Stormwater Engineering Projects

Picture of Santa Anita Spreading Grounds


The project consists of numerous improvements to enhance recharge operations at the Santa Anita Spreading Grounds, including modifying the spreading grounds intake junction box, regrading the intake canal, replacing a portion of the headworks pipeline, modifying the westside canal structures, constructing structures to reduce erosion in the eastside canal and installing a low-flow gate, enlarging the spreading basins, replacing interbasin structures, and constructing an overflow structure. The purpose of the project is to improve the facility's ability to conserve higher turbidity flows and to increase the operational efficiency of the facility by modernizing operations.

This project is partially funded by a State Proposition 1E grant as well as funds from the City of Arcadia, City of Sierra Madre, the Raymond Basin Management Board, and the Los Angeles County Flood Control District.


The project was advertised for construction in December 2016 and awarded in March 2016 to C.W. Crosser Construction. Construction began in July 2016 and is anticipated to be completed May 2017.
