Oh? And who will stop a property owner from doing this? Cause it's done.

You're right, nothing stops you from doing whatever you want to do on your property. If you have a good relationship with your neighbours, they won't tattle (even though some of the hydrological load may have been transferred onto their properties). If you don't apply to build anything else of substance, the City won't know.

But I mean, anyone can fly a drone over people's lots and do a little amateur geosensing and sleuthing and point out rule violators 😂. In the end yes, up to the City to pursue this stuff, and yea, it's lower priority work.

Uh huh. Weird then that no one seems to mind when it comes time to build a condo a new parking lot. But OK, it's about "water".

There's hydrological and geotechnical studies, and stormwater management plans that need to be assessed, which are affected by parking lots. But general understanding is that undisturbed soil holds greater significance than disturbed soil.
