I was over at Transition Rogers Park when I read post about this. I read through all the comments too. I also found the brochure over at FOTP. This is the caption for the Pratt Beach location:
Submerged breakwaters or reefs create new aquatic habitat while protecting the beach sand from being carried away by winter storms.
This doesn't read like a plan for a marina to me. I am not sure the space is large enough to accommodate one. However, it's possible I am being snowed by the brochure since I haven't been party to any discussions as to what is really being planned.
All the same, I do have some observations around the comments and definite ideas of my own.
First of all, I agree with North Coast. Boating is an expensive hobby. If a house is a "money pit" a boat is a "money pit on steroids". I have seen news reports and pictures of abandoned boats and repossessed boats. Unless a boat is your primary residence (and it is for some folks) it's not a necessity. Westgard is also correct about choosing the priorities to spend our capital on. It is a given that our future is going to be different than what any of us expect. Would we rather build marinas for toys or work on rebuilding the infrastructure to keep the city working in that future, such as sewers, waterworks, the electric grid, and public transportation hubs?
I personally would love to have a bike path (yes and walking too) along the lakefront that runs from Evanston to Indiana, even if I am not ready to bike that far just yet. If the plans for the lakefront are limited to uniting the existing park space and creating a contiguous park from Evanston to Indiana then I am all for it. Anything beyond that, aside from pedestrian access in the southern end, is overkill IMHO.
