Because of the massive file sizes, I needed to use git lfs to commit all my files up to github, so you may need to install it if you don't have it already. I believe you can directly download a zip archive from the GH web interface, but if you still have issues, I can zip it and email.
This is a repo for all my coursework in this class, that I have caught up on, but you the issue we discussed today is in the FinalProject directory. In the weirdly nested ProjectFiles directory (don't ask me, ask ESRI), I have the Sammamish parking lots in the Default.gdb, the block groups from the census are pre-converted to NAD 1984 ... in the AnalysisOutput.gdb. This should be all you need to recreate the hurdle I couldn't clear earlier. I am essentially trying to determine the parking density on a census block level to better make fair comparisons to Seattle proper. I could very easily just attempt the same thing on an entire city level, but the aesthetic benefit of that granularity and the insight I hope to mine from it makes me a bit stubborn to completely abandon that approach.
There is other data in the SourceData folder if you feel so inclined to find a good middle ground that is successful, but mostly just throwing that fact out there just in case.
Very much appreciated sir.
