Contaminants from historic mining practices in Idaho’s Coeur d’Alene Basin washed downstream and settled in soil and sediment along some Spokane River beaches.

The U.S. Environmental Protection Agency (EPA) conducted studies of the mining contaminants in the Coeur d’Alene Basin and began a wide-spread cleanup of the Bunker Hill Mining and Metallurgical Superfund Site. As part of the EPA study and studies Ecology conducted, 9 beaches in Washington were cleaned up, including Flora Road. 

The site is located about 5 miles west of the Idaho border along the southern bank of the Spokane River at Flora Road. The site is accessed from the Centennial Trail by a narrow path that has trees and brush on both sides.


    The mining-related contaminants include arseniccadmiumlead and zinc.

    The Flora Road Site is on the southern bank of the Spokane River (where path and boulders are located)

    Ecology completed cleanup work at the Flora Road site in 2009. A one foot cap of gravel material was placed over contaminated sediments along the Spokane River bank. Boulders moved during the construction were replaced. A portion of the access path from the Centennial Trail to the beach was enhanced with gravel material.   

    Spring run-off in 2011 damaged portions of the protective cap that was placed over contaminated sediments. The 2012 project enhanced the previous work with an engineered cap that is designed to prevent future erosion.

    Ecology will conduct a periodic review at least every five years following site cleanup, as required by the Model Toxics Control Act. The purposes of the review are to evaluate site conditions and ensure the cleanup continues to protect human health and the environment.
