California Code, Public Resources Code - PRC § 5629

(a) Sixty percent of the moneys shall be allocated to large cities which constitute heavily urbanized areas in the proportion that the population of the recipient bears to the population of all cities and recreation and park districts in heavily urbanized areas throughout the state.

(b) Forty percent of the moneys shall be allocated to large counties and regional park districts which constitute heavily urbanized areas in the proportion that the total population of the recipient bears to the total population of all large counties and regional park districts which constitute heavily urbanized areas throughout the state. Recognizing that the boundaries of counties and regional park districts may overlap, only the population of the jurisdiction which will actually provide and administer the recreational service contemplated shall be counted in the area of overlapping jurisdiction.
