It would be great if ORD had the capability to connect a channel directly to an On Grade Inlet to be able to calculate spread and bypass at the inlet. Currently the workaround is to connect the channel to a Generic Outfall at the edge of the inlet and then inject the flow to the inlet. This process is time consuming, cumbersome, and could easily lead to flows being missed. ORD does allow for channels to be attached to sag inlets, but this would not have any bypass and would not be applicable to On Grade inlets. InRoads could accomplish this by placing a Median Drop inlet in the channel. This fix would be greatly appreciated.

I would like to add that tracking all the flows to various outfalls is multiplied by the number of scenarios one has to run (10 yr, 50 yr, 100 yr). This makes the process even more time consuming and introduces the possibility for error. Additionally, you cannot attach multiple channels to sag inlets so outfall nodes are needed at these locations as well.
