FLOOD HAZARD MAPPING TRAINING COURSE
JFY 2008
1Background of the proposal

I. Introduction
This report pertains to the application of the training program conducted in Japan
entitled “Flood Hazard Mapping for Asian Countries” from October 26, 2008 toNovember 29, 2008 to the City of San Fernando, Pampanga, Philippines.
The training program was sponsored by Japan International Cooperation Agency(JICA) as part of the Official Development Assistance of the Government of Japan
based on bilateral agreement to the Government of the Philippines.
The main objective of this course is to acquire knowledge, technology and experienceon how to make, disseminate, and utilize the Flood Hazard Map in Japan andformulate an action plan by applying the knowledge and ideas acquired anddiscussed in Japan among the officials and engineers who engage in the flood andriver management in the City of San Fernando, Pampanga.
II. Rationale
Due to the geographical location of the Philippines, the City ofSan Fernando (P) is also vulnerable to natural hazards liketyphoons, flooding, earthquake and volcanic eruption. The
Philippines is experiencing 20 typhoons a year of which 5 aredestructive, and much human life and property are lost by flood,and it is predicted that population in urban area will rapidly
increase in the near future and vulnerability to flood also
increase.
Flooding in the City of San Fernando (P) is aggravated by the sediments depositedby Mount Pinatubo in our streams and high intensity of rainfall brought about bystrong typhoons. In order to reduce the damage caused by flood and vulnerability,structural countermeasures like embankment with slope protection and retarding
basin are very effective. On the other hand, nonstructural countermeasures like “Flood Hazard Maps(FHM)”, which can offer the information including thepast inundation record, anticipated inundation area,evacuation route, evacuation place, etc. to residents, arealso important. Especially in local government units
Capitol Blvd.
with undeveloped structural countermeasures, it is2

helpful to take non-structural countermeasures immediately like making floodhazard maps, implementing proper waste disposal, regulating informal settlers
among others. Related to this, I am proposing the application of Flood Hazard Mapsin the City of San Fernando (P).

Project Proposal

A. Project Title
Flood Hazard Mapping in the City of San Fernando, Pampanga

B. Project Description
The project will have three (3) phases
1. Phase I: Cascadinga. Action Plan
The knowledge, technology and experiences acquired in Japan inmaking, disseminating and utilizing FHM will be cascaded among theofficials and engineers in the city government who engage in the floodand river management.
b. Description
There are very few in my country having
adequate knowledge about the Flood Hazard
Map. Hence, first of all, I would introduce theFHM in my organization. The technology,
knowledge and experience in Japan in making,disseminating and utilizing FHM will becascaded among the officials and engineers in the city government who
engage in the flood and river management by conducting meetings or
joining other meetings of various offices as guest speaker to introduce3the importance of FHM. In that way we can save time and resources inintroducing the FHM.
c. Duration
One (1) year from January 2009 to December 2009
d. Participants
City Officials and attached Agencies
e. Objective
To cascade the technology, knowledge and experience acquired inJapan and shared among the City Officials and attached Agencies whoengage in the flood and river management.
f. Scope
Summary of the training program Flood Hazard Mapping for AsianCountries in Japang. Budget12months X 50persons X P500 = P 300,000.00

2. Phase II: Productiona. Action PlanPrepare a project proposal for approval.
b. DescriptionFormalize the production of FHM by seeking approval from the Local
Chief Executive and secure a legal basis in producing, distributing andutilizing the FHM by requesting the City
Council to sponsor and enact a law (cityresolution or an ordinance) for the production,dissemination and utilization of FHM in the city.
The project cost will then be incorporated in theAnnual Investment Plan (AIP) for the next year
in order to comply with the Government Procurement Law. A good
example of good production of FHM is in Tokyo City wherein the FHM4

is a product of the collaboration of the concern authorities andstakeholders.
c. Duration
One (1) year from January 2010 to December 2010
d. Participants
The city government, stakeholders, experts and media.
e. Objective
To produce flood hazard maps through proper channel by following

production and implementation of the proposed project.
f. Scope
Data collection, expert consultation, inundation analysis, publicconsultation, evaluation, finalization and printing
g. Budget(P3, 000,000.00)

