I'm sure there are a several events held at Legion Field besides UAB football and AHSAA Championship games and I'm not saying move any of those out of the city but who's to say a facility owned by UAB would be open to those event anyway? How often do you hear about events at Bartow Arena that are not UAB events??? How often do you hear about events at UAB's baseball field that isn't UAB's baseball or softball team??? Yeah, they host camps sometimes but they hardly have a large number of events that aren't connected to UAB. Why would a UAB owned and operated stadium be any different?
Are you talking about nightlife around campus at UAB?? Where exactly? Southside is hardly on campus and the only area that UAB would even remotely have a chance to build a stadium would be on the west end of the campus near I-65. There's hardly an argument for nightlife in place in that area unless you count all the liquor stores on Green Springs. The nightlife you speak of will be the Performa Development AT the BJCC (next door to the dome). And IF AND WHEN the trolley's get going, the BJCC and Southside would potentially be connected. I understand on-campus sports venues provide a different atmosphere but you have to also understand that UAB is in the middle of a major metropolitan city. They don't have the land that somewhere like Auburn or Alabama have. They have to fight for the land they get and UAB's best and highest use of the land they get is for research and acedemic buildings. Not for a huge stadium and the infrastructure to support parking of thousands of cars on game day. The amount of acreage it would take to support a stadium on campus with adequate additional parking would consume way more than UAB would be willing to give up. UAB is truly an urban campus and very few truly urban campuses have a large on-campus stadium. Had UAB been along longer and had the foresight to acquire larger swaths of land 50 years ago or 70 years ago, things might be different.
High school band competitions (coming from a former band member) are on Saturday's - the same days UAB plays games. The largest, most well known band competition in the Birmingham area is by far the Hoover Invitational held at Regions Park. It's not going anywhere because the Hoover City Schools benefit from the competition. It will remain in Hoover. The Pinson HS Competition is on campus at Pinson High School; they aren't moving. The whole point of most band competitions is to raise money for the host band - that's why most band competitions are held on campus at the host high school. If they go outside that to a place such as UAB or Legion Field, they have to cover additional expenses associated with the venues. And don't you think the city of Birmingham and UAB would expect some sort of cut from ticket sales and food sales? Another perfect example is Spain Park hosting Sparks in the Park with DCI bands. They do it to raise money for Spain Park's high school band.
Obviously you haven't kept up to date completely on everything revolving around the dome. A lot of the argument against a 60 or 70,000 seat dome is the LACK OF EVENTS that it would bring. There are too many mid-market cities fighting over too few conventions to fill their domes and convention centers. On the flip side of that, there's the argument that a 30 or 40,000 seat dome would be too small to be financially feasible. Having a dome at the BJCC isn't going to bring so many events to town that the existing events at Legion Field can't continue to be scheduled at the new Dome along with UAB home games.
You mentioned several times about soccer games and other small events... You have to also keep in mind the plans for Fair Park and turning that into a sports themed village of sorts. Athletic fields will be included in that project. With a new dome, you also mention the revitalization of the Legion Field area with new homes and retail. Excellent idea... With that revitalization, include a much small athletic complex that seats maybe 7500 to 12000 with a regulation size football field. It could host those smaller events you talk about and also serve as a neighborhood park. They could host rivalry high school games as well. Having this could also help bring a sense of pride to the area having a nice, livable park as well. And just as a side note, if you want to talk about smaller events... there are plenty of city parks around Birmingham that could be revitalized and repurposed to host these smaller events. Crestwood Park provides a great location for Soccer games. Woodlawn High School has a great, historic stadium. There's Fair Park. There's Rickwood Field. The list could go on...
