1784 ARTICLE 7.

small acreage, industrial or business, and sub-division property. Imme-
diately upon the commencement of the water supply project, the Mayor
and Common Council of Manchester are empowered and directed to fix
and levy benefit charge upon all property abutting upon said water
main, in accordance with the classification, and shall in writing notify
all owners of said properties into which class their respective properties
fall and the charge determined upon, naming 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 the case of vacant or unimproved
property, posted upon the premises. The classification of and benefit
assessed against any property as made by the Mayor and Common. Council
of Manchester shall be final, subject only to revision at said hearing. The
Mayor and Common Council of Manchester may change the classification
of properties from time to time, as said properties change in the uses to
which they are put. Said benefits shall be levied for water supply con-
struction upon the number of front feet abutting upon the street, lane,
alley or right-of-way in which die water main is placed; provided, how-
ever, that no lot shall be assessed on more than one side', that comer lots
in this class shall be assessed on that frontage towards which the building
does or would naturally face, and that all lots in this class shall be assessed
for their full frontage even though a water main may not extend along
the full length of any boundary; and, provided, further, that in the case
of irregular shaped lots, and shallow lots fronting on more than one street,
the Mayor and Common Council of Manchester may determine upon for
assessment, and may assess, such length of frontage as they deem reason-
able and fair. Front foot benefit charges for water supply construction
shall bo uniform for each class of property throughout the town. The
amount of the charge per front foot for each class of property for water
mains shall be determined from time to time by the Mayor and Common
Council of Manchester as costs and conditions require. Said benefit
charges shall be paid annually beginning in the year such construction
is begun, by all properties loca.ted as above specified, 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 in the sub-division or business or industrial class may, at his
option, extinguish at any time said benefit charge by the payment, in
cash, of an amount which if put at interest at 3 1/2 per cent., compounded
annually, would yield an annuity equal to the annual assessments for the
period for which the bonds have, at the time the option is exercised, still
, to run. The Mayor and Common Council of Manchester shall at any
time permit a connection with a waiter main by a property owner whose
property does not abut on said water main, and who has not previous
thereto paid a benefit for the construction of said water main, provided
the said Mayor and Common Council of Manchester shall first determine
the classification of said property, and a front foot charge to be paid by
said property owner as though his property abutted on said water main,
