Storm water drainage

Topmix Permeable is a fast draining concrete pavement solution that rapidly directs stormwater off streets, parking surfaces, driveways and walkways. This minimises the cost and long-term maintenance for local authorities and developers of stormwater management.

Don't know how this would work for major flooding, It soaks up the water, and drains it off into groundwater.

1. There are a few parking lots in our city paved with that, or something similar.

Parking lots and industrial/retail roofs are no longer allowed to drain directly into storm drains or waterways. New developments are required to drain the water into infiltration basins or similar. In some cases these are large perforated cisterns underneath the parking lot.

2. Well, that was amazing!

But I see a problem with flooding IF the groundwater is already soaked to capacity.
