There's an official list of permissible trees, quite a long

I remember being dissapointed Perotia was not permitted.

Parrotia persica is on the approved list of Seattle Street Trees - an ideal choice
for a parking/hell strip. Slow growing to a very manageable size, no mess, no
fuss, drought and pollution tolerant and drop-dead gorgeous fall color. Don't
understand why they are not more common.
