It is not a brush. It is a model and it is embedded several units below the ground brush. Noclip won't show it properly because it is a model so sometimes it disappears from view (looking through the back plain of the mesh). The only way to make it seamless is to make the whole ground part of the mesh and then there will be problems matching that to other areas in the map where the mesh would have to try once again to match up with brushes. I will look again at it in radiant in case something else is happening that I didn't see the first time I checked it. I hid the plants to look at the fountain more closely but maybe it is one of the plants causing it.
