Dear Andrejs and Friends--For lots of info check out http://www.stormh2o.com/may-june-2003/pavement-porous-bmps.aspx Note that this site says that the porous asphalt doesn't work well with slopes above 6 percent. Pervious concrete may also be an option: http://www.pervious.com/ The following deals with many design and construction considerations: http://www.deq.state.mi.us/documents/deq-swq-nps-pap.pdf For a local example of the use of porous asphalt see http://www.hort.cornell.edu/UHI/outreach/pdfs/cu_porous_asphalt.pdf It might be possilbe to contact some of the authors of this document at Cornell and get specific additional advice and info on local contractors who provide porous asphalt and pervious concrete. Other options an studies are offered at http://www.partnersforcleanwater.org/images/Boise%20Porous%20Pvmt%201%20Bruce%20Ferguson.pdf Here is yet another option, a porous surface made of plastic, from Europe: http://www.greeninnovations.ca/greeninnovations.php?to=garden-grid&dm=gl I hope some of this is useful information. I would be very interested in hearing the results of your driveway project. Thanks. Tom ****************************************** Tom Shelley 118 E.
