Frontignan-Plage's coastal paradox

Frontignan-Plage is a narrow coastal area between the Mediterranean Sea and marshes, where the sea is encroaching, flood risks are real, and climate models suggest an uncertain future for homes. Yet, despite these dangers, properties in this area continue to sell for high prices.

High property prices despite risks

In February 2025, the Hérault Tribune reported that the average price per square meter in Frontignan-Plage reached 3,880 euros, significantly higher than the 2,720 euros for the entire commune. This price difference highlights the continued demand for properties exposed to rising coastal risks.

A broader trend along the French coast

This situation is not unique to Frontignan-Plage. According to the book Recul du trait de côte et immobilier littoral, published by Editions du Moniteur, similar patterns are observed across much of the French coastline. The book explores how coastal erosion impacts property values and market behavior.

Expert analysis of coastal property values

Clara Perez, an expert in real estate evaluation at the IPFEC firm, studied the effects of coastal erosion on property values. Her research indicates that despite the risks, the market still places a high value on proximity to the sea. She notes that property prices along the waterfront remain significantly higher than those inland or in the second row of properties.

Market behavior and collective denial

Perez attributes this trend in part to a form of collective denial among buyers and real estate professionals. Many do not fully recognize the risks posed by coastal erosion and continue to prioritize the advantages of coastal living, such as direct beach access and a desirable environment, over the potential dangers.
