].

The arena hosted the basketball competitions of the [[Goodwill Games]] in [[1990 Goodwill Games|1990]].<ref name=WSdot>{{cite web|url=http://www.wsdot.wa.gov/research/reports/fullreports/232.1.pdf|title=Traffic Impacts During the Goodwill Games|publisher=Washington State Department of Transportation}}</ref>

In 1983, [[Barry Ackerley]], head of the Washington, D.C.–based television, radio, and billboard company [[Ackerley Communications Inc.]], purchased the Sonics from long-time owner [[Sam Schulman]]. In the mid-to-late 1980s, the team's on-court success would decline. This was coupled with a sub-par home court experience at the Coliseum, which included the NBA's lone [[Rainout (sports)|rain delayed]] game on January 5, 1986, when rain water leaked from the roof onto the court as the Sonics played the [[Phoenix Suns]].<ref name=srev>{{cite news |url=https://news.google.com/newspapers?id=AHUzAAAAIBAJ&sjid=T-8DAAAAIBAJ&pg=3637%2C2777131 |work=The Spokesman-Review |title=NBA |date=January 6, 1986 |page=C2}}</ref><ref name=sdc>{{cite news |url=https://news.google.com/newspapers?id=4LESAAAAIBAJ&sjid=t_kDAAAAIBAJ&pg=5101%2C804686|work=Spokane Daily Chronicle |agency=Associated Press |title=Fiddled roof springs leak in Coliseum |date=January 6, 1986 |page=C3}}</ref> Timeouts were called so [[ball boy]]s armed with towels could do their best to wipe up the puddles, but even so, two players slipped and fell on the wet surface.

Ackerley began exploring new options for an arena. Heavy relocation rumors began to circulate, amongst them a potential move to San Diego<ref>{{cite news|last=Granberry |first=Michael |url=https://www.latimes.com/archives/la-xpm-1989-02-03-sp-1821-story.html |title=Sonics' Owner Taking a Look at Sports Arena |newspaper=Los Angeles Times |date=February 3, 1989 |access-date=January 27, 2019}}</ref> or possible sales to groups in other markets like Milwaukee or Toronto. In 2018, Ackerley's son Chris would say that the family was always committed to keeping the team in Seattle, and that "[...] in each case, we stood on our principles that this is a Seattle community asset."<ref>{{cite web|last=Daniels |first=Chris |url=https://www.king5.com/article/news/local/arena/seattles-arena-saga-top-officials-reflect-on-sonics-history-regrets/281-619132800 |title=Seattle's arena saga: Top officials reflect on Sonics history, regrets |publisher=KING5.com |date=November 30, 2018 |access-date=January 27, 2019}}</ref>

====Potential replacement by arena in SoDo====
In 1990, the Ackerleys talked about building an arena east of Lake Washington near [[Bellevue Square]].<ref name="AckerleySuite">{{cite news|last=Newnham |first=Blaine |url=https://archive.seattletimes.com/archive/19900531/1074608/what-about-ackerleys-arena-how-suite-it-is |title=What About Ackerley'S Arena? How Suite It Is! |newspaper=The Seattle Times |date=May 31, 1990 |access-date=January 27, 2019}}</ref> They would eventually purchase land in the [[SoDo, Seattle|SoDo]] district near the Kingdome, some of which includes the site that would later become the Mariners' home, [[T-Mobile Park]]. Ackerley approached the city about a public contribution to the new arena, but the city was reluctant over fears the city-owned Coliseum would become obsolete. They offered to help finance a renovation of the Coliseum, but the team owner declined. To sweeten the offer, Ackerley sold city leaders on the idea that the new arena in SoDo could also attract a National Hockey League club. The city, along with Denver, had been conditionally granted an expansion NHL franchise in 1974 to begin play in the 1976–77 season. The NHL [[1974-75 NHL season#League business|briefly flirted]] with relocating the [[Pittsburgh Penguins]] to Seattle (and the [[California Golden Seals]] to Denver) to address a troubled market and fill the expansion commitment, but ultimately kept the team there. Eventually, the Seattle franchise award was rescinded altogether when the potential ownership group was unable to secure the funds for the expansion fee.

