Sustainable Sites Initiative has a collection of case studies that illustrate green building practices. The most interesting to us is Garden/Garden:A Comparison in Santa Monica, where the city installed a traditional front yard lawn garden and a low-water, native, sustainable design garden on adjacent lots so that people could see the side by side comparison.
The native garden cost about one third more to install, $16,700 vs. $12,400; that cost difference came from the installation of a DG walkway to replace the existing concrete walkway and installation of rain gutters and a stormwater infiltration pit.
The native garden used 77% less water, 283,981 gallons/year vs. 64,396 gallons/year.
The native garden generated 66% less green waste, 219 pounds/year vs. 647.5 pounds/year.
The house and yard of the traditional garden look like relics from the sixties. I salute the owners for taking a hit for science.
