Trancas Creek and Lagoon Feasibility Study

During the 1960’s, a two-section 2,000-foot concrete lined channel was added to Trancas Creek for flood control purposes. Time demonstrated that the concrete channels, drought-driven low water levels, and a road crossing culvert created significant fish barriers and negative impacts to the life cycle of natural creek and lagoon resources. The goal of the Trancas Creek and Lagoon Feasibility Study project conducted for the Resource Conservation District of the Santa Monica Mountains was to assess the removal of fish passage barriers and improving habitat for endangered aquatic species.

University and Josephine Reconstruction

Huitt-Zollars prepared construction contract documents for the reconstruction of University and Josephine between Cherry Creek North Drive and 6th Ave. This Better Denver Bond Project included replacement of the deteriorated pavement with new concrete pavement (expected life span of 30 years), construction of new ADA compliant pedestrian facilities; and new traffic signals at 1st, 2nd, 3rd, and 4th Avenues. The project was constructed in conjunction with storm drainage improvements designed to reduce the frequency and impacts from localized flooding in the Cherry Creek area.

Long Road Improvements

Long Road reconstruction improvements included approximately 4,950 LF of an existing two-lane residential collector street; the project included Long Lane and Jackson Street. The project scope incorporated the evaluation and optimization of elements in order to maximize pedestrian uses, surface and subsurface drainage system, resolution of ADA issues, pavement section, alignment, and streetscape.

Tower Road Widening

As a keynote project in the City’s capital improvement program, the Tower Road Widening project will improve Tower Road from the eastbound ramp intersection (south side) of the Peña Blvd and Tower Rd interchange to 103rd Ave. The project will widen the existing two-lane facility to four lanes divided with a raised landscaped median.

Pearland Public Safety Building

Huitt-Zollars served as the City of Pearland’s project manager for the design-build of a new 83,000-square-foot, $19.9 million, Public Safety Building. The two story, LEED-Silver facility houses the City’s Departments for Police, Courts, Utility Billings and Tax Office. Huitt-Zollars scope included preparation of guideline specifications, conceptual floorplans, site plan, and facility scoping documents. Huitt-Zollars assisted the City in a two-step design-build procurement process, prepared detailed performance and quality criteria, as well as the design-build Reques

Houston TranStar Facility

As one of the first high-tech transportation and emergency management centers in the United States, this three-level, 52,000-SF facility handles all traffic and emergency management control within metropolitan Houston. The building facade was designed to withstand hurricane force winds; the mechanical system design allows the facility to operate independently during a power blackout or emergency conditions.

I-405 South Bellevue Widening

Huitt-Zollars completed drainage and landscape designs to widen four miles of interstate freeway in a congested urban area, through this $124 million design-build project. The drainage system included five wetland facilities along with water quality media filtration embankments and a water quality monitoring basin. Improvements included stormwater drainage and control structures, rehabilitation of culverts and pipes, water quality monitoring facilities, slope drainage behind retaining walls, and a new 2.5-acre off-site wetland mitigation site. Roadway restoration plans were prepared.
