The one on High street is not pretty, it was pruned pretty hard and could use some love.
Norway maples are considered weeds in many areas of the county, seems to be typical of the genus, I have tons of japanese maple seedlings coming up (not that I dont like them.) The norway maples are large dense trees 40-50 feet and about as wide. Canopy is very dense allowing very little to grow under them. Seemly hundreds of cultivars with variations in rate of growth, shape and color of foliage. This and most of the other pictures are old ones of low quality from Spokane. You can see a green (its turning yellow in the fall) norway behind the purple one.
Misidentification: Sycamores, look at the leaf arrangement, maples are all opposite, sycamores are alternate, may resemble sugar maple (not really but students often think so) but have not seen one here.
