Parking adjacent to buildings should be avoided to allow a buffer space for plantings and sidewalks. This space, or setback, is recommended to be a minimum of 20 feet between the parking area and adjacent buildings. In addition, provide a minimum of 20 feet for the buffer strip separating the parking area from the street. Force protection concerns may require a larger buffer strip. See UFC 4-010-01 (DOD Minimum Antiterrorism Standards for Buildings) for additional information concerning standoff distances to parking areas.
