Regulatory flood zone established by an approved PPRI in Dawn

All areas defined by the Prefectural Decree approving the PPRI are seized, including white areas (areas included in the study area but not subject to any regulatory constraints).
The PPR is a regulatory prevention dossier that informs populations and planners of risk areas and defines measures to reduce vulnerability. It was established by the Act of 22 July 1987, as amended by the Act of 2 February 1995. The PPR procedure is defined by Articles L.562-1 to L3562-9 of the Environmental Code.
the different zonings could be entered on several types of repositories

所有由批准PPRI的省行政法令所划定的区域均被纳入法定管控范围，其中包括空白区域（即纳入研究范畴但不受任何监管约束的区域）。PPR是一类监管型预防档案，用于向公众与规划人员通报风险区域，并明确降低脆弱性的相关措施。该档案由1987年7月22日法案确立，并经1995年2月2日法案修订。PPR的实施程序由《环境法典》第L.562-1条至第L.3562-9条作出规定。各类不同的分区区划可录入至多种类型的存储库中。
