This is what I can't understand. My yard didn't even get really soggy. My house backs up to Army Corps Property that houses a lake that is fed by two creeks. The lake rose about two feet but nothing even came close to flooding. No water on the roads...nothing.
But then 20 minutes south of me in Buckhead, you had four to five foot tall walls of water coursing through neighborhoods.
I guess I just don't understand how things flood and why they do and don't. Same storm, same amount of rain. I suppose it's topography on some level. Peachtree Creek isn't even that big...how did it get that much water in it?
That lake is effectively a giant drain for properties near it. If it filled enough, your property would flood. ACOE is conservative about keeping lake levels low during rainy periods, for this very reason. Lake Hartwell rose 6 feet in five days. That's over 50K acres. Lotta water.
Urban areas rely on sewers to carry water away, and sewers are never as robust as natural water ways like creeks and rivers.
