In not less than thirty nor more than ninety days after the passage of the resolution referred to in section 4957.02 of the Revised Code, the legislative authority of a municipal corporation or the board of county commissioners shall determine whether it will proceed with the proposed improvement. If it is decided to proceed with the improvement, an ordinance by the legislative authority or resolution by the board shall be passed, which ordinance or resolution must contain, in addition to the conditions stated in such resolution, the plans and specifications of the proposed alteration and improvement, a statement of the damages claimed or likely to accrue by reason of it, how the payment of such damages is to be apportioned between the municipal corporation or county and the railroad company, and who shall supervise the work of construction. Upon the acceptance of this resolution or ordinance by resolution by the company through its board of directors, it shall constitute an agreement, valid and binding on the municipal corporation or county and the company respectively. Such agreement shall be filed in the court of common pleas of the county in which the crossing is located for entry upon its records, whereupon it shall have the same effect as a decree of the court.
