I did, but I used an intersect layer, and the info just shows up with the other popup info, under the grade levels. I can make the utilities their own districts, but I don't want the view to zoom to those, I only want the global utility information displayed for the address.
One problem I noticed is that there are different utilities for the same address, based on what grade band we're looking at. For example, the elementary boundary is close in, but the high school boundary is much larger, and covers different utility districts. So I think I need to keep that data totally separate and figure out how to display it strictly for the address that's entered in the search.