In July 1990, the city council approved a deal for a privately owned $100 million facility to be built on the Ackerley land in SoDo, despite objections over traffic and parking by the Seahawks and Mariners in the neighboring Kingdome.<ref>{{cite web|url=https://www.upi.com/Archives/1990/07/25/City-of-Seattle-approves-contract-for-basketball-arena/8380648878400/ |title=City of Seattle approves contract for basketball arena |publisher=UPI (Archive) |date=July 25, 1990 |access-date=January 27, 2019}}</ref> The city's contribution would be to waive about $31 million in tax revenues (about $1 million per year) to potentially be collected on admissions fees at the new arena. It would also pay $2 million for street improvements around the proposed site, including a pedestrian walkway over South Royal Brougham Way. Ackerley also agreed to sign a 30-year lease for the Sonics and to build an 1,800-stall parking garage. Ackerley appeased the Seahawks' concerns, noting the arena would be empty during any NFL games. The Mariners unsuccessfully continued to object, even enlisting then-Major League Baseball commissioner [[Fay Vincent]] and then-American League president [[Bobby Brown (third baseman)|Bobby Brown]] to speak before the council ahead of their final vote.<ref>{{cite news|last=Nelson |first=Robert T. |url=https://archive.seattletimes.com/archive/19900725/1084120/baseball-official-here-to-fight-ackerley-arena-deal----concessions-to-sonics-owner-concern-citys-other-pro-sports |title=Baseball Official Here To Fight Ackerley Arena Deal - Concessions To Sonics Owner Concern City's Other Pro Sports |newspaper=The Seattle Times |date=July 25, 1990 |access-date=January 27, 2019}}</ref>

During negotiations, Ackerley had asked for a provision to reduce the seating at the Coliseum by 9,000 seats so the older arena could not compete with the new building, but the city would not agree. Another selling point of the new arena were luxury suites, a means to attract corporate money and sponsorship that was then an emerging new revenue stream for sports team owners. Ackerley's financing and agreement with the city hinged on the ability to sell the 70 proposed luxury suites.<ref name="AckDomeDead">{{cite web|last=Lilly |first=Dick |url=https://archive.seattletimes.com/archive/19910626/1291209/new-sonics-arena-dead----financing-troubles-sideline-ackerley |title=New Sonics Arena Dead - Financing Troubles Sideline Ackerley |publisher=NW Hockey Report, SeattleHockey.net |date=June 26, 1991 |access-date=January 27, 2019}}</ref>

Ackerley also committed to submitting an expansion application to the NHL by a September 15, 1990, deadline as part of the arena deal. His son Bill would head the expansion effort, while a competing group led by Microsoft executive Chris Larson and former Seattle Totems player then coach [[Bill MacFarland]] was preparing their own application. With the Ackerley application already submitted, the two groups would merge with Larson and MacFarland being primary points of contact with the NHL. Then owner of the Seattle Thunderbirds, Bill Yuill, also joined the group. Larson and MacFarland, along with Barry Ackerley and Bill Lear, Ackerley's financial advisor, were set to make a presentation to the NHL's Board of Governors on December 5, 1990. At the meeting, Ackerley and Lear asked to meet with the board first, promptly withdrew their application, and left. Larson and MacFarland were stunned to learn of the development but were unable to pursue any recourse as their names were never on the submitted application.<ref>{{cite web |last=Obermeyer |first=Jeff |url=http://www.seattlehockey.net/Seattle_Hockey_Homepage/Seattle_and_the_NHL.html |title=Seattle and the NHL: So Close Yet So Far Away. |publisher=NW Hockey Report, SeattleHockey.net |date=Mar–Apr 2006 |access-date=January 27, 2019 |archive-date=March 3, 2019 |archive-url=https://web.archive.org/web/20190303145414/http://www.seattlehockey.net/Seattle_Hockey_Homepage/Seattle_and_the_NHL.html |url-status=dead }}</ref><ref>{{cite web|last1=Eskenazi |first1=David |last2=Rudman |first2=Steve |url=http://sportspressnw.com/2155236/2013/wayback-machine-seattles-long-wait-for-nhl |title=WAYBACK MACHINE: SEATTLE'S LONG WAIT FOR NHL |publisher=Sportspress NW |date=July 9, 2013 |access-date=January 27, 2019}}</ref>

