Citing for the potential of the area for settlement and agricultural development, President Quezon declared the entire land area of Mallig Plains as project site for his program on rural development. In support of this declaration, he created the Office of National Land Settlement Administration which was renamed to Land Settlement Development Corporation (LaSeDeCo). Subsequently, this corporation was reorganized. At that time, the primary objective of LaSeDeCo was basically to oversee and facilitate the distribution of lands to qualified settlers. With the development of this opportunity for rural and agricultural development and with the completion of the Balete Pass Road in the 1920s that runs through the hinterlands of the Caraballo Mountains, hundreds of inhabitants from the Ilocos and Central Luzon regions opted to settle and avail of the program of the government in the Mallig Plains area.
