Click http://noah.up.edu.ph/#/  for DOST's Project NOAH where we can see the FLOOD HAZARD for your area. We recommend to consider this in designing the elevation (how high your house / building will be) of your house / building.

Step 1: Click the icon for flood. It is the 3rd icon that looks like this. 
 

Step 2: Click Flood Hazards
 

Step 3: Input Desired Region, Province/District, Municipal, Return Rate

              Tip: if you don't know the Region or District, just do trial and error as the area/municipal will appear. Also input 100 years for the Return Rate to get the worst situation in 100 years. 
 

Step 4: Check your area if it is flood prone using this legend.
