Parking adjacent to buildings should be avoided to allow a buffer space for plantings and sidewalks. This space, or setback, should 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. Force protection concerns often require a larger distance separating the parking area from an inhabited building. See UFC 4-010-01 for more information on standoff distances.
