Results from Site Visits and Household Surveys

A series of household surveys and site visits were performed in the target barangays in the city (i.e., Barangays Atlag, Bagna, Santo Rosario, and Pamarawan).

Criteria

Based on the gathered data, the search area for the pilot locations, and the effectiveness of Nature-based Solutions (NbS), a framework is established to assess locations and potential pilot measures against set criteria.

Multi Criteria Analysis

For this project, a multi criteria analysis (MCA) has been utilized to understand the hazards, risks, and social dimensions associated with the pilot locations.

Shortlisted Pilot Locations

Based on initial site visits, household surveys, and discussion with stakeholders, a total of eight (8) pilot locations were considered as illustrated in the figure below. Following the MCA, it has been determined that Brgys.

Solutions

Flooding can cause significant disruptions and damages to human infrastructure; however, it is a natural process vital to many ecosystems. Floodwaters carry sediments – particles like sand, silt, and clay across various landscapes.

Pilot Location: Bagna/Panasahan

Pilot Location: Pamarawan

Methods

This chapter outlines the general practices for implementing the concept designs presented in the following section.

Concept Designs

In this section, the conceptual designs of the NbS interventions are presented for the two (2) pilot locations, particularly for: (i) green embankment; (ii) sediment trapping; and (iii) enhanced breakwaters.

Tasking and Budget Estimates

To develop the present conceptual designs into detailed engineering designs and working pilots, it is important to have a budget estimate of the proposed work items to be undertaken by the City LGU of Malolos for them to include in their allocation
