The design of stormwater management systems has become common practice in the last twenty years. These types of analyses are based upon the design and construction of isolated ponds based upon pre- and post-development flow rates, volumes and water quality parameters. These design principles have been codified in the various regulatory bodies that govern the process in the state of New Jersey and other jurisdictions. This paper addresses some of the engineering flaws that are rarely challenged by the profession. The micro- and macro-management of stormwater design is examined from a design engineer's viewpoint based upon the traditional establishment of design values and not just meeting regulatory edicts. The continuation of engineering design based upon design values that are not verifiable will only result in more wasted resources.
