The Cumberland River Compact is working with neighborhood associations in the Browns Creek watershed to plant rain gardens on private residential properties this spring. The gardens will be planted by volunteers with plants provided by the Cumberland River Compact with no charge to home owners. Homeowners will be required to maintain the garden with seasonal watering during the first 2 summers and occasional weeding. We have funding for up to 25 gardens in the 12 South Neighborhood. This project is April 15 - 28 with a mandatory informational meeting Wednesday March 29 at 6pm at the Sevier Park Community Center. We will also start a waiting list for fall 2011 rain gardens should demand exceed 25.
A rain garden is a small bowl shaped garden, 6" deep, designed to catch rain water runoff from roofs or driveways. The garden holds the water for less than 24 hours giving it time to sink into the ground. It is planted with native flowers and ornamental grasses.
While residential communities are doing what they can to assist the stormwater treatment process, ultimately the largest impact on the Brown's Creek watershed are the industrial and business developments and the impervious surfaces of highways, parking lots, and surface roads. Ultimately, cleaning up Brown's Creek is going to be a much larger project, for which rain gardens are an initial step.
