All or part of the expense of grading, paving, or graveling any street may also be defrayed by a special assessment upon the lots and premises abutting upon the improvement, in proportion to their number of feet front upon the street. The lots and premises to be assessed according to their frontage upon a street improvement constitute a special assessment district. As used in this section, "paving" includes curbing and the construction of crosswalks in the paved streets.
