Whether Parkinson's conservation easement was valid and enforceable so that the assessors had to account for its development restrictions in valuing the property.
Holding
No. The easement was invalid because it did not identify with reasonable certainty the land subject to its restrictions and the land excepted for residential use.
Reasoning
A valid easement instrument must identify the easement and the dominant and servient estates with reasonable certainty. The description must be precise enough that a surveyor can locate the affected land; if the servient land cannot be identified, the conveyance is ineffective. The court held that this ordinary certainty requirement, rather than any categorical statutory bar on restrictions involving a dwelling, controlled the case.
The easement exempted the use of one single-family residence and its usual outbuildings, but it did not specify how much land surrounding the existing house was also exempt. Parkinson's appraiser assumed that the residence required about seven acres, yet the record supplied no basis for that figure. The necessary area could reasonably vary greatly depending on the owner's view of what was needed for residential use. As a result, the size of the restricted estate depended on an arbitrary estimate rather than on the recorded instrument.
The uncertainty also extended to location. The easement allowed one single-family residence anywhere on the property. If the existing home were destroyed, a replacement could be built at another location, creating a roving and unlocated exception to the development restrictions. Thus, the instrument failed to establish both the boundaries and the location of the land subject to the conservation restriction.
The statutory framework supported that conclusion. Although the Legislature contemplated that a grantor of a conservation easement might remain in residence, the grantor had to identify a parcel distinct from the house that would be subject to the restriction. General Laws c. 59, § 11 requires land subject to a conservation easement to be assessed as a separate parcel, and G. L. c. 184, § 33 requires sufficient identification of restricted land for the public restriction index. Because this easement did not identify a separate restricted parcel clearly enough for assessment, the assessors properly declined to discount the property's value.
