I should note that the CoV does have high quality property parcel data
available, in case that's of any use for the import. I suppose in theory
it's possible to use it to identify the edge of the property that
borders the street on which it sits, and place the node in the center of
that edge, for instance. I don't know if this kind of fiddlery is
considered 'good' or 'bad', and I don't know if my weak GIS/coding
skills would be enough to achieve it :)
