He originated a bank, the "Banco de San Carlos" - which is the precursor of today's Bank of Spain, a company to trade with the South American colonies and with Asia through the Philippine Islands - the Real Compañia de Filipinas, and an agricultural and hydraulic project known as the "Canal de Cabarrus" which is the origin of today's Canal de Isabel II, supplying the water to the city of Madrid, in the northeast of the Madrid Community - in the course of the Jarama and within the municipal boundaries of the towns of Torrelaguna, Patones, Torremocha del Jarama, Uceda and Caraquiz. He was also involved in at least two other projects involved in the opening of navegable waterways which were never completed. One was the Canal del Guadarrama which was supposed to open a navegable waterway from Madrid to the Ocean linking several river basins from the Guadarrama River up to the Guadalquivir River and from there to the sea (several ruins of these canals are still visible in the Guadarrama River basin area). The other project involved the widening of the LLobregat River in the province of Barcelona in Catalonia in order to open up the Llobregat River valley to shipping and thus give impulse to the future industrial region of Catalonia with all the textile and mining projects of the region.
