Right-of-way has been added to Metro's taxlot dataset so the code will need to be adapted to handle this next time this analysis is run

The overpass API occasionally times out which in my code throw a python error like the one below. Write some code to handle this that retries the download at least a couple of time if it fails

There are a set of constants that need to be used in separate bash and python scripts, explorer the possibility of bring the constants define in python into bash instead of assigning them separately in both scripts. I've looked into this a bit already and it seems that this is a not usual thing to do, but it was thinking the folks on the python IRC channel may be able to give me a better ideas as to whether this is a good idea or not.

the code contained within isn't actually executable and needs to be entered into the arcgis gui so the readme is a more appropriate place for these snippets

option should give the ability to transform the download data to a user supplied projection before writing it to shapefile
