There will be 50 to 200 streets of new data used for new
subdivisions. I suppose that I could have created sets of data for
"These might be renamed", "These might be imported" , "These might be
adjusted" , "These might be deleted" (Because a diff doesn't identify
which one is right) , then not bothered to mention the additional review
which would indeed just be a local project.
If this is deemed not to be an import, then we will begin immediately.
