Intent 1:
To limit the probability of an excessively high
height-to-thickness ratio, which could lead to an inadequate resistance
to expected wind loads.
This is to limit the probability
of:
- compromised structural integrity of parapets, or
- cracking of masonry or mortar, which could lead to excessive
water ingress into the parapet, which could lead to the deterioration
of elements in or below the parapet, which could lead to compromised
structural integrity.
This is to limit the probability of damage to the building.
