A concurrency determination by the department creates a rebuttable presumption of validity. The hearing examiner may vacate a concurrency determination upon a showing that the determination is clearly erroneous. The department of public works’ professional judgment and expertise shall be entitled to substantial weight. The party challenging the concurrency determination shall have the burden of proof.
