Whenever the director of public works determines and requires that a subdivider should install storm drainage facilities as a condition to the acceptance of a final map of subdivision and where, in the opinion of the director of public works and the council, the storm drainage facilities to be constructed can be or will be beneficial to property not in the subdivision and such storm drain facilities are dedicated to the public, the council may, by contract with the subdivider, agree to reimburse and may reimburse the subdivider for such storm drain facilities. The contract shall provide that the council may collect from any person using such storm drain facilities for the benefit of property not within the subdivision a reasonable charge for such use.
