When the total amount of subsidies likely to be granted has been determined, the distribution of subsidies between local authorities and groupings in the same département is established on the basis of maximum subsidy rates applicable as follows:
1° A rate of 80% when the amount of damage suffered is greater than 50% of their total budget;
2° A rate of 40% when the amount of damage suffered is between 10% and 50% of their total budget;
3° A rate of 30% when the amount of damage suffered is less than 10% of the total budget ;
