Heavy snowfall has big disaster risk that is caused by climate change globally. Also domestically, heavy snowfall has considered as a risky disaster as it caused damage over past 30 years. Hence, in this study, snowfall frequency analysis is made to estimate requirements of de-icing material by region for the construction of customized snowfall disaster system considering the characteristic of the region. First, snowfall data for past 36 years from Snowfall Statistic Kit of Weather Observation Center which is Weather Station-affiliated is investigated and analyzed. Using the snowfall frequency, de-icing material requirements were estimated with the required amount basis by road area for 229 local governments. Therefore, city and county of Snow removal requirements (ton) was estimated by considering the road area ($m^2$), snowfall scenario frequency (1~5 cm, 5~10 cm, at least 10 cm), snow removal amount per unit area standard urban units ($kg/m^2$), as a result, total of 229 annual national target was found to be about 9 million tons. The municipality which requires the most De-icing Materials is urban area but some of the costal urban area tend to have less requirement. The results of this study is to estimate the standard requirements of De-icing Materials for the future.
