Abstract:The current formula of rainstorm intensity in Zibo City was compiled in the early 1980s. With the implementation of the spirit of Notice of the General Office of the State Council on the Construction of Urban Drainage and Waterlogging Prevention Facilities (GBF [2013] No. 23), significant changes have taken place in the intensity and distribution characteristics of regional short-duration heavy precipitation in the context of climate change and rapid urbanization. In December 2014, the new version of rainstorm intensity formula for the main urban area, which was compiled by Zibo Meteorological Bureau and reviewed by Zibo Meteorological Bureau and Zibo Housing and Development Bureau , began to be applied to practice. By comparing the old and new formulas with the urban development, and combining with the concept of urban low-impact development, the issues that require attention in design are discussed.
