For any parking lot or loading zone, a site development plan and topographical map showing the location, design and specifications of entrances, exits, surfacing, landscaping, drainage, markings, lighting and grades of adjoining developed properties shall be subject to the approval of the Planning Board to ensure adequate protection to traffic safety and protection of adjacent areas. After completion, the Building Inspector, upon written notification from the Planning Board, shall thereafter issue a use or occupancy permit. Following the issuance of the use or occupancy permit, no changes shall be made in the site development plan or other topography of the property unless the same has been approved by the Planning Board.
