One purpose of the park is to reduce the environmental impact of the waste water and storm runoff leaving the drainage basin area. This is being accomplished by installing a series of water flow control structures ... and creating ponds that together slow down the flow of the water, catching silt and reducing the undercutting of the dirt walls that form the wash. The sides of the wash are being stabilized by installing native plants and large pieces of demolished construction debris. Some of the native plants ... help to purify the water by removing various pollutants as the slow moving water provides these plants with nourishment. This method of purification is also called natural water polishing. [Wikipedia]
