The city of Smyrna has a good Internet presence, but I have felt it lacked in links. I thought a few of the city pages may hold some interest to you.
There is the general download page. Loaded with PDF's of subdivision regulations. zoning ordinances, and business license application, plus many others. A lot of the downloads you need can be found here.
Have a need to request public work? Giant tire crushing pothole on your street? Is the street drain in front of your house backing up..even when there is no rain? Is trash being dumped regularly on a back road near your yard? You can go to the city public works online request form to submit a request.
I recently found a Smyrna website called "Come to Smyrna, Tn". Run by Kendra Cooke of Crye-Leike Realtors it has some nice material on it.
Want the latest news on good BBQ and the people who celebrate it? the Heritage BBQ festival's website has that and more.
