Ballston Wetland Park Arlington County Department of Environmental Services
Project Location: Arlington, Virginia Project Start Date: 1 December 2021 Project Completion: 18 August 2023
Project Team: Arlington County, RKK Civil Engineering (design), Environmental Quality Resources (construction), Wetland Studies and Solutions (construction management), StormRax (trash control device), WATERGOAT (floating trash control barrier), Virginia Department of Environmental Quality (State and Local Assistance Fund grant) Project Summary: The Ballston Pond was originally designed and con- structed as a stormwater facility to collect and slow runoff from Interstate 66 when the highway was built, but, over the years, the pond has filled up with sediments deposited by stormwater runoff. Retrofitting the Ballston Wetland Park was a high-priority project in Arlington County’s Stormwa- ter Management Program, and they were able to seek community input through a stakeholder advisory committee as well as with several com- munity meetings to provide input to the design process. Additionally, retrofitting the pond to provide higher quality water treatment helps the county comply with the municipal separate storm sewer system permit and contributes to restoring the Chesapeake Bay. Impact: Cleared of sediment and now capable of taking excess rainwa- ter from 450 surrounding acres, the retrofitted wetland system improves stormwater flow and filtering–plus capturing trash–while also serving as a wildlife refuge and pastoral commons within the Ballston “urban village” setting. The park expands Arlington County’s ability to meet Chesapeake Bay Watershed regulations while cultivating native plants and providing new boardwalk areas and fresh interpretive designs. Community input from the engagement process helped to guide the selection of new fea- tures at the wetland park such as trash collection devices, an expanded viewing platform, interpretive signs, and wildlife habitat.

Day County Highway 1 Bridge Replacement IMEG Project Location: Day County, South Dakota Project Team: Project Team: Project Manager – IMEG, Steven Myer, Steven; Hydraulics – IMEG, Trent Baumeister; Designer – IMEG, Colin Kelley; Designer – IMEG, Joshua Prather; Construction Project Engi- neer – IMEG, Troy Nelson; Owner – Day County, Ben Braaten; Sisseton Wahpeton Oyate Indian Tribe, Cliff Eberhardtk; Journey Group (dba SFC Civil Constructors), Kyle Brockmueller; South Dakota Department of Transportation, Wade Dahl Project Start Date: 15 August 2017 Project Completion: 18 April 2023 Project Summary: The 74-foot single-span steel stringer bridge on Day County Highway 1 over Blue Dog Lake had faced flooding for several years, as the road is only two feet higher in elevation than the outlet of the lake. IMEG initially conducted a hydraulic analysis, and a single-span concrete girder bridge was selected as the replacement structure, but, by the time the design was initiated, the site sustained back-to-back 100-year storm events that caused the lake to rise considerably–making the exist- ing structure selection unusable. IMEG reanalyzed the hydraulics and a four-cell cast-in-place concrete box culvert was selected as the structure. Construction was completed over the winter season, from November to April, which created challenges with protecting the concrete during the curing process in extreme cold temperatures. Impact: The road serves as the primary paved connection between City of Waubay and the Enemy Swim Day School District as well as several residences and small businesses along Blue Dog Lake and Enemy Swim Lake. Because the bridge was prone to flooding prior to the construction of the box culvert, residents were faced with long detours around the lake to reach their destinations. The new box culvert significantly improves travel times and accessibility for the community, and is designed so that the road grade can be raised an additional four feet to help alleviate flood - ing issues going forward.

Velasco Terminal Berth 8 McCarthy Building Companies, Inc.
Project Location: Freeport, Texas Project Start Date: 6 January 2020 Project Completion: 28 April 2023 Project Team: Port Freeport, McCarthy Building Companies, Inc., Moffatt & Nichol Project Summary: Port Freeport, sixty miles from downtown Houston, is one of the fastest-growing ports in Texas and is undertaking expansion to handle an increased flow of goods. In 2020, Port Freeport hired McCa - rthy Building Companies as the Prime General Contractor to execute the Velasco Terminal Berth 8 expansion–a $129 million project which later grew to $140 million with the addition of a Roll-on Roll-off dock adjacent to Berth 8. McCarthy first had to construct this project’s bulkhead portion, which was a critical component of the Freeport protection levee system and vital for flood control purposes. This infrastructure expansion doubles the capacity of Port Freeport’s import and export operations and allows simultaneous ship-to-shore operations of multiple post-Panamax ships. Impact: Because the Velasco Terminal Berth 8 project site was located on the water, there were many environmental and spill prevention plans in place to prevent leaks from equipment, as well as debris from getting into the water. One interesting aspect of the project modified to allow long- term benefits to the area was the modification of the under-dock slope protection system. Initially, the plan was to place loose rip-rap rock on the slope to prevent material sloughing. After consideration from the project team, it was decided to utilize a fabric formed concrete mattress. This mattress, in place of the rip-rap rock, allows for more connected slope protection and prevents loose rocks from sliding into the dredge template. By doing this, dredging maintenance will be more efficient due to reduced debris in the template in the long term.

