GROUNDS FOR EXCLUSION.

Exclusions from the district may be made on the grounds that:

(1) to retain certain land or other property within the district's taxing power would be arbitrary and unnecessary to conserve the public welfare, would impair or destroy the value of the property desired to be excluded, and would constitute the arbitrary imposition of a confiscatory burden;

(2) to retain any given land or other property in the district and to extend to it, either presently or in the future, the benefits, service, or protection of the district's facilities would create an undue and uneconomical burden on the remainder of the district; or

(3) the land desired to be excluded cannot be bettered as to conditions of living and health, provided with water or sewer service, protected from flood, drained, freed from interruption of traffic caused by excess of water on the roads, highways, or other means of transportation serving the land, or otherwise benefited by the district's proposed improvements.
