Land Clearing Cost Per Acre
In The East Bay (2026)
Light clearing runs $1,200-$2,500 an acre. Heavy clearing runs $4,500-$8,000. Here is exactly what pushes a Contra Costa hillside from one tier to the other · and what defensible space work actually costs every year.
Land clearing cost per acre in the East Bay runs from about $1,200 for light grassland to $8,000 for heavy timbered hillside, and the spread is not marketing padding · it is the difference between mowing a flat field and pulling forty mature trees off a 25% slope in Orinda. Most quotes you see online are national averages built on Texas ranch land. That is not what you own. This guide gives you the working ranges we price against in Contra Costa County, the specific site conditions that move you between tiers, and the permit and timing traps that catch people who start cutting before they call anyone.

Land Clearing Cost Per Acre · The Tables
Three tiers cover almost every residential and small-commercial job in the East Bay. Find the one that matches what you’re standing on.
| Clearing Tier | Cost Per Acre | What It Looks Like |
|---|---|---|
| Light | $1,200 to $2,500 | Grass, weeds, scattered brush, a few small trees. Machine drives straight across it. |
| Moderate | $2,500 to $4,500 | Dense brush, saplings, 10-20 trees per acre, some slope, stumps to grind. |
| Heavy | $4,500 to $8,000 | Mature trees, heavy undergrowth, steep or rocky ground, tight access, stump removal. |
Individual line items get priced separately when the job isn’t a full-acre sweep:
| Line Item | Typical Range | Notes |
|---|---|---|
| Brush clearing only | $800 to $3,000 / acre | No trees, no stumps. Blackberry and coyote brush are the East Bay standards. |
| Forestry mulching | $500 to $1,000+ / acre | Material stays on site as chip. No haul cost, no dump fee. |
| Tree removal | $400 to $1,200 each | Height, trunk diameter, drop zone and proximity to structures. |
| Stump grinding | $100 to $400 each | Diameter and root spread. Full excavation of the root ball costs more. |
| Grading after clearing | $0.08 to $2.00 / sq ft | Or $40-$180/hr. See our grading and leveling service. |
| Excavation / soil export | $60 to $200 / cubic yard | Only if you’re cutting into the hill, not just removing vegetation. |
Nobody can price an acre from a satellite photo. Slope, access width and what’s actually growing under the canopy move these numbers more than acreage does. Every number above is a working range · your written figure comes after we walk the parcel.
What Decides Which Tier You Land In
Acreage is the least important variable on this list. Seven things decide your tier:
- Vegetation density. An acre of annual grass is one pass with a mower deck. An acre of ten-year-old Himalayan blackberry is a masticator working at a crawl, and it can take four times as long.
- Tree size and species. A 6-inch acacia and a 30-inch live oak are not the same job. Oak and bay are dense, heavy and slow to process. Eucalyptus is tall, brittle and drops unpredictably. Species changes both the felling method and the disposal weight.
- Slope. Past roughly 20-25%, wheeled equipment stops being an option and tracked machines slow down. Steep ground also means erosion control obligations after you strip the cover off.
- Rock. Contra Costa hillsides hide sandstone and serpentine. Rock doesn’t affect mowing, but it destroys stump grinding productivity and can stop root-ball excavation cold.
- Access. If a 12-foot machine can’t get through the gate, we’re clearing with smaller equipment or carrying material out by hand. This is the single biggest price swing on El Sobrante and Richmond Hills lots · the same acre can double based on driveway width and turning room alone.
- Chip on site or haul off. Leaving mulched material on the ground is the cheapest outcome. Loading it into trucks and paying tip fees is the most expensive.
- Whether stumps come out. Cut flush and leave the stump: cheap. Grind to 8 inches below grade: moderate. Excavate the entire root ball because you’re pouring a foundation over it: expensive, and it turns a clearing job into an excavation job.
On hillside parcels, we quote access before we quote acreage. A half-acre with a 14-foot side yard and a turnaround usually prices below a quarter-acre you can only reach with a wheelbarrow.
