Since 2025, the SIAHVY, with state support, assists residents in adapting their homes to flood risk. The goal is to identify housing weaknesses against floods and propose tailored solutions to better protect people and property.
Recommended works can receive state aid up to 80% of their cost, capped at €36,000 per dwelling. SIAHVY also supports owners with administrative procedures. In 2026, the first construction projects began.
To provide a practical understanding, SIAHVY is launching a series of testimonials from residents of the Yvette basin. These accounts aim to show how individuals can act to make their homes more resilient to floods, sharing their experiences, the work undertaken, challenges faced, and the expected impact of future floods.
