What excavation costs in Lancaster and the Antelope Valley
Excavation in the Antelope Valley runs $175 to $300 an hour for a machine with an operator, and the common projects have honest ranges: a building or manufactured home pad $3,000 to $9,000, a conventional septic system $10,000 to $20,000 installed, utility trenches $20 to $60 per foot, lot clearing $1,500 to $5,000 an acre and a pool dig $2,000 to $7,500. What moves a job inside its range is nearly always one of three things: the ground (sand, caliche or granite), the access that decides which machine fits and where the excavated dirt ends up. The table below is the one licensed local contractors quote inside.
Poppy Excavation publishes this table so you can budget a lot before you buy it and read any contractor's quote line by line. Nothing here is a quote from us; the written number comes from the licensed contractor we refer, after a site walk.

Ranges reflect residential and small commercial work across Lancaster, Palmdale and the unincorporated Antelope Valley in both Los Angeles and Kern counties. A site walk by the referred contractor turns your project into an exact written number.
The three questions that price any dig here
What is the ground? The valley floor is mostly sand and sandy loam that digs fast and percs well. Two to four feet down on much of the east side sits caliche, a calcium carbonate hardpan that behaves like weak concrete and adds a third or more to trench and leach field hours. The foothills in Acton, Agua Dulce, Leona Valley and south Palmdale are decomposed granite over bedrock with boulders, which is breaker and sometimes drilling work. A probe bar and a test hole on the site walk cost nothing and settle this before the quote.
How is the access? Open acreage in Antelope Acres or Rosamond lets a full-size excavator drive straight to the pad and finish in a day. A fenced tract lot in Rancho Vista or west Lancaster means a compact machine through a side gate and three times the passes. Sloped lots change the machine again and add compaction testing to the bill.
Where does the dirt go? Soil swells about a quarter when excavated, and a modest pad or pool produces fifteen to thirty truckloads. Spread on your own acreage it costs nothing. Hauled to the landfill it costs $150 to $350 a load. This single question is why the instant estimator on the homepage asks about your lot type before anything else.
Septic: the perc test prices the system
Nearly every lot outside the Lancaster and Palmdale sewer districts is on an onsite wastewater treatment system, and the price of that system is decided by a percolation test before a shovel moves. Los Angeles County Public Health publishes its OWTS requirements and procedures for unincorporated LA County, and Kern County Environmental Health runs its own local program for Rosamond and California City. Fast sand means short leach lines and a conventional system. Slow caliche or clay means seepage pits or an engineered system that can nearly double the number. The septic site work page walks through the whole flow.
Permits and fees you should expect
Grading permits follow the California Building Code grading appendix, which LA County enforces through its grading guidelines. In broad strokes, moving more than 50 cubic yards, cutting more than a few feet, filling more than a foot or changing a drainage course needs a permit, so a building pad almost always does and a shallow trench usually does not. The City of Lancaster and the City of Palmdale issue their own; unincorporated lots go through the LA County Antelope Valley field office or Kern County. Permit fees scale with cubic yards and plan check and typically land between a few hundred dollars for a pad and a few thousand for a hillside cut with engineering. The referred contractor pulls the permit and shows the fee as its own line. The permits page lists who issues what, town by town.
How to read a contractor's quote against this table
- 1
Find the mobilization line
It should be there and it should be $250 to $700 depending on how far the yard is from your lot. A quote with no mobilization line has hidden it somewhere else.
- 2
Match each job to a row
A pad, a septic system, a trench and a driveway are four rows, not one lump. If the quote is one number, ask for it broken out. A good contractor already has it that way.
- 3
Look for the rock or caliche allowance
On the east valley and the foothills, a stated allowance for hard digging is a sign the contractor walked the lot. No allowance usually means a change order later.
- 4
Check who pays for the dirt leaving
Spoil export should be a per-load number times an estimated count. If it is missing and your lot has nowhere to spread dirt, the quote is light.
- 5
Confirm permits and 811 are included
The permit fee, the compaction testing and the DigAlert ticket should all appear, even if the fee is an estimate. Then verify the license number at cslb.ca.gov.
Cost questions we hear most
Why do excavation quotes vary so much for the same lot?
Because most quotes are one number covering machine time, trucking, disposal fees and risk padding without saying which is which. The table above prices the pieces separately, so any quote you collect can be broken down against it and compared honestly.
What is the biggest cost surprise on Antelope Valley digs?
Caliche. The cemented hardpan layer two to four feet down on much of the east valley from Lancaster to Lake Los Angeles turns a sandy trench into breaker work, and a leach field quoted off the plan can grow by a third. A test hole on the site walk settles it before the number goes on paper.
Does the perc test really change the septic price that much?
Yes. A fast perc rate means short leach lines and a conventional system at $10,000 to $20,000 installed. A slow rate forces seepage pits or an engineered system at $18,000 to $35,000. The test itself is $1,200 to $3,000 and it is the best money in the whole project.
Does the 811 requirement delay my job?
California law requires a free DigAlert ticket at least two working days before excavation, so a dig booked today legally starts no sooner than the marks allow. The referred contractor files it on every job as routine and the lead time disappears into normal scheduling.
Are these prices a quote from Poppy Excavation?
No. Poppy Excavation is a referral service and does not hold a contractor license or quote work. These are the ranges that licensed Antelope Valley excavation contractors quote inside for residential and small commercial jobs. The written quote comes from the contractor we refer, on their paper.
