LA County flood officials have wanted to clear the debris for years. In 2014, the Los Angeles County Board of Supervisors approved a five-year plan to clean 2.4 million cubic yards of sediment out of the dam site to alleviate flood risk. Work was halted, however, when Pasadena residents concerned about pollution and construction noise opposed the project. The nonprofit Arroyo Seco Foundation sued the city over the sediment removal plan—they prefer the Pasadena City Council’s plan that scales back the amount of sediment removed by half and spreads the project out over several more years. No progress will be made on either sediment project until the lawsuit is settled, likely after the El Niño rainy season.

Tim Brick, managing director of the Arroyo Seco Foundation believes the threat is exaggerated and not worth the hassle to the neighborhood from hundreds of trucks hauling out sediment. The foundation prefers a “sensible slow program” that will “minimize the impacts.” Meanwhile, homeowners in the rich Aroyo Seco area are dealing with the flood information, some hearing about it for the first time.

Others know of the risk, but have little recourse should they become victim of a flood. The federal government does not require the purchase of flood insurance for houses in the area because the county classifies the flood danger as being “temporary” because their impending plans to remove the sediment would solve the problem, the same plans that have been frozen by lawsuits until well after the heavy rains have fallen. —Jeff Wattenhofer
