Hughes Road Rehabilitation
Houston, Texas
Construction Cost
$20M
Project Distance
2.5mi
OTHON served as Prime Consultant and Project Manager for the rehabilitation of 2.5 miles of Hughes Road, from Beltway 8 to the City Limits in Southeast Houston. The project involved full pavement reconstruction and utility upgrades to improve safety, mobility, and service reliability for the surrounding community.
Our team provided preliminary engineering, final design, and construction administration services, overseeing roadway, drainage, and utility improvements. Key elements included water and sanitary sewer line replacements, storm sewer design, intersection signal upgrades, and coordination with multiple agencies. All improvements were designed in accordance with the City of Houston Infrastructure Design Manual to ensure long-term performance and compliance.

Holmes Road Sanitary Sewer, Buffalo Speedway to Knight Road
Houston, Texas
Construction Cost
$8.6M
Project Distance
1.7mi
OTHON prepared construction documents for approximately 9,000 linear feet of 42-inch and 48-inch fiberglass-reinforced gravity sanitary sewer along Holmes Road, extending from Knight Road to Buffalo Speedway. The project connects to an existing 84-inch trunk line and supports future development in the area.
Our scope included condition assessments, alternative design evaluations, permitting, and construction administration. To minimize disruption, trenchless micro-tunnel technology was used for key segments. OTHON also coordinated with community developers and provided funding support exhibits.
Design challenges included a deep, custom junction box to transition flows between sewer lines, mitigation of hydrogen sulfide release, and extensive geotechnical investigations near a salt dome and abandoned oil wells. Environmental constraints were incorporated into the construction cost estimate to ensure project feasibility and resilience.

Magnolia Point Unserved Area Sanitary Sewers
Richmond, Texas
Construction Cost
$8.4M
Project Distance
300ac
OTHON provided planning, design, and construction administration services for the Magnolia Point Sanitary Sewer project near Lake Houston. The project replaced aging septic systems with over 21,000 linear feet of sanitary sewer lines and 34,000 linear feet of service leads, connecting approximately 560 homes to a modern sewer system.
Using ArcGIS and H&H modeling tools, OTHON developed flow projections and integrated City of Houston data into GIS-based mapping. The design incorporated open-cut and trenchless methods, watertight manholes, and elevated gas release vents to address high groundwater conditions. The project improves public health, protects water quality, and supports future residential growth.

Ledge Street Improvements
Houston, Texas
Construction Cost
$2.3M
Project Distance
211ac
OTHON served as Prime Consultant to the City of Houston for the Ledge Street Improvements project, delivering preliminary and final design, along with construction administration. The project upgraded 7,100 LF of neighborhood streets from rural asphalt to concrete curb-and-gutter, replaced 5,335 LF of aging waterline, and installed 3,200 LF of new sanitary sewer.
Additional improvements included 10,500 LF of sidewalks and 2,400 LF of new storm sewer to address chronic flooding. Using XP-SWMM modeling, OTHON designed a drainage system to meet City standards for both 2-year and 100-year storm events, incorporating detention and utility conflict mitigation while preserving mature trees along the corridor.

Neighborhood Infrastructure Improvements (AS069)
Houston, Texas
Construction Cost
$23.2M
Project Distance
250ac
OTHON served as Prime Consultant for a comprehensive neighborhood reconstruction project in Houston’s urban core, providing preliminary engineering, final design, bid-phase support, and construction administration. The multi-disciplinary effort modernized approximately 30,000 linear feet of roadway, upgraded water and sewer systems, improved drainage infrastructure, and enhanced pedestrian and bicycle access—all while meeting IDM, TAS/ADAAG, and Texas MUTCD standards.
Design strategies prioritized tree preservation, utility conflict resolution, and context-sensitive streetscape improvements. Through extensive coordination with city departments, utility providers, and community stakeholders, the project successfully balanced infrastructure upgrades with neighborhood character, resulting in safer utility access, improved drainage resilience, expanded multimodal connectivity, and enhanced public lighting and safety.

6 Lift Stations Renewal & Replacement
Houston, Texas
OTHON provided engineering services for the renewal of six critical wastewater lift stations across Houston, including Bintliff, Farther Point, Gessner No. 1 & 2, Park Ten No. 2, and Willowbend. The project included structural, mechanical, electrical, and instrumentation upgrades to improve resiliency, capacity, and operational reliability. OTHON developed a Preliminary Engineering Report, advanced final designs, and supported construction while maintaining continuous operation through phased planning and temporary systems.
Key improvements included converting five stations to submersible configurations for enhanced safety and efficiency, elevating equipment in flood-prone areas, and integrating underground detention systems to meet drainage standards on constrained sites. Innovative reuse of existing infrastructure, shaped grout designs for flow efficiency, and aesthetic treatments—such as murals and landscaping—ensured both technical performance and community acceptance. The project met aggressive EPA compliance deadlines through coordinated stakeholder engagement and a focused delivery approach.

Bering & San Felipe Deep Sanitary Microtunneling
Houston, Texas
Construction Cost
$9.2M
Project Distance
1.3mi
OTHON provided engineering services for the abandonment of two major wastewater lift stations—Bering and San Felipe No. 2—and the construction of new deep sanitary trunk lines to improve system capacity and reliability. The project included 6,700 linear feet of fiberglass-reinforced trunk sewers (30–48 inches) and local PVC collector sewers (8–15 inches). OTHON evaluated multiple alignment alternatives during preliminary design and advanced the selected route through final design and construction administration.
To minimize disruption in a dense urban corridor, large-diameter sewers were installed using trenchless microtunneling technology. The team developed traffic control plans to maintain mobility across four major thoroughfares and coordinated with utility providers to resolve conflicts. Additional support included securing temporary easements and helping the City obtain project funding. The project met EPA Consent Decree requirements through strategic planning, stakeholder coordination, and innovative design solutions.
