Property use requirements:

Property must be subject to a conservation easement agreement between the owner or owners and the town government, under which the owner or owners grant interests or rights in real property to the town government for the preservation of open space or open areas. "Open space" or "open areas" means any space or area characterized by material scenic beauty or whose existing openness, natural condition or present state of use, if retained, would enhance the present or potential value of abutting or surrounding urban development or would maintain or enhance the conservation of natural or scenic development. For the purposes of this definition, "natural resources" includes, but is not limited to agricultural lands defined as open lands actually used in bona fide agricultural production.

If there is a violation of the terms and conditions of the conservation easement agreement or if such conservation easement agreement is canceled by the town board upon petition, then the owner or owners of such property must pay to the town government all taxes abated under the conservation easement agreement, including, if applicable those taxes imposed by the county, school districts and all special improvement districts and other taxing districts to which the property is subject. Repayment of the aforementioned taxes is equal to five times the taxes saved in the prior year in which the land benefited from a conservation easement exemption, plus interest of six percent per year compounded annually for each year in which an exemption was granted, not to exceed five years.

Certification by state or local government:

A property receiving this exemption must first be subject to a conservation easement agreement between the owner or owners and the town board.

Required construction start date or other time requirement:

None.

Local option

Yes. Each eligible town may choose whether or not to allow the exemption. The option to exempt must be exercised through a local law (after a public hearing). Upon the town's adoption of such a local law, the county in which the town is located may enact a local law allowing the exemption. Likewise, the school district or districts in which the eligible property is located may each pass a resolution allowing the exemption.
