One of the most widely planted street trees in temperate cities around the world, legendary for its tolerance of urban conditions, to the point where UFL actually recommends it be planted less often. Less susceptible to anthracnose than P. occidentalis, though still not immune; spores of the fungus can overwinter on fallen leaves if not removed from the site.
Prolific sprouting and good compartmentalizing of decay make it a pollarding candidate, and if the sight (or even mental image) of pollarded trees does not offend your sensibilities beyond recovery then more power to you, I guess.
Robert Kourik, in The Tree and Shrub Finder, writes that it blocks on average 84% of sunlight in leaf (very good) but also 55-57% when bare (not good if shading the house).
Pollen may be allergenic, and leaves may cause contact dermatitis. Salt tolerance is debated (Stoecklein vs. USDA).
'Columbia' and 'Liberty' are resistant to both anthracnose and powdery mildew and somewhat resistant to cankerstain disease, though 'Liberty' is better in the North. 'Bloodgood' is resistant to anthracnose (at least in the north and west), as is 'Morton Naper' (Monumental).
'Yarwood' is resistant to mildew but susceptible to anthracnose and bacterial leaf scorch. 'Pyramidalis' and 'Tremonia' are tree forms that both seed heavily from youth. 'Suttneri' has particularly striking bark.
'Morton Circle' (Exclamation!) has won the PHS Gold Medal Award, having good density and anthracnose resistance.
