Site prep is land clearing with a builder's deadline attached. Your foundation crew has a date, and everything between now and that date is the job: trees down, stumps out, brush cleared, a rough grade pass on the building envelope, and a surface the next trade can actually work on. That's what we deliver. We coordinate directly with your builder or GC so the lot is ready when they need it, not when we get around to it. The owner walks every site before quoting, works from your site plan if you have one, and gives you a firm number.
No spam. We'll call you within 24 hours.
Clearing a lot and prepping a site are not the same job. Clearing gets the trees and brush out of the way. Site prep goes further: stumps ground or pulled below grade so they don't settle under a slab, the building envelope rough-graded to address high spots and fill low areas, and a stable surface left behind that the foundation contractor can drive equipment onto and start working. We're the first crew on site before the grading contractor who dials in the precision grade and before the foundation crew who pours.
Our main tool for site prep clearing is the forestry mulcher, which handles trees up to 12 to 14 inches, grinds stumps a few inches below grade, and leaves a wood-chip surface that compacts well under equipment. The chips also help with moisture control and erosion during the construction window. On a typical residential lot in Summerville, Goose Creek, or Moncks Corner, site prep clearing runs half a day to a full day depending on vegetation density. After clearing, we do a rough blade pass to knock down any significant grade changes. The result is a surface the next trade can actually use.

A crew that only clears trees can hand you a lot that still fails inspection. Site prep is the difference between removing what's on the land and delivering a surface your foundation contractor can actually build on.
We handle both in one trip instead of two separate crews at two separate costs. Trees come down, stumps come out, the rough grade pass happens, and your builder gets one clean handoff instead of coordinating the clearing crew, then waiting, then calling the grading crew.
Building codes in Dorchester, Berkeley, and Charleston counties require the pad to be clear of all organic material, stumps, and roots. Buried stumps decompose and create voids under slabs and footings. We pull or grind them properly the first time so the inspector doesn't send your builder back.
We coordinate directly with your general contractor. If the foundation crew is scheduled for the 15th, we're done before the 15th. Tight timelines are normal for us, and we don't miss them.
All trees, brush, and vegetation removed from the footprint your site plan calls for. We clear to the limits marked on the survey, not past them, and flag anything that needs to stay.
Every stump pulled or ground below grade so nothing is left in the soil to decompose and settle under your slab. This is the step most clearing-only crews skip.
A blade pass after clearing to level out high spots, fill obvious low areas, and leave a surface the foundation contractor can drive equipment onto and start.
Cleared material either mulched on-site (the chips compact well and help with erosion during construction) or hauled off. You and your builder decide during the quote.
Send us the plan before the walk and we'll mark clearing limits, identify preservation trees, and scope the work to your build footprint. We do this for spec builders and custom builds across the Lowcountry.
We talk to your general contractor directly if that's how you want it. Scheduling, access, staging, sequencing: whatever your GC needs communicated, we handle.
Call (854) 300-4979The owner walks the parcel against your site plan or survey, marks the clearing limits, notes trees to preserve, checks the grade, and identifies anything that changes the scope: wet spots, buried debris, access constraints, protected trees.
Mulching head for the vegetation, compact equipment for tight residential lots, and a blade for the rough grade pass. Everything sized to your site, not overpowered for it.
Vegetation comes down, stumps come out below grade, debris is mulched or hauled, and a rough blade pass levels the envelope. One mobilization covers the full scope.
Final walkthrough confirms the surface meets the builder's spec. If anything needs a touch-up, it happens before the trailer loads. Your foundation crew can mobilize the next day.
You've got the lot, the plans, and a builder with a date. We handle the phase between buying the land and breaking ground so your timeline doesn't stall at the start.
You need a stump-free, debris-free, rough-graded surface on your schedule. We deliver to spec and communicate directly with your crew.
A cleared, prepped lot sells for more than an overgrown one. We bring it to a condition where a buyer can see the land and a builder can start.
