In addition to any other fees provided for in this code, the village administrator, department heads, the planning commission and the chairmen of committees of the village board, along with other municipal officials who may be authorized from time to time to do so, with prior written notice to the administrator, may retain outside consultants with established expertise in disciplines necessary to evaluate applications for annexation, zoning, subdivision and construction to assist the officials of the village, its committees and the corporate authorities in processing applications for municipal action or permission. For purposes of this chapter, the terms "necessary or desirable" do not mean only such measures as are absolutely and indispensably necessary, but include all appropriate means which are conducive or adaptable to the end to be accomplished and which, in the judgment of the authorized official, will most advantageously permit the municipality to act upon the application or request.