3. Phase III: Utilizationa. Action Plan
Request the assistance of the Multi Sectoral Governance Council(MSGC) in educating, distribution, dissemination and utilization of theFHM in the city.
b. Description
The MSGC or Multi Sectoral GovernanceCouncil is an organization that represents
various sectors in the society: academe, religious,transport, business, medical etc. The MSGC canhelp in distributing, educating, disseminating
and utilizing FHM. To make the people aware of
their responsibility as good citizen of the society we need to respect
mother nature, learned how to co-exist with environment andacknowledge the importance of sustainable development.
5c. Duration
One (1) year from January 2011 to December 2011
d. Participants
The entire population of the City and Consultantse. Objective
To educate and utilize FHM in the city, to learned from the flooding
experiences in the past, to be aware of the city present hazard
situation and be prepared in any eventuality in the future.
f. Scope
Education, dissemination, distribution and utilization of FHM
g. Budget(P3, 000,000.00)

Flood and Inundation

Though countermeasures for flood control and storm
drainage improvement have been conducted in the cityof San Fernando for the last 10 years, frequency offlooding and inundation are still high. The flooding andinundation problem experienced in the city proper of
San Fernando can be attributed primarily to theinadequate capacity of river,creeks and drainage system
to accommodate the excess
run-off from Angeles area and Mexico area. Likewise,
the change in land topography by the eruption and posteruption events of Mount Pinatubo contributes to said
problem. In addition, because of lahar and theconstruction of Tail Dike west of the city, the flow ofwater of San Fernando River was obstructed causing
floodwater to backflow that aggravates the condition and rapid urbanization thatincreased runoff coefficient.

The August 2004 flood event affecting Central Luzon
particularly the City of San Fernando which can be attributed
to heavy rains cause by Southwest Monsoon brings theeconomy to a major setback as it hampers activities in all
sectors in the area.
In the identified flood prone area, 16 barangay experienced
inundation depth ranging from 0.30 m. to 2.00m withcorresponding inundation duration of around 1 week to 3months.
IV.

Drainage System

The drainage system in the City of San Fernando consists ofdrainage channels and facilities, namely; creeks, outfalls,
7

open drainage, road gutters, and drainage pumping stations. In the target area,
there are around 159 km in length of creeks and around 45 km length of open
drainage made of concrete.
V.

Profile of San Fernando RiverSan Fernando River (SFR) is located at the southern portionof the City of San Fernando, Pampanga with a total length of
5.84km and an average width of 30.00m. Being the lowest
point in the city, the river absorbs surface water runoff andflood water coming from neighboring Angeles City and Mexico
Municipality through feeder creeks. The main outlets of SFR
are Mapalad Creek with a total length of 3.20km and average width of 20.00m andMatulid Creek with a total length of 3.92km and average with of 30.00m
respectively.

Expected effectivenessThe expected effectiveness of the Flood Hazard Mapping Project are the following:
1. Learning from the past experiences.
FHM will entice people to learn from past flooding
experiences and they will be reminded of the good andbad things happened in times of disaster. These trials
in life will encourage them to work hard to avoid such
experiences again in life.
2. Awareness of the present situation.
FHM will enlighten people of their present situationin the area where they are residing. They will beaware of the necessary information for the safety of
their family: the safe routes, danger zone, evacuation
centers, important telephone nos. etc. In that way,
they will more alert and entice to participate in drill
exercise for disaster preparedness.

3. Preparedness for the future flooding scenario.

FHM will inspired people to pro-actively prepare
themselves to any flooding scenario to avoid negative
past experiences during disaster. In that way, thedisaster risk management team life will be moreeasier for they may identify people who are capable ofhelping themselves (self help), the people who canhelp each other (mutual help) and people with special needs (publicassistance) during disaster.
Through this project, the people will feel the concern of the government, that thisproject is for the welfare of the community thus they will feel the sense of belonging
and safety in the city. Flood Hazard Map will remind us the most vulnerable area toprotect with. If the weakest points are proactively mitigated, damage to lives andproperties will be successfully avoided. New investment and economic activity will
be more active in the area and people will live peacefully, happily and in harmony
with the environment.
In summary, Flood Hazard Mapping Project in the City of San Fernando,
Pampanga can be concluded to be economically viable considering the cited benefits
acquired through this project. In addition, the propose project has more highpositive impact than less negative impact. Thus, I am recommending for theapproval, funding and implementation of this project.
