Other Projects

Humboldt River Floodplain Analysis

Humboldt River Floodplain Analysis

HAL assisted Elko City, Nevada, with flood delineation and flood mitigation projects. The effort included detailed hydraulic analysis of a reach of the Humboldt River, plus analysis and design of flood mitigation measures on Metzler Wash, Culleys Gully, and Eight Mile Creek. HEC-RAS water surface profiles were used to analyze existing flooding potential and evaluate alternative mitigation measures. Letters of Map Revision (LOMRs) were successfully submitted to FEMA for the projects resulting in improved floodplain conditions.

Water Rights Support

Water Rights Support

For over 40 years HAL has provided water rights engineering support to municipalities, private clients, and over 20 legal firms in Utah and Idaho. Services have included due diligence and site investigations supporting land purchases, surface and groundwater studies, water use evaluations, water right ownership evaluations, new filings, diligence claims, change applications, proof of appropriation, proof of beneficial use, and water right hearing support.

Litigation Support

Litigation Support

HAL provides engineering litigation support to many local and regional attorneys and legal firms. Services include historic or projected flood conditions, flood damage investigation, post-fire runoff evaluation, flood debris retention, mine tunnel flows, canal use rights, irrigation demand, well failures, surface and groundwater interference, wetland creation, nuisance water, engineer’s duty and professional conduct, property boundary disputes, and development potential and land condemnation.

Spanish Fork Water Master Plan

Spanish Fork Water Master Plan

HAL completed a major update to Spanish Fork City’s Drinking Water Master Plan. Key technical issues included understanding the City’s multi-zone water distribution system, projecting water demands that consider the long-term effects of drought and conservation, developing innovative approaches to pipe network modeling, and updating the City’s GIS-based water infrastructure database.

Jordan River Diversion Structure

Jordan River Diversion Structure

HAL prepared designs and specifications for the Jordan River Diversion Structure Replacement. The structure, located on Utah’s Jordan River just north of 2100 South in Salt Lake City, diverts a portion of the Surplus Canal flow into the Jordan River to meet downstream irrigation requirements and control flood flows. The project features two motor-driven 10′ × 14′ radial gates, energy dissipation blocks within the gate, precast 10′ × 5′ box culverts, and downstream erosion protection.

Cache Water Restoration Project

Cache Water Restoration Project

HAL was part of a multi-firm team that designed this $18 million project in Cache County, Utah. It enclosed several canals using precast concrete box culvert, cast-in-place concrete box culvert, reinforced concrete pipe (RCP), PVC pipe, and HDPE pipe. The project also included a new diversion structure on the Logan River with fish screens and an automatic brush cleaning system. The project was designed, constructed, and opened in just over one year. In 2013 it was named “Outstanding Municipal/Utility Project” by Utah Construction & Design.

Montrose Landfill Phasing Plans

Montrose Landfill Phasing Plans

HAL provided planning for Waste Management at their Montrose, Colorado, municipal landfill that included a phasing plan through the year 2039. HAL used AutoCAD Civil 3D with an existing topographic surface to define the ultimate closure surface and determine construction phases in 5- to 10-year increments. A phased drainage plan was also defined. Waste Management used the plans to prioritize capital improvements and allocate resources to future budgets.

Peoples Canal Piping Project

Peoples Canal Piping Project

HAL planned, designed, and provided construction engineering services for the Peoples Canal Piping Project in Daggett County, Utah. The project enclosed the existing canal with nearly 8 miles of HDPE pipe with diameters ranging from 24 to 48 inches. The project met of all of its goals—including completion before the irrigation season—and has conserved water, reduced operating costs, and improved reliability. The project won an Engineering Excellence Merit Award from ACEC Utah.

Freeway Pump Station

Freeway Pump Station

This drinking water project in Draper, Utah, included design and construction of a booster pump station with two 400 horsepower, 1700 gallon-per-minute vertical turbine pumps with pump barrels. The project required geotechnical investigation, hydraulic analysis, transient surge analysis, surge tank design, building design, variable frequency drive design, and a chiller cooling system.

Winder Tank

Winder Tank

For Granger-Hunter Improvement District, HAL provided the design of a 4-million-gallon rectangular reinforced concrete storage tank and an 18-inch-diameter inlet/outlet pipeline. The project included permitting, site surveying, geotechnical evaluation, and design of the reservoir, valve vault, piping, and overflow pipeline. It also included electrical design and construction, tying into GHID’s existing SCADA system, and preparing a detailed landscape and irrigation plan to meet local requirements.

Market Station Sewer

Market Station Sewer

South Salt Lake City selected HAL to design and manage construction of 3,800 feet of 30-inch-diameter trunk sewer along Andy Avenue, 300 West, and Utopia Avenue. The project included surveying, loading calculations, hydraulic modeling, geotechnical issues, pipeline design, conflicting utilities, UTA Trax (light rail) crossing design, easements, and cost estimation.

Highland Wastewater Master Plan

Highland Wastewater Master Plan

Highland City, Utah, has grown rapidly in recent years, straining its wastewater collection system. Consequently, the City desired a master plan that would both address existing system deficiencies and recommend future infrastructure to support further growth. HAL completed a Wastewater Collection System Master Plan with a schedule of capital projects to meet these needs.

Barton Creek Flood Control Project

Barton Creek Flood Control Project

Davis County, Utah, selected HAL to design and assist during the construction of improvements to the Barton Creek flood conveyance system. The project included the design and construction of 3,200 feet of 9′ × 4′ box culvert placed in interstate highway and commuter rail rights-of-way. The project utilized open cutting in the 500 West underpass crossing of I-15 northbound lanes, open-cut crossing of I-15 southbound lanes, and open-cut crossing of Pages Lane.

Valley Downs and Wheeler Wastewater Pump Stations

Valley Downs and Wheeler Wastewater Pump Stations

HAL assisted with the construction of two wastewater pump stations for Granger-Hunter Improvement District. Both are of the dry well / wet well prefabricated type. The Valley Downs Pump Station includes two pumps rated at 500 gallons per minute; the Wheeler Pump Station contains two pumps rated at 650 gallons per minute. Both pump stations are approximately 30 feet deep and were constructed inside sheet piling to accommodate small construction sites in residential neighborhoods. Both feature backup power generation.
