Chapter II: Technical Study

A. Nature of the Project

The "Evacuation Center Route Planning for the Permanent Evacuation Center at Barangay Poblacion E, Municipality of Rosario, Province of Batangas" is a strategic initiative aimed at ensuring the safety and well-being of the residents during flood emergencies. This project emphasizes the integration of Geographic Information Systems (GIS) for effective disaster response, focusing on the design and validation of evacuation routes leading to the permanent evacuation center.

Evacuation route planning is a critical component of disaster risk reduction, particularly in flood-prone areas like Rosario, Batangas. The project will leverage GIS technology to map flood hazards, assess road networks, and identify the safest and most efficient routes for evacuation. This technical study outlines the methodologies, baseline data, and constraints involved in the project.

B. Baseline Studies

Flood Risk and Historical Data

Flooding in Rosario, Batangas, is influenced by seasonal typhoons, monsoon rains, and the proximity of waterways. Historical data on past flood events will be analyzed to identify high-risk zones. GIS tools will be employed to create flood susceptibility maps, taking into account rainfall patterns, elevation, and drainage systems.

Road Network and Infrastructure Assessment

The existing road network will be assessed for its capacity, condition, and accessibility during flood events. Factors such as road elevation, surface quality, and potential bottlenecks will be analyzed. The study will also consider alternative routes, including secondary roads and pathways, to ensure multiple evacuation options.

Evacuation Center Suitability

Barangay Poblacion E was selected for its central location, accessibility, and existing infrastructure capable of housing evacuees. The study will validate its suitability based on proximity to high-risk areas, structural integrity, and available amenities such as water supply, sanitation, and medical facilities.

C. Constraints

Environmental Constraints

Flood-prone areas, seasonal weather patterns, and natural barriers such as rivers and hills pose significant challenges to evacuation planning. The project will need to account for these factors when designing routes to ensure they remain viable under different flood scenarios.

Safety Constraints

Safety considerations include ensuring that evacuation routes are free from hazards such as landslides, flooding, and structural weaknesses. Data accuracy is crucial, and up-to-date information on flood risks and road conditions must be maintained.

Project Constraints

Limited financial resources, data availability, and time constraints are notable challenges. The project must optimize available resources while ensuring the reliability of the evacuation plan. Coordination with local authorities and stakeholders is essential for successful implementation.
