The applicant shall propose, and the Town Board shall review and approve a construction schedule for the development of an approved PRDS. Generally, commencement of development of the PRDS, or the first phase if a phased PRDS is approved, must occur within two years of the date that the final site plan of the PRDS is approved. However, it is recognized that, depending on the scale and complexity of the development, and overall market conditions, consideration may be made with respect to the reasonable time necessary for the applicant to obtain construction financing, insurance and bonds, executing construction contracts, and other such aspects involved in a development project. Thus, the Town Board may extend the time period allowed for commencement of construction depending on the circumstances.
