Green Stormwater Infrastructure (GSI) Hydrologic Modeling: Albion Riverside Park Project in Los Angeles, California
The Albion Riverside Park (Project) was constructed to prevent stormwater pollution runoff in the city of Los Angeles (City) rivers, lakes, and beaches. The stormwater facilities is owned and operated by LA Sanitation and Environment (LASAN) residing in a new park owned and maintained by City Department of Recreation and Parks (RAP). The 272-acre drainage area is predominantly residential and commercial land uses that drain to the site, and total project budget cost is $39.9 million including land acquisition and site remediation/clean up. Hydrologic modeling for this green stormwater infrastructure (GSI) project compares results from field data for water quality/quantity. This project improves the water quality of stormwater and dry-weather runoff entering the LA River to help meet city’s total maximum daily load (TMDL). TMDLs provide a useful framework for stormwater quality management and modeling in urban settings, as shown in this work. Treated pollutants of concern include: bacteria, heavy metals, trash, oil and grease, volatile organic compounds, zinc, and copper. The project components are as follows: flows up to 28 cfs peak flow for 0.9 inch (85th percentile) design storm; two hydrodynamic separator units; underground infiltration galleries [capacity equal to 1.7 million gallons (MG)]; potential annual volume 31 MG/Year (95 AFY) infiltrated; bioswale area (12,000 sq. ft.); parking lot permeable paving area (7,500 sq. ft.). Details of water quality and water supply, water quality monitoring, flow meters, and infiltration volumes will be reviewed. The GSI hydrologic modeling methods are demonstrated in Los Angeles, California.
