Gowanus Canal
I recently met with Andrew Faust, permaculture expert and founder of the
Center for Bioregional Living
for an informal chat about developing garden designs in New York City. Initially we met to discuss the use of plants to clean leads and other metals from the soil. Our conversation veered into discussions on drain water management, composting, planting to keep mosquitoes at bay, and even the art of fruit tree pruning. Andrew is a wealth of knowledge on practical ecological practices and sustainable living so I held an impromptu interview for City Dirt. He's going to be conducting a workshop on Permaculture Design here in New York City that will be held over the course of 11 Fridays and 2 Saturdays from 9am-4pm.

This spring Prospect and
Refuge will be working with Andrew to create city specific designs for using rainwater run-off, helping home owners set up their composting systems, and combining dwarf fruit trees and other edibles with native and perennial plants for beautiful, tasty, bird and butterfly friendly gardens.
City Dirt: What is one of the most important sustainable issues for dense urban areas?
Andrew: Rain water run-off control is probably one of the simplest ways to keep raw sewage from draining into the waterways and city infrastructure. You can create wetlands in the back or side yard of your brownstone, and put that water to good use.
City Dirt: Like a cistern system that traps rainwater?
Andrew: Cisterns are good except for when there's a high flow rain event. Then you want a system to channel and harvest it.
City Dirt: But if you have it draining right into your yard, won't you have a bog that attracts mosquitoes?
Andrew: Absolutely not. You just use plants that have a high water uptake. Bullrushes, wild iris, red maple, red osier dogwood, elderberry and blueberries will all use the run off. Mussolini was known to dry swamps with plantings of elms and eucalyptus. These plants can literally suck up thousands of gallons of water a day. By doing this, you keep sewage from running into places like the Gowanus. It's estimated that 160 million gallons of raw sewage goes directly into the canal a year from rainfall.
City Dirt: Is there any hope for the lavender lake, aka Gowanus?
Andrew: I want to design floating pond remediators. These are rafts will host plants that clean the toxins out of the water. In China they created floating walkways to clean up the open sewage canals. Not only are the plants removing the toxins from the water, but you have a beautiful area for people to stroll through and enjoy the waterways.
City Dirt: If it could work for the Gowanus, then it could work for Newton Creek, right?
Andrew: I don't see why not. What exactly is Newton Creek? Is that a natural waterway or a canal?
City Dirt: I'm not sure, but it dead-ends into industrial wasteland and people are pretty scared of it. So what else can city dwellers do that's relatively simple?
Andrew: Compost. It has been figured that 30% of our waste is actually table scraps. So if you have either access to a community garden or your own backyard, then it's simple to cut your waste being trucked to landfills by a third. And I'm seeing biodegradable cups at places like coffee shops. These you can toss in with your garden clippings and table scraps.
City Dirt: What about rats getting into the outdoor recycling bins. They're kind of our staple wildlife here. And they're savvy.
Andrew: Make them rat proof. Really, really rat proof.
