Town streets and highways and may, when the public necessity and convenience
so require, procure and set in a proper manner such curbing as may
be deemed suitable and proper for the location, and shall construct
the gutters to correspond therewith, and may thereupon order the owner
or owners of the land and buildings fronting on such proposed sidewalk,
at their own expense, to raise, level or make such sidewalks on their
respective frontages according to the course, width, height and level
designated as aforesaid.
