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.

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.

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.
