Line C is similar to Line A and Line B. The storm drain located in Sedco Boulevard, will carry a 10 year flow of 80 cfs in a 30 inch diameter RCP. The open channel portion of the line will be a concrete trapezoidal section with a bottom width of 2 feet, a depth of 3 feet and the capacity to carry a 100 year peak flow of 125 cfs.

A look down what could be beautiful Sedco Boulevard.

I could find no drainage other than the roadway.
