Query elevation data within python script

Greetings, I'm new to ArcGis and this community.  Hope this isn't a dumb question.  In a python script I'm loading a polygon shapefile and creating a buffer around each polygon, writing this to a new file.  This all works great.  But the size of the buffer needs to depend on the ground elevation of the polygon. 

 

So here is my question:  What approach should I take to get the elevation of a polygon? 

 

I've tried the SummarizeElevation tool, but only works on 1000 polys at a time, and it's slow.  The AddSurfaceInformation_3d is just throwing a 999999 error for me (and yes I tried repair).

 

Also note, the elevation doesn't need to be super accurate.  Sampling the first point on the polygon would be sufficient.

 

Thanks!
Walter
