Chicago River Blue/Green Corridor Economic Study Shows Big Benefits
Incorporating environmentally sensitive design by developing the Chicago River system as a blue/green corridor would provide an additional economic return on investment of $1.77 for every $1 spent according to a new report issued by the University of Wisconsin-Whitewater’s Fiscal and Economic Research Center.
Entitled The Blue/Green Corridor: Establishing the Intersection Between Economic Growth and Environmental Design, the study found that a people, wildlife, and environment-friendly approach to riverfront development would create an additional $192 million in total economic benefits annually over a 15-year timespan. According to the report commissioned by µÚÒ»³Ô¹Ï and released March 14, 2019, a blue/green corridor also would support 1,614 jobs annually as well as improve water quality, biodiversity, recreational opportunities, and public health. Similarly such an approach would help mitigate flooding, air and water pollution, and the urban heat island effect.
“In the face of climate change and pressure from urban development, it is essential that a blue/green corridor is established along the Chicago River system,” said Friends’ Executive Director Margaret Frisbie. “We have an opportunity right now to protect and connect the riverfront to provide quality habitat for wildlife and access for people all along the river’s 156 miles. Generations to come will have to live with the impact of decisions made today and we don’t want them to look back and regret it if we miss our chance.”
A blue/green corridor is a design solution that uses a river and adjacent lands to establish an interconnected passageway between natural habitats. Blue/green corridors protect and increase natural riverbanks, provide people with a place to play, allow for the natural movement of wildlife, and include µÚÒ»³Ô¹Ïopen space to absorb and filter rainwater using nature-based solutions.
On Thursday, µÚÒ»³Ô¹Ï also unveiled their new Public Land Natural Area Assessment Web Mapping Application that examined 147,158 acres of property within a half mile of the waterway on either bank. About 33 percent are public parcels, more than 37,000 acres are µÚÒ»³Ô¹Ïopen space, and 400 miles are natural shoreline presenting an enormous opportunity to create and connect healthy and accessible landscapes.
In the blue/green corridor study, University of Wisconsin-Whitewater researchers examined the assessed valuations of more than 123,000 properties along the Chicago River system in Cook County and applied a formula based on previous studies that looked at how using natural green infrastructure affected home values. These types of environmental efforts lead to an increase in residential property values of around five percent over 15 years, The Blue/Green Corridor: Establishing the Intersection Between Economic Growth and Environmental Design concludes.
Such blue/green corridor approaches have shown to have great economic value in other cities such as Houston, San Antonio, Washington, D.C. and others. Nature success stories include an escalation of fish species in Cleveland’s Cuyahoga River and a thriving wildlife of turtles, muskrats and great blue herons along Pittsburgh’s riverfront.
“Our research on the relationship between property value and environmental development has shown that individuals place value on natural amenities,” said report co-author Matthew Winden, Associate Professor of Economics at the University of Wisconsin-Whitewater and Assistant Director of FERC. “These amenities drive property value by improving the quality of life in the region through recreational and personal opportunities.”
