Here is a list of 126 coastal cities where any new construction may be banned.

The government has published in the Official Journal the names of 126 municipalities that will have to take measures to adapt to coastal erosion.

The government has published the names of 126 French municipalities that will be required to prioritize adapting to coastal erosion exacerbated by global warming and human pressure, a list of new urban planning restrictions that are not unanimous. Due to coastline retreat on about a fifth of France’s coastline (excluding Guyana), in line with the National Coastal Erosion Index, the Climate and Resilience Act 2021 provides new provisions for frontline municipalities facing rising sea levels. level and increase in storms and sea flooding.

Mayors will have to draw up retreat risk maps in 30 and 100 years, a map that will serve as the basis for new land-use planning rules, all the way to building bans. Initially, these are 126 municipalities (see full list below) in mainland France and overseas territories, according to the list published on Saturday in the Official Journal, which will be reviewed at least once every nine years. Most of them are located on the coast of the Atlantic Ocean and the English Channel (in particular, 41 in Brittany, 16 in Normandy, 31 in New Aquitaine).

“These 126 so-called priorities are laughable compared to the 864 municipalities under threat,” Elodie Martini-Cousti of the NGO France Nature Environment says in an interview with AFP.

According to official figures, 864 municipalities are “more vulnerable” to sea flooding, a phenomenon of temporary flooding of coastal areas by the sea, especially during storms, which will increase with rising sea levels caused by global warming. And these coastal floodplains are home to 1.5 million people. But “we allow too much building on the coast” and the new regulations are “not geared to the challenges,” says Elodie Martini-Cousti.

New construction will be prohibited

Those of the 126 municipalities that do not yet have a “coastal risk prevention plan” will have to map the evolution of the coastline in 30 and 100 years. “It was interesting for me to know the vulnerabilities of the municipality and to be able to tell the population: be careful, we are in very sensitive areas,” comments Xavier Martin, Mayor of Tregastel (Côte d’Armor), welcoming the state funding of 80% of the cost of these maps, which he sees it as a tool for “risk prevention”.

“If we say that we are reconstructing (the city center) and that in 20 years it will be under water, is it useful to renovate it today, shouldn’t we think that we should look at it differently?” he told AFP. In areas subject to a 30-year horizon, new construction will be prohibited, but with exceptions for expanding existing buildings or installing utilities and new economic activities requiring “close proximity” to the sea. Areas over a 100 year horizon remain buildable with a commitment to demolish in the long term as the threat approaches.

To allow local governments to start this new land development, the regulation, published in early April, defines ways for governments to acquire endangered property and establishes a new type of lease granted by the state or municipalities for land, commercial premises. or recreational parks in the relevant lane (lease for a period of 12 to 99 years with early termination depending on erosion).

Some “legal ambiguities”

But the National Coastal Elected Officials Association deplores some “legal uncertainty” that “involves a lot of controversy that could be detrimental to the achievement of the stated goals.” Some local officials are also questioning the new restrictions placed on local urban development plans and are pointing the finger at funding problems.

“Progress made (as a result of the listing) remains largely at the level of increased risk awareness,” says Vincent Bauedin, who is in charge of shoreline management in the Community of Great Lakes Municipalities, which includes the coastal city of Biscarosse (Landes). He is concerned about funding the relocation of endangered objects. “There are questions about who is supporting the relocation of the population from the affected dwellings,” adds Pascal Laporte, urban planning assistant in Plerain (Côtes-d’Armor), also noting the problem of “depreciation of property” at risk.
