Streamside Buffers
In 2007, Murfreesboro established a Water Quality Protection Area (WQPA) policy and ordinance. This policy requires that any new land development alongside a stream should establish a 35 or 50 foot buffer, depending on the size of the stream. Residences built in or after 2007 and are located next to a stream, the yard is most likely platted with a WQPA. This is a protected area, a no-touch zone with few exceptions. Residents are not allowed to remove vegetation, do earth work or construction, or apply herbicides. More information about buffer regulations are provide on this site. The page also notes that 60' wide buffer instead of a 50' wide buffers are required on stream segments where the watershed area is 640 acres or more. This map depicts the 640-acre drainage points.

Green Alley Project
The Cumberland River Compact’s Green Alley project is transforming alleys from asphalt stormwater conveyances that transport pollution to our most vulnerable streams into areas that percolate and clean polluted stormwater, thereby improving water quality throughout the city.

Rain Barrel Sales
A rain barrel is a system that collects and stores rainwater from the rooftop that would otherwise be lost to runoff and be diverted to our neighborhood streams and storm drains. You may be surprised by the amount of water you can harvest: one inch of rain on 1,000 square feet of rooftop creates over 600 gallons of water!  Purchase a rain barrel or learn how to build one! Additional information on this page about what a rain barrel is, how to build one, and safety considerations. 

Rain Gardens
We work with the public to build rain gardens in yards, at schools, churches, parks, and businesses. Rain gardens can capture and percolate tens of thousands of gallons of stormwater a year. This prevents the transport of pollutants into our waterways. The Cumberland River Compact hosts classes, offers site visits, and organizes volunteer groups to build rain gardens. We have built close to 500 rain gardens in middle Tennessee. The Rain Gardens for NashvilleGuide is available from this webpage. 

Stormwater Management Retrofits
Because our understanding of urban water pollution and stormwater management is always improving, the Compact embraces opportunities implement state of the art technologies. Most recently a Compact project redesigned a Nashville Zoo detention pond with native species, berms designed to maximize infiltration, flow velocity control structures and a layered use of space that will soon accommodate a grazing elk exhibit.  This retrofit of existing stormwater management provided the engineering community with examples of environmentally progressive practices for preventing urban water pollution and restoring the health of our urban streams for people and for nature.

Stormwater Model
The stormwater model allows children to learn about how urban development, if not properly managed, can contribute to flooding.  The Compact provides demonstrations of this interactive, kid-friendly model at many of our annual events, and also provides demonstrations throughout the summer in Cumberland Park.

Street Trees
The Cumberland River Compact plants hundreds of trees every year – big trees and seedlings – along roadways and streams. Trees are the least expensive, most impactful tool we have to improve water quality. Information about this program and how-to guide for planting seedlings, watering, and best times to plant are available on this webpage. 

Sugartree Creek Restoration
The Cumberland River Compact and its partners, Metro Water Services and the Nature Conservancy, Tennessee Chapter are working in Sugartree Creek to establish a model for urban stream mediation. The goal of our project is to implement newly designed EPA software that determines optimum locations for water quality projects and apply this to Sugartree Creek.
