ALBERT C. RITCHIE, GOVERNOR. 503

will be heard. Such notice may be mailed to the last known ad-
dress of the owner, or served in person upon any adult occupy-
ing the premises, or in the case of vacant or unimproved prop-
erty posted upon the premises. The classification of and as-
sessment 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 classification of prop-
erties 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 number of front feet abut-
ting 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 sub-division 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 fronting on more than one street in which
a water 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 frontage, the Mayor and Council
may assess such length of frontage 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 prop-
erties located as above specified, for a period of years co-exten-
sive with the period of maturity of the bonds out of the pro-
ceeds 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 slim,
of the proportion of the estimated cost of the project, of which
the construction abutting upon his property is a part, repre-
sented by the number of front feet which he is assessed, with
interest at the rate of six per cent per annum from the date of
said -lew, less any annual payment that may have been made
