Utilities and corridor expert witnesses
Transmission lines, pipelines and utility corridors take rights rather than title. What the easement document permits the holder to do decides most of the value, and it is read less often than the plan is.
Scope
The questions this expert answers
What percentage of fee value does this easement take
A judgement driven by the document, not by a customary figure.
What does it do beyond the corridor
A line across the middle of a development parcel can sterilise the land either side of it.
What is the utility asset itself worth
Where the taking acquires plant rather than land, specialised valuation applies.
Is the restriction permanent or for the works
A temporary construction easement is rent for the term plus restoration, which is a different calculation.
What does relocation cost
Wells, septic, irrigation and services that must be moved for the corridor to work.
Does the market price the perceived risk
On residential land near a pipeline or a transmission line it frequently does, and comparable sales show it.
Selection
What to check before engaging
| Criterion | What to look for |
|---|---|
| Discipline | Appraiser with corridor experience, or a utility valuation specialist |
| Document fluency | Reads the easement grant and values what it actually permits |
| Corridor record | Has worked transmission, pipeline or municipal corridor projects |
| Regulatory context | Understands the certification process behind the project |
| Engineering support | Works with an engineer on constructability and relocation cost |
| Independence | Not acting for the utility on this corridor |
In practice
Four ways easement valuations understate
Valuing only the strip, as though the restriction stops at the corridor boundary. Applying a conventional percentage of fee value without reading what this particular grant permits. Ignoring assignability, so an easement the holder may transfer or expand is priced as though fixed. And treating a temporary easement as permanent, or a permanent one as temporary.
The encumbrance rarely stops at the corridor. Where a route crosses a development parcel, the damage is the layout it makes impossible, and that belongs in the after value rather than in the strip.

In the meantime, how to find an expert sets out the four routes that reach the same population, and the questions worth asking before you engage anyone.
Questions about this category
They say I keep ownership, so why pay much
Because ownership without the right to use the land has limited value. A restrictive perpetual easement can take most of the value of the affected area.
Can I still farm the easement area
Often, depending on terms. The valuation should reflect whatever use genuinely remains, no more and no less.
Is a temporary construction easement worth arguing about
Yes, if the area is in use. It is rent for the period plus restoration, and on a commercial yard or a working farm that is not trivial.
