Outstanding Water Project

Second Lower Feeder PCCP Rehabilitation - Reach 1 and 4

Metropolitan Water District of Southern California

System reliability is a core component of the Metropolitan Water District of Southern California’s (Metropolitan) mission, and the agency has embraced a proactive, systematic program for the rehabilitation of its large-diameter prestressed concrete cylinder pipelines (PCCP). The $2.4 billion program focuses on the PCCP portions of five existing feeders in Metropolitan’s service area. Basic program goals are to reduce the risk of unplanned outages, perform the work in a cost-effective manner, minimize impacts to member agency deliveries, and take advantage of opportunities to improve system flexibility and reliability. By objectively ranking and prioritizing PCCP reaches requiring rehabilitation, Metropolitan has developed a strategy to meet these goals.

Maintaining water deliveries to service connections during construction influenced many of the decisions for shutdown durations and locations of temporary bulkheads. A comparison of rehabilitation alternatives determined that relining the feeder with an internal coiled steel pipe liner was the most cost-effective rehabilitation method, resulting in faster installation and reduced construction costs. Other effective strategies that were addressed during the detailed design included minimizing downtime for deliveries to member agencies, reducing impacts to traffic flow, sequencing construction and reach isolation, and coordinating public outreach with local agencies and neighbors. Implementation of the Second Lower Feeder PCCP Rehabilitation Reach 1 and Reach 4 construction contracts was a collaborative effort among Metropolitan, its member agencies, the design consultant, Black & Veatch; the contractors, J.F. Shea Construction and Kiewit Corporation; and the local agencies and communities. All stakeholder parties worked together with a solution-driven approach which resulted in a project that was deemed a success and garnered accolades from stakeholders including the local residents. An excerpt from a neighbor’s note of appreciation exemplifies the project achievement: "Without fail, this is one of the best work crews that has ever been in our neighborhood."

Outstanding Bridge Project

"Red Car" Multi-Use Bridge over Los Angeles River

City of Los Angeles,

Bureau of Engineering,

Bridge Improvement Division

In 1929, the Pacific Electric Railroad Company built a six-span bridge over the Los Angeles River to carry the Red Car along its Los Angeles-Glendale Line. When Pacific Electric ceased operations in the early 1950's, the superstructure of this railroad bridge was demolished. The piers and abutments remained untouched in the channel. While a City’s interdepartmental task force contemplated potential implementation projects in the development of the Los Angeles River Revitalization Master Plan, the community of Atwater Village petitioned for the construction of a footbridge over the existing piers and abutments.

After much collaboration with community members, the Bureau of Engineering Bridge Improvement Division (BOE/BID) was commissioned to build a new bridge, the "Red Car" Multi-Use Bridge, as part of the Glendale-Hyperion Bridges retrofit and rehabilitation project.

During the construction of seismic retrofit and widening of the main bridges on Glendale-Hyperion corridor, the complicated traffic detour would demand frequent closure of traffic lanes and sidewalks. The environmental document identified the new bridge, located about 100 feet downstream from the main bridges, to be used as mitigation – an alternative route for safe pedestrian passage through the construction zone.

From the onset of the pedestrian bridge development, the community wanted the design of the new bridge to express the ‘elegance of simpleness’ as reclamation of its community identity. BOE/BID decided on a simple, yet aesthetic, prefabricated steel truss as the structural type. The 430-ft long, 14-ft clear width, three-span truss is supported by two retrofitted Red Car piers and abutments. A meandering pathway leads from the northerly touchdown of the new bridge to join the sidewalk of northbound Glendale Boulevard.

A strip of LED lights contained in handrails on each side of the walkway lights the walking surface at night. A simple 6" deep steel element runs the length of the bridge under the lighting and is painted red in memory of the Red Car traveling over the River along the same alignment more than 70 years ago.

The "Red Car" Bridge is located in the center of the most scenic stretch of the Los Angeles River. The simple truss structure is intentionally selected to optimize views of the revitalized Los Angeles River and the surrounding context by minimizing the side enclosures, allowing increased opportunities for photography and observation. The location of the bridge generously offers a unique panoramic view of the magnificent monumental Glendale-Hyperion Bridges 100 feet in front of it, with the hillside of Griffith Park as its natural backdrop.

Project design partners included Psomas and Gruen Associates. The construction contractor was Reyes Construction.

