Frustrated by continual delays in refurbishing the Whittier Narrows Dam, U.S. Rep. Grace Napolitano summoned the commanding general of the U.S. Army Corps of Engineers to her office in Washington D.C. last week. Her tete-a-tete with Lt. Gen. Todd Semonite produced the same refrain the agency has been telling the 1 million people threatened by flooding if the eroding dam were to fail: The $500 million project will be completed in 2025 — at the soonest. Not satisfied, Napolitano, D-El Monte, who is 82, said she’s been working on getting the Army Corps to hasten the project for the last 12 years and wondered if she’d be alive by the time it gets finished.
