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.
