Lot Clearing Before Building in Pennsylvania — What You Need to Know
Clearing a lot for a new home, addition, or accessory structure is more involved than simply cutting down trees. Pennsylvania has specific permitting requirements for earth disturbance, and skipping the permit process can stop your construction project dead. This guide walks through the complete process of lot clearing before building in the Lehigh Valley.
Step 1: Know What Permits You Need Before Clearing Anything
Erosion and Sedimentation (E&S) Permit
Pennsylvania’s Clean Streams Law requires an Erosion and Sedimentation Control Plan for any earth disturbance of 5,000 square feet (approximately 0.11 acre) or more. This includes clearing that disturbs soil — which tree removal and stump extraction does. The E&S plan must be prepared by a licensed professional and submitted to the County Conservation District before work begins:
- Lehigh County Conservation District: (610) 391-9583
- Northampton County Conservation District: (610) 746-1971
Plan preparation typically costs $500–$2,000 for residential-scale projects. Review and approval typically takes 2–4 weeks.
Municipal Grading / Land Disturbance Permit
Most Lehigh Valley townships and boroughs require a grading or land disturbance permit from the municipal building department for lot clearing associated with a new construction project. This is separate from the County E&S permit. Contact your specific municipality’s building or zoning department for requirements and fees.
Tree Permits
In Allentown, Bethlehem, and Easton, removing trees on private property that meet protected size thresholds requires permits even for construction-related clearing. Get clarity on permit requirements before scheduling clearing — municipalities can stop construction for unpermitted tree removal.
Wetland and Floodplain Review
If any portion of your lot is within a FEMA Special Flood Hazard Area or contains wetland features (persistent wet areas, hydric soils, wetland vegetation), additional state and federal review is required before clearing. Pennsylvania DEP and the Army Corps of Engineers both have jurisdiction over wetland impacts. Do not clear these areas without permits — violations can result in significant fines and mandatory restoration requirements.
Step 2: What to Keep vs. Remove
Not every tree on a construction site needs to come down. Mature trees that can be preserved add real market value to a finished property — studies consistently show mature trees increase residential property values by 10–15%. Before scheduling clearing:
- Identify trees that are clearly outside the building envelope, grading limits, and utility trench paths — these may be preservable
- Have an arborist flag trees worth preserving vs. trees that are poor candidates (poor structure, disease, invasive species)
- Consider construction protection for trees being preserved — root zone fencing at the drip line prevents construction equipment compaction damage to the root system during building
Step 3: Full Stump Removal Is Required for Construction Sites
Stump grinding — which leaves the root mass below grade — is not sufficient for a construction building site. As buried organic material (stumps and roots) decays, it creates voids that cause settlement. Foundations, slabs, driveways, and compacted subgrades laid over decaying root masses will eventually settle unevenly — cracks, dips, and structural problems that are expensive to repair after the fact.
For building sites: all stumps and major lateral roots within the building footprint, driveway, and any compacted area must be fully excavated with an excavator, not ground. The excavated voids are backfilled with clean structural fill (not organic material) and compacted in lifts per engineering specifications.
Step 4: Site Clearing Methods and Equipment
Conventional Tree Removal + Excavation
Chainsaw crews fell trees, cut logs to manageable lengths, chip brush, and haul or burn material. An excavator then extracts stumps and root balls. Most cost-effective for sites with a mix of large trees and open areas.
Forestry Mulcher
A skid steer or tracked machine with a forestry mulching head can clear brush and small trees (up to 4–6 inch diameter) quickly, reducing everything to mulch chips in a single pass. Much faster than conventional hand clearing for dense brush. Not suitable for large-diameter trees or stumps.
Excavator-Only Clearing
For heavily wooded sites, an excavator can push over, pick up, and pile trees for burning or chipping. Faster for bulk clearing but rougher on remaining trees and the site surface. Requires adequate excavator access.
Step 5: Soil Stockpiling and Topsoil Management
During clearing, preserve your topsoil. Topsoil — the dark, organic upper 6–12 inches of soil — is valuable for site restoration after construction. Standard practice:
- Strip and stockpile topsoil before any grading begins
- Keep topsoil stockpile separate from subsoil and spoil material
- Protect stockpile with silt fencing to prevent runoff (required by E&S permit)
- Re-spread topsoil over finished grades before seeding or landscaping

| Material disposal or on-site chipping | $500–$2,000 |
FAQs — Lot Clearing Before Building PA
Do I need an arborist or can any tree service do lot clearing?
Any licensed tree service can handle the clearing work. However, for sites where you want to preserve specific trees, an arborist’s guidance on tree selection and construction protection planning is valuable. Also confirm the contractor understands E&S compliance — they should not clear without confirmed permits in place.
How far in advance should I schedule lot clearing before construction?
Allow 4–8 weeks for permits plus the clearing schedule. For spring construction starts, begin the permit process in winter. Clearing in late fall or winter also has the advantage of easier equipment access on frozen ground.
