In stormy weather, Jerome Kerivan finds himself wondering how much more pressure his eight-year-old home can take. “The last two to four years, there’s a lot more spray coming in over the breakwater that strikes the house,” he said of his sea-facing home near the Placentia lift bridge. “I get concerned. … What’s going to happen? The biggest concerns I have are the shingles and everything on the house.” The storms are more frequent and the winds are a lot stronger, said Kerivan, a retired fisherman. Like many other residents, Kerivan credits a seawall built decades ago following severe flooding in the 1980s with keeping Placentia — much of which is below sea level — protected from potentially devastating flooding.
