Coated steel sheet piles line both channel banks of Huntington Beach (D01) and Talbert (D02) Channels between Brookhurst Street and Adams Avenue with sheet piles continuing along Talbert (D02) Channel upstream to Yorktown Avenue. Cathodic protection (CP) systems were also installed during original construction to provide added corrosion protection to these sheet piles. Despite these measures, over the years the sheet piles began to exhibit failure of the protective coatings and corrosion primarily within the “splash zone”; the area on the sheet pile surface most susceptible to repeated wetting and drying due tidal influence. The project proposed to mitigate and repair portions of these coating failures and to make changes to the cathodic protection systems. Remediation efforts included providing additional electrical continuity between sheet piles, installation of additional anodes for the CP system, and implementation of a coatings maintenance program to touch-up areas showing visible signs of coatings failure.
