Where, after the effective date of this act, a curative amendment proposal is approved by the grant of a curative amendment application by the Borough Council pursuant to §
250-41A(2)(b) or
a validity challenge is sustained by the Zoning Hearing Board pursuant to § 250-41(A)(1)(a) or the court acts finally on appeal from denial of a curative amendment proposal or a validity challenge, and the proposal or challenge so approved requires a further application for subdivision or land development, the developer shall have two years from the date of such approval to file an application for preliminary or tentative approval pursuant to Chapter
215, Subdivision and Land Development, or any planned residential development provisions of a Borough ordinance. Within the two-year period, no subsequent change or amendment in the zoning, subdivision or other governing ordinance or plan shall be applied in any manner which adversely affects the rights of the applicant as granted in the curative amendment or the sustained validity challenge. Upon the filing of the preliminary or tentative plan, the provisions of the applicable Chapter
215, Subdivision and Land Development, section shall apply. Where the proposal appended to the curative amendment application or the validity challenge is approved but does not require further application under any subdivision or land development ordinance, the developer shall have one year within which to file for a building permit. Within the one-year period, no subsequent change or amendment in the zoning, subdivision or other governing ordinance or plan shall be applied in any manner which adversely affects the rights of the applicant as granted in the curative amendment or the sustained validity challenge. During these protected periods, the court shall retain or assume jurisdiction for the purpose of awarding such supplemental relief as may be necessary.
