Final Liability Amount. The Final Liability Amount consists of the added amounts for each violation, with any allowed adjustments, provided the amount is within minimum and maximum liability amounts. The Combined Total Base Liability Amount was added to the investigation and enforcement costs accrued by the Los Angeles Water Board Prosecution Team. The Final Liability Amount is $7,382,447, which is within the minimum and maximum liability amounts.11 11 As explained in Section II, paragraph 12 of the Stipulated Order, the administrative civil liability was reduced to $6,000,000 under Enforcement Policy, section VI.B. (Settlement Considerations) in consideration of hearing and/or litigation risk. CALAS PARK STORMWATER AND WATER QUALITY IMPROVEMENTS SUPPLEMENTAL ENVIRONMENTAL PROJECT WORKPLAN Calas Park Stormwater and Water Quality Improvements Supplemental Environmental Project (Calas Park SEP) Los Angeles County Sanitation Districts (public) Project Manager: ▇▇▇▇ ▇▇▇▇▇▇▇▇▇, Supervising Engineer (▇▇▇) ▇▇▇-▇▇▇▇ extension 2811 City of ▇▇▇▇▇▇ (public) Project Manager: ▇▇▇▇▇▇ ▇▇▇, PE, Stormwater Engineer (▇▇▇) ▇▇▇-▇▇▇▇ extension 3523 ▇▇▇▇▇▇ is a Licensed Civil Engineer (CA) with 9 years of experience in both public and private stormwater infrastructure projects, water quality analysis, and infrastructure maintenance. He received his B.S. in Civil Engineering with an emphasis on Environmental Hydrology from the University of California, Irvine in 2014. He also holds a B.S. in Biology from the University of California, San Diego. At the City of ▇▇▇▇▇▇, ▇▇▇▇▇▇ works as the Stormwater Engineer managing and developing green infrastructure projects and managing MS4 permit compliance. Throughout his career, ▇▇▇▇▇▇ has worked on a variety of projects related to stormwater, encompassing roles such as conceptual design, planning, grant funding, construction, post- construction review, maintenance, and water quality testing in both urban and natural infrastructure. His experience in both private and public enterprises provide a solid foundation to guide the effective development and management of stormwater projects. ▇▇▇▇▇▇’s experience with multi-benefit stormwater infrastructure is extensive. He has worked on several public stormwater projects, notably: South Los Angeles Wetlands Park, Mar Vista Recreation Park BMP, Echo Park Lake Rehabilitation, and the City of ▇▇▇▇▇▇’▇ Carriage Crest Park Stormwater facility. He also has experience in designing and reviewing stormwater treatment and capture devices for private developments. With these projects, he has focused on providing maximum benefit to the general public in the form of improved recreation, climate resilience, and clean water. The Calas Park SEP will be located in Calas Park, which is on E 220th St between ▇▇▇▇▇▇ St and S ▇▇▇▇▇ St in the City of ▇▇▇▇▇▇ in Los Angeles County. This SEP is located in the ▇▇▇▇▇▇▇▇▇ Channel watershed. This voluntary project is expected to capture, pretreat and infiltrate 2.8 acre-ft of stormwater produced in the drainage area (based on the 85th percentile, 24-hour storm). See Attachment A for drainage map. The proposed project will capture runoff in an underground vault where the water will infiltrate. The project features will involve underground storage vaults, bioswales, rain gardens, infiltration galleries, and other elements that will capture, pretreat, and infiltrate stormwater onsite. Based on the size of an 85th percentile storm, which occurs on average five times per year, a preliminary estimate of the volume that will be captured and conserved is 2.8 acre-ft per event and 13.8 acre-ft on an annual basis. Stormwater runoff will be diverted from a storm drain in E 220th Street at South ▇▇▇▇▇ Street (northeast of the park) and from storm drain inlets in ▇▇▇▇▇▇ Street at 223rd Street (southwest of the park). The captured stormwater runoff will flow through a pre-treatment unit (hydrodynamic separator) via a proposed conveyance system before entering an underground storage vault, which will facilitate infiltration into the underlying groundwater. Initial review of available information for groundwater depth, soil type, and groundwater contamination reveals infiltration is possible, and a detailed geotechnical investigation will be conducted as part of the project to determine infiltration rates across the site. In addition, the project proposes a passive irrigation system that will be filled with stormwater for irrigation use of the Calas Park field(s), thereby offsetting the current reliance on potable water for irrigation.
