Architectural Rendering of a Sustainable House

Living Building Challenge Custom Home — Nevada

Living Building Challenge Custom Home
Blue Diamond, Nevada

HCF provided civil site engineering for a custom home in Blue Diamond, Nevada, pursuing Living Building Challenge (LBC) Petal Certification,  a sustainability standard that exceeds LEED and traditional green building requirements. The desert climate called for a design built around water conservation and self-sufficiency.

HCF designed the site grading and drainage systems to support low-flow fixtures, native landscaping, and rainwater harvesting to an underground cistern that minimizes evaporation and maximizes retention. The stormwater design incorporated bioswales and dry retention ponds, helping the home achieve LBC Petal Certification.

The Church of Jesus Christ of Latter-day Saints planned a new 355-acre campground in the mountainous terrain of Hull Canyon, designed to support large youth and group activities. The remote, steep site required a reliable wastewater system for hundreds of users while meeting Idaho Department of Environmental Quality requirements and protecting groundwater.

HCF provided civil and environmental engineering for the campground, including site planning, utility design, and roadway coordination. HCF designed a septic system serving approximately 300 visitors, with multiple lift stations and a distributed drainfield exceeding 40,000 square feet — incorporating water conservation measures for long-term, low-impact operation.
