Rising Flood Risks: Protecting Homes in a Changing Climate
A year ago, devastating floods caused billions of dollars in damage. Fueled by climate change, the risk to properties is only increasing. This article explores how homeowners and builders can prepare for the growing threat of flooding.
The cost of Catastrophe
Extensive rains in Baden-Württemberg and bavaria in May and June 2024 led to notable flooding,resulting in fatalities and widespread destruction. The german insurance Industry (GDV) estimated the insured damage in both states at approximately $2.2 billion.
Did you Know?
Climate change is expected to increase the frequency and intensity of extreme weather events, making proactive flood readiness more critical than ever.
The Growing Threat
The GDV warns that such natural disasters are likely to become more frequent. due to climate change and thus more frequent weather extremes, damage of billions in billions is unavoidable,
said anja Käfer-rohrbach, the deputy GDV general manager, to the German Press Agency.
Risk Assessment
Insurers estimate that approximately 55,000 addresses in Baden-Württemberg,out of more than three million,are at risk of flooding. The Rastatt district faces the highest risk, followed by the Main-Tauber and Rems-Murr districts.Homeowners can assess their individual risk using the GDV’s online Flood Check.
Pro Tip
Regularly check and update your flood risk assessment, as climate patterns and local conditions can change over time.
New Construction: Planning for Resilience
Architect Sven Haustein from Bausparkasse Schwäbisch Hall offers advice on incorporating flood resilience into new construction projects.
- location: Consider potential flood risks when selecting a property, avoiding locations near rivers, floodplains, or slopes.
- Site Design: Design the house and terrain to facilitate effective water runoff.
- Construction: Opt for robust construction methods that provide protection against wind and weather.
- Roof security: Secure roofs with storm hooks, solid sheathing, and reinforced compounds.
- Basement Sealing: Conduct a soil report to inform basement sealing strategies.
- Water Management: Implement rainwater and wastewater management systems, such as cisterns, infiltration areas, and backflow preventers.
Existing homes: Retrofitting for Protection
Homeowners can take several steps to protect existing properties from weather extremes.
- Backflow preventers: install backflow preventers to prevent wastewater from re-entering the house during heavy rainfall.
- Roof Reinforcement: Secure older roof trusses with storm hooks.
- Window and Door Upgrades: Replace windows and doors with modern, weather-resistant models featuring special fittings and seals.
- Landscaping: Use landscaping techniques, such as dense hedges, drainage systems, and seepage areas, to divert water away from the house.
- Smart Technology: Install smart technology that automatically closes roller shutters upon severe weather warnings.
Reader Question
What are the most cost-effective retrofitting measures for flood protection?
Answer: Installing backflow preventers and improving landscaping for drainage are often the most affordable and effective initial steps.
The Role of Insurance
Standard homeowner’s insurance policies typically do not cover flood damage. Elementary damage insurance is necessary to cover losses caused by floods, landslides, snow pressure, earthquakes, or avalanches. There is ongoing debate about whether such insurance should be mandatory for property owners. Currently, 94% of buildings in Baden-Württemberg are equipped with elementary damage insurance.
