Above here is a photo of the Stadium area in Seattle. To the left you see Qwest Field and Safeco Field, and on the right you see a red box, which is the location I have chosen here. Driving by this area it looks like a Metro Bus barn, but not certain. A bus barn is a very easy thing to relocate. Yes it is at a perfect spot for freeway access, but that is also prime real-estate. There are also many other locations it could be moved to nearby.
This location would be ideal for a new multi-purpose arena for many reasons. Prime factors would include easy freeway access. You don't need to build any new infrastructural needs to accommodate. You are taking advantage of this luxury. Another is parking. You already have the Qwest Field Parking Garage, as well as the Safeco Field garage. And of course, many places nearby to find a parking spot. The 3rd is a newer option- the Stadium Light Rail station is right next to it. If you live on the south end, you can take the light rail train from Tukwila straight to the game, not pay a penny for parking, and take the train home afterward. Weekdays 2 Sounder trains will leave Tacoma, arriving in Seattle at 5:30pm and 6:00pm.
Development around the new arena would almost be a guarantee. As mentioned in the blog post below, there are many reasons to build the arena. How about creating a large Entertainment Center? Dallas has one called the AT&T Plaza shown here http://www.americanairlinescenter.com/about-aacenter/center_venues.php Can you imagine parking at one of the stadium parking garages or getting off the train and walking thru the Plaza on the way to the game? You can go through numerous restaurants, bowling alleys, ice skating rinks, theaters, etc. It could be a real Seattle destination spot. It could be used year round, with people using during football and baseball season in addition to events at the arena.
