Intent
Intent 1: 
To limit the probability of the inadequate drainage of water from driveways, which could lead to the ingress of water into garages, which could lead to:
  • an inadequate control of the temperature of interior spaces, relative humidity, or water ingress and accumulation,
  • the generation of pollutants from biological growth or from materials that become unstable on wetting, or
  • deterioration, which could lead to compromised integrity of elements protected by the environmental separators.
This is to limit the probability of:
  • negative effects on the air quality of indoor spaces,
  • the inadequate thermal comfort of persons, and
  • contact with moisture.
This is to limit the probability of harm to persons.
