If a ballpark ever happened, I think we’d need to get creative with designing it…bear with me here.
Ingress/egress: my preference would be an urban, hub/spokes model. Like I said before, if it were to come, it would likely be secondary to transit. Have people park offsite (from Durham, Cary, wherever), and shuttle in via BRT or light rail. I’d even love to see some kind of bike-share or massive bike rack corral to encourage people biking in! Can you imagine being able to take the greenway over to a ballgame? And if you make it urban, you increase walk-up traffic from those who live in DTR, and you encourage retail/restaurant/bar growth around it.
Functionality: Make it multi-purpose and functional year-round: Incorporate offices into it, incorporate housing into it, maybe blend it into Dix Park (I’m thinking Central Prison site now!), maybe replace Red Hat Amphitheater as the new outdoor venue for concerts (assuming RHA is ever developed into something else, which is kinda the plan).
I just think we need to reimagine what a ballpark is and how it’s designed. It doesn’t have to be this massive boondoggle that fits the description of every other park and gnarls traffic and only gets used for a few months of the year…
