Rather than going for a “redesign” angle to the EC, I would be inclined to go for the safety issue. A cracked uneven driveway not only causes damages to cars but could be potential trip hazards for anyone walking down the driveway. We had someone fall on an uneven surface in my complex. With the resulting insurance claim, the insurance company made us make improvements throughout the complex that they thought was a safety hazard, not just the uneven surface in question.
And does this garden area pose a safety issue too? To either people or cars?
Has your complex had its 10 year sinking fund export done? Ours included a schedule for having our driveway resurfaced. Driveways are common property that need maintenance just like any other area of the complex. Perhaps because your side has fewer garages the majority of the residents don’t realize just how bad the situation is. We have had issues here where a resident complained about an area needing attendance, an area that only a few residents accessed. Hard to address an issue that you don’t know exists.
