Massy's flood claim denied

The request for official recognition of floods in Massy on August 27, 2026, as a natural disaster has been rejected. The commune is listed in the annex of refusals from an interministerial decree published in the Official Journal on October 23, 2026.

Reason for rejection

The decision is based on the intensity of the rainfall, which the decree states had a return period of less than ten years. This does not meet the criteria for an exceptional event, affecting the eligibility for specific disaster compensation.

Insurance implications

Residents affected by the floods must now rely on their individual insurance contracts for compensation. The legal natural disaster guarantee requires an official decree recognizing the event, the commune, and the period, which is not the case here.

Steps for affected residents

Those who experienced damage should contact their insurer directly. They must provide details about the damage and check which guarantees in their contract apply. Documentation such as photos, invoices, and estimates will help support their claims.

Municipal process

The City of Massy had prepared two separate files for the floods and for land movements related to drought. The rejection only affects the flood-related claims, which are being reviewed separately from the drought-related issues.

Other communes recognized

An interministerial decree published on October 23 recognizes three natural events in Allemond and Saint-Christophe-en-Oisans. These include an avalanche in Allemond and two flooding incidents in Saint-Christophe-en-Oisans.

Insurance coverage details

For property owners in recognized communes, the natural disaster guarantee applies to direct material damage from the event, provided legal and contractual conditions are met. This includes homes with multi-risk insurance, and possibly some movable property and vehicles.

Rejection in other communes

Five other communes in the Isère department had their requests denied. The reasons include lack of meteorological criteria for exceptional events and damage caused by man-made structures rather than natural causes.

Next steps for residents

Residents in denied communes should continue to work with their insurers, checking their contracts and gathering necessary documents. They are advised to keep all records of damage, even if repairs have started, to support any future claims or disputes.

Declaration deadlines

Those in recognized communes must declare their damage within 30 days of the decree's publication or as soon as they become aware of it. They must provide detailed information and supporting documents to their insurer.
