BACKGROUND

In 1965-1966, a flood control basin was built in Cypress. It was built where the Nature Park is now. The reason that the flood control basin was built here is because it is the lowest point in the area. Rather than leave the lot as an empty basin Cypress chose to make this area into a nature park so that visitors could observe and interact with nature.

The flood control basin can collect many thousands of gallons of water. It collects both rainfall and water run-off from the mountains and the streets. Every few years the basin is flooded to maximum capacity. In these years of heavy rainfall, if the basin were not here the entire southwest portion of the city would be flooded.

In the park, three emptying pipes bring water into the basin. In the southwest portion of the park, there is a pump station that pumps the water our of the park. The emptying pipes have small columns in front of them to block large objects from getting clogged up in front of the pipe. The pumphouse has a large grate in front of it that helps prevent trash from being pumped out of the park.

The pumphouse can pump up to 35,000 gallons of water per minute! The water from the basin is pumped into the Carbon Creek Channel. It's eventual destination is the Long Beach Harbor so it is very important that the water remain as clean as possible.

WHO BUILT THE NATURE PARK?

Cypress Nature Park was planted and built by many members of the Cypress community. For example, The Woman's Club of Cypress and the Junior Woman's Club of Cypress donated many of the tree specimens that are in the park. Boy Scout troops help clear the trails, provide tree identification markers and build stairs in the park. This spirit of volunteerism helped bring the Nature Park to life.
