I see the consultants point that people don't necessarily use their gardens
all year round but apart from this presumption no justification has been
provided except that the guidelines are derived from an exposure equation -
where the target value is in a linear relationship with the exposure
duration in days/years and the summer season is 4months.
The development includes private gardens and an area of proposed paving
which would in effect break the pathway within this area. However any
future owner of the property might change this area eg. into a veg. patch
in effect recreating the pathway.