Thought to play a factor in Ackerley's decision were the significant demands by the NHL for an expansion team: a $50 million expansion fee that was more than any NHL club was valued at the time; a $5 million down payment that would be forfeited if 10,000 season tickets were not sold in the first year – the Sonics had never sold more than 9,000 season tickets; season tickets needed to produce at least $9 million annually, which would've made the tickets the second most expensive for a team in the area at the time; a 20-year lease with a "substantial" share of arena revenues from concessions, parking, and ad signage; priority status for postseason arena dates; and a secured $5 million line of credit in case the league had to take over ownership of the team at any point. Ackerley would not sacrifice Sonics revenues for a hockey team in which he would be a minority investor.<ref>{{cite web|last=Rudman |first=Steve |url=http://sportspressnw.com/2205914/2015/seattle-and-the-nhl-land-mines-on-the-horizon |title=SEATTLE AND THE NHL — LAND MINES ON HORIZON |publisher=Sportspress NW |date=July 11, 2015 |access-date=January 27, 2019}}</ref>

In June 1991, nearly a year after the city agreed to the arena deal, Ackerley announced that the project would not move forward. Increasing project costs, legal disputes, and inability to secure construction financing were cited as reasons to drop the project. Only around 30 of the 70 luxury suites were sold and the Ackerleys were unable to find a corporate buyer for naming rights. Ackerley Communications profits were down, which also contributed to the financing difficulties. A state Supreme Court case brought by Seattle Center employees challenged the constitutionality of the arena deal, while potential lawsuits from the Mariners and trade show organizers and possible legal challenges to environmental review of the project loomed.<ref name="AckDomeDead" />

===Rebirth as KeyArena===
[[File:KeyArena (2890740573).jpg|thumb|200px|KeyArena in 2008]]
Newly elected Seattle mayor [[Norm Rice]] was concerned over a loss of concerts and events to cities with larger, more modern facilities, and the strong possibility the city could lose the Sonics. The mayor believed that sports unite a community and that Seattle Center would continue to serve as a valuable hub for tourism. At his insistence, a Center commission developed a plan to renovate the Coliseum by excavating the floor to lower it and build a new bowl with more seating. The Ackerleys turned down the renovation concept in favor of building their own arena in SoDo. Though the city preferred the renovation, they would reluctantly agree to the new arena plan. After the SoDo proposal fell through, the Ackerleys attempted to find other investors to no avail. Barry Ackerley would return to the city to ask if they would still consider renovating the Coliseum.

[[File:Key Arena.jpg|thumb|200px|Interior of KeyArena when it served as the home of the Seattle SuperSonics (now the Oklahoma City Thunder)]]
With renewed interest on all sides, including the city council, the city spent $250,000 studying if it was even environmentally and engineeringly feasible to dig into the ground beneath the building. The plan proved possible and it was found that the compression ring holding the roof could be preserved, saving $15 million in cost and keeping the facility seismically sound against earthquakes. The original cable-suspended roof would be replaced by a conventional fixed roof with steel trusses that would preserve the well-known shape.

The project had an estimated cost of $73.4 million, considerably less than other new arenas of the time in Portland and Vancouver, to be paid with the city's bond capacity. A new kitchen and support building, a parking garage on 1st Avenue N, a new team store, and a tunnel connecting the store to the arena brought the total cost to nearly $127.3 million. New amenities would include 22 concession stands, 8 portable stands with vending in the seating, three private sports clubs, and a public sports bar and restaurant. [[Club seating|Club-level seating]] with 1,100 seats would also offer exclusive club, concession, and lounge areas, and a private concourse with 58 luxury suites would also be added.

A mandate of the project was that no taxpayer funds could be used to pay for it. This brought concern from the Ackerleys, but after nearly a year of negotiations a revenue sharing plan was developed. The city and the team would split revenues from suites, concessions, and other items all within the arena to service the debt for the city and provide income to the team. The arena would be the first to finance itself by use of the arena. In May 1993, the city council voted 7–2 in favor of the deal with the Sonics signing a 15-year lease agreement and a guaranteed income of $7 million per year during the lease. The agreement was initially turned down in council committee in the hopes of negotiating a 20-year lease with an increased guaranteed income of $9 million per year starting in year 15. The Ackerleys declined these changes.

