You'd have to be a complete moron to pour a sidewalk
without knowing for sure, via a survey, where the line is.


Many people make assumptions. You see a fence, so the assumption is that it
is on the property line. Later you want a sidewalk, so you frame it out to
the assumed property line. Dumb or not, it happens every day. I wonder how
many people think they own out to the curb at the street?
