The PPRn can cover a single natural hazard or multiple hazards, and can cover one or more municipalities. Its prohibitions and restrictions on construction in natural-hazard areas apply to all construction, both public and private-sector. While the PPRn are created by the national government, they are developed in close consultation with regional and municipal officials, and the public. Beyond specifying construction conditions, the PPRn are intended to inform land-use planning decisions in areas vulnerable to natural hazards.
