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

₱156,384 per linear m= 0.7x the Region III median (n=202)

Contract cost ₱41,598,060 ÷ 266 linear m read from the DPWH title (“STA. 0+000 - STA. 0+266.00”; station range length (Sta. a+b to c+d)). National percentile: 63. 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

Low flood hazard · Bulacan

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