Random Breaklines in Terrain

 I have been trying to create terrains for a bridge replacement project with channel, roadway, and trail work. It has all been modeled using Openroads. Whenever I create a terrain of the channel area, random breaklines show up in the terrain, which inserts numerous vertices and inflates the file size. We are sharing the Land XML with our sub-consultant working on the H&H and the file size has been an issue for them. I have no idea where these breaklines are coming from. It looks like some of them are due North-South/East-West. Any help on how to get rid of these is much appreciated.