The Coliseum was rebuilt between 1994 and 1995, bringing the arena up to the NBA standards of the day. The local Seattle office of [[NBBJ]], the second largest architectural firm in the country, was chosen as the architects.<ref>{{cite web|url=http://www.ballpark.org/design.htm |title=PFD: Ballpark Beginnings |access-date=January 27, 2013 |url-status=dead |archive-url=https://web.archive.org/web/20120227031932/http://www.ballpark.org/design.htm |archive-date=February 27, 2012}}</ref><ref name="DJC" /> In an unusual move, the Coliseum would be closed for a year during the renovation. Construction began on June 16, 1994.<ref name="Storm" /> During the [[1994–95 Seattle SuperSonics season|1994–95]] season, the SuperSonics played their home games at the multi-purpose [[Tacoma Dome]] in [[Tacoma, Washington|Tacoma]], about {{convert|30|mi|-1|spell=in}} south.<ref name=crnvntac/>

On April 11, 1995, the city sold the naming rights to [[Cleveland]]-based KeyCorp, the parent of [[KeyBank]], which renamed the Coliseum as KeyArena.<ref name="clerk.ci.seattle.wa.us">{{cite web |url=http://clerk.ci.seattle.wa.us/~scripts/nph-brs.exe?d=CBOR&s1=116474.cbn.&Sect6=HITOFF&l=20&p=1&u=/~public/cbor2.htm&r=1&f=G|title=Seattle Ordinance 122944|quote=AN ORDINANCE relating to the Seattle Center Department; authorizing execution of an agreement with KeyCorp that terminates a prior agreement between the parties and replaces it with a new agreement for the title sponsorship of KeyArena at Seattle Center.|publisher=City of Seattle|access-date=December 18, 2012}}</ref> The renovation cost the city of Seattle $74.5 million and the SuperSonics approximately $21 million. The naming rights cost KeyCorp $15.1 million.

[[File:Keyarena-hockey.jpg|thumb|right|KeyArena's former ice hockey seating configuration]]

The remodeled arena maintained the architectural integrity of the original roofline by using the existing steel trusses in combination with four new main diagonal trusses. The wood, steel and concrete from the demolition was either reused in construction of the new arena or sold to recyclers. The original acoustical panels, the panels attached to the roof that keep the space from echoing, were refurbished and reused. The court was lowered {{convert|35|ft|0}} below street level to allow for 3,000 more seats. The doors opened to the newly renovated arena on October 26, 1995. The sightlines, however, benefitted the SuperSonics at the expense of the junior Thunderbirds. The floor was just barely large enough to fit a regulation ice rink. Many seats in the lower level were so badly obstructed that almost half the lower level was curtained off for T-Birds games. The new scoreboard was significantly off-center in the ice hockey configuration, hanging over one blue line instead of the center-ice faceoff circle.

The first regular season game for the SuperSonics at the rechristened KeyArena was played on November 4, [[1995–96 Seattle SuperSonics season|1995]], against the [[1995–96 Los Angeles Lakers season|Los Angeles Lakers]].<ref>{{cite web|url=http://www.vividseats.com/venues/key-arena-tickets.html|title=KeyArena Tickets – KeyArena Ticket Info & Seating|publisher=Vivid Seats|access-date=December 18, 2012}}</ref> The renovated arena hosted the [[1996 NBA Finals]] in its first season, when the SuperSonics lost to the [[1995–96 Chicago Bulls season|Chicago Bulls]] in six games.

====SuperSonics relocation controversy====

[[File:Last Sonics Game 2008.jpg|thumb|200px|Last Sonics game in 2008]]
In 2001, ownership of the [[Seattle SuperSonics]] (who had called KeyArena home on-and-off since their establishment in 1967) transferred from Barry Ackerley to [[Starbucks]] CEO [[Howard Schultz]]. Schultz claimed that in the five years he owned the SuperSonics, the team suffered heavy financial losses, which led him to seek funding from the [[Washington State Legislature]] for a newer, more modern arena. After failing to reach an agreement with the city of Seattle over a publicly funded $220 million expansion of KeyArena, the Basketball Club of Seattle, led by Schultz, put the SuperSonics and its sister team, the WNBA's [[Seattle Storm]] up for sale. After failing to find a local ownership group to sell the team to, Schultz talked to ownership groups from [[Kansas City, Missouri|Kansas City]], [[St. Louis]], [[Las Vegas]], [[San Jose, California|San Jose]] and [[Anaheim, California|Anaheim]] before agreeing to sell the team on July 18, 2006 <ref name="initialsale">{{cite news|author1=Angela Galloway|author2=Phuong Cat Le|title=Sonics sold to ownership group from Oklahoma City|url=http://www.seattlepi.com/basketball/277945_sonics18ww.html|work=[[Seattle Post-Intelligencer]]|date=July 18, 2006|access-date=July 18, 2006}}</ref><ref name="BasketballClubOfSeattleAnnouncesSale">{{cite news|title=Basketball Club of Seattle Announces Sale of Sonics & Storm|url=http://www.nba.com/sonics/news/sale_060718.html|publisher=Seattle SuperSonics|date=July 18, 2006|access-date=July 19, 2006|url-status=dead|archive-url=https://web.archive.org/web/20060719194751/http://www.nba.com/sonics/news/sale_060718.html|archive-date=July 19, 2006}}</ref> to an ownership group from [[Oklahoma City]], who was pursuing an NBA franchise after [[Effect of Hurricane Katrina on the New Orleans Hornets|hosting]] the [[New Orleans Pelicans|New Orleans Hornets]] franchise successfully for two seasons as the city of [[New Orleans]] rebuilt from [[Hurricane Katrina]].

