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

₱291,829 per linear m= 1.9x the Region II median (n=146)

Contract cost ₱42,606,976 ÷ 146 linear m read from the DPWH title (“STA. 1+300-STA. 1+446”; station range length (Sta. a+b to c+d)). National percentile: 87. Higher unit cost can have legitimate causes (terrain, design, scope not stated in the title); this is a comparison, not a finding. Methodology

Outside mapped flood-hazard zones · Cagayan

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