In 1964, a report produced by the Tennessee Department of Public Health stated that the Chattanooga Creek was “without a doubt, the most grossly polluted stream in the Chattanooga area.”

In 1969, the Department of Health, Education and Welfare determined that Chattanooga, Tennessee had the poorest air quality in the nation. This was due, in large part, to a heavy manufacturing industry that included chemicals and pesticides.

Many cities have faced these same challenges. Many cities still do. But Chattanooga’s responses and solutions have been unique, and very successful.

One of the first things the city did was create, and have approved by the state, the Hamilton County Air Pollution Control Bureau. The Bureau was charged with establishing air quality regulations for the city. In an effort to ensure compliance of these regulations, the Bureau worked directly with the manufacturing sector. At the time, the primary need was for smokestack “scrubbers”, which remove most of the toxic by-products typically released by industrial smokestacks.

The manufacturing sector responded quickly and creatively. Not only did they agree to the $40 million in renovations that was needed, but local entrepreneurs chose to build the scrubbers in town. Today the scrubbers are still being manufactured, and are being exported worldwide. Thus, a profitable industry was created, while simultaneously improving air quality.

The city began holding “community visioning” meetings, seeking resident assistance with the environmental and economic troubles it was facing. One outcome of those meetings was the creation of the Moccasin Bend Task Force. This task force studied the 22-mile long Tennessee River and, with the input of hundreds of local citizens, developed the Tennessee River Park Master Plan. The Master Plan eventually resulted in the development of a 23-mile River Walk. The city maintains it through a yearly River Rescue clean-up effort, and it has enabled Chattanooga residents and tourists to enjoy the river again. The Master Plan didn’t just focus on the banks of the Tennessee River. It also included strategies for cleaning up and beautifying the banks of the creeks that feed into the river. In addition, a water treatment facility was built farther upstream, to aid in purifying the streams and lake. Now, where “no swimming” signs used to be the prominent feature, you can instead see people swimming, boating, or simply walking along the river’s edge.

From the river, the environmental revitalizing moved to the downtown district. Trees were planted along the streets. Not just for aesthetic purposes, but to help reduce pollution. The trees are purchased from a local, private nursery. Street pavers were built to help reduce the effects of storm water run-off. Air and traffic pollution have been reduced with the introduction of an electric mass transit system. The technology and vehicles were developed and built locally, and are now being exported globally. People who work downtown can park in garages at the edge of the downtown district, then take electric shuttles to their final destinations. The money generated from the parking garages helps cover the cost of the electric vehicles.

One of the most aggressive and innovative projects is the South-Central business district. Being built as an eco-industrial park, the goal is zero emissions. This means that the waste products from one industry become resources for another within the district.

Chattanooga has excelled at developing a sustainable community, because it has re-integrated the human element. At the heart of most of its initiatives has been the Chattanooga citizens themselves. The community vision meetings were the cornerstone for most of the changes that have been made. But the citizens don’t just offer ideas, they help implement and maintain them. This is done, not only through clean-up efforts like River Rescue, but also through everyday activities. The Orange Grove Recycling Center is a perfect example.

Though it could use machinery to separate the recyclable materials that come in from the nearly 60,000 homes and municipal drop-off sites, the Center instead employs about 100 developmentally disabled adults. Not only does manual sorting reduce industrial pollution, but it also gives an often-ignored part of the population a sense of purpose and belonging. The workers are paid for their time, and are given the opportunity to become and integral part of this community’s sustained environment.

Chattanooga Neighborhood Enterprise was yet another result of the community vision meetings. It is currently creating a mixed-use, mixed-income development in a part of downtown Chattanooga’s Southside district. Included is an elementary school that will allow children in the area to walk to school for the first time in years.

While most cities, nationally and globally, make an effort to reduce negative affects on the environment; few (if any) have attained the level of success enjoyed by Chattanooga. Here, industry is not the enemy, but instead has offered viable and effective solutions. Here, the citizen and the government official aren’t at odds. Rather, they work together to creatively address the environmental challenges the city has faced.

Chattanooga has become one of the few cities designated as an EPA attainment city. This has been due, in large part, to combined efforts of Chattanooga citizens and city officials.

From “most polluted city in the nation” to one of the best (possibly the best) models of an environmentally healthy and sustainable city, in under 40 years. Not bad.
