Under
the standard setting agencies regulations, the cost of providing an
accessible “path of travel” to the altered area is considered “disproportionate”
when the cost exceeds 20% of the costs of the overall alterations. When the
cost of providing an accessible “path of travel” is “disproportionate”,
the “path of travel” must be made accessible to the extent that
it can be done without incurring “disproportionate” costs and additional
alterations are made to the play area within three years of the original alteration,
the total cost of the alterations to the play area during the preceding three
year period are considered in determining whether the cost of making the “path
of travel” accessible is “disproportionate”.
