Where residential subdivisions are to be developed adjacent to developed commercial or industrial sites, or arterials, buffer strips or other protective treatment (e.g., deeper lots) shall be required as may be practicable. A strip of land five feet wide and parallel to the residential use shall be planted with a vegetative screen of hardy evergreen shrubs or trees. The screen shall be no less than four feet in height at the time of planting and shall be maintained in a healthy condition by the subdivider. (Ord. 484, 2006)
