Unit-cost benchmark · Flood wall / dike / revetment, cost per linear meter (flood control structure)

₱137,088 per linear m= 0.9x the Region II median (n=146)

Contract cost ₱95,961,825 ÷ 700 linear m read from the DPWH title (“STA. 0+000 - STA. 0+700”; station range length (Sta. a+b to c+d)). National percentile: 58. Higher unit cost can have legitimate causes (terrain, design, scope not stated in the title); this is a comparison, not a finding. Methodology

Site vs flood hazard · Project NOAH 100-year map

High flood hazard · Isabela

Based on the coordinates published with the DPWH record and NOAH file Isabela.zip. Pins are sometimes placed at the town center rather than the site. NOAH data (ODbL) · Need vs spending by province
