There are plenty of open parking lots downtown. Just sayin'.
Lets find somewhere to put it!
Criteria/wishlist:
1. 250,000 - 300,000+ square feet of land (similar to what expo square has)
2. Prefer under government control
3. Prefer existing structure that can be converted to HQ building
4. Prefer somewhere with synergy with existing infrastructure (if we have to build new roads, sewers, etc., $15mil goes away in a second)
5. Synergy with existing businesses (if people stay in a hotel, go to the BMX, and go home the City gains minimal revenue)
6. NOT giving away parkland
A. My first thought are the lots directly north of Cain's. I know TDA owns some land up there, exactly what I'm not sure. But there is plenty of room, it ties in well with the Brady, it is an underutilized part of the City, and a BMX USA HQ sign on the second half of Stove Pipe Hill would be an awesome billboard from 244. It would also utilize existing infrastructure perfectly and not touch parkland.

Most of the same attributes, PLUS the possibility of retaining some indoor facilities but with the added cost of environmental cleanup. However, there is enough land it would be possible to add mountain biking track for cheap, cyclo cross for cheap, or something like a velodrome if we felt overly ambitious (one of the things you show on a possibility plan, but likely never actually build).

Directly across the BA onramp from Boston Ave. Methodist church there is a large section of unused land that the freeway wraps around. Use it. There is plenty of surface parking for events, so long as it isn't a church day in the middle of a TCC school day. While it doesn't tie in very well to a district, it is close PLUS the BA is a direct line to the fair grounds (where the BMX nationals take place around Thanksgiving).

Much of it is City controlled, unfortunately some of it used for drying out solid waste... but there is a lot of land over there. Hard to use land. It would tie in well with the trail system, the desire to develop the river, and the bike improvements coming to Turkey Mountain.

Some of it is City, much of it I believe is held a well known Tulsa family. It used to be part of the trail network at Turkey, but was cutoff. Close to existing infrastructure at Tulsa Hills and ties in great with the trails. Easy trip from several ways to get to Expo. Also - it could be built to seem as if it were in the woods (and largely it would be). Bonus - open the rest of the land up to expand the Turkey Mountain trails.
