Broadmoor is low-lying ground in New Orleans, and was only substantially developed beginning in the early 20th century after improved drainage was initiated (see: Drainage in New Orleans). Before being developed, the area was a large marsh and was a fishing spot for Uptowners. Early construction were mostly high raised houses for fear of repeats of historic floods, but after decades with little problem more low lying residential structures were built in Broadmoor. The first area drainage canals were built in 1885. In 1903 a pumping station at Broad Street and Washington within the Broadmoor boundaries opened in 1903. In 1915, pumps more powerful than previous ones were established at that pumping station. After 1915, smaller groups of people began settling the area.
