UPDATED (8/4/2025): The city council updated Select Committee on Civic Arenas meeting times to discuss KeyArena redevelopment. Changes highlighted below.
After considering competing bids for a KeyArena renovation over the spring, the city of Seattle now has two proposals before it for a new state-of-the-art arena to support professional sports, concerts, and cultural events. One in the city’s Stadium District south of downtown and Pioneer Square; one at Seattle Center in the city’s Uptown neighborhood.
The anticipation is to decide on a single project this fall and move forward on a clear course of action for the future. So, what's next in the process?
The two options:
Seattle Arena
Location: 1st Ave S/S Massachusetts St/S Holgate St, SoDo
Estimated Cost*: $550 million
Estimated Size: 700,000 sq ft.
Seating Capacity: 18,500 (basketball), 17,500 (hockey), 19,000 (concerts), can expand up to 2,000 additional
Additional Feature: On-site training facility
Investor Chris Hansen's group - including former Sonics player and executive Wally Walker, retail empire magnates Erik and Pete Nordstrom, and Seattle Seahawks starting quarterback Russell Wilson - offered in October 2016 to fully finance the project privately in exchange for an exemption on admission taxes and a reduction of the business & occupation taxes charged on revenue made outside of Seattle.
The group seeks a two-block vacation of S Occidental Avenue that bisects the arena site. Their public benefits package for the vacation, given approval recommendation by the Seattle Design Commission in April, includes a public plaza, living machine water reclamation system, pedestrian/bike bridge over train tracks, a parking garage with potentially larger capacity than the Mariners' garage, financial contribution to freight mobility improvements, and an earmark for the money paid for Occidental Ave to go to the Lander Street overpass project.
New Arena at Seattle Center
Location: 305 Harrison Street, Lower Queen Anne/Uptown
Estimated Cost*: $564 million (possible ~$600 million with underground parking)
Estimated Size: 660,000 sq ft.
Seating Capacity: 18,350 (basketball), 17,100 (hockey), 19,100 (concerts)
Arena management and consultancy Oak View Group - created and headed by former NBA executive, former NHL executive, and former president of AEG Tim Leiweke, and music industry artist mogul Irving Azoff - has proposed a renovation of the existing KeyArena that would dig down 15 feet to expand the footprint of the arena and more than double the existing square footage. Anticipating landmark status, the project would retain the building's distinctive roof and the outer walls above ground. A new atrium would be added to the south end for entrance. A ramp going beneath Thomas Street will open to an expanded marshaling area with 8 loading docks.
An 850-spot parking garage concept adjoining the atrium was dropped following neighborhood feedback and concern over financial participation of a public entity, expected to be the Port of Seattle.
The group proposes a 35-year lease with the city for the land with five (5) 10-year extensions possible. The project would be built privately and OVG offers a $1 million annual lease rate with the potential to increase rent payments if annual revenue thresholds are hit. The potential to negotiate tax revenues to feed back into the operation and maintenance of the arena has been left open.
*Estimated cost is just for arena project. Environmental & traffic mitigation and public benefit cost not included.
What's next for SoDo
The SoDo proposal is in the hands of the Seattle Department of Transportation. After analyzing the project, they will draft a report and make a recommendation to the city council's Select Committee on Civic Arenas on whether to grant the proposed street vacation or not. As they have gone through this process with the arena before, it's likely most of their analysis can be reused.
SDOT does now have to take into consideration plans for S Occidental Avenue to be dead-ended at Lander Street for the overpass project. There is no deadline or timeline on when their analysis and recommendation will be done.
What's next for KeyArena
A 3-member executive review team, advised by a 10-member community panel, submitted its recommendation of the OVG proposal to Seattle mayor Ed Murray in the first week of June.
The proposal was selected by Murray over a competing proposal from Seattle Partners, a joint venture between arena developer AEG and real estate firm Hudson Pacific Properties. Seattle Partners withdrew their proposal prior to the expected selection, citing the lack of “a sufficiently thorough, objective and transparent process” on the city’s part. SP’s ask for up to $250 million in bond-backed public financing and its design proposal to cut 15% of the building’s roof to expand to the south are said to have taken them out of the running early on.
