The City of Coralville and Iowa DOT have partnered to improve the I-80 and 1st Avenue Interchange. The existing diamond interchange will be replaced with a Diverging Diamond Interchange (DDI) design to handle projected traffic volumes. One of the biggest safety and congestion issues is tied to the number of left turns at the interchange.

HR Green is providing construction engineering and inspection services for the construction of four direct connectors at the SH 249 / SH 99 interchange. The $92 million project, which will improve mobility in the region with a more efficient connection between the Grand Parkway (SH 99) and Tomball Tollway (SH 249).

The City of Waukegan was in need of an operational evaluation of the Water Plant and the water distribution system as well as a Risk and Resilience Assessment (RRA) for their Water Treatment System.

Subsidence rules limit the amount of groundwater pumping available for drinking water within Harris County. To comply with these requirements and meet the growing demand for water, the City of Pasadena (COP) contracted with the City of Houston (COH) to purchase treated surface water. However, the existing COP metering station at the Southeast Water Purification Plant (SEWPP) did not allow COP to take the full contracted amount of 40 MGD. Improvements to the COP’s system were needed.

Declining attendance forced the closure of Arlington’s only school in 1985 and the structure remained underutilized for two decades while the building deteriorated and became a dumping ground.

Del Webb The Woodlands is a nearly 200 acre, active adult, master-planned community comprised of 570 single-family homes. The community blends with the surrounding character of the area while using contemporary architectural themes to set the community apart from neighboring development.

El Paso County had repeatedly heard from its rural residents that internet speeds and service were unacceptable. The County needed to determine how best to address complaints from constituents? Would broadband help make the area more economically competitive? How would the County prioritize diverse socio-economic needs? While Colorado Springs is well-served in one of five

Broadband coverage can be problematic, particularly in rural areas. Without specific connectivity data, municipal leaders do not know what options they might have to improve broadband, providers do not know where needs are, and maps that are used to determine grants can be inaccurate to the point where grants might not be available where they are needed.

The Woods Creek Watershed-Based Plan (WCWBP) identified the creek as a critical area for improvements and recommended it as one of the highest-ranking implementation projects in the WCWBP for streambank and channel restoration and riparian area restoration and maintenance.

I-90 is the only interstate that cuts through McHenry County and the new interchange at Illinois Route 23 is the county’s first. The long-awaited interchange intersects at Illinois Route 23 on the Jane Addams Memorial Tollway (I-90) and features roundabouts and all-electronic tolling at the I-90 exit and entrance ramps to improve safety and mobility.

The reconstruction of Taxiway Kilo included several unique and challenging components necessary to allow work to occur while minimizing impacts to airport operations at St. Louis Lambert International Airport, including some aspects that have rarely been attempted before, if ever.

The L27 Lift Station replaced an existing, aging facility in Hopkins, Minnesota, which was over 40 years old, had significant condition issues, and lacked redundancy. In addition, the existing lift station was undersized with little storage.

The Trout Brook Nature Sanctuary and Regional Trail, which was developed on a 42-acre urban brownfield site in Saint Paul. The project’s key design feature was the re-creation of approximately 3,000 feet of the Trout Brook after decades of confinement within an underground storm tunnel (the Trout Brook Interceptor).

Groundwater was potentially a new water source for Iowa City as it has historically utilized the Iowa River for nearly 100 percent of its supply. The City needed help with recommendations for expanding its water source, treatment, distribution, and storag

Alluvial wellfields consisting of several dozen wells – both collector and vertical types – along the Big Sioux River have historically supported Sioux Falls’ water supply. HR Green, in partnership with Leonard Rice Engineers (LRE), was retained by the City to provide research and preliminary testing, hydrogeologic testing, well siting, and design and construction phase services for wellfield improvements.
