its path. We call this <STRONG>runoff</STRONG>. Runoff not only contributes to 
flooding and erosion; it also plays a part in the contamination of our water 
supply.</blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://science.howstuffworks.com/green-pavement.htm">Runoff occurs because traditional pavement is <STRONG>nonporous</STRONG> -- 
meaning it doesn't allow rainwater to settle back into the ground. <STRONG>Green 
pavement</STRONG>, a relatively new concept in green building, is a permeable 
and porous pavement (try saying that three times fast) that absorbs rainwater 
instead of repelling it. It allows water to return to the ground, which means 
the water doesn't wash into the sewer, along with oil, gas and pesticide 
residue. </blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://science.howstuffworks.com/green-pavement.htm">Green pavement is a viable alternative for footpaths, driveways and parking 
lots, and one day it could revolutionize highway systems.</blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/FD04A882-01E9-4B7F-B8E8-7B33D53B2F49/blog/" title="blog or email this clip"><img src="http://content6.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
