The discovery of oil transformed Avenal into a boomtown. In 1929, Standard Oil surveyed the current site of Avenal to build a town. Makeshift houses were hauled in from Taft to take the place of the tents. A water line was laid and later a sewer plant was installed, a post office replaced a cigar box in the general store, a fire department was organized and a community grew. Standard Oil Company built the residents a 600-seat theater and a hospital.
