Most Appropriate Uses. Runoff percolates through voids in permeable
pavers and may be detained in the gravel bed, infiltrated into the underlying soil, or
both. By reducing the volume of runoff, permeable pavers help to decrease
pollution of sensitive waters. Permeable pavers can reduce or eliminate the
requirement for underground sewer pipes and conventional stormwater retention and
detention systems. Use of these materials can eliminate problems with standing water,
provide for groundwater recharge, control erosion of streambeds and riverbanks,
facilitate pollutant removal, and provide for a more aesthetically pleasing site. The
drainage of paved areas and traffic surfaces by means of permeable systems is an
important building block within an overall Low Impact Development scheme that seeks
to achieve a stormwater management system that mimics natural conditions.

Cost Data. Initial expenses for alternative paving materials may be greater
than conventional materials. However, the use of permeable pavers can often eliminate
the requirement for underground storm drainpipes and conventional stormwater
systems. Cost savings resulting from decreased investments in reservoirs, storm sewer
extensions, and the repair and maintenance of storm drain systems should be
considered. Interlocking concrete paving blocks cost to 8 per square meter