Defensible Space And Fire Hazard Clearing
This is the clearing work most East Bay property owners actually need, and it is the one thing on this page that is not a one-time project. If your property sits in the wildland-urban interface · the hills above El Sobrante, the ridgelines around Orinda, Lafayette and Moraga, the canyon lots throughout Richmond Hills · defensible space is recurring annual compliance work, not a job you finish.
The concept is straightforward: create zones of managed vegetation around structures so a fire approaching your house loses fuel before it reaches the walls, and so firefighters have somewhere safe to stand and defend it. The immediate zone closest to the structure is kept essentially free of combustible material. Moving outward, you thin and space vegetation, break up continuous fuel, limb up trees so ground fire can’t ladder into the canopy, and clear dead material and ground litter.
In practice on an East Bay hillside that means cutting back the blackberry and coyote brush that regrows every wet season, removing dead limbs and standing dead trees, thinning eucalyptus and acacia stands, mowing annual grasses before they cure in early summer, and clearing leaf litter and needle cast off roofs, decks and the ground near the structure.
Clearing to standard once does not keep you cleared. Coastal-influenced East Bay hillsides regrow fast · a parcel cleared to bare ground in March can be waist-high in grass and re-sprouted brush by June. Fire agencies inspect during the season, and a compliant parcel in April can fail in July. Owners in high-hazard areas should budget for a full clear plus at least one maintenance pass every year.
Budget-wise, defensible space work usually prices at the brush and light-to-moderate tiers · $800-$3,000 per acre for a brush-and-grass pass, moving into the $2,500-$4,500 moderate tier when there’s real tree work, dead-wood removal or limbing involved. Because the material is vegetation rather than structure, forestry mulching is frequently the right tool: it kills the fuel, leaves a mulch layer that suppresses regrowth, and skips the haul-off entirely.
Fire hazard severity mapping, inspection schedules and specific clearance requirements vary by agency and by jurisdiction, and they get updated. Before you plan a defensible space program, confirm the current requirements with your local fire district or fire department for your exact parcel. What we can tell you is what the work costs and how long it takes on ground like yours.
Three Different Jobs People Call “Clearing”
Three different objectives, three different scopes, three different prices. Getting these confused is the most common reason a quote comes back higher than someone expected.
Clearing for defensible space
Goal: reduce fuel. You are not trying to get to bare dirt. Healthy, spaced, well-maintained trees usually stay. Stumps can be cut flush and left. Chipped material spread on the ground is often desirable. This is the cheapest of the three, and it’s recurring.
Clearing for construction
Goal: a buildable pad. Everything organic comes out, including root balls, because you cannot pour a foundation or compact a pad over decomposing wood. Stumps get excavated, not ground. Topsoil and organics are usually stripped and exported. This runs at the top of the moderate tier or into heavy, and it flows directly into grading and pad prep · see also our ADU site prep package, which bundles clearing, slab removal and grading.
Clearing for a lot sale
Goal: make the parcel legible. A buyer needs to see the topography, the property lines, the access route and whether there’s a flat spot worth building on. You’re clearing sight lines and undergrowth, not creating a pad. Usually light-to-moderate, and it pays for itself in appraisal and offer quality more reliably than almost any other pre-sale spend.

Get My Free EstimateForestry Mulching vs. Haul-Off
Forestry mulching runs a rotary or drum masticator over standing vegetation and grinds it into chip that stays on the ground. At $500-$1,000+ per acre, it is the cheapest clearing method available, and the reason is simple: there is no loading, no trucking and no tipping fee. The material never leaves.
Haul-off means cutting, loading, trucking and paying disposal by the ton. It costs more · often two to four times more once you add trucks and tip fees · but you end up with clean ground.
| Forestry Mulching | Cut & Haul Off | |
|---|---|---|
| Cost | $500 to $1,000+/acre | Roughly 2-4× mulching, driven by tonnage and haul distance |
| Appearance | Rough chip layer, brown, uneven | Clean ground, ready to grade or seed |
| Erosion | Chip layer protects soil on slopes | Bare soil · needs erosion control |
| Regrowth | Mulch suppresses it for a season or two | Regrows faster unless treated |
| Best for | Defensible space, lot sale, fuel reduction | Construction pads, anything you’re building on |
| Not suitable when | You need a compactable pad | Budget is the constraint and appearance isn’t |
The trade-off in one sentence: mulching is cheaper and better for the soil, haul-off looks better and is the only option if anything is getting built. Plenty of jobs use both · mulch the back slope, haul off the building footprint. If you do need material moved, our debris hauling and recycling crew handles the trucking and the documentation.
