Who Do You Hire for a Grading Plan in Los Angeles?

We get asked this question regularly. Someone is planning a project, they talk to an architect, the architect mentions grading, and then the question comes up: who actually produces this grading plan?

Here is the short answer.

A Civil Engineer Produces Grading Plans

You hire a civil engineer, not an architect. Architects design buildings. Civil engineers design site work.

The grading plan shows how the land will be shaped, how water drains across the property, and how the building sits on the site. It involves calculations for cut and fill volumes, slope stability, and drainage patterns. This is civil engineering work.

What the Grading Plan Actually Is

A grading plan shows:

• Existing topography and spot elevations
• Proposed topography after construction
• Drainage patterns and flow directions
• Retaining wall locations and heights
• Driveway grades and transitions
• Cut and fill calculations

LADBS requires this plan for hillside properties, basement excavations, pool installations, and any project that substantially changes how water moves across the site. The plan must bear a civil engineer’s stamp and signature.

When to Hire a Civil Engineer

Hire us early. Before the architect locks in the building design.

Civil engineering constraints often affect the building design. If the driveway grade is too steep, the building footprint shifts. If the retaining wall height hits a limit, the building sits differently. If the drainage cannot be solved within the lot, the design changes.

Getting a civil engineer involved during schematic design prevents expensive redesigns later.

The Short Version

For grading plans in Los Angeles, you need a civil engineer. Architects coordinate the overall design but do not produce the site engineering documents. Contractors build according to the plans but do not create them.
