Design storm event means a hypothetical storm event, of a given frequency interval and duration, used in the analysis and design of a stormwater facility.

Design storm event means a hypothetical storm event, of a given frequency interval and duration, used in the analysis and design of a stormwater facility. The estimated design rainfall amounts, for any return period interval (i.e., 2-yr, 5-yr, 25-yr, etc.,) in terms of either 24-hour depths or intensities for any duration, can be found by accessing the following NOAA National Weather Service Atlas 14 data for Tennessee: http://hdsc.nws.noaa.gov/hdsc/pfds/ pfds_map_cont.html?bkmrk=tn. Other data sources may be acceptable with prior written approval by TDEC Water Pollution Control.

Design storm event means a hypothetical storm event, of a given frequency interval and duration, used in the analysis and design of stormwater facility. The estimated design rainfall amounts, for any return period interval (i.e., 2-year, 5-year, 25-year, etc.,) in terms of either twenty-four (24) hour depths or intensities for any duration, can be found by accessing the following NAA National Weather Service Atlas 14 data for Tennessee: http://hdsc.nws.noaa.gov/hdsc/pfds/pfds_map_cont.html?bkmrk=tn. Other data sources may be acceptable with prior written approval by the city engineer.
