All,
I kept the files in their orginal .zip file. (only way to download them). No
luck when using as a background or loading as data. As per Don's suggestion I
uploaded a zip file to IDV support.
I played around with this some. I downloaded one of the zip files (El
Paso something or other), I extracted the .prj file, and edited it to
change "Foot_US" to "foot", and added it back to the zip file. With
this, I was able to display the data, but it shows up in the wrong
place. So, either there's a bug in the prj parsing code, or the state
planar projection is not defined completely by all the other parameters.
Unidata can look into this for you.

Greetings Roderick,
Can you try putting all of the files into a .zip file and load that into
the IDV?
Thanks!

All,
I am attempting to overlay some data on maps produced by our regional mapping
authority. When I open the files in IDV I only have a line.
How do I get IDV to recognize this file, if possible?
I have been working with the projection setting but nothing has worked. I am
assuming this projection is not one IDV can ingest.

The maps are shapefiles. Here is the info from the .prj file
