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

₱75,969 per linear m= 1.0x the Cordillera Administrative Region median (n=212)

Contract cost ₱49,000,000 ÷ 645 linear m read from the DPWH title (“Sta. 88 + 535 - Sta. 88 + 680; Sta. 89 + 133 - Sta. 89 + 633”; station range length (Sta. a+b to c+d)). National percentile: 26. 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

Outside mapped flood-hazard zones · Apayao

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