Arena Design

Arena Design

OVG is seeking input from the community on the design for the Seattle Center Arena. Their Open House in October 2017 was a chance for community members to join OVG and City representatives to learn about the project and share their ideas. 

Design Commission

The Seattle Design Commission advises the Mayor, City Council, and City departments on the design of capital improvements and other projects and policies that shape Seattle's public realm.

The project team is proposing to redevelop the existing arena located within Seattle Center for existing and future professional sports team, other sporting events, concerts, and shows.  The redevelopment site includes the area surrounding the existing arena as well as the block bounded by 1st Ave N, Thomas St, Warren Ave, and John St. The existing arena, which is a designated landmark, will be expanded below grade to increase overall seating capacity.  The loading area along Thomas St. will be redeveloped into an atrium and pedestrian plaza with parking and loading services located below grade.

On October 5, 2017, the SDC reviewed the pre-concept design for the Seattle Center Arena Development. They did not take an action during that meeting. They provided the project team with several recommendations that should be addressed prior to the next review.

Seattle Design Commission presentation on Seattle Center Arena


KeyArena is more than 50-years old, as are some of the other facilities contained in the Redevelopment Site, and has been designated as a landmark and may qualify for protection. The Landmarks Board, working with the City of Seattle's Department of Neighborhoods, is responsible for administering the Seattle Landmarks Preservation Ordinance, Seattle Municipal Code Chapter 25.12.

The Proposal for renovation of KeyArena will need to take into consideration the possibility of a Controls and Incentives Agreement which will required now that the Landmarks Board designated KeyArena as an historic landmark. The City intends to include the Oak View Group in developing the Controls and Incentives Agreement for KeyArena or any portion of the Redevelopment Site. The Seattle City Council must approve any Controls and Incentives Agreement.

Environmental Impact Statement

An EIS, or Environmental Impact Statement, is prepared under the State Environmental Policy Act. The EIS will evaluate probable adverse environmental impacts resulting from the renovation of the Seattle Center Arena. In September and October 2017, the public was invited to provide input on topics the EIS should study. A draft EIS will be released in the spring of 2018. The EIS will identify impacts and study and recommend mitigation related to construction and operation of the renovated Seattle Center Arena.

Additional Background

The Seattle Department of Construction and Inspections (Seattle DCI) has received a Land Use Application to allow the renovation of Seattle Center Arena. The applicant for this project is the Oak View Group, and the Lead Agency is Seattle DCI.  

The main elements of the proposal include: a 10,000-square foot new entry atrium at grade to the south of and below the existing arena roofline; 225,000-square feet below-grade expansion for additional seating, circulation areas, and new interiors located within existing landmark exteriors; and 65,000 square feet for below-grade loading dock, vehicular tunnel, and accessory services. Parking for 450 vehicles will be provided below-grade. The project will include city permits and approvals for the proposed development as well as a subdivision action.  

Environmental Determination

The Director of Seattle DCI, as the lead agency under the State Environmental Policy Act (SEPA), has determined that the proposal is likely to result in significant, adverse environmental impacts (a Determination of Significance or DS). An environmental impact statement (EIS) is required under RCW 43.21.030(2)(c) and will be prepared. The EIS will evaluate the No Action alternative, as required by SEPA, and two action alternatives.  


Seattle DCI has identified the following areas for discussion in the EIS: traffic and transportation; historic preservation (landmarks and archeological resources); light and glare; noise; land use; and public services and facilities (recreation). Agencies, affected tribes, and members of the public were invited to comment on the content and emphasis (the scope) of the Draft EIS during the comment period. On September 28, 2017, the City held a SEPA meeting to hear comments regarding the Seattle Center Arena. The comment period has ended. All comments are posted to Seattle DCI's Permits and Property Records web page at

SDCI EIS Summary of Scoping Comments


The Oak View Group was asked to identify transportation impacts from the Project and multimodal strategies they would utilize through transportation infrastructure, operations, programmatic and transit service improvements to address and mitigate those impacts. The multimodal transportation strategies should comply with the Seattle Comprehensive Plan and Climate Action goals and focus on accommodating trips to and from the Arena while minimizing single-occupancy (SOV) trips and minimizing impacts to Seattle Center, the Uptown Urban Center, and surrounding neighborhoods.

The City will establish a separate fund or account ("City Transportation Fund") to be managed in the sole discretion of the City, considering input from stakeholders affected by the Development Project, and used to fund transportation improvements in the neighborhoods surrounding Seattle Center.

The City Transportation Fund will fund some of the projects identified in the Mobility Action Plan (see below), including projects that may improve network connectivity for people of all ages and abilities to walk and bike, enhance transit service and connectivity, and improve overall traffic management in the Seattle Center area.

The City will seek other public and private partners and funding for the purposes of advancing the objectives of the City Transportation Fund, including but not limited to King County and the Port of Seattle. OVG commits Forty Million Dollars ($40,000,000) towards this City Transportation Fund. The City Transportation Fund will not be made available to OVG to fund mitigation obligations identified as part of the environmental impact analysis (EIS) that will occur under SEPA.

Mobility Transportation Committee

The Mobility Transportation Committee is a sub-group of the Arena Advisory Committee. 

Mobility Transportation Committee meeting agendas:

Mobility Action Plan

In response to community input thus far on the Seattle Center Arena, the City of Seattle is developing a North Downtown Mobility Action Plan (NDMAP). The plan will build on previous community and transportation planning work, and will identify new actions and prioritize transportation improvements in the neighborhoods of Uptown, Belltown, and South Lake Union. North Downtown Mobility Action Plan efforts are being planned around the timeline for the Seattle Center Arena EIS. The Mobility Action Plan will recommend and prioritize projects to improve mobility throughout North Downtown.
