Davis is primarily a college town. Is there enough demand to fill up a skyscraper?
Of course, any new construction won't be priced toward that crowd. But yes the demand could feasibly exist.
Taller buildings cost somewhat more per square foot. You need a stronger foundation and building materials, past a certain height you need pumps for water and things like that.
That's worth the cost where land is expensive and you're building a 30 story building next to a bunch of 15 story buildings you'd otherwise have to knock down. When you're building next to cows, you just build five story buildings or two story buildings and build more of them, because the land isn't that expensive.
This is presumably why it's easier to pass there. Not going to be a lot of takers on the skyscrapers.
Though it could still be useful if you get some five story buildings where there might have only been single family homes.
Also the same rules currently apply in Redondo Beach which is a little bit more expensive.
My school has a third the enrollment of davis and has two 12 story residential towers plus a smaller one (or something, they've been doing a lot of construction), so assuming everything is like for like (which is a terible assumption), you could have similar housing for Davis with a 72 story tower. That's definitely a skyscraper, although not in competition for any height prizes.
Usually something that big will be in a dense urban core though. My impression is that Davis doesn't have the density where it makes economic sense to build that high. Probably would be easier and cheaper to do something around 10 stories, maybe with a large footprint.
