To restore the small-scale damage of the agricultural infrastructure in the Mid-Niigata Prefecture Earthquake in 2004, the government of Niigata Pref. created the Small-scale Disaster Restoration Project (SDRP: In Japanese 'Tezukuri-tanaoshi-tou-shien' Project) funded by the Emergency Restoration Fund. The principal mission of this project is to complement the Disaster Restoration Project (DRP) that targets damage with a certain scale or more. In this research, by comparing the number and the details of the damage restored by the SDRP with those restored by the DRP etc., the following characteristics that a large-scale infrastructure disaster brought about were clarified: 1) There were cases of small-scale damage as many as large-scale ones. 2) The small-scale damage occurred at a higher rate in the hilly and mountainous area, and gave rise to a greater impact on the disadvantaged areas. 3) The patterns of the large-scale and small-scale damage differ. In addition, the contributions of the SDRP were evaluated with respect to the facts that the following cases could be accommodated by the SDRP: 1) Restoration of roads and waterways managed by the limited members. 2) Restoration of the damage discovered some period after the occurrence of the earthquake. 3) Restoration of the damage which could not be accommodated with the existing projects.
