For natural PPRs, the Environmental Code defines two categories of zones (L562-1): risk-exposed areas and areas that are not directly exposed to risks but where measures can be foreseen to avoid exacerbating the risk. Depending on the hazard level, each area is subject to an enforceable settlement. This PPR defines 2 types of zones: — red zone corresponding to the urbanised areas located in strong hazard and non-urbanised areas, regardless of the level of hazard (fields of expansion of floods to be preserved). In these areas, only new constructions and developments directly linked to the management, maintenance and operation of space, subject to compliance with requirements to reduce vulnerability and very limited extensions of existing buildings. It is subdivided into 3 sub-areas: — UK: area of strong hazards in urban center — RD: zoning of the hazard study produced by Constellium and validated by the Prefect on January 5, 2015 — R: other red zone — orange area corresponding to urbanised areas affected by medium or low hazard where urbanisation is allowed provided that the vulnerability is not aggravated针对自然风险预防规划（PPR），《环境法典》于L562-1条款中划定了两类区域：风险暴露区，以及未直接面临风险但可采取措施规避风险加剧的区域。 依据风险等级的不同，每类区域均需遵循可强制执行的管控规则。该自然风险预防规划划定了两类区域： — 红区：对应处于高风险中的城市化区域，以及无论风险等级如何的非城市化区域（即需予以保护的洪水漫溢范围）。在此类区域内，仅允许开展与空间管理、维护及运营直接相关的新建工程与开发项目，且需符合降低区域脆弱性的相关要求，同时仅可对既有建筑进行极为有限的扩建。该红区划分为3个子区域： — UK：城市中心高风险区域 — RD：由康齐利姆（Constellium）编制、2015年1月5日经法国省长审定通过的风险研究划定区域 — R：其余红区 — 橙区：对应受中低风险影响的城市化区域，此类区域允许开展城市化建设，但不得加剧区域脆弱性
