ORD 10.9.0.91
How can I add to an existing surface without having to redo all my clean-up? I have a boundary on my surface that helps me clip all the outside edges when editing a surface, but every time I need to add more data to areas outside this boundary I have either add vertices to my boundary or clean up the whole surface and create a new boundary both processes which are painful and long Thank you!
You can't. At least not that i've seen. We simply create all surfaces in one of many other user friendly software out there and import an XML file into the Microstation environment. Obviously if you don't have that at your disposal you're stuck using there extremely cumbersome and useless surface editing structure.
It is pretty useless. Can't even delete edge triangles unless you want to remove the rules.
I believe the trick and often overlooked/misunderstood step is adding a boundary using the tool below. You should be able to prevent edge triangles that way... works whether ruled or not. ORD seems to remember if added, so "remove" if you need another set.
It's almost the same process as this 5 minute V8i video. https://youtu.be/84QfqWjnql8 I'm not sure Bentley changed the functionality all that much in ORD.
Also setting the Edge Method to "From Boundary" mode is required... This should carry through any changes.
If you're using Field Books to generate Terrains, yes they are not "editable" from the Terrain tools, however if there's a linear feature set to "Boundary" in its Terrain Model Attribute, it can be adjusted, moved, etc... using the standard Modify (Drawing Tab e.g. Delete Vertex) tools with Civil Accudraw enabled to define elevation.

I asked in a previous post about extracting a terrain model boundary. I see you could do that before from the video. Where is that tool located in ORD. At least I could use the work flow in the video to get rid and keep the outer boundary as I need it.
The Add Boundary tool shown extracts the boundary automatically. The only time you need to recreate the boundary with that tool is when data is added outside of the original boundary.
