Excavation in Princeville
Princeville sits on the bluffs above Hanalei Bay — high-value parcels, strict CC&R review, and erosion-sensitive sites that demand careful grading and drainage planning.
Working on the ground in Princeville
Volcanic clay, steep coastal bluffs, and heavy North Shore rainfall (90+ inches/year) make drainage design the single biggest variable on any Princeville project.
What we run here
Foundation excavation for luxury homes, drainage swales, retaining wall prep, septic system installation, and driveway construction on sloped lots.
