Pennsylvania Statutes Title 53 P.S. Municipal and Quasi-Municipal Corporations § 10709. The findings

(a) The governing body, or the planning agency, within 60 days following the conclusion of the public hearing provided for in this article or within 180 days after the date of filing of the application, whichever occurs first, shall, by official written communication, to the landowner, either:

Failure to so act within said period shall be deemed to be a grant of tentative approval of the development plan as submitted.  In the event, however, that tentative approval is granted subject to conditions, the landowner may, within 30 days after receiving a copy of the official written communication of the governing body notify such governing body of his refusal to accept all said conditions, in which case, the governing body shall be deemed to have denied tentative approval of the development plan.  In the event the landowner does not, within said period, notify the governing body of his refusal to accept all said conditions, tentative approval of the development plan, with all said conditions, shall stand as granted.

(b) The grant or denial of tentative approval by official written communication shall include not only conclusions but also findings of fact related to the specific proposal and shall set forth the reasons for the grant, with or without conditions, or for the denial, and said communication shall set forth with particularity in what respects the development plan would or would not be in the public interest, including, but not limited to, findings of fact and conclusions on the following:

(c) In the event a development plan is granted tentative approval, with or without conditions, the governing body may set forth in the official written communication the time within which an application for final approval of the development plan shall be filed or, in the case of a development plan which provides for development over a period of years, the periods of time within which applications for final approval of each part thereof shall be filed.  Except upon the consent of the landowner, the time so established between grant of tentative approval and an application for final approval shall not be less than three months and, in the case of developments over a period of years, the time between applications for final approval of each part of a plan shall be not less than 12 months.
