Olympic Facilities

I have gathered a few facilities that could play host to events:

UW- BOA Arena - 10,000 seats
UW- Husky Stadium - 72,500 seats
UW- Softball - 1,000 seats
UW- Soccer - 3,000 seats
UW- Pool- 1,000 seats
King County Aquatics Center - 2,500 seats
Key Arena - 17,072
Safeco Field- 47,000
Qwest Field- 60,0oo+ seats
Everett Events Center- 8,250
Kent Event Center- 6,100-7,800 seats
Tacoma Dome- 23,000 seats
Cheney Stadium - 10,000 seats
Everett Memorial Stadium - 5,000 seats?

I was trying to figure out where events could be, and the following facilities would be needed: Tennis, Beach Volleyball, Biking, Cycling, Shooting, Swimming.

A temporary beach volleyball facility could be built on one of the beaches in the area. Push comes to shove, have it at Ocean Shores, WA on a real beach. Tennis could possibly be held in one of the smaller arenas (Kent, Everett, Tacoma). Biking and Cycling would be outdoors obviously so creating paths and trails would be needed for that. Shooting facilities could be a good opportunity for a private investor if the numbers work right. A new swimming facility might be needed as the KCAC doesn't have the necessary amount of seats to host visitors and media.
