Objectives of current designs for urban storm runoff systems specify: draining all surface water (for 25 year rain storms) from the entire design area, and removing this water with less than 15 minutes of surface travel time. These objectives require an average investment of 7,600 dollars per acre in conduit systems. Reluctance of a majority of the populace to commit needed financial support coupled with concern for the impacts of such systems on urban environmental quality deemed examination of the above objectives necessary. This examination has been made including review of effects of urbanization on physical hydrology and the hydrologic cycle. (Author)
