IMPACTS ASSOCIATED WITH <br /> NEW DEVELOPMENT <br /> • An increase in the amount (volume) of <br /> stormwater which runs of sites <br /> • An increase in runoff peak discharge rates <br /> from sites <br /> • A decrease in the time needed for runoff <br /> to reach the creek (time of concentration), <br /> particularly when pipes are installed to <br /> carry runoff directly to the creek <br /> • An alteration in creek channel equilibrium <br /> • An increase in the frequency and severity <br /> of flooding in the downstream creek <br /> corridor <br />
