Any activity requiring site plan, special use permit, or subdivision plan approval that is proposed within 100 feet of a stream or its banks shall be reviewed and approved by the Planning Board. No alteration, whether by excavation, filling, grading, clearing, draining or similar disturbance, shall be made that will negatively impact a stream. The Planning Board, in its discretion, and based on a consideration of the extent and type of disturbance to the stream and/or the adjoining one-hundred-foot regulated area, may require submission of analyses to determine how said disturbances affect the water level and flow, recharge, drainage patterns, water quality, and aquatic ecosystems associated with said stream. The Planning Board shall ensure that any activity is conducted in a manner that minimizes potential environmental impacts to the stream. Where the applicant must obtain a stream disturbance or discharge permit from the NYSDEC, Planning Board approval shall be conditioned on the agency's approval.
