(A) any of the areas identified under subdivision (2) as not within the range of an existing or a planned siren; or
(B) any area identified under subdivision (1) as within the range of an existing siren, if the county legislative body determines that the existing siren does not provide consistent or adequate coverage for the area, based on the existing siren's failure rate, as determined under subdivision (1)(B)(vii).
