Question Driveway design help? Civil engineers or architects C'mon in

Comments or suggestions on dimensions for off street parking / turnaround are welcome and appreciated.
Our new home is on a busy corner. Would like to have a turnaround somewhere between driveway and porch to be able to pull into driveway head-in, turnaround and back into garage so we can exit forward to the street without having to back onto a busy street. This turnaround could also serve as off-street parking for times when there's no street parking available for visitors.

I'm challenged to determine how close to house I may place the parking / turnaround pad. I'm figuring pad should be ~19' wide for two cars, wife may reduce it down to one car width. Basis for depth of pad is 195" car length (SS). Yes, it's a lot of concrete but it's less yard to mow.

Anyone able to help me figure out minimum distance from house I must place this pad to be able to back into either side of garage? I guesstimated 10', but not sure. Hope I described this well enough.

How far does your property go to the right of your garage?

10 feet. We're on a corner, we moved our driveway to the front of the house, it used to be on the side. To the right is a street that can get very busy, we're trying to stay away from there. There's also a fire hydrant, indicated by small circle with slash at bottom right. Driveway curve is to preserve a large tree that's indicated on the drawing, and the fire hydrant, too.

Garage door on back of garage as well, curved driveway to the other street. In or out from either direction, no reverse necessary.

Thank you, it's a good idea but...
We had to get our driveway off the street to the right, ingress/egress became challenging during certain times of day. Circular driveway would become a turnaround for merciless soccer moms in big SUVs.
Also, there's house behind the garage and a swimming pool behind that.

I've sort of got it figured, just not sure on how much distance from front of structure I need to do the V turn to back into garage. I could do some tests in the parking garage here, but thought a forum member may have keener insight.

I didn't figure my post to be very realistic, but it sounded great in my mind. If I'm looking at the schematic correctly it would appear that the turnaround will be on the left side of the garage as you face it. The truck driver in me is thinking that it would be easier to pull into the garage facing forward when you return home, and back into the turnaround when leaving. This way you are backing up "sight side" rather than blind side. Even in my cars I feel more comfortable reversing to my left, with both the side view mirror and any obstacles right next to me, allowing me to turn a much tighter radius. I'm sorry I can't really offer any help as far as the distance needed, but think your test idea is the most realistic approach. Sometimes calculations and comfort levels are two completely different things...

1- forget width of car with doors closed. DOORS OPEN so you can get in/out.

2- I learned from my neighbors' mistakes ... bigger is better. It will save you from saying "I shoulda made it wider ..."

3- I made my driveway cut way bigger too.

Good suggestion, hadn't looked at it his way.

Oh yes, totally considered width to allow loading/unloading, and space in front to walk to connector sidewalk for front walk.
