Where is Drainage inlet longitudinal slope measured from with respect to inlet? Incorrect slope

Hello, 

I am currently placing inlets, to automate getting the longitudinal values. I am attaching a reference terrain to the inlets. I had merged my existing and proposed terrain into one combined final terrain. I am placing my inlets. The longitudinal slopes that the inlet is pulling is off from my measured slopes in the file. My measured in 5%, where the slope generated from the inlet is 10%.

I have doubled checked that the merged terrain is correct with the proposed roadway model. Is there any way to check where the inlets are measuring from? 

Thanks, 

Emily
