California Code, Education Code - EDC § 16705

The board by the adoption of rules shall give priority in allocating funds to urban districts to those districts where the children will benefit most from schoolhouse facilities. This priority shall be based upon the age of existing buildings and the acuteness of overcrowding at the school or schools where the construction or reconstruction will occur, the density of population in the attendance areas affected, or any other factors that will insure that the greatest need will be served.
