Pollen is not a side effect. Bees forage for three primary things: nectar, pollen and sap. They make honey from the nectar and "bee bread" from the pollen. Pollen is their only source of protein. Without it they would die. They use sap to make propolis to seal up the hive and glue things in place.
There is indeed plenty in an urban environment. Heck suburban bees live in bee paradise. Year round forage, diverse sources, all that irrigation to keep things in bloom...
