Nick Irvine, a water harvesting installer in Phoenix and WMG Certification graduate, posted a blog entry about a recent WMG workshop he participated in. The following is an excerpt; for the full article with photos, click here.
"As I pull onto the street, I already see the digging sites. They have excavated some of the area in preparation for our class. I also see a few giant mountains of materials. Some gravel, some rip-rap (large boulders and rocks) and a pile of shredded tree parts (mulch). We begin with a circle around some bagels and a discussion of the reason for this project.
The Issues: Pollution running downstream from car oil, trash, feces and other chemicals. Also, there is the air pollution from passing cars, noise pollution from students arriving and leaving the UA games, and the intense heat due to almost no shade along the sidewalk.
The Solution: A healthy array of native trees and plants along the streets. The basins Job, hold the plantings will gather street runoff (including all of the bad stuff it contains!). The plants job, in a way, to dilute the pollution downstream. They will trap and breakdown the toxins and oils slowly...added bonus---> it also catches litter where neighbors are more likely to pick it up. The alternative is that the trash makes it into washes, where not many people will go to pick it up! Cool bonus huh? well, not nessesarily for the neighbors I guess."
