The owner of land abutting on any highway, street
or public place in front of whose premises an artificial sidewalk
has been or shall be constructed shall, at his own cost and expense,
maintain and repair such sidewalk in front of such premises.
Upon the default or neglect of any owner of
land to maintain or repair any sidewalk in front of his premises for
15 days after written notice from the Board of Selectmen to do so,
the Board may repair such sidewalk and the expense of such repair
shall be a lien upon the premises adjoining such sidewalk, provided
that the Board of Selectmen shall cause a certificate of lien against
such premises to be recorded in the Town Clerk's office within 60
days from the completion of such repair, and such lien shall be prior
to all other liens except tax liens.
