“…The reduction in percentage runoff was somewhat disappointing at only 22%. For a different car park, Schluter and Jefferies (2002) found that discharged metal concentrations were restricted by the use of porous concrete block surfaces (e.g. Cd < 0.01 µg l -1 ; Zn < 22.2 µg l -1 ) and for 16 storms the average outflow discharge volume was 46.5% of the incident rainfall.…”

Traffic emissions contribute significantly to the build-up of diffuse pollution loads on urban surfaces with their subsequent mobilisation and direct discharge posing problems for receiving water quality. This review focuses on the impact and mitigation of solids, metals, nutrients and organic pollutants in the runoff deriving from car parks. Variabilities in the discharged pollutant levels and in the potentials for pollutant mitigation complicate an impact assessment of car park runoff. The different available stormwater best management practices and proprietary devices are reported to be capable of reductions of between 20% and almost 100% for both suspended solids and a range of metals. This review contributes to prioritising the treatment options which can achieve the appropriate pollutant reductions whilst conforming to the site requirements of a typical car park. By applying different treatment scenarios to the runoff from a hypothetical car park, it is shown that optimal performance, in terms of ecological benefits for the receiving water, can be achieved using a treatment train incorporating permeable paving and bioretention systems. The review identifies existing research gaps and emphasises the pertinent management practices as well as design issues which are relevant to the mitigation of car park pollution.

“…Permeable pavements offer one solution to convert parking areas as well as low-density traffic lanes and pedestrian pathways into pervious surfaces towards a more sustainable approach in road construction practices (Schlüter and Jefferies 2002). Permeable pavements include both monolithic (i.e.…”

A small size laboratory test-bed has been realized at the University of Genoa in order to evaluate the drainage capacity of permeable pavements by monitoring inflow, runoff and subsurface outflow. The laboratory test programme has been designed in order to investigate the influence of the rainfall intensity and pavement slope on the hydrologic response of permeable pavements. Four permeable pavement systems realized combining two paver typologies (concrete cell and pervious brick) with two filter layers made of recycled glass aggregate and a mix of gravel and coarse sand are tested. The hydrologic response of permeable pavements is analysed by using a dimensionless volume index (discharge coefficient) and a timing index. Laboratory results reveal that the hydrologic performance is fairly consistent for all the investigated permeable pavements. The recycled glass aggregate turns out to be a valid solution. No surface runoff occurs even at 98 mm/h rainfall intensity