On February 12, 2007, Bennett proposed using tax money to pay for a new $500 million arena in [[Renton, Washington|Renton]], a [[suburb]] of Seattle.<ref>{{cite news|author1=Jim Brunner|author2=Ralph Thomas|title=Sonics choose Renton|url=http://www.seattletimes.com/politics/sonics-choose-renton/|newspaper=The Seattle Times|date=February 13, 2007|access-date=February 13, 2007}}</ref> After failing to reach a deal by the end of the legislative session, Bennett gave up his attempt in April 2007.<ref>{{cite news|author1=Jim Brunner|author2=Ralph Thomas|title=Sonics owner: "Little hope" team will stay|url=http://www.seattletimes.com/seattle-news/sonics-owner-little-hope-team-will-stay/|newspaper=Seattle Times|date=April 16, 2007|access-date=June 13, 2008}}</ref> On November 2, 2007, the team announced it would move to Oklahoma City as soon as it could get out of its KeyArena lease.<ref name="Post-Intelligencer">{{cite news|last=Johns|first=Greg|title=Bennett says Sonics going to Oklahoma|url=http://www.seattlepi.com/basketball/337871_arena03.html?source=mypi|newspaper=Seattle Post-Intelligencer|date=November 2, 2007|access-date=November 3, 2007}}</ref> Seattle's mayor, [[Greg Nickels]], maintained a stance that the Sonics were expected to stay in Seattle until their lease expired in 2010 and said the city did not intend to make it easy for Bennett to move the team early. Over concerns the city would accept a buyout of the lease, a grassroots group filed a citywide initiative that sought to prevent the city from accepting such an offer from Bennett's group.<ref>{{cite news|last=Brunner|first=Jim|title=Initiative aimed at holding Sonics to KeyArena lease|url=http://seattletimes.nwsource.com/html/localnews/2003808219_keyarena27m.html|newspaper=The Seattle Times|date=July 27, 2007|access-date=February 23, 2008}}</ref> Seattle City Council later unanimously passed an ordinance modeled after the initiative.<ref>{{cite news|last=Brunner|first=Jim|title=Council votes 8-0 to enforce Sonics' lease|url=http://www.seattletimes.com/seattle-news/council-votes-8-0-to-enforce-sonics-lease|newspaper=The Seattle Times|date=September 11, 2007|access-date=February 23, 2008}}</ref> On August 13, 2007, [[Aubrey McClendon]], a minor partner of Bennett's ownership group, said in an interview with ''[[The Journal Record]]'' (an Oklahoma City newspaper) that the team was not purchased to keep it in Seattle but to relocate it to Oklahoma City. Bennett later denied such intentions, saying McClendon "was not speaking on behalf of the ownership group".