Site prep costs more than clearing alone because it covers more scope: stumps come out below grade, not just to the surface, and a rough grading pass happens after the vegetation is gone.
What actually drives the price is the vegetation density and tree size, the stump count and how deep they need to go, the existing grade and how much work it takes to level the envelope, the lot size and access, and how the debris gets handled. A mostly-open lot with light clearing and minimal grade work is a different job than a heavily wooded parcel with 30 stumps and a sloped building pad. We quote from your site plan and an on-site walk, never off a satellite image, and the number we give you is the number you pay.
IronJaw walks every site before quoting — from your site plan if you have one, or from a walk of the raw lot. No satellite guesses, no placeholder per-acre number. You get a firm price for your job.

IronJaw Clearing handles pre-construction site prep throughout the Lowcountry — builder lot prep in the Nexton, Cane Bay, and Pine Trace growth corridors around Summerville, infill lots in Charleston and Mt. Pleasant where grand-tree ordinances and tight setbacks shape the scope, waterfront and tidal-adjacent parcels on Johns Island and James Island, and rural homestead and farm-adjacent building pads in Moncks Corner, Walterboro, and Cottageville. Below are the cities we serve most frequently. Don't see yours? Call — if we can reach you, we'll quote you.
"Our builder had a hard start date and IronJaw hit it. Lot was cleared, stumps pulled below grade, and rough graded before the foundation crew showed up. No delays, no surprises on the bill."
"Sent them our site plan ahead of the walk and they marked the clearing limits exactly to it. Owner talked directly with our GC about scheduling. Everything lined up without us being the middleman."
"Wooded lot with a bunch of stumps we were worried about. IronJaw ground everything below grade and left a graded pad our foundation crew could drive straight onto. No burn piles, no mess."
Land clearing, grading, and tree removal in the South Carolina Lowcountry are governed by overlapping state, county, and municipal rules. The biggest one — the SCDES NPDES Construction General Permit — kicks in at one acre of land disturbance statewide. But in the eight coastal counties, sites within ½ mile of a coastal receiving water drop to a 0.5–0.6 acre trigger, and Beaufort County kicks in at just 5,000 sq ft. Below is the working reference IronJaw uses on every quote.
| Jurisdiction | Residential trigger | Commercial trigger | Notes |
|---|---|---|---|
| Charleston County | >5,000 sq ft | >5,000 sq ft | Stormwater permit required before building permit |
| Dorchester County | <1 ac: EPSC + $100; ≥1 ac: full CAA | <0.5 ac: EPSC; ≥0.5 ac: full CAA | Lower commercial threshold than state baseline |
| Berkeley County | ≥0.5 ac: full stormwater | ≥0.5 ac: full stormwater | Manual adopted 2009 |
| Beaufort County | >5,000 sq ft (if zoning permit) | ≥0.5 ac county permit | Within ½ mi of coastal water, ≥0.6 ac → SCDES NOI |
| SCDES statewide | <1 ac: Form 2628 notification; ≥1 ac: NOI + CGP | Same | Fees $125 federal + $100/disturbed acre (max $2,000) |
| Jurisdiction | Grand Tree | Protected Tree |
|---|---|---|
| City of Charleston | ≥24" DBH (excl. pine/sweetgum) | ≥8" DBH — ≥1-acre lots maintain 15 protected/acre |
| Charleston County | ≥24" DBH (excl. pine/sweetgum) | ≥8" DBH — violation fines now $500 per DBH inch |
| Mt. Pleasant | ≥24" (historic) | ≥16" DBH; pine ≥24" — $50 permit fee via OPAL |
| Summerville | (no separate category) | ≥8" DBH — 16"+ goes to monthly Tree Protection Board |
| Dorchester County | ≥24" DBH (excl. pine) | >12" DBH; pine >24" — 1:1 inch replacement ratio |
| Beaufort County | Live Oak/Longleaf 24"; Loblolly/Slash/Shortleaf 36"; other 30" | SFR with existing dwelling can remove non-grand trees (except in buffers) |
| Hilton Head | Specimen live/laurel oak ≥30" | ≥6" DBH (Natural Resources Permit required) |
| Berkeley County | — | No county tree ordinance — NPDES & wetland rules still apply |
Heads up: SCDHEC's environmental functions became SCDES on July 1, 2024 — old permits remain valid; current site is des.sc.gov. Wetlands work additionally requires USACE §404 review and SCDES Coastal Zone Consistency certification. Tidal/marsh alterations need a separate SCDES Critical Area Permit.

