What this layer shows

The hazard map under the EU Floods Directive for the medium-probability scenario: usually the 1-in-100-year event. Unlike a designated flood plain the hazard map is not an ordinance: it shows where water would stand, and it is the technical basis from which a designation later follows.

Water and flooding

The water-law side of a site: drinking-water and medicinal-spring protection areas with their zones, designated flood plains and flood hazard maps, Saxony’s flood-generation areas, and bathing waters. Flood plains designated under § 76 WHG are subject to the construction safeguards in § 78 WHG, including statutory exceptions and possible approvals by the competent authority. The map does not replace the authority’s assessment of a specific proposal.
