Central Business Districts
Santiago City has the widest and most well-kept business district in Cagayan Valley. Its public market of more than 6 hectares is one of the biggest distribution centers in the Philippines. In terms of cleared checks at the clearinghouse, the volume of transactions in the city is among the top five in the country. At present, there are about 5,100 registered business establishments in the city while new business permits have been issued to investors from as far as Manila. The city has 35 banks, the most-numbered in the region. The Santiago City Government has installed more than 50 closed circuit television (CCTV) cameras in strategic areas to monitor public safety and traffic flow in the city. Also, the installations of sodium-vapor streetlights were made to illuminate the roads and prevent accidents (e.g. vehicular accidents) and help lessen the crime rate or the proliferation of criminals especially at night.
