The Harrell Road Park project converted an abandoned tract of unbuildable land into a public-serving, naturalized park. The 15-acre site is located in Knox County and was donated to Legacy Parks Foundation who came to Design Center for assistance. The ETCDC volunteer professional adviser was Patrick Beasley, ASLA.

Once the construction was completed, Legacy Parks donated the sustainable park to Knox County. The site has a pond, kayak access to Beaver Creek, low-lying wetland areas, and a wide variety of wildlife and consists of both naturally occurring and man-made wetlands, lowlands, and ridges.

This park will demonstrate ways to effectively manage stormwater, the first such park in this area. As water enters the site it is slowed and held back by check dams, allowing the plants in the rain gardens to filter nutrients, sediments, and pollutants out of the water before it enters the stream or pond. Constructed wetland areas allow for further holding capacity of runoff and provide an opportunity for water to collect, provide habitat, and recharge local aquifers. As the first stormwater park in this area, it serves as a teaching tool for other sustainable development.
