So the file you linked here is just a KML link out to a different KML file which I've attached. That file is also unfortunately just a set of network links (KML allows for network links to different servers). CalTopo doesn't support KML files with network links. However it appears that the service you're looking at supports WMS and is running a WMS server. We do support custom WMS layers at the Pro level. I haven't quite gotten the WMS layer importing cleanly yet but it is a format that our server can digest. I'll kick it over to a developer and have them take a look.
