Project Highlights

  • Stabilization design for road cuts and slopes within a complex relic landslide area.

  • Design of 45,000 square feet of soil nail, ground anchor, and Hilfiker wall systems.

Project Description

The Maryland Creek Ranch development involved the construction of a 240-unit residential community on a complex relic landslide site. Our team served as project manager for the design and provided construction oversight, helping address the challenging geotechnical conditions necessary to support site infrastructure and roadway development.

The project required extensive slope stabilization and groundwater management measures. The team directed the design of soil nail walls, grouted post-tensioned ground anchors, mechanically stabilized earth (MSE) walls, and Hilfiker wall systems to stabilize slopes and road cuts. Site subsurface drainage systems were also designed to control groundwater and further improve long-term site stability.

Stabilization improvements included approximately 4,500 feet of horizontal drains, 13,000 feet of underdrains, and 45,000 square feet of soil nail, ground anchor, and retaining wall systems. The team collected and evaluated geotechnical data from site borings, inclinometers, and piezometers and developed a comprehensive geotechnical design report. Full construction drawings were prepared for the retaining walls and subdrain systems.
