Carparks and General Storm drains when overflowing are not stagnant, therefore pose little risk to mosquito breeding. it's only still waters that are not boiling hot (e.g., a puddle in the middle of a concrete or macadam slab for parking) that provides the necessary breeding site for mosquitoes. bottle caps, kopi cups, styrofoam containers tossed under a bush somewhere and collect rainwater in the shade are perfect as are, of course, the usual suspects like the overturned bucket in the laundry wet area that has water collecting in the underside of the bucket lip, the water in the vase that hasn't been changed in a week, the plate under the bucket, etc. etc.
Sorry, but no, I don't see the difference. A little common sense would go a long way here. If you go on holiday for a month and left your home as a breeding ground, They would make a number of trips back to your abode at different times of the day/evenings and they would leave notices on your door. Repeated attempts where the notices have been removed but contact not made with their offices would probably result in more affirmative action on their part. Same with notices posted and not removed (e.g., left the country on hols). At some point in time they would get a court order to enter the premises, accompanied by the police. (But only if it was determined that your unit was the likely breeding ground.
