Whenever the particular circumstances of a proposed development require compliance with either another procedure in this chapter, the requirements of Chapter 105, Subdivision of Land, or the requirements of the State Environmental Quality Review Act, the Planning Board may integrate, if it deems appropriate and to the extent of its authority under law, site plan review as required by this section with the procedural and/or submission requirements for such other compliance. Such integration of procedures may require, upon mutual written consent of the Planning Board and the applicant, reasonable modification of the time schedules otherwise stated in this section or in said related regulations or requirements.
