The Arroyo Seco Water Reuse Project is a joint project between the Cities of Pasadena and South Pasadena, with Pasadena being the lead agency. The project consists of two locations along the Arroyo Seco Channel that will address water quality issues and assist in complying with a state-mandated requirement to reduce the bacteria levels from tributaries that flow into the Los Angeles River.
Through sampling of the outlets to the channel in dry weather conditions, San Rafael Creek and the Arroyo Seco Channel are two segments that have been identified to consistently have bacteria levels above the allowable limits set by the Los Angeles Regional Water Quality Control Board for fresh waters designated for recreational use. This project will aid in reducing the bacteria load flowing into the Los Angeles River utilizing nature-based approaches to the best extent feasible.
Thanks to the support of Senator Anthony Portantino’s office, the Cities of Pasadena and South Pasadena received a $3.5 million grant from the State of California, Department of Parks and Recreation’s Urban Counties Per Capita Program, under a subprogram specifically designated for the Arroyo Seco. The Cities received additional funding through Los Angeles County’s Safe, Clean Water Program (Measure W) for $4.7 million. Together, these grants will fully fund the project through construction.
The Safe Clean Water Program provides local, dedicated funding to increase local water supply, improve water quality, and protect public health. For more information regarding Los Angeles County’s Safe Clean Water Program please go to https://safecleanwaterla.org/