Outstanding Energy Project

AES Huntington Beach Energy Project and Alamitos Energy Center

AES Corporation

AES Corporation and Kiewit Power Constructors have gone above and beyond to help meet California’s clean energy goals by replacing AES’ older, 1950’s-era Power Generating units with cleaner, more efficient power plants in Long Beach and Huntington Beach. The AES Huntington Beach Energy Project (HBEP) and Alamitos Energy Center (AEC) are each highly efficient, combined-cycle gas turbine (CCGT) plants in 2x1 configuration which eliminate the use of ocean water for cooling purposes, reduce fresh water use by 70%, and cut emission rates by approximately 50% due to their fast start-up and rapid response capabilities. The deep foundations across both sites consisted of over 15,000 auger-cast-in-place piles and 175 underground shear panels to improve site soil conditions and meet seismic requirements. AES leveraged the near-identical footprint of the plants to complete the projects ahead of schedule, under cost, and with over 3.5MM Man Hours without a lost time injury by seamlessly moving lessons learned and best practices back and forth between the design and construction of each plant. The project’s success can be attributed to the unique and innovative approach to the design and construction, which was developed and executed by one highly-talented and safety-minded team across two separate sites. This approach increased collaboration amongst all groups from project development, design, and construction, to commissioning and operations. Both AES and Kiewit were composed of individuals with a wide range of experience. Experienced leaders effectively guided and developed less experienced teammates throughout the project, creating a collaborative, successful team. The Huntington Beach Energy Project (HBEP) and Alamitos Energy Center (AEC) will support the region's energy needs for 20+ years.

Outstanding Water / Wastewater Treatment Project

Regional Recycled Water Advanced Purification Center

Metropolitan Water District of Southern California

The Regional Recycled Water Advanced Purification Center is a 500,000 gallon-per-day demonstration facility designed to test an innovative advanced water treatment process train for potable reuse. The project is a partnership between The Metropolitan Water District of Southern California and the Sanitation Districts of Los Angeles County (Sanitation Districts). It will demonstrate an effective purification process for the Regional Recycled Water Program, a water reuse effort that could eventually produce up to 150 million gallons of purified water and a new reliable water supply for Southern California.

The Regional Recycled Water Advanced Purification Center began operations in October 2019 and is located at the Sanitation Districts’ Joint Water Pollution Control Plant (JWPCP) in Carson. The facility purifies treated wastewater from the JWPCP using an innovative three-step purification process consisting of membrane bioreactors , reverse osmosis and an ultraviolet light/advanced oxidation process. Key goals of the demonstration facility include testing this innovative purification process, ensuring it produces water safe for potable reuse, and obtaining regulatory approval of the process.

Metropolitan and the Sanitation Districts are working with the State Water Resources Control Board’s Division of Drinking Water and the Los Angeles and Orange County Regional Water Quality Control Boards for regulatory approval. Once water quality testing demonstrates that the resulting purified water meets all requirements for replenishing groundwater basins, the process would be approved by regulators and may be used in water reuse projects throughout California.

The Regional Recycled Water Advanced Purification Center allows Metropolitan and the Sanitation Districts to optimize operations, identify costs, gather operational data, and develop design parameters needed for a future full-scale facility. Furthermore, the facility is used to showcase the project to the public and gain support for this potential new source of water for Southern California.

Outstanding Community Improvement Project

Safe Routes to School: Little Street Demonstration Project

Los Angeles Department of Transportation

Safe Routes to School (SRTS) brings safety improvements to the streets of school neighborhoods, and safety education programs into school communities, partnering Los Angeles Department of Transportation's (LADOT) Vision Zero and City of Los Angeles Green New Deal milestones.

The 2019 SRTS Little Street Demonstration (Pop-Up) project at Esperanza Elementary School in Westlake brought together visionary engineering and educational programs to showcase the program’s mission to be agile and innovative. Engineering improvements trialed during the temporary transformation reflected the program’s community based approach to developing improvement recommendations – which began in Spring of 2017 with a community Walking Safety Assessment to identify local transportation challenges and guide the development of the school’s customized SRTS plan. Over the same three years, SRTS supported programs including annual Walk to School Days, the Student Travel Talley Project, monthly safety campaigns, and a Student Safety Valet to facilitate safety during drop-off/pick-up times.

In Los Angeles, SRTS has been driven by the passion of Margot Ocañas for student safety, innovative approaches to implementation, and persistence for building lasting inter- and intra-agency relationships to institutionalize change for school communities for nearly a decade. The Little Street Demonstration project was not only successful due to the immediate impacts on the community, but also because it became a rallying point for the SRTS program, garnering attention from Council District 1, the Los Angeles Unified School District (LAUSD), and LADOT. This success is visible in by Councilmember Gil Cedillo’s proactive identification of funding for final design and construction of the Little Street projects, and two additional demonstration efforts (one pending roll out as COVID-19 pandemic guidelines are loosened), and improved collaboration with LAUSD to formalize SRTS relationships.

