ᐅ Letting Rainwater Infiltrate the Ground – A Cost-Effective Solution?

Hello everyone,
I am looking for an affordable way to prevent our rainwater from flowing onto neighboring properties and to avoid unnecessary disputes with neighbors.
Regarding our specific situation:
Brandenburg, property size only 440 m2 (4736 sq ft), single-family house with a pitched roof. After subtracting sealed surfaces, about 250 m2 (2691 sq ft) of garden area remain, where the water should theoretically infiltrate. A rainwater cistern is not mandatory for us.
After some research, I have read that a cistern is only worthwhile for larger properties. Since we plan to have just some lawn and possibly a small flower bed on the property, but no additional trees, hedges, or shrubs, we consider a cistern unsuitable in our case.
We also do not want to create water basins due to the risk for children and potential mosquito breeding.
At least, we plan to build the driveway to the carport with a "bound gravel surface," which offers some water permeability.
Now to the question: Does anyone have similar property conditions or other practical, cost-effective ideas to prevent our rainwater from flowing onto neighboring properties during very rainy periods?

To store water, it would definitely be worthwhile to green the carport roof, and permeable paving is also a good idea. Although, with that type of soil, it doesn’t really help much. You would need to have 6m (20 feet) of clay underneath, then the water would drain away. I would look for a tree that can tolerate the soil; its roots will then grow through and loosen the ground, helping the water to infiltrate better.

A cistern is not suitable for our individual case. Yes, of course!

We installed a concrete soakaway chamber. That is exactly the optimal and affordable solution if there is no other space available. It is also accepted by the authorities: the size is calculated, the excavator installs it, and the downpipes are connected. It cost us about 3,000 to 5,000.

What would be the downside of using two rain barrels (decorated, so not the plain green ones), possibly equipped with a tap, so that the water can occasionally be used with a hose for lawn irrigation after a day of rainfall? They only collect water locally and cannot handle longer rain events due to limited capacity. They are also not accepted for official purposes.

Silly question, aren’t you allowed to drain the rainwater into the sewer system?Why would you do that? You have to pay for it, right? And besides, it unnecessarily burdens the wastewater treatment plants.
If you have the option, it's better to pay a little extra (it's not much where we are) and then you have peace of mind. It's not about regular rain, but heavy rain, ideally when the ground can't absorb any more water.
@tomtom79 You’re not allowed to? In the new development area being built here, retention space must be provided—mine is 5 cubic meters (about 176 cubic feet). The rest can be drained away. This is because the downhill sewer system can't handle the rainwater. There, the manhole covers tend to lift during heavy rain, seemingly always has been like that.
