ing also in said notice a time and place when and at which
said owners 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 vacant or un-
improved property posted upon the premises. The classifica-
tion of an assessment against any property as made by the
Mayor and Council shall be final, subject only to revision at
said hearing. The Mayor and Council may change the classi-
fication of properties from time to time, as said properties
change in the uses to which they are put. Said assessments
shall be levied for both water supply and sewerage construction
and shall be based for each class of property upon the num-
ber of front feet abutting upon the street, lane, alley or right-
of-way in which the water pipe or sewer is placed; provided,
however, that no lot in a subdivision property shall be assessed
on more than one side, that corner lots in this class shall be
assessed on that frontage towards which the building should
naturally face, and that all lots in this class shall be assessed
for their full frontage even though a water main or sewer
may not extend along the full length of any boundary; that
in the case of irregular shaped lots, and shallow lots front-
ing on more than one street in which main or sewer is placed,
the Mayor and Council may assess such length of frontage
as they deem reasonable and fair; and provided, further, that
in the case of small acreage and agricultural property, where
a water main or sewer does not extend along the whole front-
age, the Mayor and Council may assess such length of front-
age as they deem reasonable and fair. Front foot assessments
for water supply and sewerage construction shall be uniform
for each class of property throughout the town. The amount
of the assessment per front foot for each class of property
for water mains and sewers shall be determined annually by
the Mayor and Council as costs and conditions require. Said
assessments shall be paid annually beginning in the year such
construction is begun, by all properties located as above speci-
fied, for a period of years co-extensive with the period of
maturity of the bonds out of the proceeds of which such
construction was done; provided, however, that any owner of
property may, at his option, within one year from the time
said front foot assessment or benefit charge is levied extinguish
the same by the payment in cash, in one sum, of the propor-
tion of the estimated cost of the project, of which the con-
struction abutting upon his property is a part, represented
