A location that is prone to flooding. This tag is used to indicate areas or features (roads, points of interest, etc.) that are frequently or temporarily affected by floods (e.g. after heavy rains), presenting a hazard to navigation or safety.

Usage:

  • For Roads and Road Signs: The hazard=flooding tag can be applied to roads and road signs to indicate that the road is prone to flooding. It helps raise awareness among users and can aid in route planning during periods of heavy rain or flood events.
  • For Area Hazards: The hazard=flooding tag can also be used to identify areas that are prone to flooding, such as flood plains. This usage helps to highlight the potential hazard in a broader context and capture community knowledge of local flood conditions of historic or recurring flood events.
  • In Combination with boundary=hazard: Ideally the hazard=flooding tag is used in combination with the boundary=hazard tag, it denotes a defined boundary or area where the hazard of flooding exists. This combination can be applied to mark specific regions, neighbourhoods, or zones that are at risk of flooding. It provides a more precise representation of the affected area.

Please note that the hazard=flooding tag should only be applied to areas or features that are susceptible to flooding. It is essential to rely on accurate and up-to-date information to ensure the tag's correct application, for this reason, is important to either include the source (when relevant) that determined this area to be susceptible to flooding or a note.
