Title

Calas Park Stormwater and Water Quality Improvements Supplemental Environmental Project

Description

The project entails constructing and operating a stormwater capture and treatment facility within the northern portion of the City of Carson's Calas Park, as well as other ancillary park improvements. The stormwater capture and treatment facility would intercept stormwater and dry-weather flow from three existing underground storm drains and convey flows into an underground storage reservoir to be installed beneath the park's sports fields. A pump would be installed to return treated stormwater back to the existing catch basin. A vegetated bioswale would be installed north of the park’s tennis courts. Once the proposed facility is installed, the existing sports fields would be replaced. The existing field fence along East 220th Street would be replaced with a 12-foot fence and ballfield turf removed for construction of the project would be replaced with city-provided soil and sod specifications. The project is the result of the 2023 Settlement Agreement and Stipulation Order No. R4-2023-0088 between the Los Angeles County Sanitation Districts and the Los Angeles Regional Water Quality Control Board. The Sanitation Districts have agreed to provide funding for the City to implement the project workplan in response to violations occurring from discharge of untreated wastewater into the Dominguez Channel.
