The Territorial Planning Commission of Castellón, in their session of March 31, 2015, approved the Puntual Modification No3 of Master Plan of Cortes de Arenoso (Spain) written by AUG-ARQUITECTOS, SLP. It is the most substantial modification suffered by the Plan in its fifteen years of existence. The plan had been also drafted by AUG-ARQUITECTOS, SLP in the past nineties and it has now been seen fit to introduce certain changes leading to a decrease of the developable land, reducing it to what is strictly necessary. At the same time the opportunity has been taken for a detailed ordering of all soil subjected to programming, as well as to enhance the graphic quality of cartography, now entirely elaborated on digital media and adapted to the current reality of the municipality.