Buescher State Park Dam Halff Project Location: Smithville, Texas Project Start Date: 2 August 2019 Project Completion: 18 August 2023 Project Team: Halff
Project Summary: Remnants from Hurricane Harvey in 2017 hovered over Central Texas for several days, creating flooding throughout the region that damaged structures such as the historic Buescher State Park Dam. The dam’s structural integrity was threatened as several feet of ma- terial eroded away during the rain event, and the Texas Parks and Wildlife Department (TPWD) needed to find an immediate solution that would preserve the historic structure and protect a critical economic resource. After the emergency repair and understanding the importance of a more permanent solution, TPWD again contracted Halff to implement detailed construction plans, specifications, and cost estimates for rehabilitating the dam to comply with current regulations, which included improvements to the dam’s embankment and principal spillway. Impact: By finding a permanent solution for the dam, TPWD has been able to reopen its recreation program, which will ultimately help lift the local economies of Smithville and Bastrop. Halff also developed an inno- vative approach to reduce potential impacts to endangered species, partic- ularly the Houston toad, which included measures like taking a traditional silt fence and repurposing it to develop toad exclusion fencing. Design enhancements for the new structure included installing a sharp-crested, straight drop principal spillway, training/retraining walls, grading, native stone rock riprap and stream enhancements.

Oakland Zoo Emergency Culvert Replacement ENGEO Incorporated
Project Location: Oakland, California Project Start Date: 1 January 2023 Project Completion: 3 February 2023
Project Team: Jeff Fippin, GE (Principal) Jon Buck, PE Sean Cleary, PE Project Summary: On December 31st, 2022, after several days of rain from an atmospheric river, the 72-inch culvert passing underneath the entrance road to the Oakland Zoo suddenly and unexpectedly collapsed during extremely heavy flows–washing away a 25-foot-wide section of the road and exposing utilities. As an on-call consultant, ENGEO quickly assisted City of Oakland staff and their on-call contractor (McGuire and Hester) in assessing the conditions, stabilizing the area of the failure, monitoring the conditions during ongoing storm events, and obtaining emergency permits from Federal and State agencies to replace the culvert and repair the road. ENGEO, the contractor, and the City of Oakland worked collaboratively to efficiently develop repair recommendations, prepare construction plans and specifications, and perform construction quality control services for the project that was completed in approxi - mately 3.5 weeks, allowing the Zoo to reopen in just 35 days. Impact: Opened in 1922, the Oakland Zoo is a significant cultural and historical feature in the City of Oakland and is heavily involved in the local community, offering education programs to schools, supporting non-profits, and offering free and discounted admission to disadvantaged families and children. The shutdown of the Zoo had serious financial im - plications–totalling an estimated $500,000 lost in weekly revenue during the shutdown–so the project’s timing was crucial. The creek channel was also repaired, which eliminated the risk of further environmental damage to the creek and Zoo property.

Alpha Testing utilized two on-site laboratories and up to 15 full-time field and laboratory personnel to serve the Bois d’Arc lake project that will span 16,641 acres. Impact: Bois d’Arc Lake will be a tourist and residential destination for numerous outdoor recreational outdoor activities including fishing, boat - ing, and time spent by the water while also serving as a critical water source as demand grows for a rapidly expanding population of North Texans. Bois d’Arc Lake will provide water services for nearly 80 com- munities just outside of the Dallas-Fort Worth Metroplex–an area that is expected to double in population by 2050 according to the NTMWD. The Leonard Water Treatment Plant (WTP) will treat water from Bois d’Arc Lake to meet federal and state standards, which is necessary when deliv- ering water to the northern portion of the NTMWD’s service area.

