During the 1970s, less land was available for sugarcane since planters sold their land to developers or converted them into subdivisions. Profit of the mill was decreasing. The Yulo family realized a need for a comprehensive master plan for the estate. They sought the assistance of National Artist for Architecture Leandro V. Locsin, married to Cecilia Yulo-Locsin, and the Canlubang Urban Project was born. Locsin designed Canlubang as a pioneer sustainable satellite city to attract investors in Laguna. In 1972, the first integrated industrial park was built outside Metro Manila. Canlubang became the catalyst of what is now known as Project CALABARZON.
