- Yes, agree with the degrees referencing the compass heading to air navigation obstacle (Madrid) from JGG.
- Good find on the FAA extension. Had in my head it was needed by EO March, not Feb.
- As for the reason for the waiver... I stand by them actually needing it. Maybe it's south of 300' tall (perhaps approaching 300' down to the Rhine), but a few have had top hat figures in the high one hundreds.... I just don't believe they'd be that far off or overshoot that much for a margin. I also believe it is for the top hat, not the spike. Also, all of the documentation has consistently placed the high point more-or-less near the top hat. Technically speaking, everything aligns "better" with element #16, Inverted air time hill...but I think that's just some small error in the balloon & FAA placement, and it's not that far off from the top hat. The spike is much further away. I think the #14 Outward-banked airtime hill will be the third-tallest element, behind the spike and the top hat.

Still doesn't necessarily prove the ride is going to be 300 feet though. It's cheaper to renew an old height waiver than file for a new one, and provided you do not exceed the height waiver's permitted height you can build at any point below that.
The confusing part is the specific height waiver location (pictured below) is not in line with either the top hat or the spike, is closer to the spike, and is 83 feet above MSL not 72 feet as per the permit papers. The top circle is the spike, the middle circle is the permit height location, and the bottom circle is around where the top hat will be.
According to the FAA website, there is no cost in filing a height waiver.
I tend to believe it's the spike. As @thopping suggested, perhaps an error in the exact placement. As @b.mac , I ran the FAA waiver location on 3 maps and it comes up on the green pasture line near the barn (very close to his yellow dot). That's pretty far off from the top hat.
For those more technical than I - The FAA filing states "Survey accuracy 4D". This is what the FAA says regarding 4D - These accuracy standards typically require a 4D adjustment of 250 feet horizontally and 50 feet vertically to be applied in the most critical direction. Normally, these adjustments are applied to those structures that may become the controlling obstructions and are applicable until their elevation is verified by survey.
So, the location and height on the application is not exact (if I read that right). I'm assuming the "most critical direction" would be the airport which is almost 95° west. Interpreting here - If the center location is where @b.mac and I deduce, it could be up to 250ft "up"(spike) or "down" (top hat). In a Google maps measure feature, the spike is about 115ft while the top hat is about 269ft from center point. Further, it could be as tall as 365 ft or as low as 265ft. I'm guessing the latter.

As I've read, all FAA waivers for this type of construction are all 4D (with the variances I wrote). So this is as accurate as it'll get until it's completed for an exact survey. They just extended the existing before it expired. Nice job by @chrisorris24 in finding it.
The funny part is I found it by Googling the Latitude and Longitude. The first two links are the FAA documents, and those documents have clickable links. For what it's worth there is a little bit mentioned in there about how the 315 ft height is not to be exceeded by Cranes, and Rigs associated with construction.

So fun urban planning story time:
Changing heights at the last minute is not all that uncommon, and possibly one of the most famous one is the Chrysler Building in Manhattan. The Empire State Building and Chrysler Building were being built at the same time (finished 11 months apart). They were in a race to be the tallest building in NYC (and the world at the time). Both were being very vague about their height at the time.
As the Chrysler Building was nearing completion, as an effort to conceal the actual height, they built the spire within the Art Deco roof, and on the day before the building was to officially open, they pushed the spire up through the roof, going from 925 feet tall, to 1,046 feet tall.
Of course all of this ended up being little more than showsmanship, as the Empire State Building was still under construction, the planner simply added another 5 floors, then the 200 foot spire (that’s now very iconic), and finally a 222 foot “mooring post”.
Interestingly it was during this time of skyscrapers and “The race for the sky” that the idea of “height restrictions” started to come into play, as planners needed better control over what was happening, mostly so no last minute unsafe changes could happen to a building.

That’s a great story. I learned of that a few years ago. But just for a wee correction, it was in competition with 40 Wall St. tower which is The Trump Building on Wall St., not the Empire St. Building.
It was all 3, but 40 Wall St wrapped up long before the other two pushing competition between Chrysler/Empire ?
This is what I've been saying. I think the 315ft is for cranes. I do think this will be a hyper.
It doesn't belong here...but I assume those eye hooks are to hang your Collector Pin Lanyard....

Can't wait for a guest to slice their finger open on one of those. Speaking from experience here.
We saw plans that just showed the generic car intamin car from behind and unthemed top view. Which Zachary said was a just a placeholder.
