Your workflow looks pretty legit, but yeah I see what you mean about unnecessary vertices. I would add this one step at the beginning of your process:</P><P></P><P><A class="link-titled" href="http://pro.arcgis.com/en/pro-app/tool-reference/cartography/simplify-polygon.htm" title="http://pro.arcgis.com/en/pro-app/tool-reference/cartography/simplify-polygon.htm">Simplify Polygon—ArcGIS Pro | ArcGIS Desktop</A>&nbsp;</P><P></P><P>Use the POINT_REMOVE algorithm.
