Kenall was responsible for developing the plans, specifications, and cost estimates for two distinct Design-Bid-Build packages, both focused on improving levee systems. Package 1 addressed the Colorado River Levee Phase 2, while Package 2 focused on the Baughman Slough.

Package 1 involved the extension of the Colorado River Levee, including three miles of earthen levee and one mile of floodwall. It incorporated crucial features such as the Black-Collins sump areas, Polk Street storm drainage improvements and pavement, closure structures, and a one-mile road elevation for FM102. Grading and slope protection for the Colorado Riverbanks near the sluices were designed, supplemented with rock riprap to control erosion. Post-construction seeding and erosion control measures were detailed as part of the package.

Package 2 focused on the Railroad Levee, Baughman Slough Levee, and floodwall design, alongside culverts and a significant widening of the channel bottom from 50 to 125 feet over a four-mile stretch. This package also included the design of three replacement bridges: the Moers Lane Bridge and Fulton Street Bridge, built as multi-span concrete structures on drilled piers, with spans of 175 feet and 204 feet, respectively. Efforts were made to optimize drainage and minimize erosion impacts on the channel slopes.

Kenall developed AutoCAD Civil 3D drawings at progressive stages—30%, 60%, 90%, and 100%—and provided detailed technical specifications. The floodwall design adhered to stringent engineering standards (EM 1110-2-2000, EM 1110-2-2100, EM1110-2-2502, and EM 1110-2-2906), ensuring compliance. These designs improved flood risk management for the City of Wharton.

Work performed on these projects was completed under the Kenall-Freese & Nichols 8a Mentor-Protégé Joint Venture (KFNI JV).
