Limit paved surfaces.

Ensure that your downspouts drain to vegetation, gravel, or rainbarrels, rather than pervious surfaces, which contribute to polluted stormwater runoff. If you constructing or repairing your driveway, pervious pavement allows stormwater to infiltrate and filter through the ground. If you can’t do the whole drive, consider making only the portion closest to the street pervious. Lead can often leech from old car batteries, so this is essential to protect the local waterways. 

The resources and organizations below may be able to help you with this mitigation strategy and/or to learn more.

Smart Yards Program
Tennessee Smart Yards is a University of Tennessee-led program that guides and assists Tennessee residents and neighborhood associations on practices they can apply in their yards and common spaces to create healthier living spaces and communities. Courses aim to help homeowners achieve a landscape that reflects their values, desires and needs, while ensuring the protection of our state's waterways. Water related principles of a smart yard include using water efficiently, using fertilizers appropriately, reducing storm water runoff and its pollutants, and potecting water's edge, amongst others. Check out the Smart Yards yardstick for a check list of mitigation activities associate with smart yard principles.

Green Infrastructure Design Guidelines
This manual presents an overview of the principles of Low Impact Development (LID) and how it mimics the way nature handles water. It examines why protecting water quality is so important, the costs of conventional practices, and the benefits of sustainability. Intended for use by designers, developers, agencies, and individuals, it offers a brief look at frequently used LID techniques with descriptions, estimated cost factors, and typical maintenance requirements. The appendices offer specific information, advice, and costs for each component.

Stormwater Management Manual Volume 5 - Low Impact Development
The Low Impact Development (LID) Manual is a site design approach that utilizes Green Infrastructure to meet a development site’s post development stormwater runoff water quality requirements. This approach satisfies the new MS4 Permit requirement to infiltrate, evapotranspire, or harvest and use the first inch of rain. Topics covered include: BioretentionUrban BioretentionPermeable PavementInfiltrationWater Quality SwalesExtended Detention PondsDownspout DisconnectionGrass ChannelsSheet FlowReforestationCisterns, and Green Roofs. Additional LID resources and information are available through Metro on this webpage, including a table of incentives for Green Infrastructure, an LID Site Design Tool, and a cistern design tool. Metro also offers this LID Manual Training Video to introduce manual methodology and describe how to build a site according to the manual, manual training slides, and an interactive map of LID sites in Metro Nashville.

Cumberland River Compact
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.
