A very brief search led me to some sports complex plans in my area in the past couple of years.
One opened in FishHawk Ranch (newer development) at a cost of just under $10 million for 70 acres. No pool, mostly fields, concessions, restrooms.
One proposal was for a very controversial $40 million project on over 400 acres, with a midsized stadium surrounded by other playing fields. As far as I know it is dead in the water.
It seems like the county is looking at a multi-use building for arts and sports, some fields, and hopefully a pool? I would be all for it but paying for it is another issue. As someone who communicates directly with renters on a frequent basis, I don't think expecting them to cough up additional dollars to pay for it is a good plan at this point. Maybe revenues will be up without raising the taxes by the time the plans are ready to go.
