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

₱101,664 per linear m= 1.0x the Region XI median (n=68)

Contract cost ₱60,795,000 ÷ 598 linear m read from the DPWH title (“STA. 17+789-STA. 18+387”; station range length (Sta. a+b to c+d)). National percentile: 41. 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 · Davao del Sur

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