pre-development hydrology definition
pre-development hydrology means (a) for new development, the runoff curve number determined using natural conditions hydrologic analysis based on the natural, undisturbed condition of the site immediately before implementation of the proposed development; and (b) for redevelopment, the existing conditions hydrograph may take into account the existing development when defining the runoff curve number and calculating existing runoff, unless the existing development causes a negative impact on downstream property.
pre-development hydrology means (a) for new development, the runoff curve number determined using natural conditions hydrologic analysis based on the natural, undisturbed condition of the site immediately prior to the implementation of the proposed development; and
pre-development hydrology means the combination of runoff, infiltration and evapotranspiration rates, volumes, durations and temperatures that typically existed on the site before human-induced land disturbance occurred.
