Thanks guys, I appreciate the kind words!
Try not to get too wrapped up in the renderings. They are merely there to provide a bare-bones visualization of the best practices suggested in the article. Totally agree that Hemming needs to maintain some of that old southern park charm, and I'd hope that when it does come time for a redesign, we'd spare no expense in finding an architect that would do the project justice.
Supposedly HDR put together 60% plans for a similar redesign a couple of years ago, but I don't think they were ever made publicly available.
Disagree that the sun would be an issue. If over 60,000 locals are willing to pay $60 a pop to bake in an open concrete bowl in August to watch the Jags get beat by 40 points, I don't see why they'd be averse to hanging out in the park for an hour or two (or a lunch break) in the summer and enjoying free programming or recreation. This isn't Tunisia. October through May are beautiful in Jacksonville, and it's raining half the time during the summer months anyway.
I-10, several of the parks noted in the article are actually smaller than Hemming. Campus Martius Park in Detroit is only 1.2 acres, Post Office Square in Boston is 1.7 acres, etc. Yes, Bryant is dramatically bigger, but don't forget that a) the acreage for Bryant Park also includes the enormous New York Public Library, and b) Bryant is meant to serve a much larger population. Hemming Plaza isn't a miniscule space, and if you really wanted to get creative, there's no reason that you couldn't slightly expand it by removing the perimeter parking or closing the adjacent portions of Monroe and Duval to vehicular traffic.
Not advocating getting rid of trees entirely, but without flexibility, you are severely handicapping Hemming's ability to provide destination programming and activities, and you are also severely handicapping the park's ability to generate the revenue necessary to keep it staffed and programmed.
