Effects of a porous pavement with reservoir structure on runoff water: water quality and fate of heavy metals
ABSTRACTThe present paper reports a study conducted to compare pollutant loading of runoff waters either collected at the outlet of a porous pavement with reservoir structure or coming from a nearby catchment drained by a conventional separate sewarage system, on the experimental site of Rezé (France). The mean pollutant loads measured at the reservoir structure appear notably lower than those ...

Cementitious porous pavement in stormwater quality control: pH and alkalinity elevation
A certain level of alkalinity acts as a buffer and maintains the pH value in a stable range in water bodies. With rapid urban development, more and more acidic pollutants flow to watersheds with runoff and drop alkalinity to a very low level and ultimately degrade the water environment. Cementitious porous pavement is an effective tool for stormwater acidic neutralization. When stormwater ...

Fire access case study summary 1
Environmental regulations that control and limit storm water runoff, reduce impervious surfaces, and increase green space have resulted in the growth of permeable pavements for traffic areas. The Geoblock® Porous Pavement System offers support for all vehicular loadings and protects the grass from the damaging effects of traffic while allowing natural groundwater replenishment. Examples where ...

Porous pavement application overview - Case Study
The permeable Geoweb® Solution As communities grow and experience increases in surface runoff from newly constructed buildings and hard parking surfaces, the capacity of existing stormwater runoff systems are often pushed beyond their limits. This problem has led to environmental regulations that require the use of stormwater retention and porous pavement systems. The Geoweb® system ...

Phipps Conservatory Event Parking - Pittsburgh, Pennsylvania - Case Study
GEOBLOCK grass porous pavement system accommodates 100 vehicles during peak events. In 2007, Phipps Conservatory and Botanical Gardens, the ‘Green Heart of Pittsburgh’ added a new green overflow parking area on its Schenley Park campus. With an added volume of visitors expected during the Chihuly at Phipps: Gardens & Glass event, the already busy facility deemed additional ...

Analysis on LID for highly urbanized areas’ waterlogging control: demonstrated on the example of Caohejing in Shanghai
Although a commonly applied measure across the United States and Europe for alleviating the negative impacts of urbanization on the hydrological cycle, low impact development (LID) has not been widely used in highly urbanized areas, especially in rapidly urbanizing cities in developing countries like China. In this paper, given five LID practices including Bio-Retention, Infiltration Trench, ...

Assessing the performances of low impact development alternatives by long-term simulation for a semi-arid area in Tianjin, northern China
For areas that are urbanized rapidly, the practice of low impact development (LID) has gained an important place in stormwater management and urban planning due to its capability and beneficial effects in restoring the original hydrological cycle. The performances of LID alternatives can vary substantially due to different climate conditions. This study investigated the performances of five LID ...

Cedar springs Presbyterian church parking improvements - Knoxville, Tennessee - Case Study
The Cedar Springs Presbyterian Church low-impact parking improvements project began as an addition to meet the Church’s parking needs and to provide a new site entrance to improve access and traffic circulation within the Church campus. The desire to develop the property as good stewards and include “green” or sustainable design practices led to the decision for this 169 -space, ...

Army Corps Chooses Porous Pavement System for Rock Island Project
Leaders at the Army Corps of Engineers prepared to construct a parking lot at their Rock Island Arsenal site in Rock Island, Illinois. After considering all of their options, they enlisted the help of the General Asphalt Construction Company and LPS Pavement to install an environmentally friendly pavement system that remains fully ready for active ...

Dual-function growth medium and structural soil for use as porous pavement
Permeable grass-covered surfaces can reduce the quantity of storm water runoff and filter out potentially harmful chemicals. The objective of this study was to develop permeable structural soils that sustained healthy turf growth and filtered heavy metals from contaminated pavement runoff. The basic soil medium was a 50:50 mixture (v/v) of expanded shale (ExSh) and quartz sand (QS). The ExSh ...

Simulation of heavy metal pollution from stormwater infiltration through a porous pavement with reservoir structure
ABSTRACTA laboratory experiment was set up to examine the ability of porous asphalt to retain metallic pollution. The results obtained confirm the retention of metals (Pb, Cu, Cd, Zn) by clogging particles, and a decrease in lead concentration can be observed in infiltrated runoff water. Moreover, the simulation of heavy metal transfer into the soil was carried out using the mathematical model ...

Great American Outdoors Act Provides Billions of Dollars for Overdue Repairs and Maintenance of U.S. National Parks
Congress recently passed the most significant piece of land conservation legislation in a generation. The Great American Outdoors Act (GAOA)—a rare bipartisan effort—will provide full funding for the Land and Water Conservation Fund at $900 million annually and will put $9.5 billion over the next five years toward the deferred maintenance backlog on public lands. The GAOA provides ...
