You are a Hydraulic Engineer tasked with designing a stormwater detention pond for a new urban neighborhood to prevent the creek downstream of this neighborhood from flooding during extreme rain events. The catchment area of this neighborhood is 0.8 km2, 40% of this catchment is covered with impervious surfaces, and the other 60% of the catchment has an average infiltration rate of 0.125 inches/hr.
