Ackerley began exploring new options for an arena.

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."

. 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 briefly flirted with relocating the

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 Eventually, the Seattle franchise award was rescinded altogether when the potential ownership group was unable to secure the funds for the expansion fee.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. 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

to speak before the council ahead of their final vote. 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. 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

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. 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. 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.

Rebirth as KeyArena

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. Key Arena

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-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. KeyArena pano

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 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,

. In 2006, 74% of voters in Seattle voted to pass Initiative 91, a measure that prohibited use of tax dollars on arena projects in the city unless it could be shown the city would turn a profit on their investment. The limitation of tax dollars that could be spent on the arena, combined with earlier losses under recent ownership groups, "likely doomed the Sonics' future in the city". On February 12, 2007, Bennett proposed using tax money to pay for a new $500 million arena in Renton, a

of Seattle. After failing to reach a deal by the end of the legislative session, Bennett gave up his attempt in April 2007. On November 2, 2007, the team announced it would move to Oklahoma City as soon as it could get out of its KeyArena lease. 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. Seattle City Council later unanimously passed an ordinance modeled after the initiative. On August 13, 2007, Aubrey McClendon, a minor partner of Bennett's ownership group, said in an interview with ''

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." Bennett also reiterated that the team was not for sale and dismissed attempts by local groups to repurchase the team.

On June 16, 2008, the grassroots organization "Save Our Sonics" organized a well-publicized rally, which reportedly drew over 3,000 participants, at the U.S. District Courthouse in Seattle to protest the proposed relocation of the team. 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.

matches. Minor expansion occurred as the SuperSonics grew in popularity, but the design of the arena limited its expansion potential; calls for its renovation occurred as early as 1976. In 1977, Seattle voters passed a bond measure to make improvements to Seattle Center. Permanent ticketing areas were added to the arena eliminating the portable ticket booths that were in use since The Seattle World's Fair. In 1983, the original seats were replaced while improvements were made to the concourses to compete for concerts after the Tacoma Dome opened. With the 1995 renovation, the arena's capacity was expanded to 17,072 for basketball, 15,177 for ice hockey and ice shows, 16,641 for end-stage concerts, and 17,459 for center-stage concerts and boxing. Risers held 7,440 on the upper level and up to 7,741 on the lower level, with luxury suites adding another 1,160 seats. However, the ice hockey capacity was reduced to 10,442 when obstructed seats were removed. The redeveloped arena features a new interior and entrance atrium while retaining the existing roof and three exterior walls. It seats 18,300 for basketball, 17,151 for ice hockey (as well as arena football, box lacrosse, indoor soccer, and ice shows), and 17,200 for concerts.

Concurrent with the announcement that the arena would be named Climate Pledge Arena, it was stated that the venue would aim to receive a net-zero certification by pledging to have all events be "zero-waste" (through use of compostable containers and reduction of single-use plastic), use captured rainwater for its ice surface, and source at least 75% of food served at the arena from local producers. 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. In the first year that the passes were available to Kraken and Storm ticketholders, 25% of fans used public transit.
