The Code de l' urbanism defines four types of zones regulated in the local plan of #x27; urbanism (R.123-5 to 8): urban areas (U), urban areas (AU), agricultural areas (A) and natural and forest areas (N). These areas are delimited on one or more graphic documents. A settlement is attached to each zone. The regulation may lay down different rules, depending on whether the purpose of the constructions concerns the habitation, l' hotel accommodation, offices, commerce, l' handicrafts, l' industry, l' agricultural or forestry operations or the function of #x27; warehouse. These categories are limited (Art. R.123-9).
__Origin__
The boundaries of a zone are represented on the graphical documents of the PLU or POS. They generally correspond to the boundaries of n°#x27; an aggregate of cadastral plots. The geometry of cadastral plots is a data derived from the cadastral geographical reference chosen at the time of the; elaboration of the document d' urbanism.
This cadastral geographical repository can be either the Parcellar BD provided by the Ø;IGN, or the computerised cadastral plan (CCP) provided by the DGI.
