Scientific studies have linked high levels of impervious surfaces to water quality degradation.
Two thirds of the impervious surfaces in developed communities are in the form of pavement related to automobile usage. Any design that uses alternatives to reduce impervious pavement is a positive step towards improving the quality of a community’s water resource.
Percoa Pre- cast and Pervious pavements are a recognized runoff reducing substitute for normal pavements in development or redevelopment of:
1.Driveways, including residential driveways, low-traffic roads, fire lanes and emergency access roads;
2.Parking areas; especially over-flow parking and those associated with office buildings, shopping centers and recreational facilities ; 3.Sidewalks;
4.Road shoulders and vehicle cross-overs on divided highways;
5.Boat launching ramps;
6.Others, including pool decks and patios.
The use of pervious pavement has been found to:
1.Reduce storm water runoff. (Even when pervious pavement structure is saturated, its rough surface texture continues to slow surface flow of stormwater);
3.Reduce flooding which may over-load combined sewer sewage treatment plants;
4.Require less land set aside and cost for development of retention basins;
5.Reduce pollutants in run-off;
6.Reduce irrigation of area plantings based on the seepage of rain into the sub soil surfaces;
7.Reduce thermal pollution (see also: temperature);
8.Lessen evaporative emissions from parked cars [ 85 KB];
9.Reduce glare and automobile hydroplane (skidding) accidents;
10.Reduce pavement ice buildup.