The city council recently announced it will hire an independent consultant to review the OVG proposal to aid in negotiations of a Memorandum of Understanding and a development and lease agreement.
Historic Landmark Status
The city has submitted applications to nominate KeyArena and six other buildings on the identified renovation project site for historical landmark status per State Environmental Protection Agency policy and city statutes. OVG plans to submit the building for federal historic preservation tax credits to offset development costs.
The Seattle Landmarks Preservation Board recently reviewed and approved a majority of the nominations, including KeyArena. They will review the nominations to see if they meet specific criteria for landmark designation. If the Board designates the arena and/or any of the buildings as landmarks, they will negotiate a Controls & Incentives Agreement with the city/Seattle Center. Per the city:
Controls define those features of the landmark to be preserved and outline the Certificate of Approval process for changes to those features. Incentives may include, but are not limited to, zoning variances, building code exceptions, and financial incentives.
After the agreement has been reached, the Board will forward ordinance legislation to the city council for the designation(s). The council will vote to approve or deny the ordinance.
Updates
7/8/2017: The city released a timeline of the KeyArena renovation proposal review. Added dates highlighted below.
A Timeline of What's Next
Here is a timeline of the next steps in the process. Some of this is in flux as analysis of the two projects could change when events take place.

Comments
Can Hansen apply again
if this street vacation is denied??, looks like Key Arena is going to happen, let it. The NBA is several years away from expanding, I think Hansen should apply for his street vacation then, why now, bad political climate for him. If in several years the NHL is here or been here, the traffic nightmares will be seen by all, the NBA expands, thats when Hansen should apply for the street vacation, have a no compete with Key and we have two arenas, So Hansen should wait it for 5 years, 7 years. Just make sure in these Key arena negotiations they don’t impose a one arena only clause etc.

Timeline is awesome to have! Thanks!
I’ll have to save this as a reminder of upcoming deadlines.

I am surprised that #'s wise the seattle center building doesn't appear THAT much smaller
than SODO. I understand the ancillary facility and surrounding revenue sharing/retail/parking/transportation infrastructure iare all far superior in SODO. Just looking at the size of the building. the sq footage has been a big issue. I’m asking honestly, as far as arenas are concerned, is the difference between 660k sq feet and 700k an influential difference? To someone who knows nothing about architecture it doesn’t sound like a giant difference.
By 206er on 07.03.17 10:45am
The size isn't that much different...
But there is a still a substantial variance there. Plus the footprint/space is already there for Sodo and for the practice facility as well. For the Key Arena I can almost guarantee this will be the absolute last renovation for this buildings history. Where as in Sodo there can be another remodel due to the footprint already in place. Kind of like in Utah where the Jazz already have the footprint to renovate unlike the Key back 20 years even until now.
Plus with the Sonics rings the attendance can reach up to over 20K. For an nba owner that is huge, plus it won’t be split 3 ways like it would be at the Key Arena remodel.
By WoodLandSonic40316 on 07.03.17 1:16pm
It shows how numbers can lie...
One building is going to be a more spread out and comfortable 700,000sq ft and the other will be the equivalent to digging a really deep narrow hole. If (as we expect) the Key Arena ends up being the choice, I think people who have had the pleasure of attending a game at one of the newer arenas around the country will find the KA experience very strange and confining.
By blykmyk44 on 07.05.17 10:46am
It's the footprint
SODO can grow for future needs. Key Arena can not and does not have room for ancillary development.
By DJDawg77 on 07.03.17 8:08pm
This makes sense. key has NO opportunity for growth
Thanks. I was just taken aback that OVG’s facility renovation’s numbers compared to SODO. Seemed closer than I had thought. I understand that there are ancillary components and opportunities for growth, etc.