Why Clearing Debris Doesn’t Count Toward Your 65%
California requires a minimum 65% diversion of non-hazardous construction and demolition waste, and unincorporated Contra Costa County requires a Waste Management Plan before the permit issues plus a Waste Management Report with receipts after completion. As of August 4, 2025 those plans and reports run through the Green Halo portal.
Excavated soil and land-clearing debris are excluded from the diversion calculation. Green waste and dirt do not help your 65%. If your project involves both clearing and building demolition, only the demolition materials · concrete, wood, metal, drywall, roofing · count toward the number you have to hit.
Two practical consequences. First, do not build a diversion plan that leans on your green waste volume; it won’t count and your report will come up short at final. Second, a pure land-clearing job with no structure involved generally isn’t generating C&D diversion paperwork at all · but green waste still has to go to a facility that takes it and dirt still has to go somewhere legal. It just isn’t part of the 65% math. More on how the reporting works in our Contra Costa demolition permit guide.
Permits, Tree Rules And Grading Thresholds
Clearing vegetation feels like it shouldn’t need permission. Sometimes it doesn’t. Often it does. Four things to check before a saw touches a trunk.
Tree protection and removal rules
Confirm before you cut. Tree protection ordinances, heritage and protected tree designations, permit requirements and replacement obligations vary significantly between unincorporated Contra Costa County and each individual city, and they change. Some jurisdictions regulate by trunk diameter, some by species, some by location on the lot, some by whether the work is tied to a development application. A tree protection plan may be a required component of your permit package. There is no single rule that covers the East Bay, and cutting first and asking later is how people end up with fines and replacement planting requirements. Call the planning department for the jurisdiction the parcel actually sits in · for El Sobrante that is the County, not a city.
Grading permits
If clearing turns into earthmoving, Contra Costa’s grading thresholds apply: a grading permit is required for excavation deeper than 5 feet or more than 200 cubic yards, and for fill that supports a structure, is deeper than 3 feet, or exceeds 200 cubic yards. Lafayette, Moraga and Orinda drop that threshold to 50 cubic yards. Grading of 1,000 cubic yards or more triggers neighbor notification. Permit submittals require three sets of plans stamped by a licensed California Civil Engineer or Architect plus two copies of a geotechnical report.
Stormwater
Disturbing more than one acre brings a SWPPP and a Notice of Intent into the picture. That is a real document set with real cost, and it should be in the budget from day one rather than discovered mid-job.
Erosion control
Strip vegetation off a Contra Costa slope and you have created an erosion problem that shows up with the first real rain. Fiber rolls, silt fence, straw wattles, hydroseed or a retained mulch layer are cheap compared to the alternative · and on slopes they are frequently a permit condition rather than a suggestion.
When To Clear · The Seasonal Calendar
Timing is worth real money on this work.
- Clear before fire season, not during it. Late winter through late spring is the window. The ground is firm enough for equipment, grasses haven’t cured yet, and you’re compliant before inspections start. Wait until July and you’re competing for crews with everyone else who waited.
- Avoid the wet season on slopes. Saturated hillside soil means equipment ruts, compaction damage, spun-out tracks and sediment running off your lot. Contra Costa hillsides in February are a genuinely bad place to run a machine, and the cleanup can cost more than waiting would have.
- Nesting bird timing. Tree and heavy brush removal during nesting season carries real regulatory exposure · active nests of most native bird species are federally and state protected, and the practical result is that vegetation removal in roughly the February-through-August window may require a nesting bird survey by a qualified biologist before work starts. Scheduling tree work outside that window avoids the survey cost and the delay entirely. On larger or permitted projects this is often a written condition of approval.
