A Great Build Starts Below the Surface
Every foundation, driveway and slab is only as good as the ground under it. Poor site prep shows up later as settling, cracked concrete, standing water and wet crawlspaces. Getting it right at the start costs far less than fixing it after.
What is site preparation?
Site preparation is the work that turns raw land into a stable, level, well-drained surface ready for construction. It typically includes clearing, topsoil stripping, excavation and fill, grading, compaction, drainage and utility trenching.
Whatcom Excavation handles the full scope with one local crew, so there’s no juggling separate clearing, grading and drainage contractors. You get one plan, one price and one team accountable for the result.

What Our Site Prep Includes
Every lot is different, so we build the scope around your property and your plans. Most projects include some or all of the following.
01
Site Evaluation & Layout
We walk the property, review your plans, check access, slope and soil, and confirm where the house, driveway and drainage will go.
02
Clearing & Grubbing
Removal of trees, brush, stumps and roots from the build area, with debris hauled off or processed on site.
03
Topsoil Stripping
Organic topsoil is stripped and stockpiled for later landscaping, so it isn’t left under your foundation.
04
Excavation, Cut & Fill
We cut high spots and fill low ones to bring the site to the right elevations for your plan.
05
Grading & Building Pads
Rough and finish grading, plus level, accurately set pads for homes, shops, ADUs and slabs.
06
Compaction
Structural fill and base rock placed in lifts and compacted, so the ground doesn’t settle under your build.
07
Drainage & Utility Trenching
Footing drains, French drains, stormwater lines and trenches for water, power and sewer.
08
Erosion & Sediment Control
Silt fencing, rock construction entrances and soil stabilization to keep mud on your site and out of ditches and streams.
09
Access Roads & Driveways
A solid construction entrance and driveway base so trucks and trades can reach the site in any weather.
Site Prep for Every Kind of Project
From a single ADU pad in Bellingham to acreage in the county, we size the crew and machines to the job.
New Homes
Clearing, pads, footing drains and utilities for custom and spec homes.
ADUs & Additions
Careful work on tight lots next to existing homes, driveways and utilities.
Shops, Garages & Barns
Level, compacted pads for pole buildings, shops and detached garages.
Rural Acreage
Access roads, homesites and drainage on larger rural properties.
Site Prep Built for Whatcom County Conditions
Our region’s long rainy season, high water tables and dense glacial soils make site prep here different. Water that isn’t managed at the start ends up in your crawlspace, under your slab or across your neighbor’s yard.
We plan drainage first, use the right base materials for wet ground and schedule compaction and final grading around the weather, so your site holds up long after the build is done.
Drainage First
Water is routed away from the build before anything goes in the ground.
Proper Base
Geotextile fabric and compacted rock where native soils are soft.
Erosion Control
Sediment kept on site to protect streams, ditches and neighbors.
Permit-Aware
We help you understand clearing and grading permit needs up front.

What Affects the Cost of Site Prep?
No two lots are the same, which is why we price every project after seeing it in person. These are the biggest factors that shape your estimate.
Our estimates are free, written and itemized, so you can see exactly where your budget goes.
Lot Size
The area that needs clearing, grading and compaction.
Trees & Vegetation
How much timber, brush and stumps need removing.
Slope & Terrain
Steep or uneven ground means more cut, fill and care.
Soil Conditions
Soft, wet or rocky soils may need over-excavation or imported fill.
Site Access
Tight or remote sites can affect equipment and trucking.
Drainage Needs
Footing drains, French drains and stormwater systems.
Haul-Off & Fill
Material exported off site or imported rock and structural fill.
Permits

Site preparation covers everything that gets raw land ready to build on: clearing and grubbing, stripping topsoil, cut and fill, grading, building pads, compaction, drainage, utility trenching, erosion control and access roads or driveways. We tailor the scope to your lot and your build.
Many residential lots take from a few days to a couple of weeks, depending on lot size, how much clearing is needed, the amount of earth moved and the weather. We'll give you a realistic timeline with your estimate.
Often, yes. Requirements depend on how much area is disturbed, how much material is moved, and whether the site is near critical areas such as wetlands or streams. We'll walk you through what typically applies, and you can confirm with Whatcom County Planning & Development Services or your city.
Cost depends on lot size, vegetation, slope, soil conditions, access, drainage needs, haul-off or import of material, and permits. Because every lot is different, we provide a free on-site estimate with a clear written scope and price.
Yes. We plan wet-season work with erosion and sediment control, stabilized access and the right methods for saturated soils. Some steps, like final grading and compaction, are best scheduled around the weather, and we'll plan for that.
