Thanks for the contribution.

Usually a survey:date isn't needed, but if you want one, I assume you meant 2025, not 2024!

Thanks again, and welcome to OpenStreetMap!

Here's how I got the numbers I did:

According to a 1980 Seattle Landmark Board record on seattle.gov [^1], the towers on the southwest side of the building are 165ft (50.2m). The document also states that the concrete stepson the SW side are 20ft tall. By OSM `height=` rules, those 20ft are included in the height of the tower (165ft from street level, and the SW side is the lowest side of the building [^2]), but I assume the numbers in the document already include those 20ft. Therefore, we can tag the towers as `building:part=tower` and `height=50.2`.

Now the tricky part. The main building (i.e., everything but the towers on the SW side) is *mostly* flat [^3]. However, I can't find any official (or even unofficial) numbers about the height of that main building section. Referencing an official image of the southwest side of the building [^4], however, we can see that the distance between the top of the concrete stairs and the base of the main roof is approximately one-third the distance between top of said stairs and the top of the towers. Because we know the distance from the stairs to the tower-top to be 165-20=145ft (see previous paragraph), we conclude that the base of the main roof is around 48+20=68ft above street level. We add an additional 5 or so feet for the (low-angle) main roof, and get 73ft (22m) height for the main building.

That means we can tag the main building outline with `height=22`, and then to acknowledge the fuzzy estimation we did, we can also add `height:accuracy=estimate` and `height:source=image;extrapolation`.

Thank you for reading. Feedback is always welcome and would be much appreciated here.

[^3]: Key word here is mostly. Notably, the corners on the northwest side of the building are significantly shorter, as the bulk of the cathedral is cruciform, but that can be updated later.

Thanks for the contribution, and welcome to OpenStreetMap!

I see the new buildings aren't in any aerial imagery yet, which makes it difficult to trace them. However, we can still add metadata about them. If you know the addresses of the new buildings, for example, feel free to add new address points in the buildings' approximate locations.

Thanks again!

Thanks for the feedback, I've separated the features.

Welcome to OpenStreetMap! I noticed that you added a non-standard tag "building=car_repair", so I've updated it with another changeset, and added some more metadata. Thanks for your contribution!

Hi! I noticed this changeset also adds a driveway in the Renton area. Con you confirm if this was intentional & if the driveway added is accurate? It looks from aerial imagery like perhaps the driveway continues around the house, but I'm not confident on whether that should be tagged or not. Thanks for your contributions!

Yes, I don't know the park's official boundaries (don't know where to find them either-- can't find the layer on county iMap nor any info on seattle.gov). I just narrowed them from the large rectangle to match the retaining wall around the sides and the boundary of the forest on the back. Not sure what the recommended practice is here.
