The long-awaited Final Environmental Impact Statement (FEIS) for the Seattle Arena has been released and it is a greenlight for us to continue moving forward to finish the remaining work needed for the final construction permits. A summary of that document is provided below for your information.

We want to thank the city staff and technical consultants who worked hard to get this document completed and published. It is a major milestone in our journey to bring the NBA back to Seattle.

We also want to extend our sincere thanks to all of you who have stood by us these past several years. Your support has meant so much to us and made a huge impact on the success of this important project. The EIS is clearly a significant milestone, but there is much more work to be done and we greatly appreciate the continued support from all Seattle sports fans.

FEIS SUMMARY

The final Environmental Impact Statement (FEIS) for the Seattle Arena was published today. This 600 + page document, 2 years in the making, is the product of an exhaustive examination of a number of important issues such as construction impacts, transportation and freight impacts and parking and economic impacts.

While a number of potential transportation impacts, and associated mitigation measures to address those impacts were identified, no significant adverse impacts in any other area were identified.

Transportation

No significant unavoidable adverse impacts to the street system, public transportation, bicyclists, and bicycle corridors are expected. The order of magnitude of change in traffic volumes associated with an arena for any event falls within the range of current event experience. There would be an increase in traffic volumes during peak conditions on event days, which would occur more frequently with the addition of an arena. A number of measures have been identified to reduce the level of traffic volumes, including demand reduction, and management of vehicles to orient them to the most appropriate route.

The EIS studied various scenarios with multiple events at the different stadium venues, up to a maximum attendance of 72,500, such as a typical Seahawks game. With the addition of the Seattle Arena the number of these large event days would increase.

Traffic impacts and travel time effects from an arena only event would generally be the same or slightly less than a Mariners only event.

Adding Arena events to days with Mariners and Century Link events (other than Seahawks) will somewhat increase traffic impacts in the area, but not beyond the maximum 72,500 cumulative attendance already seen at Seahawk games.

The seasonal overlap between NBA/NHL games and baseball and soccer is limited to a relatively small period in the spring and fall. Throughout the winter NBA/NHL season Arena events would not compete against major events in the existing two stadiums. The smaller number of Seahawk games facilitates joint scheduling during the winter.

Various potential mitigation measures were identified to address the transportation impacts, including local intersection improvements, sidewalk improvements for pedestrian traffic, a new pedestrian bridge across the railroad tracks on Holgate and contributions to other mitigation measures identified by the City.

Freight Traffic

The full annual delay costs to Port related traffic from additional Arena traffic is estimated to be $115,584. For non-Port truck trips the estimated delay costs are estimated to be $66,141.
