REQUIRING MULTI-HAZARD MAPS AND FLOOD HAZARD MAPS IN EVERY 
LOCAL GOVERNMENT UNIT AND FOR OTHER PURPOSES 
EXPLANATORY NOTE 
Six months after super typhoon Yolanda devastated numerous cities and 
municipalities, the Department of Science and Technology (DOST) and the Department 
of Enviromnent and Natural Resources (DENR) formally launched the Yolanda 
Rehabilitation Scientific Information (YORINFO) Center. The YORINFO Center collates 
all maps created by different government agencies, and creates multi- and flood hazard 
maps, These maps, which can go down to the barangay level, pinpoint areas which are 
most exposed to hazards, and which areas are the safest. These maps are an important 
tool for disaster planning, preparation, response, and rehabilitation. 
Despite the 
,significance of these maps, only 1 of the 171 Yolanda affected areas have requested for 
these maps. 
This bill aims to address this deficiency by requIrIng DOST and DENR to 
provide and educate all local government units on the value and use of these maps. 
Furthermore, it requires all local government units to disseminate the same information 
to all its barangays. This will enable local government units to improve their disaster 
response planning, preparation, response, and rehabilitation by basing it on scientific 
research and information. As such, the immediate passage of this bill is therefore 
requested.