On October 31, 2007, Bennett informed [[Commissioner of the NBA|NBA commissioner]] [[David Stern]] that the ownership group intended to move the Sonics to Oklahoma City as soon as it was legally possible. The timing of the announcement, one day after the Sonics' home opener, drew critical comments from Tom Carr, Seattle's attorney, who said "Mr. Bennett's announcement today is a transparent attempt to alienate the Seattle fan base and follow through on his plan to move the team to Oklahoma City ... Making this move now continues the current ownership's insulting behavior toward the Sonics' dedicated fans and the citizens of the city."<ref>{{cite news | url=https://www.espn.com/nba/news/story?id=3091416 | title=Sonics tell NBA of intent to move SuperSonics to Oklahoma City | publisher=ESPN | date=November 3, 2007 | access-date=April 25, 2008}}</ref> Bennett also reiterated that the team was not for sale and dismissed attempts by local groups to repurchase the team.<ref name="Post-Intelligencer"/>

On June 16, 2008, the grassroots organization "Save Our Sonics" organized a well-publicized rally, which reportedly drew over 3,000 participants, at the [[United States District Court for the Western District of Washington|U.S. District Courthouse]] in Seattle to protest the proposed relocation of the team.<ref>{{cite web|last=Raley|first=Dan|url=http://www.seattlepi.com/basketball/367296_rally17.html|title=3,000 rally loud and proud to keep Sonics in Seattle|work=[[Seattle Post-Intelligencer]]|date=16 June 2008|access-date=16 June 2008}}</ref> The rally was held on the first day of the city of Seattle's lawsuit against the PBC to enforce the remaining two years on the KeyArena lease.

On July 2, 2008, two hours before a ruling in the city's lawsuit was to be given, it was announced that the team and the city had reached a settlement where PBC would pay the city $45 million immediately in exchange for breaking the lease, and an additional $30 million if Seattle was not given a replacement team in five years. According to the conditions of the settlement, the Sonics' name and colors could not be used by the team in Oklahoma City, but could be taken by a future team in Seattle, although no promises for a replacement team were given.

Once KeyArena lost the SuperSonics and the Thunderbirds, who moved in 2008 as well, to nearby [[Kent, Washington|Kent]], there was speculation that KeyBank may try to amend the naming rights deal.<ref>{{cite news|url=http://www.seattlepi.com/virgin/371623_virgin22.html|first=Bill|last=Virgin|title=KeyArena lost a tenant; will it lose a name?|newspaper=[[Seattle Post-Intelligencer]]|date=July 22, 2008|access-date=July 22, 2008}}</ref> In March 2009, the city and KeyCorp signed a new deal for a two-year term ending December 31, 2010, at an annual fee of $300,000.<ref name="clerk.ci.seattle.wa.us"/>

In 2009, the [[Seattle Redhawks|Seattle University]] Redhawks men's basketball team began playing their home games at KeyArena for the first time since 1980. In February 2009, the [[Seattle City Council]] approved a new 10-year lease that would keep the [[Women's National Basketball Association|WNBA's]] Storm at KeyArena.<ref>{{cite web|url=http://www.wnba.com/storm/news/lease090202.html|title=STORM: Council Approves Storm Lease|publisher=National Basketball Association|date=February 2, 2009|access-date=December 18, 2012}}</ref>

In 2009, the arena hosted the [[No Way Out (2009)|WWE No Way Out]] [[List of WWE pay-per-view and WWE Network events|pay-per-view]] event. The [[WWE]] returned on March 9, 2010, to tape the March 9 episode of ''[[WWE NXT|NXT]]'' and March 12 episode of ''[[WWE SmackDown|SmackDown]]''. They would return a year later to host the [[Over the Limit (2011)|WWE Over the Limit]] pay-per-view on May 22, 2011. In April 2011, the [[Professional Bull Riders]] brought the [[Built Ford Tough Series]] to KeyArena for the first time.<ref>{{cite web |title=PBR Announces 2011 BFTS Schedule |url=http://www.pbrnow.com/release/?id=6771 |archive-url=https://web.archive.org/web/20100928023610/http://www.pbrnow.com/release/?id=6771 |archive-date=September 28, 2010 |access-date=2022-07-06 |website=www.pbrnow.com}}</ref>

Between June 28 and 30, 2011, the arena hosted the Seattle audition stages in the first season of the [[Fox Broadcasting Company|Fox]] singer search program ''[[The X Factor (U.S. TV series)|The X Factor]]''.

