In Marin County, landscape and grading work is inseparable from civil engineering. Hillside lots require retaining systems, drainage management, and soil stability solutions that must be engineered before any planting or hardscape is specified. We manage the civil and structural aspects of landscape construction — grading, drainage, retaining walls, and irrigation infrastructure — as part of a unified scope.
We partner with Marin County's premier landscape architects and designers to deliver complete estate landscapes that integrate naturally with the surrounding terrain. Our role is to execute the civil and construction scope with precision — preparing the canvas for planting and finishing with the same rigor we bring to interior construction.
ConstruBay (CSLB #1106798) is based in Mill Valley and has executed landscaping and grading projects across Marin, Sonoma, and Napa Counties.
What Is Included
The Marin Advantage
Grading and landscape construction in Marin County triggers a range of regulatory requirements depending on project scope — including grading permits for earthwork above certain cut/fill thresholds, stormwater pollution prevention plans (SWPPP) for disturbed areas above 1 acre, and in many hillside areas, geotechnical reports for retaining wall systems above 3 feet in height. Our PlanPass.ai platform manages the multi-agency permit coordination that significant landscape and grading projects require in Marin County. We have completed hillside grading projects throughout Mill Valley, Tiburon, Ross, and Kentfield, and we maintain strong relationships with the geotechnical engineers and landscape architects whose expertise is required on complex Marin hillside projects.
