Forum 15 leads the agenda for decentralization of power from the central government to the local authorities, by reforming the relations between the state and the cities, in line with global trends and legislation.

The goal of this reform is to enable municipalities to provide better and more diverse services to residents and visitors. Not only cities will benefit from this process; decentralization also contributes to growth and development the national level.

In addition, the reform intends to grant cities the authority to determine policy in key issues - local legislation, budgeting, fee collection, transportation, infrastructure, climate environment, and more. 

In February 2014, the first section of the reform was approved – the law of fiscally robust cities. According to the law, a city that is defined "fiscally robust" will be entitled to autonomous management of several matters, including control over annual and development budgets, ,urban initiatives, permit provision, and more. In March of 2014, the law recognized 24 municipalities as fiscally robust (cities, local, and regional authorities).  

To date, the law has recognized 36 cities as fiscally robust (14 of which are Forum 15 members: Ashdod, Ashkelon, Beer Sheva, Hertzelia, Hadera, Holon, Haifa, Kfar Saba, Petah Tikva, Rishon L'tzion, Ramat Gan, Ramat Hasharon, Ra'anana, and Tel Aviv-Yafo).

Over the years, Forum 15 initiated several legal reforms and amendments for decentralization of power to local government, including:  the law for enforcement of elective bicycles and scooters  2016, greater authority in managing education, certifying planning and building committees as independent committees (2014), environmental enforcement law (2008), certifying cities to approve urban renewal plans (2021), and more. Currently, the Forum is advocating decentralization in the field of planning and management of transportation in the metropolitan area by legally enabling the establishment of metropolitan transport authorities, and more.
