Substantial improvement.

Substantial improvement. Any repair, reconstruction or other improvement of a structure or facility, which has been damaged in excess of, or the cost of which equals or exceeds, 50% of the market value of the structure or replacement cost of the facility (including all public facilities as defined in the Disaster Relief Act of 1974) before the repair or improvement is started, or, if the structure or facility has been damaged and is proposed to be restored, before the damage occurred. If a facility is an essential link in a larger system, the percentage of damage will be based on the relative cost of repairing the damaged facility to the replacement cost of the portion of the system which is operationally dependent on the facility. The term substantial improvement does not include any alteration of a structure or facility listed on the National Register of Historic Places or a State Inventory of Historic Places. (See 44 CFR 59.1.)