Generic clearing advice from national sources misses what actually matters here. The Lowcountry has soils, vegetation, water table, climate, and regulations that shape every job differently than dryland inland work. Here's what IronJaw factors in on every quote.
Lowcountry pads often sit on sandy loam, organic clay, or peat over saturated soils. Standard compaction may not be enough — geotextiles, geogrids, soil replacement, wick drains, or preloading/surcharge are common requirements for commercial work. A geotechnical investigation should precede the bid.
New construction in the City of Charleston SFHA must be 2 ft above Base Flood Elevation (since 7/1/2020), and slab-on-grade is prohibited in the 100-year floodplain (since 1/1/2024). Coastal A Zone rules apply since 1/1/2023. Pad elevations drive significant fill import costs.
A frequent commercial bid omission: who handles dewatering for the high water table. On Lowcountry sites this can be a meaningful scope and cost — clarify in writing whether the GC, site contractor, or specialty subcontractor handles it.
Charleston County requires a stormwater permit for any disturbance >5,000 sq ft, processed separately from the building permit. Stop-work orders frequently hit projects that pulled the building permit but missed the stormwater permit. Plan for both.
A wetland delineation runs $1,500–$3,500; USACE Jurisdictional Determination takes 30–90 days; formal 404/401 permits start at ~$10,000; mitigation credits run $30,000–$60,000/acre. Discovering wetlands mid-project is a budget event — pull the delineation early.
Common questions from homeowners and builders before prepping a lot for construction in the Lowcountry.
Call (854) 300-4979For most residential builds: clearing all trees and brush from the building envelope, grinding or pulling every stump below grade, rough grading the cleared surface, and leaving a stable pad the foundation crew can work on immediately. We work from your site plan and coordinate with your builder to deliver exactly what the next trade needs.
Depends on the lot. Vegetation density, stump count, existing grade, lot size, access, and what finished condition your builder needs all drive the number. A mostly-open lot with light clearing and minimal grade work prices very differently from a wooded parcel with 30 stumps and a sloped building pad. We quote from your site plan and a walk, never off a satellite image.
Ideally 30 to 60 days before your foundation crew mobilizes. That gives disturbed soil time to settle and any required erosion control time to be inspected. If your build schedule is tighter, we can work to it, but the earlier in the timeline you get us on-site, the smoother the handoff.
Yes. Building codes in Dorchester, Berkeley, and Charleston counties require the pad to be clear of all organic material, stumps, and roots. Buried stumps decompose and create voids that cause slabs to crack and footings to settle. Proper site prep is what gets your lot past inspection.
Yes, and we prefer it. Send us the plan before the walk and we'll mark clearing limits, identify preservation trees, and scope the job to your build footprint. We work from site plans and survey plats regularly and coordinate directly with GCs and spec builders.
Half a day to a full day on a typical Summerville, Goose Creek, or Moncks Corner residential lot, depending on vegetation density and how much grade work is needed. Bigger or more complex lots may take longer, and we'll tell you which it is during the walk.
Fully insured. South Carolina doesn't require a trade license for clearing and grading work, so verified insurance is the credential that matters, and we carry it. The owner is on every job.
Every day between now and your foundation date is a day the site needs to be getting ready. Send us your site plan, the owner walks the lot against it, and you get a firm price covering clearing, stump removal, and rough grading in a single mobilization. We work directly with GCs and builders across the Lowcountry, and we call back within 24 hours.
