[Amended 5-6-1995 STM by Art. 20; 5-6-2000 STM by Art. 13]
After deducting any federal or state grants from the total cost
of the laying out and construction of any main drains or of a system
or systems of sewerage and sewage disposal, the remaining cost shall
be paid by assessment of the cost of such public improvements to be
apportioned among the owners of property fronting on either side of
that portion of a public or private way in which such drain or sewer
lays, such assessment to be made according to the number of principal
structures on such land, and in the case of vacant land, or vacant
portions of built upon land, according to the number of buildable
lots into which such land may be divided under the Zoning Bylaw, but
no assessment in respect of such land which by reason of its grade
or level or any other cause cannot be drained into such sewer shall
be made until such incapacity is removed. The relative portion of
payment provided by this section may be changed from time to time
by vote of the town at any Town Meeting.
