Where water or sewer lines are constructed across or through lots or tracts of land or when water or sewer lines, or both, are installed along both sides of corner lots and were or are financed in whole or in part by assessment, the Council may by uniform rule classify such lines for assessment as in its judgment will represent the benefits derived. The schedules of exemptions may be classified as to land uses (residential, business, commercial, industrial, office and institutional, agricultural, or other classifications) and shall be uniform for each such classification used; provided, however, that no schedule of exemptions may provide for exemption of more than seventy-five percent (75%) of the frontage of any side of a corner lot, or 150 feet, whichever is greater.
