An industrial park with flat-roofed buildings, large parking lots, and little open area has a drainage basin area of 398 ac. The 25-year rainfall event (the amount that would on an average occur once in 25 years) has a precipitation intensity of 2.382 in./h. If the C factor is 0.75, what is the maximum rate that overland flow will drain from the industrial park?
