SUMMARY REPORT - MGB Region III

adjacent barangays and municipalities. Backflooding results from the inadequate
drainage and exit points during unusually heavy rainy day and typhoon periods.
Structurally controlled flooding such as elevated roads and road system with
insufficient drainage, irrigation canals and excessive release of water from dams
and temporary water impoundments are also common factors.
• The agricultural areas/farm lots have a moderate to high susceptibility to flooding.
• Localized flooding that usually subside after the rains can be attributed to
inadequate drainage system during periods of unusually heavy precipitation.
28. Municipality of Zaragosa
• In terms of landslide susceptibility, no barangays in Zaragosa have the
potential for landslide occurrence.
• There are seven (7) barangays with moderate to high susceptibility to flooding
(San Vicente, Carmen, Pantoc, Concepcion, San Isidro, Sta. Cruz and San
Rafael).
• There are twelve (12) barangays with high susceptibility to flooding. These
barangays have portions that are adjacent to active creeks and river channel
and are generally located in the low-lying areas (Sta. Lucia Young, Sta. Lucia
Old, Del Pilar, Sto. Rosario Young, Sto. Rosario Old, Macarse, Mayamot,
Veleriana, Batitang, Manaol, H. Romero and Gen. Luna).
It should be noted that these susceptibility ratings were arrived at as of the field
assessment. However the rating could advance (e.g., from low to moderate, moderate
to high) due to changing physical conditions. Hence, the MGB constantly recommends
strict and continuous monitoring of the affected barangays.
Attached herewith are the matrices of the municipalities included in the assessment.
The geohazard assessment in the municipalities of Cabiao, Jaen, San Antonio and San
Isidro was conducted in 2004-2005 during the Hazard Assessment along the Pampanga
River. The location of the barangays was included in the geohazard data base. The
data collected during this period was incorporated in the 1:50,000 Flood Susceptibility
Map of the Province of Nueva Ecija.
The hazard maps of Cabanatuan City and Palayan City was initially prepared by the
MGBCO-UNDP 2005 and updated during this hazard mapping and assessment project.
The location of the barangays was included in the geohazard data base. The data
collected during this period was also incorporated in the 1:50,000 Flood Susceptibility
Map of the Province of Nueva Ecija.
