Kimberly Sherertz and her late husband, William Sherertz, shared a number of interests, including their mutual enthusiasm for boating on the Columbia RiverBut the Battle Ground widow and mother of two didn’t share her husband’s passion for the $5 million fine-dining venue he envisioned for Washougal’s waterfront.Sherertz said she just doesn’t have the drive to open and operate the multimillion-dollar Black Pearl restaurant that William financed and broke ground on last fall. That’s why she is trying to lease or sell the two-story restaurant’s shell. It was supposed to open this summer on the former site of Washougal’s longtime Parker House Restaurant, overlooking the marina at the Port of Camas-Washougal.“I am just so sad that he couldn’t do this,” Kimberly Sherertz said.William Sherertz, chairman and chief executive officer of Vancouver-based Barrett Business Services Inc., died unexpectedly on Jan. 20. He was 64 years old.At first, Kimberly Sherertz wasn’t sure what to do with the $5 million restaurant project. The 12,000-square-foot building is part of her husband’s estate, which he left to his wife, the couple’s son, Cole; and their daughter, Elizabeth; as well as William’s two daughters, Alex and Sarah.Overwhelmed by decisions, the family finally decided “to push the pause button,” Kimberly Sherertz said.That has meant allowing contractors to finish the building’s exterior walls and roof, install doors and erect the building’s three-sided glass front with its views of Mt. Hood, the 350-slip marina and the Columbia River, just upstream from Steamboat Landing and Cottonwood Beach. Before they put the project on mothballs, construction crews laid gravel down and leveled the area surrounding the east and north sides of the structure.
