Civil Site Design Services

We handle civil site grading design in Southern California with a focus on clean approvals and practical construction. Our work starts with detailed site plans that map the full layout—property lines, building footprint, paving, and utilities—then develops site grading plans that set elevations for pads, drives, and walks so drainage, constructability, and code compliance align from the start.

Grading is the foundation of a successful site build. We analyze existing topography and conditions, then design cut/fill, slopes, and contours for long-term stability and functionality—using rough grading to establish the overall landform and fine grading to prepare surfaces for paving and construction. The goal is simple: move water away from structures, avoid ponding, reduce erosion risk, and support a permit-ready package that contractors can build efficiently.

Drainage is integrated into everything we do. Our stormwater drainage design includes custom systems—pipes, inlets, basins, culverts, and overland flow paths—supported by hydraulic evaluation to meet regulatory requirements and prevent downstream impacts. We coordinate utility site layout (water, sewer, gas, electrical) and provide erosion control plans, plus parking lot design and site access/circulation plans to keep vehicles and pedestrians moving safely while protecting the site throughout construction and beyond.
