Simple download service (Atom) of the dataset: Concerted development zones (ZAC) in the department of Seine-Saint-Denis

Implemented from 1970 onwards, “concerted development areas are those areas within which a public authority or a public establishment whose purpose is to do so decides to intervene in order to carry out or cause to be carried out the development and equipment of the land, in particular those which that community or establishment has acquired or will acquire with a view to transferring or subsequently granting it to public or private users”. Public facilities under the ZAC can be of very different types, such as supply to the drinking water and sanitation network, roads, schools, homes, etc. The urban planning project of the ZAC, established around a specific construction programme and public facilities (housing, activities, equipment) could either consist of a specific planning document, the area planning plan (PAZ), or could be the application of the town’s urban planning regulation, the land use plan (POS). Since the Law on Solidarity and Urban Renewal (SRU Act), the urban planning rules for the new ZACs are now included in the Local Planning Plan (LDP) in order to better integrate them into the surrounding urbanisation. However, the PAZs approved before the coming into force of the SRU Act continue to apply and may be amended to adapt them to changing needs. The concerted development area is an alternative to that of the subdivision: this is normally a private initiative, whereas the CAZ requires the will of a public community.
