Ever think of piling up a been? A speed bump high enough you don't need the floodgates, that you can drive over. I don't literally have that, but there's a high sidewalk to drive over and my lot is downhill.

Yes, speed bump your driveway.
That's what I did. I have a pipe I can open if needed to drain my lot, but it won't come up my driveway and flood my sheds anymore. My street becomes a river about 12" deep if it rains 2 inches in an hour or so. But first, I had to put the berm around a chain link fence on one side of the property. On that side, the street water would run up the neighbors driveway, and then flow through my yard, and back out to the street.
About 150 foot long, two feet high berm. Took me about 5 years of recreational/therapeutic digging workout program to make the berm. The place the dirt came from now collects all my run off from the 1/3 acre, and is where I have the lawn. Once that went in, I could put a hump in my driveway.
The bump idea was looked into. I even had the town out to look at what I had to do to stay friends with them.
However, if you look at the photos, there's really no way a bump into the driveway can control that much water.
We're talking literally millions of gallons of water. And a strong enough current to take you right off your feet...I know.
And I would have to have, a minimum of 1.5 ' high berm. No car can get over that unless its a rock climber. I would have to fill in and slope it halfway to my garage. The wakes and splash from the vehicles throw water over three feet high into my yard. So it would be of little use and be unsightly as well. I did put a berm on the right side, just before the intersection. The water has yet to reach the top at any point along that berm.
Nothing like experience
I've been monitoring this for over twenty-five years, so I'm somewhat of an expert when it comes to my home and surrounding street. I even had an engineer try to tell me how the floodwater flows. He had his maps and everything.
I can tell you this. There are basically three flood levels here. Mini, Major, Massive. The photo's for the 2010 flood would be a category Massive. Usually, we have mini's, or maybe a mini-major.
I lived here, I've seen and I've learned. I never did see anyone from the town out here checking to make sure the water flowed where they said it is supposed to. He was what my stepdad used to call, " a book-learned idiot". The man had absolutely no concept of what really happens during a flood situation, regarding my home and street.
On the left side, I have a two-block high retaining wall along my chain link fence. It's there so worst case, the water can't come around the end of my front block wall and back into my yard, which it has done. The problem with that is, it also keeps water in. So I've made sure it channels to the back part of the yard, and empties out there. Sorry neighbor. But the amount is much less than what it would take to flood his yard. Most of it stays on the easement road.
But it's all good since I built my flood gates. They have relieved me of a lot of stress.
If I'm going to be away for any period of time, I make sure they are closed.
This summer or sooner now, I plan on replacing them with a better metal swing gate system.
Just the other night I was looking for 'rising hinges'. I want to use them so that when the gates close, they will drop down and help seal the bottom. Easy peasy.
