(A) The development of a comprehensive storm water management system requires providing two separate and distinct drainage systems–the minor system and the major system.
(B) The minor drainage system is for collecting and transporting run-off from frequently occurring storms. It includes open channels, street curbs and gutters, and underground storm sewers, manholes, catch basins, culverts, and the like. This system's purpose is to lessen or eliminate inconveniences and safety and health hazards associated with frequent storms. Except where otherwise indicated, the criteria included in these regulations are directed to the design of the minor drainage system.
(C) The major drainage system is to insure that storm water run-off which exceeds the capacity of the minor drainage system has a route to follow that will not cause substantial damage. It must be recognized that the major drainage system exists even when it is not planned and whether or not physical facilities are intelligently located in respect to it.
