DBE Certification for Site Preparation Contractors in California
Site preparation work—clearing, grading, excavation, and earthwork—is a workhorse scope on highway, transit, and airport projects, and it is one primes regularly use to meet DBE participation goals. For a site prep firm, DBE certification can be the difference between getting the call and getting passed over.
Crown Consulting helps California site preparation and earthwork contractors get DBE certified and position their scope so primes can use it.
Why Site Prep Is a High-Demand DBE Scope
Almost every federally funded infrastructure project starts with site work. Primes need DBE participation, and site preparation is a large, clearly defined scope that is straightforward to subcontract—which makes certified site prep firms attractive partners on Caltrans, FHWA, and FTA-funded jobs.
NAICS 238910 and Your Scope
Site preparation contractors are typically classified under NAICS 238910 (Site Preparation Contractors), often alongside related excavation and earthwork codes. Carrying the right codes ensures primes find you in the CUCP directory for grading, excavation, and demolition scopes. We make sure your NAICS codes and work history reflect the site work you actually self-perform.
Commercially Useful Function and Equipment
DBE credit requires a commercially useful function under 49 CFR 26.55—you must manage the work and perform it with your own forces, not act as a pass-through. For earthwork firms, equipment matters: owning or leasing your own equipment and running your own crews is central to showing you perform a genuine function. Crown helps you structure and document operations so your role holds up to a commercially useful function review.
Eligibility Essentials
The certification framework is the same as any California DBE: at least 51% ownership and real day-to-day control by one or more owners who can demonstrate individual social and economic disadvantage, a personal net worth under $2.047 million, and a Personal Narrative with supporting evidence. For the full framework, see our main DBE certification page.
How Crown Consulting Helps
Crown was founded by attorneys who spent their careers in California's contractor and utility world. We prepare your complete certification package, draft the Personal Narrative, organize the exhibits, and—critically—position your scope and NAICS codes so the right primes can find and use your DBE status.
For site prep firms, we pay particular attention to equipment documentation and NAICS alignment—the two places earthwork applications most often run into trouble.
