Hermosa Beach was part of the ten-mile ocean front of Ranco Sausal Redondo. In the early years Hermosa Beach was one of the rolling hills covered with fields of grain. In different seasons of the year heads of sheep grazed the land.
Long time residents claim that the climate was pleasant, being warmer and having less fog and sand was always blowing from the sand dunes. Early pioneers named the city of Hermosa meaning "beautiful".
In 1904 the pier was built. This original pier was constructed entirely of wood to the pilings and extended 500 feet into the ocean. In 1913 the pier was partly washed away and then torn down. A new one was built to replace the original pier. A newer pier was built from concrete and one thousand feed long and paved with asphalt.
The city now is located in the South Bay, one of the three beach cities. Hermosa Beach is bordered by Manhattan Beach to the north and Redondo Beach to the south and east. The city itself is about 15 blocks from east to west and 40 blocks from north to south with Pacific Coast Highway running down the middle.