- Build the pad in the dry. If clearing feeds directly into grading and foundation work, target late spring through early fall so the compaction and the pour aren’t fighting weather.
Worked Example: Half-Acre El Sobrante Hillside
Here is a realistic composite job so you can see how the ranges assemble into a number. Half-acre parcel above Appian Way, roughly 18% average slope, heavy blackberry across the lower two-thirds, twelve trees between 8 and 20 inches, four of them dead. Access is a 12-foot driveway with a tight turn. Owner wants defensible space compliance and a usable flat area near the house.
| Scope Item | Basis | Working Range |
|---|---|---|
| Brush + grass clearing (0.5 acre, moderate tier) | $2,500-$4,500/acre × 0.5 | $1,250 to $2,250 |
| Tree removal · 4 dead, 3 thinned (7 total) | $400-$1,200 each | $2,800 to $8,400 |
| Stump grinding · 7 stumps | $100-$400 each | $700 to $2,800 |
| Forestry mulching, lower slope | $500-$1,000+/acre × 0.3 | $150 to $300 |
| Haul-off, pad area only | Partial load | $300 to $700 |
| Erosion control on cleared slope | Wattles, seed | $400 to $1,200 |
| Light grading, flat area near house | $40-$180/hr | $500 to $1,500 |
| Composite range | $6,100 to $17,150 |
That spread is wide on purpose, and it shows you where the leverage is. Tree count and tree size dominate this job · the vegetation clearing itself is under $2,300, while the trees and stumps are potentially $11,000. Cut the tree scope from seven to three and the top of the range drops by roughly $6,000. This is exactly the conversation worth having on the site walk: which trees genuinely have to come out for fire safety or construction, and which ones you’re removing out of habit.
Note also that no grading permit is triggered here · nobody is moving 200 cubic yards or cutting 5 feet deep · and at half an acre no SWPPP applies. Cross either line and the picture changes.
Frequently Asked Questions
How much does it cost to clear an acre of land in the East Bay?
Light clearing runs $1,200-$2,500 per acre, moderate $2,500-$4,500, and heavy $4,500-$8,000. Brush-only work is $800-$3,000 per acre and forestry mulching starts around $500-$1,000+ per acre. Contra Costa hillside parcels usually land in moderate or heavy because of slope and access, not because of how much is growing.
Is forestry mulching cheaper than hauling material away?
Considerably. Mulching at $500-$1,000+ per acre avoids loading, trucking and tipping fees entirely because the material stays on site as chip. Haul-off typically runs two to four times more. The trade-off is appearance and function: mulching leaves a rough brown chip layer that protects slopes from erosion, while haul-off leaves clean ground you can grade and build on.
Do I need a permit to clear land or remove trees in Contra Costa County?
It depends on what you’re removing and where. Tree protection and removal rules vary by jurisdiction and change over time, so always confirm with the planning department that covers your parcel before cutting · for El Sobrante that’s unincorporated Contra Costa County. Separately, a grading permit is required for excavation deeper than 5 feet or over 200 cubic yards (50 cubic yards in Lafayette, Moraga and Orinda), and disturbing more than an acre brings a SWPPP and Notice of Intent.
Does land clearing debris count toward the 65% recycling requirement?
No. Excavated soil and land-clearing debris are excluded from the CALGreen diversion calculation. Only construction and demolition materials count. If your project includes both clearing and structure demolition, plan your 65% around the concrete, wood, metal and drywall · green waste and dirt won’t help you hit the number.
How often does defensible space clearing need to be redone?
Plan on annual work in the wildland-urban interface, and often a full clear plus one maintenance pass per year. East Bay hillsides regrow fast · a parcel cleared to bare ground in March can be waist-high by June. Requirements and inspection schedules vary by fire agency, so confirm the current standard for your address with your local fire district.
What is the best time of year to clear land in the East Bay?
Late winter through late spring. The ground is firm enough for equipment, grasses haven’t cured, and you’re compliant before fire season inspections begin. Avoid running machines on saturated slopes in the wet season, and schedule tree work outside the roughly February-to-August nesting bird window to avoid needing a biological survey before you start.
