Any person may apply to the board to investigate the facts stated in any specified notice so filed and to state in writing its determination of the facts found by it upon such investigation. The cost of such investigation and determination shall be paid by such applicant by such deposits or in such payments as may be fixed by the board. In the event the board makes a determination which differs in any material respect from the facts contained in the notice, then, prior to making its final determination, the board shall notify both the person filing said notice and the person requesting a determination of facts of its proposed findings, and shall invite either party to submit further information prior to making its final determination, and no such final determination shall be made until sixty (60) days after the parties have been so notified of the board’s proposed determination.

In any action or proceeding hereafter pending in which the facts, or any of them, contained in the notices so filed are material, such notices shall not be evidence of any fact stated therein, but such determination by the board shall be prima facie evidence of said facts.
