#2026-318Extension of the Châtenay Hill protected site in Fontenay-en-Parisis, Val-d'Oise
AI-generated summary for informational purposes only. Not legal advice. See the original source for the authoritative text.
This decree expands the protected landscape area of Châtenay Hill in Fontenay-en-Parisis, in France’s Val-d'Oise department. It adds about 343 hectares to the classified site, which means land use, development, and changes to the landscape in the listed parcels will face stronger protection rules. It affects local authorities, landowners, developers, associations, and anyone planning work on the covered parcels. The earlier 1972 listing is partly отменed for the newly classified area, and the decree takes effect the day after publication, so businesses and property owners should check the parcel maps before starting any project.

Obligations
What this law requires
The prefect of Val-d'Oise must be notified of the decree extending the classified site of the butte de Châtenay in Fontenay-en-Parisis.
Any land use, development, or landscape-altering work on the parcels and non-cadastral spaces included in the extended classified site of the butte de Châtenay in Fontenay-en-Parisis must be treated as subject to the site-classification protection regime under articles L. 341-1 et seq. of the French Environment Code.
Anyone undertaking works or changes within the extended classified site of the butte de Châtenay on the territory of Fontenay-en-Parisis must take the site-classification protections into account for the affected parcels and spaces covered by the decree.
Before starting projects, concerned parties must verify whether their property lies within the classified parcels listed in the decree’s cadastral annexes, including partially classified parcels and specified non-cadastral spaces.
For land located in the designated extension area, the applicable protected-site boundary is the parcel list, partial-parcel delimitations, non-cadastral spaces, map at 1/25,000, and cadastral plans annexed to the decree; compliance decisions must be based on those annexed delimitations.
