Whenever the public necessity, convenience or general welfare indicates, the Board of Supervisors may, by ordinance, in accordance with applicable laws of the Pennsylvania Municipalities Planning Code, Act 247, as reenacted and amended, supplement or change the regulations, restrictions, boundaries or classifications of buildings, structures and land, as the same are established by this Chapter, or may hereafter be made a part thereof.
Applications or petitions for any change or amendments to existing zoning districts in the Township shall be made to the office of the Zoning Officer and shall be accompanied by a fee as determined by the Board of Supervisors payable to the Township Secretary and shall be deposited in the general fund. This fee is for the purpose of defraying costs of preparing the necessary plats, maps, data, legislation and notices and all official publications required by the Township and shall not be refundable even though the application is disapproved by the Board of Supervisors.
The Board of Supervisors may, from time to time, on its own motion or petition, after public notice and public hearing, amend the regulations and districts herein established, but no amendment as prepared by other than the Board of Supervisors shall become effective unless the same shall have first been submitted to the West Deer Township Planning Commission and Allegheny County for comments, and following the requirements of the MPC, Section 609:
A. 
MPC Section 609 requires a public hearing pursuant to public notice.
B. 
If an amendment involves a zoning map change, the public hearing notice must be posted by the Township on the property that is the subject of the map amendment at least one week prior to the date of the public hearing.
C. 
In addition, if there is a zoning map change that is not part of a comprehensive rezoning, notice of the public hearing must be mailed by the Township at least 30 days before the date of the hearing to the addresses to which real estate tax bills are sent for all real property located within the area being rezoned.
D. 
Any amendment not prepared by the local Planning Commission must be sent to the Planning Commission for review at least 30 days before the public hearing. This includes amendments prepared by the Board of Supervisors.
E. 
MPC Section 303(a)(3) and (b) requires that the Planning Commission recommendation be in writing and include a specific statement as to whether or not the proposed action is in accordance with the objectives of the formally adopted Comprehensive Plan. The recommendation is to be made within 45 days. Note that the Planning Commission makes recommendations and does not approve or disapprove a proposed amendment.
F. 
Zoning amendments must be sent to the Allegheny County Planning Agency for review at least 30 days prior to the public hearing and shall make a recommendation to the Board of Supervisors within 45 days and the proposed action shall not be taken until such recommendation is made or until the planning agency fails to act within 45 days. The county planning agency makes recommendations and does not approve or disapprove a proposed amendment.
G. 
Within 30 days after enactment, a copy of the amendment must be forwarded to the county planning agency.
A. 
A landowner who desires to challenge on substantive grounds the validity of a zoning ordinance or map or any provision thereof, which prohibits or restricts the use or development of land in which he has an interest may submit a curative amendment to the Township Board of Supervisors with a written request that his challenge and proposed amendment be heard and decided as provided in Section 916.1 of the Pennsylvania Municipalities Planning Code, Act 247, as reenacted and amended. The Township Board of Supervisors shall commence a hearing thereon within 60 days of the request as provided for in this Part. The curative amendment and challenge shall be referred to the Planning Commission or agencies as provided in Section 609 of the Pennsylvania Municipalities Planning Code, Act 247, as reenacted and amended, and notice of the hearing thereon shall be given as provided in Sections 610 and 916.1 of the Pennsylvania Municipalities Planning Code, Act 247, as reenacted and amended.
B. 
If West Deer Township does not accept a landowner's curative amendment brought in accordance with this section and a court subsequently rules that the challenge has merit, the court's decision shall not result in a declaration of invalidity for the entire Chapter and map, but only for those provisions which specifically relate to the landowner's curative amendment and challenge.
C. 
Where West Deer Township has determined that a validity challenge has merit, it may accept a landowner's curative amendment, with or without revision, or it may adopt an alternative amendment which will cure the challenged defects. The Township Board of Supervisors shall consider the curative amendments, plans and explanatory material submitted by the landowner and shall also consider:
(1) 
The impact of the proposal upon roads, sewer facilities, water supplies, schools and other public service facilities.
(2) 
If the proposal is for a residential use, the impact of the proposal upon regional housing needs and the effectiveness of the proposal in providing housing units of a type actually available to and affordable by classes of persons otherwise unlawfully excluded by the challenged provision of the Chapter or map.
(3) 
The suitability of the site for the intensity of use proposed by the site's soils, slopes, woodlands, wetlands, floodplains, aquifers, natural resources and other natural features.
(4) 
The impact of the proposed use on the site's soils, slopes, woodlands, wetlands, floodplains, aquifers, natural resources and other natural features, the degree to which these are protected or destroyed, the tolerance of the resources to development and any adverse environmental impacts.
(5) 
The impact of the proposal on the preservation of agriculture and other land uses which are essential to public health and welfare.
A. 
If West Deer Township determines that this Chapter or any portion thereof is substantially invalid, it shall take the following actions:
(1) 
West Deer Township shall declare by formal action, this Chapter or portions thereof substantively invalid and propose to prepare a curative amendment to overcome such invalidity. Within 30 days following such declaration and proposal, the Township Board of Supervisors shall:
(a) 
By resolution make specific findings setting forth the declared invalidity of this Chapter which may include:
[1] 
Reference to specific uses which are either not permitted or not permitted in sufficient quantity.
[2] 
Reference to a class of use or uses which require revision.
[3] 
Reference to the entire ordinance which requires revisions.
(2) 
Begin to prepare and consider a curative amendment to this Chapter to correct the declared invalidity.
B. 
Within 180 days from the date of the declaration and proposal, West Deer Township shall enact a curative amendment to validate, or reaffirm the validity of, this Chapter pursuant to the provisions required by Section 609 of the Pennsylvania Municipalities Planning Code, Act 247, as reenacted and amended, in order to cure the declared invalidity of this Chapter.
C. 
Upon the initiation of the procedures, as set forth in Subsection A, the Township Board of Supervisors shall not be required to entertain or consider any landowner's curative amendment filed under Section 609.1 of the Pennsylvania Municipalities Planning Code, Act 247, as reenacted and amended, nor shall the Zoning Hearing Board be required to give a report requested under Section 909.1 or 916.1 of the Pennsylvania Municipalities Planning Code, Act 247, as reenacted and amended, subsequent to the declaration and proposal based upon the grounds identical to or substantially similar to those specified in the resolution required by Subsection A(1)(a). Upon completion of the procedures as set forth in Subsections B and C, no rights to a cure pursuant to the provisions Sections 609.1 and 916.1 of the Pennsylvania Municipalities Planning Code, Act 247, as reenacted and amended, shall, from the date of the declaration and proposal, accrue to any landowner on the basis of the substantive invalidity of the unamended zoning ordinance for which there has been a curative amendment pursuant to this section.
D. 
West Deer Township, having utilized the procedures as set forth in clauses Subsections B and C, may not again utilize said procedure for a thirty-six-month period following the date of the enactment of a curative amendment, or reaffirmation of the validity of this Chapter, pursuant to Subsection B; provided, however, if after the date of the declaration and proposal there is a substantially new duty or obligation imposed upon West Deer Township by virtue of a change in statute or by virtue of a Pennsylvania Appellate Court decision, West Deer Township may utilize the provisions of this Section to prepare a curative amendment to its ordinance to fulfill said duty or obligation.
