576 LAWS OF MARYLAND [CH. 307

said sewer system, and provided, further, that when con-
nected, the length of agricultural property to be assessed
shall be limited to 150 feet; and provided, further, that no
lot shall be assessed on more than one side and corner lots
shall be assessed on that frontage toward which the build-
ing does or would naturally face, and that all lots shall be
assessed for their full frontage even though a sewer may
not extend along the full length of any boundary, except
in the case of agricultural property; and provided, further,
that in the case of irregularly shaped lots and shallow lots
fronting on more than one street, the Town may determine
upon and assess such length of frontage as it may deem
reasonable and fair. The Town shall change classifications
of properties from time to time as said properties change
in the uses to which they are put. The Town shall be
authorized and empowered to create sub-classifications of
any such class so as to reflect the benefit derived from such
sewerage system. Immediately upon the commencement of
the construction of the sewerage system, the Town shall
notify in writing all owners of said properties into which
class their respective properties fall and the charge deter-
mined 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 Town shall be final,
subject only to revision at said hearing. The Town is
hereby further authorized and empowered to make a
charge upon every building and place having a connection
with said sewerage system, said charge to be an annual
sewer service charge and to be based upon the quantity of
water used, or upon the amount of the water bill, or upon
the number and size of sewer connections, or upon the
number and kind of plumbing facilities in use in the prem-
ises connected with the sewerage system, or upon the
number or average number of persons residing or working
in or otherwise connected with such premises, or upon the
type or character of such premises, or upon any other
factor affecting the use of the sewerage system and sewage
treatment plant, or upon any combination of the foregoing
factors, as the Town, in its discretion, shall determine to
be the most equitable basis for such sewer service charge.
All assessments and charges, except connection charges,
shall be uniform for each class of property and for each
sub-classification thereof throughout the Town. Such as-
sessments and charges shall be subject to change annually
