Care, Professionalism & Impartiality
This is a substantial body of work and must be completed with care and professionalism under the rules regulating the profession and the legal guidelines governing boundary surveying.
When a landowner requests our services, we consider it an honor. We apply all our skill and resources to provide thoughtful consultation and a quality work product. We work hard to navigate difficult boundary matters with our clients and their neighbors, seeking a resolution that addresses the concerns of all parties. We are not “hired guns” for our clients; we hold to the ethical responsibility of remaining impartial for the benefit of all landowners.
When boundary conflicts cannot be resolved between neighbors, we work with our clients’ legal counsel to resolve the issues, including serving as expert witnesses in litigation when needed. We always work hard to keep our clients from reaching this last resort.
Don’s additional credential as a Licensed Forester (L.F.) is especially useful when retracing deeds that refer to historical natural evidence—an “old spruce tree,” a woodlot line, or another monument whose meaning depends on familiarity with forests and changing landscapes.
Historical Survey Archive
Donald R. Richards, P.L.S., L.F.
Richards, Cranston & Chapman, LLC
The archive preserves surveying records dating to the 1700s, including original field notes from the 1790s Northport survey conducted for General Henry Knox. The collection reflects the region’s historical ties to Knox’s extensive land holdings.
Using these records, the practice researched and drafted the original lotting map for Lincolnville, connecting early field evidence, deeds, and historical land divisions in a single working record.
The archive preserves work by these former surveyors and firms:
- O. H. Tripp
- H. P. Farrow
- Edwin Rose
- A. D. Blackinton
- David Knowlton
- Franklin Wood
- Edward W. Coffin
- Cothern & Cranston
- Cothern & Chapman
- Harold Brown
Additional plans and records by other surveyors are cataloged as the archive continues to grow.
Aerial Photos & Drone Services
Don has been designated by the court as an expert in aerial-photo evidence. Historical aerial photographs from the 1930s and 1940s can reveal former roads, shorelines, occupation, land use, and other evidence important to boundary analysis.
Drone flights provide both oblique and vertical photography, often capturing hundreds of photographs in a single flight. Specialized software stitches the images into mosaics or orthophotos. Orthophotos are corrected for lens distortion, camera tilt, parallax, and topography so they can support accurate measurement and mapping.

Experience in Forensics
Forensic boundary work begins with collecting data, establishing facts, and giving courts clear, impartial information for boundary determinations. The analysis is guided by principles of law and the rules of retracement established by the courts.
Don’s expert-witness experience includes preparing affidavits and reports, participating in depositions, giving testimony, and creating illustrations that make complicated evidence understandable in court.
The primary goal is still to keep clients out of court. Thorough research, careful documentation, and early identification of the controlling evidence often make resolution possible before litigation becomes necessary.
