How did Augustus reorganize Rome into wards and precincts?

To address the administration of the city, Augustus moved away from the amateur systems of the Roman Republic by establishing more professional and permanent institutions.

In 7 BCE, he reorganized the city of Rome into 14 regiones (wards). These wards were further subdivided into vici (precincts). Each of these precincts was assigned officials who were responsible for carrying out both administrative and religious functions within their respective areas.1

This reorganization was part of a broader effort to improve urban management, which also included the creation of a professional fire brigade known as the vigiles and the establishment of cohorts to maintain order in the city's streets under the command of the urban prefect.1
