The Nashville Metropolitan Government West Park Equalization Facility earned the Institute for Sustainable Infrastructure Envision Platinum award. The project is the first joint wastewater and park project in the United States to receive an Envision rating award.

The project’s inter-agency collaboration provides two different community benefits: valuable park improvements and cleaner rivers and streams.

The design of the Nashville Metropolitan Government West Park Equalization Facility revolved around finding a way of eliminating unpermitted discharges from its wastewater collections system and accommodating updated flood zones following historic flooding in Nashville in 2010.

To meet these goals, the project relocated to nearby West Park. By relocating to the park, the project could build wet weather wastewater storage systems, avoid having to build a costly second tank at the original location, and use savings to fund needed park upgrades and new recreational facilities. The project provides new public space, which includes a walking trail, a modern playground, a pavilion for public use, and a “pocket” urban forest.

This project also enhances surface water functions by improving the hydrologic connection through increased infiltration and riparian buffer preservation. The project increases biodiversity with the addition of six new native species of trees to the riparian area of Richland Creek. By reducing materials used and adding trees, the design reduces carbon emissions by more than 40 percent over the life of the project.

The project was designed by Hazen and Sawyer and Nashville Metro Water Services in collaboration with Metro Nashville Parks and Recreation.

The ISI Envision rating system measures sustainable infrastructure projects in five categories: quality of life, leadership, natural world, resource allocation, and climate and risk. Learn more about Envision and ISI at sustainableinfrastructure.org.
