(A) The emergency outlet will be designed to handle runoff from the ten-year developed condition for the entire catchment area as defined in § 55.35(D). Acceptable methods that can be used for emergency outlets include but are not limited to concrete lined channel, bituminous lined channel, horizontally arranged orifices, and vertically arranged orifices. The method used must be designed to prevent any channel or bank erosion that would threaten the integrity of the channel or bank.
(B) The design consideration will be such that the amount of water anticipated to reach the pond will be able to leave at the same rate assuming the controlled outlet has been plugged. The necessary elevation for the emergency outlet will be such that the required volume of storage will be maintained.
