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. The regulation of this RPP defines 2 areas: — Red zones (R) correspond to areas located in severe weather and non-urbanised areas, No matter the level of hazard (fields of expansion of floods to be preserved) In these areas, are not authorised that new constructions and developments directly related to management, maintenance and operation of space, subject to compliance with requirements to reduce their vulnerability and very limited extensions of existing buildings. A specific Ru zoning corresponds to the areas of strong hazard in the urban centre. In these areas, the replacement and measured extension of constructions may be permitted to the extent that they do not generate no significant increase in the vulnerable population and where new housing are designed in such a way as not to suffer any damage. — Orange areas (O): urbanised areas affected by medium or low risk where urbanisation is allowed provided that the vulnerability is not aggravated针对自然风险防护区（natural PPRs），《环境法典》（Environmental Code）于条款L562-1中划定两类区域：风险暴露区，以及虽未直接面临风险但可预先采取措施规避风险加剧的区域。根据危险等级差异，每类区域均需遵循可强制执行的管控细则。本RPP（RPP）的管控规则划定相关区域：—— 红区（R）：对应受极端气象影响的非城市化区域，无论危险等级高低（如需保留的洪水漫溢范围）。此类区域禁止开展与空间管理、维护及运营直接相关的新建工程与开发活动，仅可在符合降低区域脆弱性相关要求的前提下，对既有建筑开展极为有限的扩建。特定Ru区划对应城市中心的高危险区域，此类区域内建筑的翻新与适度扩建可获许可，但需满足两项条件：不会造成脆弱人口规模的显著增长，且新建住宅的设计需确保其不受灾害损害。—— 橙区（O）：受中低风险影响的已城市化区域，可开展城市化建设活动，但不得加剧区域脆弱性。
