May 1, 2017 marks the 7th anniversary of a natural disaster that devastated Nashville, mourned 11 lives lost, saw $2 billion in damage, and ultimately brought our community closer together. Out of the rain that fell seven years ago – 13.5 inches in 36 hours – was born a greater resiliency, an engaged citizenry and stronger social cohesion.
The Department of General Services (DGS) works to integrate permeable pavers into new construction or building renovations, due to its commitment to sustainability and low impact development.
For instance, DGS added permeable paver parking surface at the Fulton Campus in 2012 during renovations.
Fulton Campus also features bioretention planting basins and allows General Services to showcase the best of stormwater controls to the development community as they come to the Metro Office Building campus to apply for permits for new projects throughout the Metro area.
This project consists of about 40,000 square feet of permeable pavers installed in one of the largest public installations in the State of Tennessee.
While the permeable pavers create a very attractive parking surface, they actually provide a very efficient means of reintroducing rain water runoff back into the ground, reducing the amount of stormwater that would otherwise flow through stormwater drainage systems back to the Cumberland River.
This installation replaced an aging parking surface of pervious asphalt. The Nashville Fire Department conducted a demonstration by releasing water in an isolated area to illustrate the infiltration rates of the permeable pavement system as a whole.
This exercise demonstrated how efficiently the paver surface is able to handle a large quantity of water with no runoff from the surface of the parking lot. It also showcased the structural capability of the parking surface, with its ability to support a large fire-fighting vehicle with a full load of water.
General Services was pleased to use this state-of-the-art low impact method to show its dedication to using sustainable means for stormwater management.
