Clearly, eventual closing has been considered for some time, though I expected them to wait for more suburban sprawl easing the path to rezoning. Since their last new coaster in 2001, they've only put in used coasters and new flat rides that would be quite worth moving. Practically the entire park is reaching expiration date.
I've now seen 2 different videos with Wala Blegay of PG county (see post 110) saying it is not zoned residential and inferring it will not be, they will be looking at something of equal community benefit, but don't know how authoritative that is. I've noticed that very few coasters are operated by local governments, but water parks are definitely a thing. PG county operates several pools and calls one a water park, and across the Potomac, NOVA Parks operates full-blown water parks. Some form of the water park may survive, perhaps handed over to ease rezoning.
Whenever I hear of land being too valuable for a theme park, my thoughts are that part of that value's due to the park, but of course it doesn't have that big an effect. Still, between the local population opportunity cost, a few dollars property loss per home, and business losses surely the combined loss to the area is in the millions, maybe even on the order of what the sale will bring. Even heavily depreciated, people will lose access to over $30M of rides.
Sad. But it's not closed YET. Probably not a good sign for operations this year though.
