Bitner Creek Crossing – Sloop

Bitner Creek Crossing – Site Infrastructure & Bridge Design

Summit County, Utah

HCF provided full civil development services for a private 10-acre property in Summit County, Utah, including the design of a 450-foot roadway and a 20-foot span bridge crossing over Bitner Creek. The creek is designated as a FEMA Zone AE waterway with an established floodway, requiring careful hydraulic consideration and regulatory coordination throughout the design process.

HCF’s scope included water line design featuring a 10-inch hot tap and service line, multiple valves, and thrust blocks. All water system appurtenances were designed in conformance with Mountain Regional Water District and Division of Water Quality standards, as well as American Public Works Association (APWA) and American Water Works Association (AWWA) standards, ensuring full regulatory compliance for this complex multi-discipline infrastructure project.

Price River – CLOMR/LOMR Floodplain Analysis

Spring Glen, Utah

HCF performed hydraulic modeling and floodplain mapping to support a FEMA Conditional Letter of Map Revision (CLOMR) for a property largely located within the floodplain and floodway in Spring Glen, Utah. The project involved complex floodplain and floodway modification analysis to facilitate site development while ensuring no adverse impacts to adjacent properties or facilities.

HEC-RAS modeling was used to evaluate 100-year flood conditions and assess the effects of proposed fill and site modifications. Model results were mapped onto base mapping and used to support FEMA submittal documentation for floodplain and floodway revisions. Should the impacts of securing a CLOMR prove infeasible based on financial or risk factors, a Letter of Map Revision (LOMR) will be filed to narrow the floodway.

Little Cottonwood Creek Tributary – Slope Mitigation

Cottonwood Heights, Utah

HCF provided an engineering evaluation of slope stability and structural support for an existing residence in Cottonwood Heights, Utah, in response to City review under the Sensitive Lands ordinance. Field observations and survey data were used to assess the relationship between the hillside, existing improvements, and the home’s structural zone of influence, confirming that slope conditions do not adversely affect the support of the residence. Based on conservative geometric assumptions and stability criteria, the home was determined to meet accepted static and seismic safety factors.

HCF’s scope also included preparation of grading and erosion control plans, development of rockery stability calculations, and coordination with project stakeholders to support City review and approval. The project emphasized restoring long-term slope stability through appropriate erosion control measures and revegetation of the disturbed hillside adjacent to the Little Cottonwood Creek tributary.

North Las Vegas VA – Life Safety Barrier Design

North Las Vegas, Nevada

HCF provided structural and mechanical design services for a life safety barrier enhancement project at the North Las Vegas Veterans Affairs facility. The project involved the design of a fence barrier system for an existing stairwell, including safety handrails and an inner fence to restrict stairwell access, with the goal of enhancing life safety at the facility.

HCF’s scope included mechanical and structural design for all fasteners and attachments connecting the new barrier system to the existing stairwell structure, ensuring the design met applicable safety standards while integrating with existing site conditions.

Tooele Army Depot – North Water Distribution System Improvements

TEAD North – Water Distribution System Improvements

Tooele Army Depot, Tooele, Utah

HCF provided water distribution system improvements for the Morale, Welfare and Recreation (MWR) water system at Tooele Army Depot in Tooele, Utah, with the primary objective of meeting fire flow requirements. The project included a comprehensive review of previous hydraulic analyses, reports, and model scenarios using EPANet modeling software.

HCF developed cost-efficient improvement recommendations including extending metered pipelines, installing detector checks for flow monitoring, incorporating pressure zone data, adding a storage tank to the existing network, and installing a backup generator. HCF also prepared detailed reports identifying system deficiencies in the MWR area and outlined actionable solutions to bring the water distribution system into full compliance with fire flow standards.
