Special Setbacks

Special setbacks are specified for the purpose of preserving extra ROW for future construction. Due to historical development patterns, many streets have public ROW widths that are less than needed to meet City safe and efficient circulation standards (Land Use Code, Chapter 9). Special setbacks identify where ROWs may eventually extend for new construction setback purposes.为预留额外道路红线（Right of Way，简称ROW）以供未来建设，特规定特殊退线要求。受历史发展格局影响，诸多街道的公共道路红线宽度未达到本市安全高效通行标准（《土地使用法规》第9章）。特殊退线条款明确了道路红线未来可拓展的范围，以满足新建项目的退线需求。
