Regions along the Mediterranean coast are particularly vulnerable, with the Region of Murcia having the highest percentage (17%) of homes affected by flood risk.
Key Areas of Concern
Several major cities in Spain have a substantial number of homes in flood-prone areas:
- Murcia: 60,775 homes (28.6% of total)
- Valladolid
- Palma
- Girona
- Cartagena
Some smaller towns, like La Algaba (Seville), Deltebre (Tarragona), and Santoña (Cantabria), have over 70% of their streets in flood risk zones.
Using the Flood Risk Map Viewer
The embedded viewer allows you to:
- Zoom in on specific areas of interest

Importance of Flood Risk Assessment
Understanding flood risks is crucial when moving to Spain because:- It affects property values and insurance costs
- It helps in making informed decisions about where to live

Recent events highlight the importance of this information. In October 2024, severe flooding in Valencia resulted in over 200 fatalities and significant infrastructure damage across multiple regions.
Flood Risk Management in Spain
Spain has been implementing the European Directive 2007/60 on flood risk assessment and management. This includes:
- Identifying areas with potentially significant flood risk
- Developing flood hazard maps
- Creating flood risk management plans
These efforts aim to improve awareness and preparedness for flood events throughout the country.
Historical Flood Events in Spain
Spain has a long history of significant flooding events that demonstrate the importance of flood risk awareness:
- 1957 Valencia Flood: A catastrophic event known as "La Gran Riada" that led to major changes in flood control infrastructure
- 1962 Vallés Floods: Severe flooding in Catalonia that affected multiple municipalities
- 1983 Spanish Floods: Widespread flooding that impacted various regions across the country

- Hydraulic Public Domain: Includes land covered by water during maximum normal rise levels
- Easement Use Area: A 5-meter strip on both sides of the riverbed to protect ecosystems
- Police Area: A 100-meter wide strip with strict usage regulations
- Preferential Floodway: High-hazard area with concentrated flood flow
- Flood-Prone Area: Zones covered by 500-year flood events
Key Flood Risk Management Objectives
The Spanish government's flood risk management strategy focuses on:
- Improving land use and urban planning policies
- Establishing compatible activities in flood-prone areas
- Implementing strict land-use limitations
- Protecting human life and infrastructure
- Ensuring transparent risk communication
Land-Use Restrictions by Zone
| Zone Type | Key Restrictions |
|---|---|
| Preferential Floodway | Strict limitations on most land uses, only non-vulnerable activities permitted |
| Flood-Prone Area | Limitations on vulnerable activities, less restrictive conditions |
| Special Flood Risk Municipalities | Additional regulations for areas with high flood likelihood |
