What We Do: Excavation and Site Prep

Land Clearing

Land Clearing and Site Prep in Bellingham by Agate Northwest
Prior to any raw land development, the site must be prepared for construction. This may include permitting, erosion control, harvesting the timber (if any) for maximum value, stump removal, stripping topsoil for later use or removal, water runoff mitigation including drainage ditches, and onsite access including culverts and rough driveway construction. Each building site has its own unique characteristics, so we make a complete assessment based on your end goals, local rules and regulations.

Subsurface challenges can be the largest unknown in any construction project, so we provide routine updates and offer logical, cost effective solutions to any problems that pop-up along the way. Trust Agate NorthWest to get your job done right.


  • Permitting
  • Erosion control and inspections
  • Tree and stump removal
  • Topsoil removal
  • Water runoff mitigation
  • Culverts and rough driveways

Surface Grading

Surface Grading in Bellingham by Agate Northwest

The final construction process usually includes final grading around newly built structures. This may include backfilling around foundations, bringing in screened topsoil, and smoothing the topsoil to the proper elevation.

Final grading considerations are made with natural water flow in mind, so any rain water is diverted away from buildings and into water catchment structures such as road ditches, catch basins or storm sewers.


  • Backfilling around foundations

  • Utilizing onsite topsoil or bringing in screened topsoil

  • Smoothing the topsoil for the final ground cover

  • Diverting water runoff away from buildings by creating positive slope and/or cutting swales for directing natural flow

Topsoil Stripping

Topsoil Stripping Excavation Contractor Bellingham WA

Topsoil on undisturbed building sites is mostly a liability. It must be stripped away from the actual construction footprint so the building or roadway is resting on hard, stable subsurface clay. A small portion of topsoil can be stored on-site and used for final grading while the remainder is usually hauled away.

With its high organic and moisture content, topsoil is a poor material for backfilling and must be kept separated from the clay fill material. In fact, we recommend stripping topsoil prior to surveying the building corners for best results. We’re happy to work with the surveyor’s schedule to include this time saving feature. Either way, Agate NorthWest has the experience and equipment to strip and handle topsoil according to your wishes.


  • No area is too large or too small to strip
  • Permitting, erosion control, surface runoff control, and ecology inspections
  • Complete stripping down to clay
  • Maintain different material separation
  • Haul surplus topsoil eliminating excessive material handling

Retention Walls

Retain Wall Construction in Bellingham by Agate Northwest
Retention walls provide level, usable area. They are the perfect solution to building up roadways, driveways, terracing sloped yards, holding sloped terrain away from buildings, or adding landscaping features for plantings. We ensure that our retaining walls have proper drainage behind the wall to eliminate water seepage and most importantly, to eliminate saturated soil from pushing against the wall.

Retention walls can be constructed in a variety of materials, but all have the same thing in common — to hold back and stabilize soil. We would be happy to discuss the many options for retaining walls and match the best option to your final goal. Agate NorthWest has the experience and know-how to build retaining walls that stand up to the test of time (and the force of gravity).

  • Poured walls
  • Allen blocks
  • Ecology blocks
