Various state and local agencies in Maryland are requiring that the Soil Conservation Service Technical Release 55 be used to evaluate impact of urbanization on peak rates of discharge. In 1981, these agencies began to wonder if the procedures in TR-55 (SCS, 1975) were oversizing the outlet of stormwater management structures. Thus, the desired regulation of frequent events was not happening. In 1983, SCS in Maryland began a study to evaluate the concern of these agencies. The results of this study are presented.