72-inch Water Line from Emancipation to Tuam Lockwood, Andrews & Newnam, Inc. (LAN) Project Location: Houston, Texas Project Start Date: 3 February 2020 Project Completion: 21 March 2023 Project Team: Houston Public Works, LAN, Harper Brothers Construc- tion Accreditations and Awards: Texas Chapter American Public Works As- sociation (APWA) Project of the Year – Environments Project Summary: In response to a mandate issued by the Harris-Galves- ton Subsidence District (HGSD) to increase usage of surface water and decrease groundwater use, the City of Houston created the Surface Water Transmission Program (SWTP) in 1985, and, for almost forty years, LAN has served as Program Manager for the SWTP that has constructed over 300 miles of surface water transmission mains up to 108-inches in diame- ter. The SWTP 72-inch Water Line from Emancipation to Tuam is the first segment in a series of four that will serve as a refill line to the Southwest Pump Station, which supplies potable drinking water to one third of the City’s 2.3 million residents. With a total of over 7,800 linear feet, the scope of work included full roadway reconstruction, drainage improve- ments, traffic signalization improvements, street lighting improvements, and sidewalk improvements Impact: The project alignment, which extended through a densely pop- ulated urban area beginning east of Downtown, was an example of the “complete streets” concept and how it can be achieved in a densely pop- ulated area. “Complete Streets” is an approach to planning, designing, building, and maintaining streets that enables safe access for the local community, which includes motorists, pedestrians, and cyclists. Our ap- proach was not only to reconstruct the street from right-of-way to right- of-way, we also provided upgrades to drainage and underground utilities to bring them up to current standards. Mobility was improved with new traffic signalization, street lighting, and wider sidewalks. Throughout the construction phase, priority was given to the needs and concerns of the local residents. The Contractor phased the project to minimize impact, and all concerns were addressed promptly by the team.

San Fernando Regional Park Infiltration Project CWE Project Location: San Fernando, California Project Start Date: 1 December 2018 Project Completion: 4 October 2023 Project Team: City of San Fernando, CWE, Ortiz Enterprises, Inc., C Below, Inc., Terracon Consultants, Inc., Linkture Corporation Project Summary: The City of San Fernando (City) is implementing the San Fernando Regional Park Infiltration Project (Project). The Project was identified in the Upper Los Angeles River (ULAR) Enhanced Water - shed Management Program (EWMP) Plan as a priority regional project and will assist the ULAR group in addressing applicable Total Maximum Daily Loads (TMDLs) and water quality priorities. The primary goals of the Project were to improve water quality while providing multiple bene - fits. The Project will divert and capture wet- and dry-weather runoff from over 940 acres, effectively reducing pollutant loads that would otherwise enter Pacoima Wash and the Los Angeles River. The captured runoff will be pretreated and then discharged into a subsurface storage system that will facilitate infiltration at the San Fernando Regional Park, resulting in groundwater recharge. In addition to recharge and water quality benefits, the Project will have additional benefits including flood control benefits and public outreach benefits (outreach events and permanent signage). Impact: The 9.5-acre park includes the San Fernando Regional Pool and Community Center, a children’s play area, and athletic fields. Surrounded by urban development, the park is bound by a Metropolitan Transit Au- thority (MTA) railway to the west along First Street, industrial parks on the south and east corners, and medium-density housing to the north on Park Avenue. The Project ensures continued use of San Fernando Recreation Park by the DAC seeking respite from the stress of a highly urbanized environment. The Project includes the following improvements: estab- lishment of landscapes around the subsurface storage system, restoration of the baseball field, restoration of the existing irrigation system, replace - ment and restoration of light poles and electrical conduit, and restoration of streets and sidewalks. The Project enhances the community’s quality of life by encouraging recreational activities that help maintain a healthy community.

City of Conroe Central Wastewater Treatment Plant Lockwood, Andrews & Newnam, Inc. (LAN) Project Location: Conroe, Texas Project Start Date: 5 December 2019 Project Completion: 30 November 2022 Project Team: LAN, LEM Construction
Project Summary: The Conroe Central Wastewater Treatment Plant (WWTP), a $60 million greenfield project, was conceived to bolster the wastewater treatment capacity for the City of Conroe, one of the fast- est-expanding cities in the United States. Designed and implemented by Lockwood, Andrews & Newnam, Inc. (LAN), the initial phase commenced with a 6.0-million gallons per day (MGD) capacity, with provisions to expand up to 12.0-MGD in response to the city’s burgeoning population and subsequent wastewater treatment demands. A key facet of the project was its commitment to economical and energy-efficient solutions, evident through its ability to facilitate future expansions without enlarging the secondary treatment aeration basins and by engineering a design that can offset operational costs through gas-to-energy production adaptations. Impact: The Conroe Central Wastewater Treatment Plant (WWTP), with its innovative features and future-ready design, significantly impacts the environment and community in a plethora of positive ways. From the ability to implement carbon diversion biological processes to efficient en - ergy usage, it demonstrates a commitment to sustainability and a reduced carbon footprint. In light of Conroe’s status as one of the fastest-growing cities in the country, the additional WWTP capacity is pivotal, enabling the city to cater to its expanding populace and developmental projects sustainably. This expansion not only furnishes the necessary infrastructure to support the city’s swift growth but also ensures that this development does not come at the expense of the environment.
