In September, the Pacific Northwest Research Station released its report “Calculating the Green in Green: What’s an Urban Tree Worth?”. Research was completed in Sacramento, CA and Portland, OR.
Geoffrey Donovan, research forester with the PNW Research Station, determined that trees planted on the south and west sides of Sacramento houses reduced summertime electricity bills by an average of $25.16. In a second study in Portland, Donovan’s team found that street trees growing in front of or near a house added an average $8,870 to its sale price and reduced its time on the market by nearly 2 days. These economic benefits spilled over to neighboring properties: a neighborhood tree growing along the public right-of-way added an average of $12,828 to the combined value of all the houses within 100 feet.
