§ 6-620 Sidewalks, payment for construction. Whenever the owner or
occupant of lands adjoining a street constructs along such street a
sidewalk of stone, cement, brick or other similar materials to be
approved by the board of trustees, and the board consents to bear a
portion of the expense of construction thereof, the board of trustees
may pay to such owner or occupant a sum to be fixed by the board of
trustees not exceeding one-half of the actual and necessary expense of
constructing such sidewalk. Before the board of trustees shall so
consent to bear a portion of the expense of construction of any such
sidewalk, it shall fix the proportionate amount that shall be paid by
the village for all walks of the same kind which may thereafter, with
such consent, be constructed therein; and such proportionate amount may
be changed from time to time thereafter by the board of trustees, but at
no time within one year from the date of the last fixing or changing
thereof.
