I want to throw this question out, because I think fenwick had talked about it previously with a design he had shown earlier in the thread.
Would it not be more reasonable (to minimize costs) to build an expandable stadium? So say start out with similar seating size as Moncton (which if I remember is 10 to 15k? Am I right?) but then have the stadium expandable to an ultimate capacity in the 45k range?
Or; would it be easier to just say to heck with it and build it for a large size 30K and up say? My only concern and the reason I ask is because much like I pointed out earlier; even if half the population (200,000) was in favour of the stadium - the chances that all 200K would go to a game (or want too) wouldn't be at the same level. I'm not a sports fan, but I believe strongly in this project - so now you'd have 199,999 (if I lived in Halifax mind you).
Oh and just for the record, MacMahon Stadium here in Calgary actually doesn't have a huge sea of parking around it. I'm unsure of the actual number of stalls, but if I had to eye ball it from an aerial photo I'd guess in the range of 500 to 1000 cars around the stadium. That creates a MASSIVE parking problem on the adjacent commercial strip malls (across Crowchild and the one on 16 Ave NW and Uxbridge) and in the residential community around it. Part of the reason why the route the NW line took came here, was so that transit could be a more favourable option (that's the reason for the huge ped bridge over Crowchild). The Banff Trail station is only a 5 minute walk - it was also a developing hotel location (Motel Village).
Commonwealth stadium in Edmonton is in a somewhat similiar situation. It appears (from aerial maps) to have slightly more on site and adjacent parking, but it too has an LRT station near by (Stadium station - short walk through a tunnel to a walkway to the stadium). I'm guessing probably 1500 to 2000 cars.
But I should point out that both locations use their parking lots to support transit riders too. So the parking lots (for the most part) have dual purpose for event parking and for transit riders.
