When the City of Fort Worth identified critical maintenance and safety concerns at the Oakland (Fosdick) Lake Dam and Lake Como Dam, BHB was engaged to evaluate existing conditions and develop long-term repair and improvement solutions that would bring both structures into compliance with Texas Commission of Environmental Quality (TCEQ) dam safety standards—while preserving their roles as community and park amenities.
BHB began with detailed onsite inspections to confirm deficiencies noted in routine TCEQ inspection reports, identify additional issues, and prepare inspection and recommendation reports with Engineer’s Opinions of Probable Cost (EOPCs) for multiple improvement options. These studies addressed erosion, structural deterioration, hydraulic capacity, and regulatory constraints, and ultimately led to BHB being retained for full design services for both dams.
At Oakland (Fosdick) Lake, the project was driven by the failure of the original masonry and concrete culvert spillway, which had collapsed and required replacement and upsizing. The design was further complicated by the presence of Waters of the U.S. (WOUS), a significant backwater effect from Interstate 30 downstream of the dam, and the requirement that the modified dam safely pass the 75% Probable Maximum Flood (PMF)—approximately three times larger than the 100-year storm—without increasing 100-year discharge rates. To address these constraints while minimizing park impacts and controlling costs, BHB designed a labyrinth weir with openings at the normal pool elevation and a parapet wall along the dam crest. This solution safely conveyed extreme storm events, maintained pre-project 100-year discharge rates, qualified for a Nationwide Permit under Section 404 of the Clean Water Act, and allowed for the installation of a 52-foot pedestrian bridge to restore the park trail crossing.
At Lake Como, the dam and spillway are integral to Merrick Street, which connects the surrounding community and provides pedestrian access around the lake. BHB’s work focused on repairing the eroded upstream slope, addressing cracking and spalling in the spillway, stabilizing drainage channels, and integrating wave-action protection to prevent future deterioration. These repairs were coordinated with improvements to the adjacent sidewalk to enhance pedestrian safety and access, ensuring the dam continued to function as both infrastructure and a community asset.
Throughout both projects, BHB worked closely with TCEQ and environmental consultants to streamline permitting, address Waters of the U.S. constraints, and keep the projects moving despite evolving regulatory and construction challenges. Advanced hydraulic and hydrologic modeling was used to account for localized inflows, backwater effects, and downstream culvert limitations—conditions that could not be fully captured using standard modeling approaches. Construction for Oakland (Fosdick) Lake is currently underway, with future phases including the preparation of Emergency Action Plans and Operation and Maintenance manuals for both dams. Together, these projects deliver resilient, regulation-compliant infrastructure solutions that protect public safety while enhancing Fort Worth’s park spaces for years to come.

As a young kid, Quaid Wright aspired to be a detective like Sherlock Holmes. Once he reached high school, he realized that following in his father’s footsteps to become a civil engineer would be a better fit. He has an innate aptitude at science, math, and problem solving, so engineering came naturally, but due to his affinity for gaining and sharing knowledge, he thinks he might have also done well as a math or history teacher.
Quaid joined BHB after graduating from the University of Texas at Arlington with a degree in civil engineering. He specializes in hydrology and hydraulics, but has gained a diverse range of experience in his time in the industry.
In his free time, he enjoys learning about niche facets of history, scientific discoveries, mathematical concepts, and even the nuances of language and vocabulary. He reads books and watches YouTube videos, particularly ones with educational/informational content, and he enjoys video games that require strategic thinking, problem-solving abilities, or those that weave captivating narratives. He prefers to visit natural areas, museums, and historical monuments over crowded venues or events.
He is married to a wonderful woman who is studying to be an art teacher. Together they have a dog, a cat, and a lizard, and hope to start a family someday soon.
