Spane Park is a city-owned park in Paramount and is a Tributary to LA River. The park is in a disadvantaged community and was identified as an optimal regional project location in the Lower Los Angeles River Watershed Management Program (LLAR WMP). The Project takes advantage of pending park rehabilitation to install a 3.5-acre-foot capacity regional stormwater capture and infiltration facility. Other project components include a bioswale along the north end of the park, an ephemeral stream, permeable pavements and bioretention areas within the parking lots and pathways, and native California landscaping in the picnic area.
The Project is connected to a managed water supply aquifer (Central Basin of the Coastal Plain, Los Angeles aquifer) and will augment groundwater supply. The project will also address total zinc as the primary pollutant and bacteria as the secondary pollutant.
A 7.8 cfs pump and filter system will provide final pollutant removal prior to discharge back into the storm drain channel during larger events, while smaller events are anticipated to infiltrate. As a subconsultant to Craft Water, Inc, Myriad Engineering Myriad Engineering provided the design for the pump station including piping, valving, wet well layout, valve vault layout and design, and design layout for a transition structure from force main to gravity flow. We performed the hydraulic analysis for the pipe and pump sizing. We prepared the technical specifications using Master Format. We prepared the engineers’ construction estimate based on manufacturer costs and recent bids.