On January 21, 2011, Seattle Center announced that KeyCorp would not renew its agreement for naming rights of KeyArena, after 15 years of sponsorship. However, the venue retained the KeyArena name until its redevelopment, despite the fact that the naming right had expired.<ref>{{cite web|url=http://queenanne.komonews.com/content/name-change-coming-keyarena |title=Name change coming to KeyArena |work=[[KOMO-TV|KOMO]] |date=January 22, 2011 |access-date=December 18, 2012 |url-status=dead |archive-url=https://web.archive.org/web/20120317110206/http://queenanne.komonews.com/content/name-change-coming-keyarena |archive-date=March 17, 2012}}</ref>

In January 2012, [[ESPN|ESPN.com]] reporter [[Scott Burnside]] said KeyArena "would be entirely acceptable", as a temporary venue for an [[National Hockey League|NHL]] franchise, depending on a future arena plan.<ref>{{cite web|url=http://mynorthwest.com/384/619433/Sports-fans-may-be-closer-to-a-new-team-than-they-think|title=NHL Reporter: Seattle a Favorite for Relocated Team|first=Jessamyn|last=McIntyre|work=[[KIRO (AM)|KIRO]]|date=January 30, 2012|access-date=December 18, 2012}}</ref> The [[Phoenix Coyotes]] were often speculated to be a likely candidate for relocation and in June 2013, reports circulated that if the NHL could not negotiate a new lease for the Coyotes with the city of [[Glendale, Arizona]], by July 2, the league would sell the team to a private investment group which would then be given permission to relocate the team to Seattle prior to the 2013–2014 season and use KeyArena as a temporary home.<ref>{{cite web|url=https://sports.yahoo.com/blogs/nhl-puck-daddy/phoenix-coyotes-moving-seattle-roenick-reportedly-part-plan-143114434.html|title=Phoenix Coyotes Moving to Seattle?

Conversely, in February 2012, [[SB Nation]] columnist Travis Hughes said that while it made "too much sense" for the NHL not to put a team in Seattle in the future, KeyArena was completely unsuitable even as a temporary facility due to the same problems with sight lines that ultimately forced the Thunderbirds to move out. Hughes wrote that even one year of NHL hockey in an arena where half the lower bowl sat unused would be "just unacceptable." He argued that the situation would be even worse than what the Coyotes faced at [[America West Arena]], their original home in Phoenix. When the Coyotes played there from 1996 to 2003, they had to deal with seats where part of the ice could not be seen at all, forcing them to curtain off several thousand seats in the upper level.<ref name=SBNation>{{cite web |last=Hughes|first=Travis|url=https://www.sbnation.com/nhl/2012/2/6/2774912/seattle-nhl-relocation-phoenix-coyotes-key-arena|title=NHL Relocation: Why The Phoenix Coyotes Won't Move To Seattle This Summer|work=[[SB Nation]]|date=February 6, 2012|access-date=December 18, 2012}}</ref>

League officials later hinted that a new arena would have to be in place before a new or relocated NHL team came to Seattle. During the 2012 All-Star Weekend, Bettman said that while Seattle was a good fit for the NHL, "there's no building."<ref name=SBNation/> Deputy Commissioner [[Bill Daly]] said that KeyArena would be "a difficult arena for hockey" due to the large number of obstructed-view seats.<ref name=king5>{{cite web |url=http://www.king5.com/sports/Group-interested-in-luring-NHL-to-Seattle-122557174.html |title=Group interested in luring NHL to Seattle |publisher=KING-TV |access-date=June 22, 2011 |archive-url=https://web.archive.org/web/20110528015327/http://www.king5.com/sports/Group-interested-in-luring-NHL-to-Seattle-122557174.html |archive-date=May 28, 2011 |url-status=dead }}</ref>

From 2014 to 2017, American [[video game developer]] [[Valve Corporation|Valve]] hosted [[The International (Dota 2)|The International]], the world championship for ''[[Dota 2]]'' [[eSports]], at the venue, which featured prize pools of over $20 million in 2016 and 2017.<ref>{{cite web|title=The International|url=http://blog.dota2.com/2014/03/the-international-10/|access-date=April 5, 2014}}</ref><ref>{{cite web|title=Tickets to The International|url=http://blog.dota2.com/2015/03/tickets-to-the-international/|access-date=August 6, 2015}}</ref><ref>{{cite web|last1=Porter|first1=Matt|title=The International 2016 Now Has the Largest eSports Prize Pool in History|url=https://www.ign.com/articles/2016/07/27/the-international-2016-now-has-the-largest-esports-prize-pool-in-history|website=IGN|date=July 27, 2016 |access-date=3 August 2016}}</ref> TI returned to the venue in 2023.

