Permanent Stormwater Management

Traditionally stormwater management has involved the utilization of underground pipes in combination with detention basins for the purpose of moving water and then storing it temporarily allowing for filtration and controlled release over a period of time. The new Municipal Stormwater Permit calls for municipalities to modify their ordinances to allow for the implementation of extensive green infrastructure with an emphasis on infiltration (water absorbing into the ground), evapotranspiration (water absorbed and evaporated through plants), and rainwater harvesting (rain barrels, cisterns, etc). Following these changes, new and redevelopment projects will be required to manage the first inch of every rainfall on-site using these methods.

The Town of Farragut is currently reviewing codes, ordinances and policies to make these changes over the next several years.

Permeable Pavers and Bio Swale
Not only is McFee Park an exceptional destination for outdoor recreation in the Town of Farragut, it is also home to several contemporary water quality demonstrations for environmentally sensitive permanent stormwater infrastructure including: permeable pavers in lieu of asphalt, bio-swales instead of traffic islands and lowered curb all combine with aggressive landscaping to allow for optimal stormwater infiltration and evapotranspiration significantly reducing runoff and the potential to transport pollutants off-site.

Over the next five-year permit cycle, technologies like these will become more and more commonplace as municipalities modify their codes and ordinances to come in line with state and federal approaches to managing stormwater.
