Roadside Stormwater Master Plan Using Low Impact Development (LID)

Wang, J. L. / Che, W. / Zhang, W. / Li, J. Q. / Yi, H. X.

An innovative roadside stormwater master plan (located in the east part of core area in Ningbo east new city, China) on the basis of low impact development (LID) was proposed. The plan strategy employed a unique and unconventional approach for improving the health of local watersheds. LID techniques such as bioretention facilities, permeable paving, storm wetland, and ponds were utilized to reduce the runoff from roadways. Minimizing the stormwater flows from impervious surfaces and the potential pollutant load associated with the runoff will both improve the health of the watershed. Through full implementation of this plan, the developing area could realize reduction of runoff pollution loads (computed as COD), post-development general runoff coefficient was almost equal to the pre-development, significantly reducing stormwater runoff leaving the developing site. The plan included detailed descriptions of each stormwater management technology with a project summary, example photographs and a preliminary cost estimate on a single sheet for quick reference and comparison. LID techniques recommended by this plan are desire to advance to the forefront of sustainability and green infrastructure. This project provides an alternative to traditional methods of managing stormwater through the creative implementation of LID, and is a demonstration for other developing area and cities to follow.
