Casborran was reclassified into a town, independent of its mother town, Bolinao.

Casborran was attacked and destroyed by fire due to conflict in political and economic interests between the original settlers and the first migrants. Survivors fled in all directions but many of these former inhabitants soon returned to the ruins of the town.

The settlers tried to rebuild the town but another conflict made them leave town and relocate to Nansangaan (now Barangay Inerangan).

Inhabitants founded a new settlement on a plateau farther from the sea and was called Sarapsap (now Barangay Poblacion).

Alaminos, along with eight (8) towns of Northern Zambales were made part of the province of Pangasinan. Don Francisco Reinoso was elected and served as the first Municipal President.
