CA LIC #1060838 · Licensed & Insured

DW Excavation, LLC is a licensed California general engineering contractor serving San Benito County with expert excavation, grading, utility trenching, foundation work, and site preparation — combining big-project rigor with owner-led accountability on every job.

Licensed. Local. Accountable on Every Job.

Choose a licensed, insured, and local team that treats your site like a jobsite, not a learning crew. At DW Excavation, you get owner-led oversight, clear scopes, and proactive communication from the first walk to final sign-off — keeping schedule, budget, and safety locked in for San Benito County projects.

We bring big-project rigor to every dig: thorough due diligence, utility locates, and permitting support; smart sequencing that reduces conflicts; and documentation that stands up to inspections. Expect tidy staging, verified compaction, and transparent, itemized pricing — so surprises are rare and progress is steady.

Our Excavation Services in San Benito County

From first call to handover, we engineer constructability into every task — balancing cut/fill volumes, access, and safety around utilities. Expect neat staging, proactive SWPPP/erosion controls, and verified compaction to meet your geotech and inspection requirements.

  • Land Clearing & Preparation — Selective clearing, grubbing, and root removal with erosion controls at the edges; we open access, protect trees and fencing, and deliver a clean, build-ready site with minimal disturbance.
  • Foundation Excavation — Over-excavation, moisture-conditioning, and re-compaction per the soils report; footings cut on grade and haul-off coordinated so forms sit on uniform bearing with fewer surprises at pour time.
  • Grading Services — Rough and finish grading tuned to your plans and drainage paths; we shape pads, swales, and drive approaches, balancing on-site materials to reduce import/export and control costs.
  • Trenching for Utilities — Accurate depths and bedding for water, gas, electrical, fiber, and sewer; maintained trench safety and backfill to spec — protecting existing lines and achieving finish elevations that pave cleanly.
  • Road Expansion — Lane and shoulder widening with precise subgrade prep, box-outs, and tie-ins; coordinated traffic control and compaction testing for smooth, durable surfaces ready for paving and striping.
  • Pond Installation — Excavation, shaping, and keying of berms; liner, inlet, and outlet installation with stabilized banks so your pond functions reliably through wet seasons and inspection cycles.

Benefits of Hiring DW Excavation

We combine Central Coast experience with disciplined general-engineering practices to keep your project compliant, on schedule, and on budget. Our team supports encroachment and right-of-way permits where county approvals are required.

  • Licensed & Insured Team — Work delivered by a properly licensed contractor familiar with CA CSLB requirements for excavation scopes.
  • Permit & Utility Coordination — Assistance with San Benito County encroachment/ROW paperwork and utility locates to avoid delays and conflicts.
  • Transparent Pricing — Clear, itemized proposals with value-engineering options that reduce import/export, trucking, and rework.
  • Safety & Compliance — Trench protection, traffic control, and inspection-ready documentation aligned with local standards and project specs.
  • One-Stop Sitework — Excavation, grading, utilities, and surface prep delivered under one accountable team to simplify scheduling.

Our 4-Step Process

  • Consultation & Due Diligence — We review your goals, budget, and schedule; pull plans, soils reports, and utility maps; and walk the site to flag access, haul routes, and constraints — including any county encroachment or traffic-control requirements.
  • Buildable Plan, Sequencing & Controls — We convert design intent into a constructible sequence: survey control, cut/fill plan, trench depths, and staging. Controls include SWPPP, safety plans, and inspection checkpoints aligned with your geotech and agency approvals.
  • Precision Field Execution — Our operators and laborers execute to line and grade with tight tolerances, daily QC notes, and photo documentation. Utilities are potholed where needed, and backfill/compaction is verified so downstream trades stay on track.
  • Closeout, As-Builts & Handover — We deliver as-built elevations and utility locations, finalize compaction and test reports, and complete punch items. Your site turns over clean, safe, and ready for the next trade.

Built for San Benito County Conditions

San Benito County's terrain — from the Gabilan Range foothills to the broad valley floors around Hollister — demands site work that accounts for variable soils, agricultural access requirements, and county permitting workflows. DW Excavation brings direct experience with these conditions.

We understand the local regulatory environment: encroachment permits for work entering the public right-of-way, grading permits for significant cut/fill, and the soil-specific challenges that affect compaction and drainage design throughout the county.

Key Site Considerations

  • Variable clay and loam soils requiring moisture-conditioning before compaction
  • Agricultural tie-ins and access road requirements on rural parcels
  • San Benito County encroachment permit requirements for driveway and ROW work
  • Proximity to creeks and drainage corridors requiring SWPPP compliance
  • Seasonal ground conditions that affect haul routes and scheduling

Common Questions

Answers to the most frequent questions we hear from homeowners, builders, and developers working in San Benito County.

Ask Us Directly ›
Do you service all of San Benito County? +

Yes. DW Excavation regularly serves the Monterey Bay area and neighboring counties and we mobilize to projects across San Benito with established hauling and inspection workflows. From Hollister to Tres Pinos, Aromas, and San Juan Bautista — we have the equipment and local knowledge to execute efficiently.

Do I need a county encroachment permit for driveway tie-ins? +

If work enters the public right-of-way — including driveway approaches, trenching, or traffic control — San Benito County typically requires an encroachment permit. DW Excavation helps you navigate the submittal process and conditions of approval so work can begin without unexpected delays.

What California license classifications cover excavation and grading? +

Excavation is commonly performed under the General Engineering ("A") or Earthwork & Paving ("C-12") CSLB classifications. Hiring a contractor operating under proper classifications protects your project legally and ensures the work meets state standards. DW Excavation holds the appropriate licensing for the scopes we perform.

How does DW Excavation compare to larger regional contractors? +

Larger firms like Don Chapin and Granite Construction offer broad civil capabilities, while smaller local specialists focus on trenching, grading, or septic. DW Excavation blends that capacity with owner-led oversight and clear sequencing — meaning Dallas is personally involved in your project, not just a project manager two levels removed. That translates to faster decisions and fewer delays.

What affects the cost and timeline of excavation in San Benito County? +

The biggest drivers are site access, soil conditions, import/export volumes, utility conflicts, and permit and inspection windows. Our preconstruction review identifies these risks early so we can build realistic budgets and schedules before any equipment is mobilized — protecting you from costly surprises mid-project.

Do you handle grading permits and SWPPP requirements? +

Yes. For significant cut and fill operations, San Benito County requires grading permits, and most earthwork projects require a Stormwater Pollution Prevention Plan (SWPPP). DW Excavation coordinates these requirements alongside your project engineer or can recommend local consultants to ensure your project stays compliant from permit issuance through final inspection.
