Good grief libertarians....Planning does not equal regulation...at all. Zoning does sure, but there is a lot more to the economic development/redevelopment/long range planning aspect of planning than just zoning. I'm an economic development/redevelopment planner and if I was DIA director there are some things I would deregulate. As to the whole liberterian notion of just let whatever be will be and let the free market do its thing. Sure, the public sector should try to facilitate the ease of business for the private sector...but we are also talking about how millions and millions of public dollars will be spent downtown. Without a proper long range vision of how to spend that money in the interest of the public and economy, we're just blowing money and wasting opportunities.
Downtown has always had leadership problems and structural problems, not a problem with "too much planning". In fact, I think most reasonable people would agree that its had a too little planning problem or poor quality planning problems. A quality planner, economic developer, or real estate guru should be able to make Downtown substanially better than it is. With help from involved citizens, organizations, and the private sector of course.
