Unfortunately I cannot share that particular map, but I found a way to resolve the problem. The fix was to republish the utility services with a data transformation specified. I would have thought that both the drawing location and the selection location would be identical with both shifted on the basemap do to a lack of a data transformation being specified when the data was published as a service. Why would it be drawn in one location and selectable in a different location when it is the same data from the same service? Is this a bug in the map services?
The utility data is stored in Texas State Plane 1983 South Central US Feet in the geodatabase but the service is published in Web Mercator. The basemaps are the Esri default basemaps that are in Web Mercator as well. I know using the data transformation improves the accuracy of the utility data overlay, but it also slows down the rendering of the utility data.
