The County Official may modify or waive the requirements for planting and/or irrigation systems if he or she finds that said requirements would be unreasonable or unnecessary for any of the following reasons:
(a) the area is subject to periodic inundation,
(b) water is unavailable to the area such that irrigation would be impractical or impossible,
(c) the area is naturally devoid of vegetation, or
(d) the area consists of cut slopes which are not subject to erosion due to their rocky character or slopes which are protected with pneumatically applied concrete mortar or are otherwise treated to protect against erosion and instability to the County Official's satisfaction.
