Filling and and tearing up the whole yard is really pointless. You have a low point with a catchbasin and grate. Just pipe out of it downhill towards the parking area, put in fabric and drain rock along the way.
Grade it nearly flat. Storm water does not care about keeping a certain slope.
Keep digging until that pipe comes out of the ground. That is called daylighting.
if the soils are as you say, no water will come out of that pipe. It will all soak in.
If it did not all soak in, then anything left will run out of the daylighted pipe and the basement would never flood.
If you are not sure that it will daylight, assemble all your garden hoses and fill them until you can reach where you think it might be the same level or lower. Use the water level in the hose to determine the elevation between the two points.
This is a simple water level and is accurate as anything.
For a quick check, use a long level and sight down the top of it and take some measurements to the ground. This method is easier with help.
This solution requires a trench, some pipe, some gravel dumped on your parking area, and a wheelbarrow. The trench will heal back up after one season and you will not know it is there.