===Redevelopment into Climate Pledge Arena, arrival of the Kraken===
[[File:KeyArena 0189 (1).jpg|thumb|left|Arena under renovation in August 2019]]
In October 2016, Seattle Mayor [[Ed Murray (Washington politician)|Ed Murray]] announced that the city would seek proposals to redevelop KeyArena into an NBA and NHL ready venue, issuing a full [[request for proposal]] in January. This came after the rejection of the new arena proposed in [[SoDo, Seattle|SoDo]] by Seattle City Council over the [[street vacation]] of Occidental Avenue.<ref>{{cite news |last=Baker |first=Geoff |date=October 27, 2016 |title=Group headed by Tim Leiweke interested in KeyArena renovation for NBA, NHL |url=http://www.seattletimes.com/sports/nba/group-headed-by-tim-leiweke-interested-in-keyarena-renovation-for-nba-nhl/ |work=The Seattle Times |access-date=April 12, 2017}}</ref>

Two groups, Seattle Partners (led by [[Anschutz Entertainment Group|AEG]] and Hudson Pacific Properties) and the [[Oak View Group]] (led by former AEG CEO [[Tim Leiweke]]), submitted proposals to the city in April 2017 to redevelop the arena, also securing corporate partnerships and seeking the support of the NHL.<ref>{{cite news |last=Baker |first=Geoff |date=April 12, 2017 |title=Prospective KeyArena groups add NHL assurance with new partners |url=http://www.seattletimes.com/sports/hockey/prospective-keyarena-groups-add-nhl-assurance-with-new-partners/ |work=The Seattle Times |access-date=April 12, 2017}}</ref> Both groups were required to submit an additional proposal to preserve the arena's roof, which the city planned to submit for [[List of Seattle landmarks|municipal landmark status]].

On December 4, 2017, the city council approved a [[memorandum of understanding]] with OVG to rebuild the arena by 2020.

In 1977, Seattle voters passed a bond measure to make improvements to Seattle Center.

==Features and amenities==
The post-renovation Climate Pledge Arena is {{convert|740,000|sqft|sqm}} and has 17,100 seats in its ice hockey configuration, with higher capacities for other events. Most of the lower-level seats are subterranean, while the concourse and main south entrance at the Alaska Airlines Atrium are near ground level. The arena has several food vendors that use [[Amazon One]] for contactless payments.<ref>{{cite news |last=Craighead |first=Callie |date=October 20, 2021 |title=A look inside Seattle's new Climate Pledge Arena ahead of Kraken home opener |url=https://www.seattlepi.com/local/seattlenews/article/inside-climate-pledge-arena-before-kraken-debut-16549897.php |work=Seattle Post-Intelligencer |accessdate=October 20, 2021}}</ref>

The arena has a pair of six-sided ceiling [[scoreboard]]s in lieu of the traditional single, center-hung scoreboard used in other indoor arenas. They were designed to not interfere with sightlines and are also positioned higher than other NHL scoreboards.<ref>{{cite news |last=Baker |first=Geoff |date=October 22, 2021 |title=After $1.15 billion renovation, Seattle's Climate Pledge Arena 'will surprise people in the greatest way' |url=https://www.seattletimes.com/sports/kraken/after-1-15-billion-renovation-seattles-climate-pledge-arena-will-surprise-people-in-the-greatest-way/ |work=The Seattle Times |accessdate=November 5, 2021}}</ref>

Concurrent with the announcement that the arena would be named Climate Pledge Arena, it was stated that the venue would aim to receive a [[Zero-energy building|net-zero]] certification by pledging to have all events be "zero-waste" (through use of compostable containers and reduction of [[single-use plastic]]), use [[Rainwater capture|captured rainwater]] for its ice surface, and source at least 75% of food served at the arena from local producers.<ref name=":0" /><ref>{{Cite news |last1=Belson |first1=Ken |last2=Wasson |first2=Lindsey |date=2021-10-29 |title=An Arena Where the Goal Is 'Net Zero' Carbon Emissions, Even From Fans |language=en-US |work=The New York Times |url=https://www.nytimes.com/2021/10/29/sports/climate-pledge-arena-seattle.html |access-date=2022-08-28 |issn=0362-4331}}</ref> All fans holding a ticket to a public event at the arena can claim a free public transit pass for use starting two hours before the doors open and until two hours after the end of the event.
