基于对不透水地表覆盖和水平衡研究的分析，认为传统的、单独下水道的第一代和替代的第二代可持续排水系统（SUDS）不能为城市集水区规划提供完全可持续的地表水管理方法。一个扩展的方法的基础上引入的微型和中型的植被SUDS系统到一个更广泛的绿色基础设施（GI）的框架，主张有效地解决现场和集水城市地表水问题。该方法基于街道绿化的综合规划实施，优化现有的生物过滤SUDS解决方案，以及绿色屋顶，落水管断开和子集水区河岸走廊，以实现最低2530%的树冠覆盖水平。一个叶出库存程序，利用地理信息系统和卫星图像，可以用来评估潜在的植被SUDS的位置和类型，以及它们可能对城市水循环和接收水健康的影响。然而，有必要确保将地理标志要素纳入城市排水基础设施的规划方法和协议。
Based on the analysis of impervious surface cover and water balance studies, it is argued that conventional, separately-sewered first-generation and alternative second-generation sustainable drainage systems (SUDS) cannot provide a fully sustainable surface water management approach for urban catchment planning. An extended approach based on the introduction of micro-and meso-vegetative SUDS systems into a wider green infrastructure (GI) framework is advocated to effectively address on-site and catchment urban surface water issues. The approach is based on the integrated planning implementation of street greening, with optimisation of existing biofiltration SUDS solutions, together with green roofs, downspout disconnection and sub-catchment riparian corridors to achieve a minimum 2530% canopy cover level. A leaf-out inventory procedure using GIS and satellite imagery can be employed to assess potential vegetative SUDS locations and types, and their likely impact upon the urban water cycle and receiving water health. However, there is a need to ensure that GI elements are incorporated into planning approaches and protocols for urban drainage infrastructure provision.
