front feet abutting upon the street, lane, road, alley or
right-of-way in 'which the water pipe or sewer is placed;
provided, however, that in the case of any irregular shaped
lot abutting upon a road, street, lane, alley or right-of-way
in which there is or is being constructed a water main or
sewer at any point, said lot shall be assessed for such front-
age as the Commission may determine to be reasonable and
fair; and provided further that no lot in a sub-division
property shall be assessed on more than one side, unless
said lot abuts upon two parallel streets, that corner lots
may be averaged and assessed upon such frontage as the
Commission may deem reasonable and fair, and that all lots
in this class shall be assessed even though a water main or
sewer may not extend along the full length of any bound-
ary; and provided further, that no land so classified as
agricultural by this Commission shall be assessed a front
foot benefit when said agricultural land has constructed
through it or in front of it a sewer or water main, until such
time as the water or sewer connection is made, and when
so made and for every connection such land shall become
liable to a front foot assessment for such reasonable front-
age not exceeding three hundred (300) feet, or as may be
determined by said Commission, and shall be immediately
assessed at the rate of assessment determined by said Com-
mission for agricultural land. Front foot benefit charges
for water supply and sewerage construction shall be as
nearly uniform as is reasonably practical for each class or
sub-class of property throughout each district for any one
year and no benefit charge, once levied, shall be increased;
provided, however, that whenever the Commission acquires
an existing system other than a municipal system, the con-
struction of which has been added in whole or in part to
the purchase price of land or lots abutting upon said system
and which contribution the Commission has determined to
be a factor in the cost to the Commission of such system,
the Commission may, in its discretion, levy a front foot
assessment less than the uniform front foot assessment
levied in the remainder of the sanitary district in which
said system is located. The amount of the charge per front
foot for each class of property for both water mains and
sewers may be reduced from time to time by the Commis-
sion in its discretion, if costs and conditions are deemed
by it to justify such reduction. Said benefit charge shall be
paid annually by all properties located as above specified,
for a period of years co-extensive with the period of ma-
turity of the bonds out of the proceeds of which such con-
struction was done. The Commission shall at any time
