Boundary & ALTA Surveys

Residential, commercial and large-acreage boundary surveys are the core of our business. Our historical records help us work quickly.

What it covers

  • Residential, commercial and large-acreage boundaries
  • Recovery of original 1800s government corners
  • Records of survey and corner records
  • ALTA/NSPS surveys on 1,000 to 5,000+ acres
  • Intermediate points on property lines for new fencing
  • Parcel maps and lot line adjustments
  • Expert witness work

Our records hold more than 14,800 surveys, so we research a parcel quickly.

You may hire a land surveyor only once in your life. So we take time to learn what you need. Then we help you choose the right approach and product.

We also deliver ALTA/NSPS surveys on 1,000 to 5,000+ acres.

A three-step process

  1. Step 1: Research and calculations

    • If a parcel map or a subdivision map created your parcel, this step is short.
    • If a deed or a government patent created your parcel, this step can take more time.
  2. Step 2: Field survey

    • Find, flag and verify the existing property corners.
    • Re-set corners that someone destroyed.
    • Set property corners that no recorded map shows.
    • Set intermediate points on the property line to help with fencing.
  3. Step 3: Mapping

    • Map of survey: a simple map that we do not record.
    • Corner record: a map and a document that we file with the County Surveyor.
    • Record of survey: an 18″ by 26″ map that we record with the County.

A corner record is required when you re-set corners that a record map shows.

A record of survey is required when you set corners that no previous record map shows.

Land use questions

A survey often starts with a land use question. Can I divide my parcel? Can I give 10 acres to my son? Zoning is often not the whole story. We meet with you and help you get the most out of your property.

We also help you process your application with the correct agencies. Land planning services include:

  • Parcel maps
  • Subdivision maps
  • Lot line adjustments
  • Site plans

Expert witness work

We work as expert witnesses on complicated boundary cases. The history, the evidence and the math all have to hold up.

For the history, we use original government field notes, old deeds and decades of local survey records.

For the evidence, we dig for stones, pipes and bearing trees that crews set more than a century ago.

For the math, we use least-squares adjustments, proportioning and closures that we can defend.
