Ed. Code, § 16056

When a unified district which is otherwise qualified for an apportionment under this chapter applies for an apportionment and the area of adequate school construction existing in any one of the component elementary districts included in the unified district is of such an amount that the district is prevented, by Sections 16044 to 16055 inclusive, from receiving an apportionment, the maximum area of school construction for each unit of attendance, for elementary school construction prescribed by such sections, may be computed separately for each component elementary district without regard to the area of adequate school construction existing in the other component districts, and apportionments made to the unified district on the basis of such separate computations. On request of the governing board of the unified district the State Superintendent of Public Instruction shall make or cause to be made a survey of building needs in the district and the area computations for elementary school construction. He or she shall report his or her findings and recommendations to the board for consideration in connection with any application before the board from the unified school district.
