   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.
