Court having jurisdiction.

430. for the purpose of paying the interest and principal of the
bonds issued by said Commission as in this sub-title provided for
the water supply or sewerage systems to be constructed, purchased
or established under this sub-title, the said Commission is hereby
empowered to establish a proper and reasonable charge for connec-
tion with said water supply or sewerage system so to be constructed,
purchased or established as aforesaid, and to fix an annual assess-
ment on all properties, improved or unimproved, binding upon a
street, road, lane, alley or right-of-way in which a water main or,
sewer has been built The said annual assessment shall be made
upon the front foot basis, and the first payment shall be collected
during the year in which the construction is completed on the water
supply or sewerage systems, or in which the systems are purchased
or acquired. The said Commission for the purpose of assessing
benefits shall divide all properties binding upon a street, road, lane,
alley or right-of-way, in which a water pipe or sanitary sewer is to
be laid, into four classes, namely: Agricultural, small acreage, in-
dustrial or business, and subdivision property, and the Commission
may subdivide each of said classes in such manner as it may deem to
be in the public interest. Whenever any water supply or sewerage
project in said sanitary district or sanitary districts shall have been
completed by March 31st, in any one year, regardless of when said
construction was commenced, then the said Commission shall fix
and levy a benefit charge as to the first day of January of the year
in which the project was completed upon all property in said sanitary
district abutting upon said water main or sewer, in accordance with
the classification or subdivision thereof, and shall in writing, notify
all owners of said properties into which class and subdivision their
respective properties fall and the charge determined upon, naming
also in said notice a time and place, when and at which time said
owner will be heard. Such notice may be mailed to the last known
address of the owner, or served in person upon any adult occupying
the premises or in case of a vacant or unimproved property posted
upon the premises. The classification of and the benefit assessed
against any property as made by the Commission shall be final, sub-
ject only to revision at said hearing. The Commission may change
the classification of property from time to time as said properties
change in the uses to which they are put. Said benefits shall be levied
for both water supply and sewerage construction and shall be based
for each class of property upon the number of 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 frontage as the Com-
mission may determine to be reasonable and fair; and provided
further that no lot in a subdivision 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, aitd 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 boundary; and provided further
that land so qualified as agricultural by this Commission shall be