Project partners included KOA Corporation and Nelson/Nygaard Consulting Associates.

Outstanding Historical Renovation Project

South Park Historic East Area

City of Los Angeles,

Department of Recreation and Parks

Since it was built in 1899, South Park has provided 18 acres of recreation and green space to the residents of South Los Angeles. At that time, new housing subdivisions were quickly replacing the walnut and orange groves that were common in that part of the City. The Parks Department began transforming it into a well-cultivated public garden with colorful flower beds and multiple species of trees. The community embraced the park, and began enjoying concerts at the bandshell, picnicking under the shade trees and taking flower-scented strolls. South Park became an especially popular place for casual games; card players filled the park's tables, while horseshoe pitchers took to the lawns. The main attraction was the dramatic “Palm Walkway” which was lined with a double row of majestic palm trees.

Over time, other improvements were added: a new Recreation Center and pool were built in the 1950’s by well-known Los Angeles Architect Paul Williams, and a new Gymnasium was added later in the 1980’s. Unfortunately, over time the historic walkways faded away, and the park lost much of its original vibrancy and appeal. In 2014, Councilman Curren Price Jr. and the Department of Recreation and Parks engaged the Bureau of Engineering’s Architectural Division to develop a new Master Plan for the revival of South Park, with the goal of recapturing its historic feel and cultural importance to the local community while serving the needs of today’s residents.

The current phase of the renovation of South Park covers the entire eastern portion of the park from the recreation center and pool building to Avalon Street. The highlight of this phase is the restoration of the iconic Palm Walkway, which has been reborn as the social backbone of the park with a new central walkway connecting picnic tables, benches & game tables where people can congregate and socialize. Historically-inspired light fixtures and colorful planting beds with decorative steel edging complete the scene. In addition, the community will also enjoy: new walkways throughout the park which have been carefully aligned to re-create the historic layout, a perimeter fitness path with outdoor exercise equipment groupings, relocated basketball courts with sports lighting, a synthetic turf play area, renovated bandshell viewing area, a new playground, new decorative pool fencing, picnic areas with barbecues and new site security lighting throughout the rest of the eastern park area. A total of 300 new trees have been planted to restore and enhance the shade canopy of the park for the next generation. The renovated eastern park area has proven to be a great step forward for South Park and will provide a strong foundation for its continuing role in this community."

Outstanding Small Project

Walnut Storm Water Capture and Groundwater Replenishment Basin

City of Torrance

In the 1950s, stormwater runoff from new housing developments in Torrance was routed to various sinks, where it would slowly seep into the soil, removing harmful pollutants and recharging the groundwater aquifer used as a drinking water supply. Following storm drain improvements in the 1970s, runoff was rerouted to Machado Lake, a 40-acre freshwater reservoir in Los Angeles, and dry basins were left behind. Currently there are impairments to Machado Lake’s designated beneficial uses caused by pollutants in stormwater runoff.

Located in a residential neighborhood in southeast Torrance, Walnut Basin is two acres and has the capacity to store approximately 23 acre-feet of water. The project called for the installation of a diversion structure, sized to take dry-weather and stormwater runoff from storms up to the 85th percentile storm event, while allowing runoff from larger events to continue down the storm drain unimpeded. Runoff is routed to a hydrodynamic separator pre-treatment unit, where debris and medium-to-large grain sediments are removed. After passing through the unit, runoff enters a 48-inch reinforced concrete pipe, which was jacked into place in a narrow easement between two houses, that conveys water to Walnut Basin. Riprap was installed at the Basin entrance to reduce runoff velocity and prevent erosion. The project recharges 44 acre-feet of runoff per year, providing water for 88 families. Implementation of this project accomplishes most of the required reduction from the critical baseline load for most pollutants, including nutrients, pesticides, polychlorinated biphenyls, bacteria, and lead. Future developments will include a Basin Habitat Restoration Plan to remove non-native flora and install drought-resistant California Native plants, based on the completed phenology study.

The cost of the first phase was approximately $900,000, including construction and design. The project was 50% funded with residual state grant funding from Proposition 13 (2000) and Proposition 40 (2002).

Project patners included CWE, SRD Engineering, Terracon Consultants, Inc., Murakawa Communications, and C-Below.
