The grants from the investment aid fund provided for in article L. 1424-36-1 are distributed each year between the departmental and territorial fire and rescue services and the commune of Marseille on the basis of an amount established, in metropolitan departments, by defence and security zone and, in overseas departments, by department. This apportionment takes into account, as from 1 January 2005, the subsidy to be paid to the fire and rescue service of the departmental community of Mayotte, in accordance with the provisions of article L. 1711-4.
The amount of appropriations allocated to each defence and security zone is set on the basis of the population of the départements making up each zone, defined according to the procedures set out in article L. 3334-2, after taking into account, where applicable, a reserve intended to support operations of national interest.
For the Paris defence and security zone, only the population of the departments of Seine-et-Marne, Yvelines, Essonne and Val-d’Oise is taken into account.
