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

₱129,556 per linear m= 1.0x the Region V median (n=61)

Contract cost ₱15,805,807 ÷ 122 linear m read from the DPWH title (“STA. 17+404.00 - 17+526.00”; station range length (Sta. a+b to c+d)). National percentile: 55. 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

Medium flood hazard · Camarines Sur

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