For any plan review site or for any zoning lot containing designated open space or an area of no land alteration, the City Planning Commission may authorize variations in the yard or court regulations as set forth in Section 107-46, inclusive, or in the location of parking, driveway or curb cut regulations as set forth in Sections 23-44 (Permitted Obstructions in Required Yards or Rear Yard Equivalents), 25-621 (Location of parking spaces in certain districts), 25-622 (Location of parking spaces in lower density growth management areas) and 25-632 (Driveway and curb cut regulations in lower density growth management areas) for the purpose of allowing proper arrangements of buildings, driveways or required parking areas so as to avoid the destruction of natural features.

As a condition for granting such authorizations, the Commission shall find that the proposed placement of buildings and arrangement of open spaces will not have adverse effects upon light, air and privacy on adjacent zoning lots and will preserve natural features in areas of no disturbance.