By 206er on 07.03.17 9:58pm
SODO
Will have all the goodies for an NBA team like a practice facility. Not a deal breaker at Key amArena but just another annoyance for an NBA owner
By DJDawg77 on 07.04.17 9:41am
We still don't know how much tax money Murray is gifting OVG
Then somehow the could is supposed to turn that around an have a public meeting.
That’s a recipe for delay.
They needed to set and stick to the RFP. Instead, Murray is fishing with tax dollars.
We will know the mayoral candidates before then, they will weigh in on the give away, too.
The timing isn’t great for this, and Murray is not selling any candidate’s future, but his own legacy.
By Mike Baker on 07.03.17 11:15am
Good points
It’s really frustrating that Murray is more intent on cultivating his legacy at the expense of taxpayers than finding the best deal at a good price. I’m curious to see if they mayoral candidates (except for McGinn), when asked, will be this intent on creating their own legacy rather than actually fixing the problem.
By 206er on 07.03.17 11:43am
As a city asset. .. . .Seattle Center is a responsibility of the City and taxpayers. Any Mayor needs to act accordingly and responsibly.
And that’s as it should be. My frustration with Murray and the current SCC is they don’t seem to want to explore any alternatives for a re-purposed Key. This region has grown so much. . . .it’s time to look to look forward rather than backwards. Sodo is the right location for an arena in the Stadium District for all the obvious reasons. Finding a financially viable plan for Seattle Center and re-purposing the Key is the responsible thing to do. At least from my viewpoint.
By kinsesu on 07.03.17 11:58am
$100m in tax money is a tough sell.
By Mike Baker on 07.03.17 2:52pm
Are you certain that no developer would he willing to renovate Key Arena on a smaller scale?
The key (pun intended) word in Kinsesu’s response is "explore".
By itsanospreybich on 07.03.17 3:01pm
Im surprised the council didnt ugre in the RFP a councert only venue be explored as well and accept designs for that and costs involved
Knowing that there is a free arena (yes I know Hansen wants what the M’s/Hawks get) would make me wonder about a concert only cost and see if that would have stuck with the original no city financial commitment especially considering the landmark status kickback the developer would have been able to use. I know if I was a councilor I would have wanted to see both of those options even if someone else had only submitted concert only.
By Trolltossin on 07.03.17 4:14pm
$100 million for what ?
If the City can’t find a way to keep SCenter and Key financially viable and relevant in this new and continued growing Seattle — – they need to sell the property. They’d make a boatload of money. Perhaps naming rights could help.
You know . . .just like the stadiums do. Amazon’s SeattleCenter. MSFT Windows Seattle Center.
Continuing to try and fit a square peg in a round hole that could end up a financial boondoggle and horrendous traffic nightmare for years to come seems very egotistical, short-sighted and living in the past. At the very least. . .. . they should be willing to explore alternatives.
Seattle Center costs money to keep maintained. If the city wants to keep it as an asset. . . .. they need to figure out what it’s future purpose is and how to pay for it. A state of the art arena that hosts concerts, the NHL & NBA with projected enormous negative transportation impacts for this area ? Is that really the only solution ? Is it even the right solution ?
By kinsesu on 07.03.17 4:34pm
It's ultimately not the right solution
but as far as the city is concerned, it’s the politically easiest path for the Mayor and the council to take, and as far as transportation chaos in LQA/Mercer, let them eat exhaust. And Eddie gets to punch McGinn and establish a solution on his terms.
By NWEastcoaster on 07.03.17 5:45pm
I keep hearing they need a new high school for downtown students
The Seattle Center sounds like a good place to build it.

By Trolltossin on 07.03.17 11:45pm
All they have bothered to look for is Murray's arena solution.
Take all that up with the guy they did one RFP one one option and is not throwing tax money at his personal preference.
By Mike Baker on 07.03.17 6:35pm
One alternative for a re-purposed Key
I would like to see Seattle have is a world class Aquarium.
By unknownn on 07.03.17 5:55pm
This candidate is pretty plain with his feelings
By Mr. Shea on 07.03.17 1:02pm
But is he actually for sodo arena though?
By gstommylee on 07.03.17 1:59pm
What other arena is there? Tukwilla??
