By late 2014, then-MMDA Chairman Francis Tolentino proposed that San Pedro, Laguna be included in Metro Manila as its 18th member city. Tolentino said that in the first meeting of the MMDA Council of mayors in January 2015, he will push for the inclusion of the city to the MMDA. Senator Aquilino "Koko" Pimentel III filed Senate Bill No. 3029, which seeks to create San Pedro as a separate legislative district to commence in the next national and local elections if the bill was passed into law.
