Implementing Arrangement:  
In response to the official request of the Republic of the Philippines, the Government of Japan has decided to conduct the Feasibility Study of the Flood Control Project for the Lower Cagayan River in the Republic of the Philippines. The Implementing Arrangement of the technical cooperation for the Study was agreed upon between the Department of Public works and Highways and the Japan International Cooperation Agency on December 17, 1999. 

In accordance with the Implementing Arrangement, JICA dispatched the Study Team to undertake the Study in the Philippines.

Background:
The flood inundation problem has been a main constraint in the promotion of socio-economic development and improvement of the living condition of the people in the Cagayan River basin. The Government of the Philippines (GOP) has requested the Japanese Government (GOJ) for the technical assistance to conduct the feasibility study of the flood control project for the Lower Cagayan River. In response to the request, the GOJ decided to conduct the feasibility study (the Study) and the Study commenced in March 2000.

Objectives:
The objectives of the Study are:
1) to carry out the feasibility study of the Lower Cagayan River Flood Control to improve the socio-economic status of the area through mitigation of flood and reduction of flood damages, and
2) to perform technology transfer to the Philippine counterpart personnel in the course of the Study. 
The Study also covers a review of the Master Plan on the Cagayan River Basin Water Resources Development executed in 1985 to 1987 (1987 MP). The main components of the review of the 1987 MP are flood control, land use and watershed management.

Study Area:  
The area for the feasibility study is the Lower Cagayan River area. It covers the river course and its riparian area where flow regime of the Cagayan River will be affected by widening of the Magapit Narrows. The whole Cagayan River basin is, however, to be investigated to formulate an appropriate flood control plan in view of the watershed conservation and comprehensive river planning.

Study Schedule:  
The study covers the Master Plan Study on the Cagayan River basin Water Resources Development executed in 1985 to 1987 and formulation of a technically, economically and environmentally viable flood control plan in conjunction with a land use plan. 

In order to achieve the objectives mentioned above, the overall work schedule of the Study is divided into three phases:

1. First Year of the Study (March 2000 - June 2000)

a) Collection and review of existing data and information   
b) Workshop (1)   
c) Supplemental survey and investigation

- River cross section survey and aerial photography     
- River morphologic survey     
- Flood damage survey    
- Geological survey     
- Soil survey    
- Material survey    
- Land use survey    
- Environmental and basic social impact survey

2. Second Year of the Study (July 2000 - March 2001)

a) Continuation of collection and review of existing data and information   
b) Continuation of survey and investigation

c) Workshops (2) and (3)   
d) Supplemental survey on river condition and land use during the dry season   
e) Study and Analysis

f) Formulation of draft flood control plan, draft watershed conservation plan, land use plan and supporting programs

3. Third Year of the study (April 2001 - January 2002)

a) Technology Transfer Seminars (1) and (2)   
b) Workshop(4)   
c) Formulation of flood control plan, watershed conservation plan, land use plan and supporting programs   
d) Preliminary design, construction planning, operation and maintenance planning, cost estimate and financial planning   
e) Environmental survey and study
