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.

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.

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.

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.
