The North Service Center complex includes a two-story administration building, a 200-person pavilion, a maintenance facility, a distribution warehouse, fueling and wash facilities, parking, landscaping, berms, and a significant storm water quality feature. The entire 22-acre tract was hydraulically designed to surface drain through and be naturally filtered by a series of cascading sedimentation ponds, grassy swales, vegetated filter strips, natural filtering, constructed wetland areas into a dual purpose polishing, and detention pond. An outlet structure was engineered with a vent pipe dri

A major drainage channel, Mauk Branch, was eroding its banks in the backyards of a residential neighborhood, and getting dangerously close to area homes. Following a public meeting with residents, Huitt-Zollars began work on possible solutions to stop erosion and maintain the 100-year flood capacity of the creek, while at the same time be aesthetically pleasing and environmentally sound. Huitt-Zollars located the mean high-water level and went to work on a Corps of Engineers 404 permit. Flood levels were verified by inserting the new cross-sections for the channel into the City’s model.

Huitt-Zollars developed a channel restoration design for a highly urbanized and eroded stream as part of an emergency watershed protection program. Services included a hydrology and hydraulic (H&H) analysis and design, channel restoration, bioengineering, construction documents, and construction observation. Bioengineering techniques were used in conjunction with more traditional engineering methods to develop bank stabilization and grade control structures in order to prevent further erosion of residential property and nearby utilities along a reach of Mary’s Creek.

Huitt-Zollars designed improvements to the Elkins Lake Dam for the Elkins Lake Recreation Corporation. The earthen dam is more than 800 feet in length, 10 feet wide crest and 27 feet high with two spillways: an earthen service spillway and a reinforced concrete emergency spillway.

Huitt-Zollars is providing engineering and construction phase services for the Maintenance of Federally Assisted Channels. These flood control, navigational, and coastal protection facilities were originally constructed by the U.S. Army Corps of Engineers (USACE), Galveston District. Annually, as well as after significant rainfall events, Huitt-Zollars conducts an in-depth condition assessment inspection.

Huitt-Zollars prepared the construction documents for improvements to the 141-foot-wide Gated Structure at the Clear Lake Second Outlet. The gated structure and outlet channel were designed by U.S. Army Corps of Engineers. Improvements to the structure included new safety ladders; replacement of the gate screw-top stem covers with expandable covers; replacement of the gates’ sacrificial anode cathodic protection system; a new hoist system atop the structure; additional galvanized steel grating cat-walk atop the structure; gates and railing.

Huitt-Zollars provided construction management and inspection services for the reconstruction of Shepherd Drive from Westheimer Road to West Dallas Street/Chilton Road, plus northbound and southbound frontage roads of Shepherd Drive from West Dallas Street/Chilton Road to Allen Parkway. The project included the removal of existing storm sewer mains and installation of new pipe (ranging from 24-84 inches in diameter) with new outfall structure and bank stabilization at historic Buffalo Bayou.

Huitt-Zollars provided design and construction administration services to convert a portion of San Antonio Avenue into a two-way street while improving the existing parkway.

Huitt-Zollars prepared a preliminary engineering report and provided final design, bidding, and construction phase services for the reconstruction of 3,000 LF of Pech Road for the City of Houston. The project required replacing existing asphalt street and open ditches with a 41-foot reinforced concrete pavement with curb and gutter and the replacement of approximately 3,000 feet of sanitary sewer lines and waterlines. Other enhancement included bringing the sidewalks and driveways in the neighborhood up to the City’s standard.

Huitt-Zollars provided engineering design and construction phase services for two miles of street, drainage, and utility improvements near Montrose area, north of US 59. The project area consists of a mixture of single-family homes, multi-family apartments, and newly constructed town homes. The project scope included reconstruction of streets and sidewalks to current code, installation of wheelchair ramps, construction of new water and sanitary sewer lines, and improvements to the drainage system.
