I don’t really know how much it costs to upkeep a track and associated programs. I also don’t know the current condition of the track or how many useful years are left in it. However, addressing the need for more fields, it’s helpful to understand what’s already there. Looking at Google Maps satellite view, I see the track and throwing/jumping areas within. Immediately next to the track is what looks like a practice soccer field. Immediately next to that is a baseball diamond. 100 yards away from the track in the other direction is a lined soccer field and next to that is a softball field. Certainly, if you want another soccer field, just place it inside the current track and move the jumps/throws somewhere else nearby. Interestingly, I don’t see a football stadium on the campus, though there is one at the neighboring high school along with two baseball/softball fields.
It looks like there’s another soccer field a few hundred more meters away in the adjacent park. At the park, there’s also an off-leash dog park that takes up almost as much room as the track. And another open green area that looks like it has 5 small softball fields (with lines drawn for 3 junior size soccer fields and some other sort of fields).
I have no idea how many soccer and softball/baseball fields they need but I found all this in one small area of the town. That’s more in a large four square block area than I had in my entire town growing up and yet they want to get rid of the track and create more playing fields.
Clearly, it’s hard to monetize the track, as the only way to charge for use would be to have someone working the gate to collect from community members who want to use it. The soccer fields and baseball fields are easier to collect revenue. However, the net cost to maintain them may be greater than maintenance of the track, as I imagine soccer fields get beaten up pretty badly and baseball fields need lines drawn periodically as well as may need maintenance of dugouts, fences, etc if part of the facility.
Anyway, things are not looking great for Track in the US these days.
