Low Impact Development (LID) technology is a relatively new stormwater management strategy developed to reduce or eliminate the need for traditional stormwater infrastructure. One popular LID is porous pavement because it can treat stormwater both in terms of water quantity and quality on site. Porous pavement is a pavement with a high permeability and thus, can collect, store and treat stormwater runoff. The system allows stormwater to flow from the surface to a sub-structure (the region spanning from the bottom of surface pavement layer to the top of the subgrade and includes the bedding layer and reservoir course and a geotextile). The water finally reaches a subdrain or is allowed to further infiltrate into the surrounding soil to recharge groundwater if there is no impervious liner. Stormwater is temporarily stored in sub-structure of the permeable

低影响开发（LID）技术是一种相对较新的雨水管理策略，旨在减少或消除对传统雨水基础设施的需求。一种流行的 LID 是多孔路面，因为它可以在现场处理雨水的水量和水质。多孔路面是一种具有高渗透性的路面，可以收集、储存和处理雨水径流。该系统允许雨水从地表流至下部结构（从地表路面层底部到路基顶部的区域，包括垫床层、水库层和土工织物）。如果没有不透水衬里，水最终到达地下排水沟或进一步渗入周围土壤以补给地下水。雨水暂时储存在透水结构的下部结构中
