New Construction Lot Clearing Guide

Building a new home starts with clearing the lot. Whether you are developing a raw wooded parcel or clearing overgrown land for construction, lot clearing is one of the first and most important steps in the building process. Done right, it sets the stage for smooth construction. Done wrong, it creates problems that follow the project from foundation to finish.

I am Keith McDonald, owner of McDonald Tree Service in Billerica, MA. We have been clearing lots for new construction across Middlesex County since 1995. From half-acre house lots in Tewksbury to multi-acre parcels in Carlisle and Concord, we know what it takes to get a building site ready. Here is a complete guide to the process.

What Lot Clearing Involves

Lot clearing for new construction typically includes:

• Tree removal: Cutting down all trees within the building footprint, driveway, septic area, and grading zones. This includes felling, limbing, chipping brush, and removing trunk wood.
• Stump removal: Grinding or excavating stumps below grade so they do not interfere with foundation work, utility trenching, or grading.
• Brush and undergrowth clearing: Removing shrubs, invasive species, vines, and ground-level vegetation.
• Debris removal: Hauling away all wood chips, logs, and vegetative debris, or processing them on-site.
• Selective preservation: Protecting trees the homeowner or town regulations require to be kept, using fencing, root zone protection, and careful equipment routing.

Lot clearing does not typically include grading, excavation, or earthwork. Those are separate phases handled by the excavation contractor after the trees and stumps are out.

Lot Clearing Cost in Massachusetts

Lot clearing costs vary significantly based on the size of the area, the density and size of the trees, access, and disposal requirements. Here are general ranges for our service area:

• Lightly wooded half-acre lot: $3,000 to $6,000. Scattered trees with open understory, good access for equipment.
• Moderately wooded half-acre lot: $6,000 to $12,000. Mix of hardwoods and softwoods, moderate undergrowth, typical suburban lot.
• Heavily wooded half-acre lot: $10,000 to $18,000. Dense forest, large hardwoods, heavy brush, difficult access.
• Full acre or larger: $15,000 to $35,000+. Scale jobs with significant timber volume. Costs per acre decrease as the total area increases due to equipment efficiency.

These ranges include tree removal, stump grinding, brush chipping, and debris removal. They do not include permits, wetland consultant fees, or erosion control materials, which are additional costs. For a more detailed pricing breakdown, read our guide on lot clearing cost in Massachusetts.

Permits and Regulations

New construction lot clearing in Massachusetts requires permits at multiple levels. This is not optional work you can do on a Saturday with a chainsaw and a pickup truck.

Building Permit and Site Plan

Your building permit application includes a site plan that shows the building footprint, driveway, septic system, well location, and the area to be cleared. The clearing should match the approved site plan. Clearing beyond the approved limits can result in stop-work orders and fines.

Tree Removal Permits

Several towns in our service area have tree preservation bylaws that apply even when you have a building permit. Lexington requires permits for removing trees over 12 inches in diameter. Concord and Lincoln have strict vegetation management requirements. Bedford has Planning Board conditions that may require tree preservation plans. Check your town's requirements before the first tree comes down. For a complete town-by-town breakdown, see our Massachusetts Tree Removal Permits Guide.

Wetland Buffer Zones

If any part of your lot is within 100 feet of a wetland, stream, or other resource area, you need Conservation Commission approval before clearing. This is extremely common on undeveloped parcels in Carlisle, Westford, Concord, and Lincoln, where many buildable lots border wetlands. The Conservation Commission may limit the area you can clear, require buffer plantings, and mandate erosion controls throughout construction.

Erosion and Sediment Control

Massachusetts stormwater regulations require erosion and sediment controls on any land disturbance over 1 acre, and many towns require them for smaller areas. Silt fencing, hay bales, stabilized construction entrances, and sediment basins must be in place before clearing begins and maintained throughout construction.

The Lot Clearing Process: Step by Step

Here is how we approach a typical lot clearing project:

1. Site walk and assessment. We walk the property with the homeowner and builder, review the site plan, identify trees to be removed and trees to be preserved, locate wetland boundaries, and assess access points for equipment.
2. Tree preservation setup. Before any cutting starts, we install protective fencing around trees that are being kept. The fence goes at the drip line, not at the trunk. Heavy equipment driving over root zones kills trees, sometimes years after the damage occurs.
3. Erosion control installation. Silt fencing and other erosion controls go in before the first tree comes down, especially near wetlands, slopes, and drainage paths.
4. Brush clearing. We start with undergrowth and small trees, working from the edges of the clearing area toward the center. This creates working space for the larger tree removals.
5. Tree felling and processing. Large trees are felled directionally into the clearing area. Limbs are chipped on-site with our industrial chipper. Trunk wood is cut to length and either removed or left for the homeowner if they want firewood.
6. Stump grinding. All stumps within the building area, driveway, and septic field are ground 6 to 12 inches below grade. Stumps outside the construction zone can be ground flush or left, depending on the plan.
7. Final cleanup. Chips, debris, and loose material are removed or spread as specified. The site is left ready for the excavation contractor to begin earthwork.

Timeline: How Long Does Lot Clearing Take?

For a typical half-acre residential lot, expect:

• Permitting: 2 to 8 weeks, depending on whether Conservation Commission approval is needed.
• Clearing work: 2 to 5 days for a half-acre lot. Larger or more heavily wooded parcels take proportionally longer.
• Stump grinding: Usually completed the same week as clearing, often the same day for smaller lots.

The biggest delay is almost always permitting, not the physical work. Start the permit process early so clearing is not the bottleneck that delays your construction schedule.

Trees to Preserve: What to Keep

Not every tree on the lot needs to come down. Strategic tree preservation adds immediate value to a new home and satisfies town requirements. Here is what we recommend keeping when possible:

• Mature hardwoods outside the building zone. A 60-year-old red oak in the future backyard is worth thousands in property value and decades of shade. Protect it.
• Buffer trees along property lines. Leaving a row of trees between the new house and the neighbors provides privacy and reduces visual impact.
• Trees required by the town. Some permits come with conditions specifying minimum tree retention. Know these before you start.

The key to successful tree preservation during construction is protecting the root zone. A tree's critical roots extend well beyond the drip line. Compaction from heavy equipment, grade changes, and root cutting during utility trenching are the three biggest killers of preserved trees on construction sites.

Common Mistakes in Lot Clearing

• Clearing before permits are finalized. We have seen projects shut down because the owner started clearing before the building permit was issued. Always wait for permits.
• Over-clearing. Clearing more than the approved area triggers enforcement action and may require replanting. Stick to the site plan.
• Ignoring the trees you are keeping. Preserved trees that are not properly protected during construction often die within 3 to 5 years from root damage and soil compaction.
• Not coordinating with the builder. The tree crew and the excavation contractor need to be on the same page about access, staging, and the final grade plan.
