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针对自然风险防范规划（PPR），《环境法典》第L562-1条将区划划分为两类：风险暴露区，以及虽未直接面临风险但可通过预先制定管控措施避免风险加剧的区域。 根据危险等级差异，每类区划均需遵循可强制执行的管控要求。本风险防范规划划定了两类区划： — 红区：指位于高危险区域的建成区，以及无论危险等级如何的非建成区（即需予以保护的洪水漫溢范围）。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活动，且需符合降低区域脆弱性的相关规定，同时仅可对既有建筑进行极为有限的扩建。红区可进一步细分为3个子区域： — UK：城市中心高危险区域 — RD：由康斯伯格（Constellium）开展危险研究并经行政长官于2015年1月5日核准的区划 — R：其他红区 — 橙区：指受中低危险影响的建成区，此类区域允许开展城市化建设活动，但不得加剧区域脆弱性。
