Greener, less Parisian: Valérie Pécresse presents her development plan for Ile-de-France

"Region of 20 minutes", "rebalancing", "reindustrialization": the president (LR) of Ile-de-France Valérie Pécresse presented Monday April 3 the future development plan of the region, which she wants to adapt to global warming and less centered on Paris.

The Sdrif (Master Plan for the Ile-de-France region) plans long-term land use planning and must be respected by local elected officials in their urban plans. The previous one was from 2013.

The document, a "V0" according to the vice-president in charge of urban planning, Jean-Philippe Dugoin-Clément, should be submitted for the first time to the regional council in the summer, then adopted in its final form in the summer of 2024. .

To center the region less on Paris, one of the axes of Valérie Pécresse's policy, the president has defined 27 "centralities", cities around which she intends to concentrate her efforts and which will have the right to urbanize more than the others.

"We are going to break this deadly logic of the metro-work-sleep", promised Valérie Pécresse, promising "a polycentric region, with economic development of great proximity and which puts the quality of life at the center of the project."

To connect them, some 656 kilometers of additional public transport are planned or already under construction.

"Some have spoken of a quarter-hour city but we could paraphrase by speaking of a 20-minute region", she added, borrowing from the concept of "quarter-hour city" promoted by the mayor of Paris. Anne Hidalgo.

The Sdrif will require new buildings to be thought of as reversible, i.e. adapted to a change in use (housing, offices, retail, etc.), and to integrate biosourced materials, such as wood, into their construction, more ecological.

The region, which will sanctuarize agricultural areas threatened by urbanization, has set itself the goal of reducing the rate of soil artificialization by 20% per decade.

Less than what the law imposes on other regions (50% per decade), before reaching zero net artificialisation in 2050.

Doing more, when Ile-de-France is already the densest region in France, would be "socially untenable", given the population growth and housing needs, justified Jean-Philippe Dugoin-Clément.

The region maintains its objective of producing 70.000 new dwellings per year, but these may be the result of transformations or rehabilitations rather than new constructions.

Part of the land in the region, 28.000 hectares, will be reserved for "reindustrialization", including 600 for new sites.
