The total cost, or any portion of the cost that is assessable against all the real property within any district or area benefited by the local improvement, may be apportioned according to the benefits to accrue to each lot or tract, as determined by the governing body. In determining benefits to a district or area, the governing body shall determine the amount in which each lot or tract located within the district or area will be benefited by the construction of the improvement, and shall assess against each lot or tract that amount, not exceeding its special benefit, as is necessary to pay its just portion of the total cost of the work to be assessed.
