Landscaping. Those portions of all front, side, and rear yards that are not used for structures, off-street parking, access drives, gardens, or recreational amenities shall be attractively planted and maintained with native hardy trees, shrubs, and grass lawns or other ground covers as set forth on a planting plan to be furnished by the developer with the site plan application. Special landscape treatments and/or fences may be required by the Planning Board along side and front property lines so that the parking area is appropriately buffered from adjacent residential properties. Every effort shall be made to disturb a minimal amount of property.
