If the Village Board approves the establishment of a PRD Planned Residential Development District, the Zoning Map shall so be amended. When rezoning land for such use, the Village Board shall establish the maximum number and type of dwelling units therein and may, if it feels it necessary in order to protect the public health, safety and welfare of the community, attach to its zoning resolutions any additional requirements for the applicant to meet. Such requirements may include, but not be limited to, visual and acoustical screening, land use mixes, order of construction and/or occupancy, vehicular and pedestrian circulation systems, availability of sites within the area for needed public services, parks and open spaces and the protection of natural and/or historic sites. Any application for the establishment of a PRD Planned Residential Development District shall be subject to site development plan review as provided in Article III of this chapter. The Planning Board shall approve the final site development plan prior to effectuation of the Zoning Map amendment and the issuance of a building permit by the Code Enforcement Officer. Such site development plan may constitute the entire development or, if staged, only a portion thereof. If the project is to be constructed in stages, only that portion receiving site development plan approval may be effectuated.
