I don't think we need to have a garage within a block of everything, and didn't imply that. The point I attempted to make is that replacing our many surface lots with a couple garages would help free up land for real development. Would I rather have more transit than more parking? Absolutely. But first, we need to get rid of the surface lots we have and actually use the land we've decimated. And we have to build up a residential, commercial, entertainment and office density downtown in the meantime.
Trust me I agree. Did you see the last map I posted of the walking distance from the 3 garages around 4th and Cincinnati, the Williams Garage, and the City Hall Garage (if they were to open it to public). The Blue Dome has MORE than enough parking to support the infill of a lot of those surface lots with out having to build another structured parking facility. The capacity is there, it'll just require people to walk 1000 feet instead of 300.
The same thing can be said about the Brady. The Williams garage will serve just fine for the area, and if the garage gets built for the Pop Museum even better, then add the City parking garage which is accessible in a short walking distance to the Brady as well. I think we are several years off in development from needing any more public parking spaces needing to be built.
