Pariaman City is in West Sumatra Province, with a land area of 73.36 km² and a coastline length of 12.7 km. The local government has constructed coastal protection structures such as groins, jetties, and revetments to safeguard the shoreline and preserve the coastal ecosystem from damage caused by waves, abrasion, accretion, and erosion. Over time, several components of the groin, jetty, and revetment structures have experienced deterioration, necessitating repair. This study aims to identify the damage to each structure, propose appropriate repair solutions, and estimate the repair cost budget.The assessment of damage, repair guidelines, and prioritization of interventions are carried out based on the Regulation of the Minister of Public Works No. 09/PRT/M/2010 and the Circular Letter of the Minister of Public Works No. 01/SE/M/2011. This study found that the primary cause of damage was the disintegration of the rubble arrangements in several sections. The recommended repair solution involves adding new rocks and rearranging existing ones to interlock securely. The estimated cost of repairs is IDR 662,014,140.00.
