While we're on the topic of parking I just want to announce that I will be joining the elite few south of DC who live in buildings with underground parking. My new underground garage supports a 27 story and a 35 story condo tower and a 5 floor office building.
Not even a pedestal. Of course when my car lease ends I'm also choosing to go carless (just bought a new Electra hybrid bike and explored some urban jogging/bike paths this weekend with a nice sized group)
I feel so sorry for you guys down there. Your most prime development site may become a garage whose design is literally illegal in every other city unless it's in the middle of some suburban apt complex or way off to the side. I think downtown Jacksonville already offers more parking or about the same as the much larger Midtown Atlanta, with a quarter the office space and 1/12 the residents and 1/3 the hotel rooms.
Many developers I am familiar with are playing the patient waiting game until they can put up their dream mixed-use developments on the most prime spots of land up here (and these are land-locked non-postcard spots unlike the land down there). Dewberry, who everyone in Atlanta strongly dislikes for waiting to do anything, is putting nothing less than 60 stories and heavy hitting retail with underground/concealed parking at 10th/Peachtree. It may be another 5+ years, but in the meantime a Birmingham based urban grocer is occupying a temporary structure on the site to provide some sort of use/activation.
My firm has a piece of land on the fringe of Midtown near the John Marshall School of Law on W. Peachtree, and we've contemplated high-rise apartments/mixed-use and underground parking, but without a market in that particular area for $2.50++/SF rental rates to make it feasible we are putting a park on the site to benefit nearby students and residents. And this is by no means even close to prime real estate.
