The background of Ord. 2008-06A, 8/18/2008, is incorporated at length below:
Lower Mount Bethel Township (hereinafter the "Township") recognizes the importance of preserving open space and conserving natural resources located within the boundaries of the Township, including farmland and forests.
Based upon information contained in the United States Department of Agriculture Natural Resource and Conservation Services Northampton County Soil Survey, most of the Township, 62%, consists of "prime agricultural land" as that term is defined in the Pennsylvania Municipalities Code, 53 P.S. § 10107.
The 2007 Township Comprehensive Plan reflects that roughly 71% of the land in the Township is enrolled in either the Act 319 or Act 515 preferential tax programs, and as of December 2003, (with that figure having increased after 2003), more than 23% of the land in the Township is part of agricultural security areas under the act of June 30, 1981, (P.L. 128, No. 43), 3 P.S. § 901 et seq., known as the Agricultural Area Security Law ("Act 43").
The farmland in the Township, particularly the prime agricultural land, is ideal for the growing of crops and raising of livestock, and the Board of Supervisors wishes to facilitate the continued availability of land for these purposes.
Encouraging the continuity, development and viability of agricultural operations by preserving and protecting agricultural land is a permitted and legitimate governmental goal pursuant to Pennsylvania law.
As of the time of enactment of this Part, in the entire Lehigh Valley Region consisting of Northampton County and Lehigh County, the Township has the highest percentage of farmland perpetually protected for future agricultural use by way of permanent easement.
A greater percentage of land in Lower Mount Bethel Township is devoted to agriculture than in adjacent townships and in Northampton County as a whole (74.3% of the Township as compared to 54.4% of Northampton County per Table 4-1 of the 2007 Township Comprehensive Plan).
The Board of Supervisors wishes to protect and promote the continuation of agriculture, particularly in areas with prime agricultural lands per the Governor’s Executive Order 2003-2 dated March 20, 2003, those areas being preserved farmland, farmland in agricultural security areas, farmland enrolled in Act 319 of 1974, as amended (Clean and Green Act), and land capability classes I, II, III, and IV and other soils of statewide importance as defined by the Natural Resources Conservation Service.
On January 19, 1968, the General Assembly of this Commonwealth of Pennsylvania, enacted Act No. 442, P.L. 992 of 1967, as amended by Act No. 153 of 1996, as amended by Act No. 4 of 2006, (hereinafter referred to collectively as the "Act"), for the purposes of acquiring and preserving open space property within the commonwealth.
Under the provisions of the Act, the Township Board of Supervisors may provide for exemption from further millage increases on certain categories of real property being used for open space and agricultural purposes by ordinance.
The Township desires to encourage the acquisition and preservation of open space and agricultural real property located within the boundaries of the Township by adoption of this Part providing exemption from further millage increases imposed on such property.
[Ord. 2008-06A, 8/18/2008, § III]
The exemption from further millage increase, herein sometimes referred to as a "millage freeze," authorized by this Part shall apply to all eligible real property in the Township, whether the real property meets the criteria of this Part prior to or subsequent to the effective date hereof. For prior acquisitions, the date on which the millage rate shall be frozen shall be the date that the last of the required ordinances or resolutions becomes effective. For subsequent acquisitions, the date on which the millage rate shall be frozen is the date the local governmental unit completes acquisition of the interest under this Part. Following the governing body of each taxing authority providing Township with prompt written notice of any real property that has been acquired and is eligible for the freeze or which becomes eligible for the freeze, the Township shall, in turn, give prompt notice to the appropriate tax collection agents of the exact amount of the millage, the date it was frozen, and each parcel to which the freeze applies. Failure of the Township to receive notice of real property eligible for the freeze as required by law shall result in loss of the exemption for the subsequent tax year. The exemptions granted under this Part shall not be considered by the State Tax Equalization Board in deriving the market value of school district real property so as to reduce the subsidy to the school district or to increase the subsidy to any other school district.
[Ord. 2008-06A, 8/18/2008, § IV]
Any real property otherwise eligible for exemption hereunder, may be released from exemption upon written request of the owner delivered to the Township and the other governing bodies of each taxing district authorizing exemption on or before the real estate tax levy in any tax year.
[Ord. 2008-06A, 8/18/2008, § V]
If a landowner changes the use of any tract of land subject to the millage freeze under this Part to one which is inconsistent with the provisions of the Agriculture Area Security Law, or for any other reason the land is removed from a land use category under § 24-502 of this Part, except for a condemnation of the land, the land so removed and the entire tract of which it was a part shall be subject to roll-back taxes plus interest at the rate of 6% per annum. Rollback taxes shall be calculated based on an amount equal to the difference between the taxes paid or payable in the previous 10 tax years or since the tax year of the date of acquisition, whichever is less, had the millage not been frozen. The unpaid taxes required to be repaid under the section shall act as a lien upon the property, collectible in the manner provided by law for the collection of delinquent taxes.
[Ord. 2008-06A, 8/18/2008, § VI]
The Township may repeal this Part at any time; provided, however, that any real property which is subject to the exemption when the Part is repealed shall thereafter continue to be exempt from millage increases, but only for so long as such real property otherwise continues to be eligible for exemption under the Act.
