LONG-TERM QUALITY AND CONSERVATION of Nashville's waterways demands enhanced stormwater practices and deeper public understanding and awareness. Fortunately in Nashville, numerous organizations are contributing to the conversation and creating momentum.

The Cumberland River Compact recently hosted a high-profile speaker series entitled Innovations and Solutions that focused on the most pressing environmental, legal, and political issues facing our local waterways. The series highlighted policies, regulations, and projects that will improve water quality and stream health.

Rebecca Dohn, Metro Water Services, previewed the upcoming 2016 policy changes that will require all new development projects to capture the first inch of rainfall on their sites. Benefits and incentives for this path are listed on the MWS website.

“This design methodology attempts to mimic a site's natural hydrology, which helps mitigate the impact of development on our waterways,” said Dohn.

Civil & Environmental Consultants' Steve Casey, discussed a recent stormwater upgrade project to improve the water quality of Cathy Jo Branch, a small headwater stream flowing through the Nashville Zoo. The project, conducted in collaboration with the Zoo and the Cumberland River Compact, has improved water quality for the stream, removed six acres of invasive plants, and created a new exhibit space of native grass prairie for elk and bison.

Through collaboration, education and action, the Compact's goal is to ensure clean and abundant water sources that support life, recreation and economic well-being for generations to come. To learn more about the Cumberland River Compact, visit http://cumberlandrivercompact.org.
