Terms

Perpetual easement that stays with the land through ownership changes; building envelopes and agricultural/scenic/natural areas designated in the easement; ongoing stewardship by Ag + Open Space staff. Funded by county sales tax plus state/federal funds (e.g., NRCS RCPP).

Published amounts: The appraiser values the land before placement of the conservation easement and after placement of the conservation easement. The difference in those two values is the maximum value of the conservation easement itself, and once we have that value we work with the landowner to negotiate the actual purchase price.
