The PSA is working with the WWF Philippines to assist Santa Rosa in the development of their Urban Drainage Master Plan. The Sangguniang Bayan of Santa Rosa, in SB Resolution No 152-2009 dated May 25, 2009, requested the Local Chief Executive through the planning and engineering offices to formulate a comprehensive drainage and sewerage master plan for the City. The LGUs of Cabuyao and Binan, in separate meetings, likewise indicated interest in formulating a Drainage Master Plan. Since the political boundaries of Binan and Santa Rosa are demarcated along the Santa Rosa River, and that of Santa Rosa and Cabuyao are demarcated along the Cabuyao River, the 3 LGUs are convinced of the need to integrate their respective master plans.
