The Municipal Urban Planning Plan (POUM) is the instrument of urban planning of the municipality that directs the development of the territory of Alella. The mapping of the Alella POUM consists of two blocks of maps of different scales in PDF format, called Information Plans and Regulatory Plans. In the Regulatory Plans we find: the Qualification of the current land, the current Uses in non-urban land, the Inventory of goods to be protected or cataloged and the Barcelona Metropolitan Territorial Plan (Open spaces system); and in the Regulatory Plans: the Land Regime, the General and Organic Structure, the Non-urbanizable Land, Planning Sectors and polygons (Open Space System), the Urban and Urbanizable Land Classification, the Urban Land Rating and finally , the Heritage Catalog, SNU Farmhouse Catalog, SNU Buildings Inventory and Rural Road Network.
