Title

Poche Beach Structure (Best Management Practice Water Treatment System)

Description

The CDFG is issuing an Agreement regarding the Stream or Lake Alteration to the project applicant, Sonia Nasser, representing the County of Orange. The applicant proposes to alter the streambed of Prima Deshecha Creek to accommodate the Poche Beach Modular Treatment System in order to reduce bacterial loading at Poche Beach. This will include collecting urban runoff from Prima Deshecha Creek near the ocean outlet, treating the water in a portable modular treatment system to remove bacteria, and releasing the water back onto Poche Beach. Approximately 700,000 gallons per day of dry-weather urban runoff will be collected using an inflatable rubber dam structure. Water will be diverted by the inflatable rubber dam into a wet well adjacent to the channel on railroad property between Pacific Coast Highway and the railroad tracks. There, the water will be treated, using ultraviolet disinfection to remove bacteria, and released at the beach outlet where it will flow along its original course to the ocean. The inflatable rubber dam will be deflated when rain is anticipated, and in the case of unexpected rainfall, the high water sensor will automatically deflate the rubber dam to prevent constriction of the drainage flow path.
