Reducing Stormwater Runoff from Parking Lot with Permeable Pavement

Abstract

Increased urbanization has an impact on increased impervious surface, consequently the urban drainage system becomes gradually overloaded, with frequent spills and inundate urban areas. Upgrade or re-design the existing drainage system is not an effective solution because it does not address the source of the problem. It is necessary strategies for urbanization reduction of storm-water runoff. These strategies are aimed to reduce storm-water runoff mainly through water infiltration. One of the strategies is to develop permeable pavement. This study is aimed to test the capacity of permeable pavement through the development of full scale physical models in the parking lot. The results show that proposed permeable pavement are able to significantly reduce volume and peak discharge of storm-water runoff, delay the start of runoff and slow the peak discharge. The application of this proposed permeable pavement in the urban area is strongly recommended to reduce drainage load as well as to increase groundwater recharge.

Cost Analysis of Green Infrastructure Compared to Conventional Stormwater Storage

“…The project is designed to retain the 100year, 2-hour storm event, which is a total of 55 mm of rainfall as per the National Oceanic and Atmospheric Administration [25]. The weighted runoff coefficient is 0.84 [4]. It is estimated that the developed site would generate a volume of 6,401 m 3 of direct runoff, while the constructed runoff retention basins could retain 7,463 m 3 , which is for safety considerations.…”

“…All generated runoff is expected to drain into the retention basin and subsequently percolate to the subsurface to recharge the groundwater through a drywell system. The drywell system is designed to discharge the stored runoff completely within 36 hours after the runoff event has ended [4]. drain manholes, and five drywells to percolate the stored runoff into the underground retention basins.…”

“…Performing a VE study helps to determine cost savings from alternative designs. As an alternative and sustainable approach, LID is a proven method for reducing stormwater runoff and managing runoff quality [4]. In this paper, three land development projects were evaluated examining alternative LID's designed for each to study cost effectiveness.…”

“…In this paper, three land development projects were evaluated examining alternative LID's designed for each to study cost effectiveness. Two LID strategies including extensive green roof (GR) and permeable interlocking concrete pavements (PICP) were considered in the analysis [4,5,6]. Cost information on infrastructural capital investment and operation and maintenance (O&M) for a traditional drainage system were analyzed from a selection of historical projects.…”

Runoff Volume Reduction Using Green Infrastructure

“…Changes that are relatively easy to implement include surface of parking places along roadways (Figure 1), complete parking lots located near multi-family buildings (Figure 2) and garage driveways of single-family, semi-detached and terraced houses. Depending on traffic density and local conditions, the following are used: concrete grid pavers systems [11]-comprised of concrete blocks with voids inside the blocks which also create voids between blocks or plastic grids that add structural support to the topsoil and reduce compaction to maintain permeability (Figures 1 and 2). indicated as optimal [15].…”
