Alleys constructed from permeable pavers get new signs
Boise – The signs give those who live and work near Downtown alleys outfitted with experimental permeable paver tips on how to protect the pavers, and also explain how the cutting-edge paving treatment works. Two Downtown Boise alleys were equipped with permeable pavers last summer between 3rd Street and 4th Street, and between 13th Street and 14th Street, north of Main. A third alley, located between 5th and 6th streets, just north of Idaho Street, was recently completed.
Permeable pavers are part of the Highway District’s green infrastructure initiative to better handle environmental issues such as storm water runoff. Permeable pavers are designed to help infiltrate rain and melted snow and allow it to seep back into the ground. Rocks and dirt help to scrub pollutants out of the water, and the runoff naturally returns to the ground water supply and ultimately to the Boise River.
However, pavers should not have debris swept or blown on to them and nothing should be placed on top of them for storage purposes. Water, salt or deicers should also not be discharged on to the pavers. Cigarette butts should be discarded in a separate receptacle. The signs serve as a reminder of these important tips to users of the alleyways.
The permeable pavers are a pilot project, and the Highway District will be watching these three alleys closely over the coming years to see how the pavers handle drainage and maintenance issues. If they are successful, Ada County residents can expect to see more structures made using the environmentally-conscious pavers in the future.
