You would want to hire an your own appraiser to tell you if the amount is in fact fair market value. There are many factors that an appraiser takes into account to make their determination. Did you receive a copy of the appraisal by the "independent appraiser"? I would want to check the comparables.
The methodology for easement valuation is based upon the bundle of rights: the
fair market value of an easement is its contribution to the bundle comprising the
ownership rights of a specific property.
An easement is an interest less than the fee estate, with the landowner retaining
full ominion over his realty subject only to the easement, and the landowner may
make any use of his realty that does not interfere with the easement holder’s
reasonable use of the easement.”

Before and After Method
The Before and After method is used to determine whether, and the degree to
which,an easement changes a property’s use and value. Under the Before and
After method, the value of the property after the imposition of the easement is
subtracted from the value of the property before the imposition of the easement to
estimate the value of the easement. Each value conclusion is made as of the same

Appraisal Methodology (Cont’d)
If there is a substantial record of sales of easements comparable to the
donated easement (such as purchases pursuant to a governmental program),
the fair market value of the donated easement is based upon the prices of
such comparable easements.
Given the lack of comparable sales of easement
encumbered properties, the appraiser must visualize and consider the effects the easement restrictions will have on the property relative to other properties,....”http://www.norcal-ai.org/amass/doc-get-pub/article/351/Valuation_of_Subsurface_Easements_S._Tish.pdf
I would want to see the comparables on the appraisal that came up with the $1000valuation.
The formula used is set put below:
Gather details of the easement. If it is already granted, obtain a copy of the easement deed. The value of the easement depends on its location, purpose and use. Put simply, appraisers do not value the easement itself, but its effect on the burdened property. For example, a small gutter overhang between two residential houses is unlikely to have any impact on the use of the burdened house, so has minimal value. A large right of way that prevents an owner from developing his tract of land is another matter.
Ascertain the market value of the whole of the burdened land, as if the easement does not exist. This is not just the land over which the easement is exercised, like the width of a right of way, but the larger plot owned by the burdened landowner. Express the market value as an appropriate per unit value (per square foot, per acre). This is your "before scenario."
Consider the remainder. This is the burdened landowner's larger tract of land, less the easement area. Value the remainder on the basis that it is subject to the easement. Use comparison or paired sales analysis to assess the value of other plots in the locality, sold with and without the burden of a similar easement, to ascertain the impact of the easement. Adjust for special circumstances; for example, the easement will have a lesser value on the remainder if it is limited in time. Express the value according to your price per unit. This is your "after scenario."
Measure the easement land. Include the whole length and width. Do this by reference to plans and a ground inspection.
Deduct the "after scenario" value from the "before scenario" value to arrive at a value per unit of the easement land. Multiply by the measured area of the easement land to arrive at a total market value."

You can always counter for a higher amount.
